Answer

AB=21

Solution

In the triangle ABC two lines are parallel to side AC.In a triangle a line passing through two side and it is parallel to third side,then this line divides two side in equal ratio.

Here we take any of the parallel line, passing through AB and AC, and parallel to BC.

So we can write, $\\$ $\frac{ 6x+2x+1}{2x}$ = $\frac{18+7.5}{6}$

8x+1=6x+2.5x

x=1/0.5

x=2

Therefore AB = 6x+2x+1+2x =10x+1=21

Answer:

209.5 grams are protein

Step-by-step explanation:

Protein is 25 % or .25

We have 838 grams of peanut butter

25% of it is protein. Multiply the grams by the percent that is protein to determine how many grams are protein

grams protein = total grams times percent protein

=838*.25
