Answer:
x = 4.5
Step-by-step explanation:
thesetwo triangles are similar to we can create a proportion from corresponding sides as follows:
4/9 = 2/x
cross-multiply:
4x = 18
x = 4.5
Answer:
10x + 7 = 85
8 packs
Step-by-step explanation:
Let's let packs = x
10 shirts in a pack = 10x
So we know that since he has 7 packs already, that can be our y-intercept in this equation
This will leave us with 10x + 7
And since we can't have a partial amount of packs, we round up to 8 total packs
Hope this helps
Hello!
First of all, let's look at the x value 1. There is one point located at y value 2. We will plug our x value into each equation and see if it has an outcome of two.
A. 2≠-2
B.2≠1
C.2≠0
D.2=2
E.2≠4
F.2≠3
Therefore, D is the correct equation.
