To find the perimeter of a rectangle you can multiply the length by 2 and the width by 2, or you can add the four sides together.
The wrong equation is w + 3w = 90 because it only has one width and one length, which would be half the total perimeter.
Answer:
he should set up the problem so he can find the amount he has left to save. so 129.85 - 89.25 = X or the amount he needs.
he could also do 89.25 + X = 129.85
5:9 and 5 to 9 are two other ways to write the fraction 5/9.
I hope this helps:)
Answer:
4.85
Step-by-step explanation:
The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.
<h3>What is the Slope?</h3>
The slope of a line (m) = rise/run = change in y / change in x.
Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:
Slope (m) = (5 - 3)/(2 - 1)
Slope (m) = (2)/(1)
Slope (m) = 2
This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3
