Answer:
x=0
Step-by-step explanation:
9x-7=-7
Add 7 to each side
9x -7+7 = -7+7
9x = 0
Divide each side by 9
9x/9 = 0/9
x = 0
Answer: x = 0
Step-by-step explanation:
9x -7 = -7 First add 7 to both sides
+7 +7
9x = 0 Now divide both sides by 9
x = 0
what is bigger 5.6% or square root of 27
square root of 27 is bigger.
What is percentage ?
In math, one percent is equal to a hundredth part; thus, 100 percent represents the entire amount and 200 percent specifies twice that amount
First calculating square root of 27 :
[tex]\sqrt{27}=5.196[/tex]
and 5.6 % is 0.056
clearly [tex]\sqrt{27}[/tex] is greater than 5.6%

Determine whether the dilation from Figure ABC to Figure A'B'C' is a reduction or enlargement Then find its scale factor.
Answer:
This dilation from Figure ABC to Figure A'B'C' is a reduction, with a scale factor of 1/3.
Step-by-step explanation:
The points for Figure ABC are
A =(3,3)
B =(6,3)
C =(6,-3)
The points of Figure A'B'C' are
A' =(1,1)
B' =(2,1)
C' =(2,-1)
To get from (3,3) to (1,1) we have to multiply by 1/3, (6,3) to (2,1) multiply by 1/3, and so on.

Molly swimming in a pool that is 25 m long. She swim 24 length of the pool and 40 minutes. What was the rate of speed in meters per hour?
Can you please tell me how you got the answer thank you
Answer:
the length she swim = 24m
time taken = 40 minutes =40/60hour
rate of speed= 24/(40/60)= 36mper hour
Step-by-step explanation:
Step-by-step explanation:
Because Molly swam across the pool 24 times, she swam a total of 24 * 25m = 600 meters.
600m in 40 minutes
Since 40 minutes * 1.5 = 60 minutes = 1 hour,
600m * 1.5 = 900m.
Hence Molly's speed was 900m/h.

Se distribuyen 400 bolsas en tres urnas sabiendo que la primera tiene 80 menos que la segunda y esta tiene 60 menos que la tercera, averigua cuántas bolsas tiene cada una.
Answer:
Primeras urnas = 60 bolsas
Segundas urnas = 140 bolsas
Terceras urnas = 200 bolsas
Step-by-step explanation:
Deje que las urnas se representen de la siguiente manera
Primeras urnas = a
Segundas urnas = b
Terceras urnas = c
Se nos dice en la pregunta
400 bolsas se distribuyen en tres urnas
Por lo tanto,
a + b + c = 400 bolsas ......... Ecuación 1
Por la pregunta sabemos que
1) El primero tiene 80 menos que el segundo
a = b - 80
2) Y este segundo tiene 60 menos que el tercero
b = c - 60
Por tanto, c = b + 60
Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1
a + b + c = 400 bolsas ......... Ecuación 1
b - 80 + b + b + 60 = 400 bolsas
Recopilar términos similares
b + b + b - 80 + 60 = 400 bolsas
3b = 400 + 80 - 60
3b = 420
b = 420/3
b = 140 bolsas
Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas
Dado que a = b - 80
a = 140 bolsas - 80
a = 60 bolsas
Por lo tanto, el número de bolsas en la primera urna = 60 bolsas
Dado que c = b + 60
b = 140 bolsas
c = 140 + 60
c = 200 bolsas.
El número de bolsas en las terceras urnas = 200 bolsas.

What is 20-12x=8-10x
Answer: x= 6
Step-by-step explanation:
20 -12x = 8 - 10x Add 12x to both sides
+12 +12
20 = 8 + 2x subtract 8 from both sides
-8 -8
12 = 2x Divide both sides by 2
x = 6
Answer:
x=6
Step-by-step explanation:
20-12x=8-10x
Add 12x to each side
20-12x+12x=8-10x+12x
20 = 8 +2x
Subtract 8 from each side
20-8 = 8+2x-8
12 = 2x

maria brought a blouse on sale for 20% off. the sale price was $21.76. what was the original price? round to the nearest hundredth.
Answer: $27.20
Step-by-step explanation:
She bought a blouse for 20% off so it means that she paid 80% of the original price.We can then set up the equation
80% of x = 21.76 where x is the original price so solve for x
0.8x = 21.76
x = 27.20
Which means the original price is $27.20

Answer:
11
Step-by-step explanation:
Absolute value only applies to negative numbers. It will make negative numbers positive. As you can see in the problem, they are asking for the absolute value of positive numbers, so you can ignore the absolute value signs and add normally.

Answer:
see explanation
Step-by-step explanation:
Given
2(2x - 1) = 3(x - 6) ← distribute parenthesis on both sides
4x - 2 = 3x - 18 ( subtract 3x from both sides )
x - 2 = - 18 ( add 2 to both sides )
x = - 16
-------------------------------------------------------------------
Given
4(5 - 7b)- 4 = - 3(1 + 3b) ← distribute parenthesis on both sides )
20 - 28b - 4 = - 3 - 9b , that is
16 - 28b = - 3 - 9b ( add 9b to both sides )
16 - 19b = - 3 ( subtract 16 from both sides )
- 19b = - 19 ( divide both sides by - 19 )
b = 1
Answer:
[tex]\sf 1) \ \ \ \ \huge\boxed{\sf x = - 16}[/tex]

Which equation represents a line that passes through (2, -1) and has a slope of 3?
The area of a square is 117 square meters which best represents the length of a side.
The best representation for the length of a side of the square is 10.82 meters.
Given that the area of the square is 117 square meters.
Let's denote the length of the side of the square as "s."
The formula for area of square
= s²
Substituting the value of area of square 117 square meter back to the formula
117 = s²
Take the square root of both sides:
s = √(117)
s ≈ 10.82 meters
So, the length of a side of the square is 10.82 meters.
