Answer:
if you don't its still right though
Step-by-step explanation:
only if you don't simplyfy if you do then just subtract and you will get a another answer which both are right
Answer:
y= - 5x+40
Step-by-step explanation:
I graphed this out. Remember that in parallel lines, the slopes are always the same.
Answer:
The answer is 225
Step-by-step explanation:
Because you first need to subtract 350-125 and you get 225
Answer: -2
(-5)(-1)x=(10)(-1)
5x = -10
x = -2
Answer:
30cm x 72 cm
Step-by-step explanation:
The perimeter is the measurements of all sides added together. Let's start by dividing the perimeter by 2, so we have the sum of the length and width. This gives us 102cm. Let's call the width <em>x</em>, and the length <em>y</em>. We know <em>y</em> is <em>x</em> times 2 plus 12. (2x + 12) So, we know [x + y = x + (2x + 12)]. So let's solve.
x + y = x + (2x + 12)
102 = x + (2x + 12)
102 = 3x + 12
102 - 12 = 3x + 12 - 12
90 = 3x
90/3 = 3x/3
30 = x
The width is 30cm.
