Answer:
4 x + -43
Step-by-step explanation:
Simplify the following:
7 (x - 4) - 3 (x + 5)
Hint: | Distribute 7 over x - 4.
7 (x - 4) = 7 x - 28:
7 x - 28 - 3 (x + 5)
Hint: | Distribute -3 over x + 5.
-3 (x + 5) = -3 x - 15:
7 x + -3 x - 15 - 28
Hint: | Group like terms in 7 x - 3 x - 28 - 15.
Grouping like terms, 7 x - 3 x - 28 - 15 = (7 x - 3 x) + (-28 - 15):
(7 x - 3 x) + (-28 - 15)
Hint: | Combine like terms in 7 x - 3 x.
7 x - 3 x = 4 x:
4 x + (-28 - 15)
Hint: | Evaluate -28 - 15.
-28 - 15 = -43:
Answer: 4 x + -43
Answer:
4x – 43
Step-by-step explanation:
Which of the expressions has a sum of 15.41? Select all that apply. A. 11 . 38 + 4 . 03 B. 10 + 5 . 41 C. 12 . 38 + 2 . 93 D. 9 . 2 + 6 . 21 E. 7 . 54 + 6 . 87
Answer: A. 11 . 38 + 4 . 03
B. 10 + 5 . 41
D. 9 . 2 + 6 . 21
Step-by-step explanation:
Step 1
Compute the sum of the given options
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
c) 12 . 38 + 2 . 93= 15.31
d) 9 . 2 + 6 . 21 =15.41
e) 7 . 54 + 6 . 87=14.41
Step 2
Eliminate the expressions that do not give a sum of 15.41 , we have
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
d) 9 . 2 + 6 . 21 =15.41
Therefore, the expressions with sum of 15.41 are A, B and D

The definition of a triangle is a polynomial with 3 sides and interior angles adding up to 180.
Using the definition, we can create an equation.
[tex]180=42+31+x[/tex]
[tex]180=73+x[/tex]
[tex]x=107[/tex]
The measure of the third interior angle is 107 degrees.
Hope this helps.
頑張って!
Answer:
107
Step-by-step explanation:
triangle angles = 180
31 + 42 = 73
180 - 73 = 107
7r-9s+2r
evaluate for the following expressions for r=7,s=-2 and t=5
Answer:
91
Step-by-step explanation:
7(7) - 9(-2)+2(7)
=142+49
=91
Answer:
81
Step-by-step explanation:
Simplify it first:
7r-9s+2r = 7(7)-9(-2)+2(7) = 49-(-18)+14
(Since you have 49-(-18) it automatically becomes addition/a positive.)
So you have 49+18=14 which equals 81.
Hope this helps :)
Out of 340 racers who started the marathon, 302 completed the race, 26 gave up, and 12 were disqualified. What percentage did not complete the marathon?
Answer:
11.18%
Step-by-step explanation:
Total = 340
Completed = 302
Not completed = 340 - 302 = 38
Not completed% = 38/340*100% = 11.18%
A quadrilateral has angle measures of 41 52 and 54 which is the measure of the last angle
Answer:
213 degrees
Step-by-step explanation:
A quadrilateral has an internal measurement of angles of 360 degrees. Given that we have 3 measures of the angles, we simply need to find the 4th. This can be accomplished with the following equation:
x + 52 + 54 + 41 = 360
x + 52 + 95 = 360
x + 147 = 360
x = 213
Hence, the measure of the final angle is 213 degrees.
Cheers.

An actor gains 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story. How many pounds is the actor above or below his original weight?
Answer:
5 pounds above his original weight
Step-by-step explanation:
An actor gains 20 pounds for a role in a movie
He loses 15 pounds during the movie to blend with the story line of the movie
Since he gained 20 pounds and loses 15 pounds
20 pounds -15 pounds
= 5 pounds
Hence the actor is 5 pounds above his original weight

x+6/4 + x-3/5 = 5x-4/8
Answer:
x = 7/15
Step-by-step explanation:
x + 6/4 + x - 3/5 = 5x - 4/8
x + x - 5x = -4/8 - 6/4 + 3/5
-3x = -2/4 - 6/4 + 3/5
-3x = -8/4 + 3/5
-3x = -2 + 3/5
-3x = -10/5 + 3/5
-3x = -7/5
x = (-7/5)/-3
x = -7/(5*-3)
x = -7/-15
x = 7/15
Check:
7/15 + 6/4 + 7/15 - 3/5 = 5(7/15) - 4/8
14/15 + 6/4 - 3/5 = 35/15 - 2/4
56/60 + 90/60 - 36/60 = 140/60 - 30/60
146/60 - 36/60 = 110/60

