A) 2 height + 2  width = 60
B) 2 * height = base (width)
Multiplying equation B) by minus 1
B) -2 * h + w = 0 then adding this to equation A)
A) 2h + 2w = 60
3 * width = 60
width = 20
height = 10

C) is the correct answer because since the base is 2 times the height, this means that the base is larger than the height. And when u look at c, and u add up all the sides( 10+10+20+20) you get the perimeter, 60 cm

Victor has saved $89.25 for the bicycle that he wants. The bicycle costs $129.85. Victor
serious [3.7K]

Answer:

Victor's equation did not correctly model the problem.

The equation that correctly modeled the problem:

$129.85-$89.25=$40.60

Step-by-step explanation:

The amount required for bicycle purchase by Victor is $129.85 out of which $89.25 has been saved,in other words,the balance required for Victor to reach his target purchase price is the difference between the total cost of $129.85 and the $89.25 already saved.

The balance required=$129.85-$89.25=$40.6

This shows that the equation put forward by Victor is wrong.

An equation that correctly represents the problem is the difference between the target savings and the amount already saved as stated above

B is the midpoint of line segment AC. Find the measure of line segment AC. *25427084
iris [78.8K]

Answer:

84 units

Explanation:

If B is the midpoint of line AC, then B divides AC into two equal parts (AB and BC).

Therefore:

AB=BC

2x-8=x+17

2x-x=17+8

x=25

Therefore, the measure of the line segment AC

=2(2x-8)

=2(2(25)-8)

=2(50-8)

=2(42)

AC=84 units
