Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.

Answers

Answer 1

Answer:

March=49

April=31

May=36

Andrea ran about 116 km

this is about 4 km less than last year

Step-by-step explanation:

I got it right :))

Answer 2

Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.

What is subtraction?

The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given:

Total distance run this year = 120 km,

The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.

Calculate the total distance = 48.7 + 31.2 + 35.66

The total distance this year = 115.56 or 116 km

Calculate the difference as shown below,

Distance = 120 - 116 = 4 km,

Thus, she ran 4 km extra last year.

Tavon has a gift card for $115 that loses $2.50 for each​ 30-day period it is not used. He has another gift card for $95 that loses $2 for each​ 30-day period it is not used.

Answers

The question is incomplete:

Tavon has a gift card for $115 that loses $2.50 for each​ 30-day period it is not used. He has another gift card for $95 that loses $2 for each​ 30-day period it is not used.

Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.

Answer:

115-2.5x=95-2x

The value of the gift cards will be equal after 40 30-day periods.

Step-by-step explanation:

From the information given, you can write the following equation:

115-2.5x=95-2x, where x is the number of 30-day periods the gift card is not used.

Now, you can solve for x:

115-95=-2x+2.5x

20=0.5x

x=20/0.5

x=40

According to this, the answer is that the value of the gift cards will be equal after 40 30-day periods.

my number?

Answers

Answer:

Your number is 0.5, 2/4, or 1/2

Step-by-step explanation:

You need to set up your equation and then solve for x. We know that quadruple your number (x) plus 7 equals -5. Quadruple your number is the same as multiplying by 4. So it would be 4x + 7 = -5. We add seven to both sides and that would leave us with 4x = 2. Then we divide both sides by 4 to get x on it's own. x = 2/4 or 1/2

9. If LK MK, LK = 7x - 10, KN = x + 3, MN = 9x - 11, and KJ = 28, find LJ.

Answers

Answer:

[tex] LJ = 46 [/tex]

Step-by-step explanation:

Given:

[tex] LK = MK [/tex]

[tex] LK = 7x - 10 [/tex]

[tex] KN = x + 3 [/tex]

[tex] MN = 9x - 11 [/tex]

[tex] KJ = 28 [/tex]

Required:

LJ

Solution:

Step 1: create an equation to find the value of x

Since we are given that LK = MK, and LK = 7x - 10, let's find the expression for MK to get an equation.

[tex] MK + KN = MN [/tex] (segment addition postulate)

[tex] MK = MN - KN [/tex] (Subtract KN from each side)

[tex] MK = (9x - 11) - (x + 3) [/tex] (subtitution)

[tex] MK = 9x - 11 - x - 3 [/tex]

[tex] MK = 9x - x - 11 - 3 [/tex]

[tex] MK = 8x - 14 [/tex]

LK = MK, therefore,

[tex] 7x - 10 = 8x - 14 [/tex]

Subtract 8x from each side

[tex] 7x - 10 - 8x = 8x - 14 - 8x [/tex]

[tex] -x - 10 = -14 [/tex]

Add 10 to both sides of the equation

[tex] -x - 10 + 10 = -14 + 10 [/tex]

[tex] -x = -4 [/tex]

Divide both sides by -1

[tex] x = 4 [/tex]

Step 2: Find LJ

[tex] LJ = LK + KJ [/tex] (segment addition postulate)

[tex] LJ = (7x - 10) + (28) [/tex]

Plug in the value of x

[tex] LJ = 7(4) - 10 + 28 [/tex]

[tex] LJ = 28 - 10 + 28 [/tex]

[tex] LJ = 46 [/tex]

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

[tex]12 =-6x+3x[/tex]

Note ; When a number is crossing over an equality sign ; the sign will always change

Step 2 ;

Simplify

[tex]-6x +3x =-3x\\\\ 12=-3x[/tex]

Step 3 ; Divide both sides of the equation by -3

[tex]\frac{12}{-3} = \frac{-3x}{-3} \\\\-4 = x[/tex]

The value of the expression 12+(-16)+24-18 is 2, which can be computed using the commutative property.

What is the commutative property?

The commutative property signifies that the order of terms in mathematical expressions does not matters. It applies only to addition and multiplication operations, and not to subtraction and division operations.

How to solve the given question?

In the question, we are asked to evaluate: 12 + (-16) + 24 - 18.

By using the commutative property, we can write the expression

12 + (-16) + 24 - 18, as

= 12 + 24 + (-16) - 18

= 12 + 24 -16 - 18

= 36 - 34

= 2

Step-by-step explanation:

I did the test

The equation of a line with a slope of –2 that passes through the point (6, 8) will be 2x + y = 20.

What is the equation of line?

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The slope is -2. Then the equation of line will be

y = –2x + c

The line is passing through (6, 8), then we have

8 = –2(6) + c

8 = –12 + c

c = 8 + 12

c = 20

Then the equation of line will be

       y = –2x + 20

2x + y = 20