Tommy used a straightedge and a compass to construct a square inside circle C, as shown.
Which of the following steps did Tommy take to construct the inscribed square? Select all steps in the construction.
A Construct a perpendicular bisector of the diameter AB.
B. Construct a perpendicular bisector of the diameter DE.
C. Construct a bisector of ADB to find the location of point E.
D. Use the compass to draw a circle centered at point c.
O E Use the compass to draw two arcs of the same radius centered at point C.
OF Use the straightedge to draw diameter AB of the circle.
OG Use the straightedge to draw lines connecting the endpoints of the two diameters.
Answer:
The correct options are;
A. Construct a perpendicular bisector of the diameter AB
D. Use the compass to draw a circle centered at point C
E. Use the compass to draw two arcs of the same radius centered at point C
F. Use the straightedge to draw diameter AB of the circle
G. Use the straightedge to draw lines connecting the endpoints of the two diameters
Step-by-step explanation:
To draw an inscribed square of a circle, the circle is first constructed. The diameter of the circle is drawn with a straight edge to find the first two vertices of the intended inscribed square. The perpendicular bisector of the diameter is then drawn intersecting the circumference to provide the other two vertices of the square.
The straightedge is then used to draw lines that connect the endpoints of the two diameters to form the inscribed square of the circle.
Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today. Write an inequality that would be used to solve for the least amount of money she needs to deposit to avoid a fee. 524.96 − 32.50 + x ≥ 500 524.96 − 32.50 + x ≤ 500 524.96 + 32.50 − x ≥ 500 524.96 + 32.50 − x ≤ 500
Answer:
524.96 − 32.50 + x ≥ 500
Amount need to deposit = $7.54
Step-by-step explanation:
Given:
Amount in checking account = $524.96
Maintain amount = $500
Amount of check = $32.50
Find:
Amount need to deposit
Computation:
Assume, amount need to deposit = x
So,
For avoiding fee
524.96 − 32.50 + x ≥ 500
x = 7.54
Amount need to deposit = $7.54

Trevor picked 5 ⅗ pounds of cherries. He distributed them evenly into 12 containers. How many pounds of cherries were in each container?
Answer:
7/15
Step-by-step explanation:
For me, it is easier to take the 3/5 and put it in decimal form which is .6 and add the 5 to it, making 5.6, and then in a calculator put in 5.6 divided by 12 and you should get a big decimal that's pretty big but if you have a graphing calculator and convert that to a fraction and you should get 7/15, This is a pretty lazy way of me doing it but that's how I did it.
Suppose f(x) = 2x-1 and g (x) = x + 1/a. Which value(s) of a would make the composite functions commutative? A. 0 B. 2 C. any value of a D. no value of a
Answer:
2
Step-by-step explanation:
A commutative function means that when you insert one function in space of x in the other function, they will equal x. The equation is f(g(x)) = g(f(x)) = x
So, 2([tex]\frac{x+1}{a}[/tex]) - 1 = [tex]\frac{(2x-1)+1}{a}[/tex]
If you multiply both sides by a, you get 2a([tex]\frac{x+1}{a}[/tex]) - a = (2x-1)+1
Simplify it 2a([tex]\frac{x+1}{a}[/tex]) - a = 2x
Add a to both sides 2a([tex]\frac{x+1}{a}[/tex]) = 2x +a
The two as on the left cancel out 2(x+1)=2x+a
Distribute the 2 2x+2=2x+a
Then subtract 2x from both sides 2 = a
Therefore, a = 2

Answer:
The answer is A
Step-by-step explanation:
All you must do is find the correct values in the graph.
The graph which is generated by the table of values x -5,-3,-1,4 and y=2,4,1,0 is on coordinate plane points are at (-5,2) ,(-3,4) ,(-1,1) ,(4,0).
What is function?A function is a relationship between two or more variables having each value of x corresponding to y values. Values of x are known as domain and values of y are known as codomain.
How to graph function?We have been given the following table as under:
x y
-5 -3
-3 4
-1 1
4 0
We have to plot the points -5 ,-3,-1,4 on x axis and corresponding-3,4,1,0 on y-axis.
Hence the graph of given table of values is that on coordinate plane points are at (-5,2) (-3,4)(-1,1)(4,0).
