7 + 2(x - 3) + 5x
= 7 + 2x - 6 + 5x <em>distributed 2 into x - 3</em>
= 7 - 6 + 2x + 5x <em>grouped like terms together</em>
= 1 + 7x
You didn't provide an image of the steps but hopefully you can figure it out based on the information I provided.
First, let's look at the ratio.
You also know that for every 8 indoor events, there is 3 field events.
Therefore, the amount of indoor events is 8 on 11 events total, as 8 + 3 = 11
Then, let's look at the actual number of events. If there is 22 events total, you need to solve this proportion :
Answer:
No it's not
Step-by-step explanation:
if you do it correctly and pay attention its not including c so no
Answer:
w = 6
Step-by-step explanation:
Givens
Area = 90
Let the width = w
Let the length = 2w + 3
Formula
Area = L * W
Solution
Area = (2w + 3)*w
Area = (2w + 3)* w = 90 Remove the brackets.
Area = 2w^2 + 3w = 90 Subtract 90 from both sides.
2w^2 + 3w - 90 = 0
This will factor into
(w - 6)(2w + 15) = 0
Only w - 6 will = a zero that makes sense when speaking of an area
w - 6 = 0
w = 6
L = 2*w + 3
L = 2*6 + 3
L = 15
The width is 6
