When u simplify an expression all the way algebraically
Answer:
Step-by-step explanation:
Line DE is parallel to line AG.
Also, triangle ABG is similar to triangle to triangle DBE.
Therefore,
AB/DB = GB/EB = AG/DE
AB = 5 + 6 = 11
GB = 9 + x
Therefore,
11/6 = (9 + x)/9
Cross multiplying, it becomes
11 × 9 = 6(9 + x)
99 = 54 + 6x
Subtracting 54 from the Left hand side and the right hand side of the equation, it becomes
54 - 54 + 6x = 99 - 54
6x = 45
Dividing the Left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 45/6
x = 7.5
Answer:
8 pounds of apples.
Step-by-step explanation:
5 pies need 2 pounds of apples.

Answer:
x = 3
Step-by-step explanation:
we know that if we have an original line and we are finding the perpendicular we know that the slope of the second line is gonna be the negative reciprocal of the first line and given that we know it must be perpendicular to the original line it will be heading downwards on the y axis with no slope so instead of y equals it will be x equals and we know that our x value of the point given is three so the answer is x = 3
