Answer:
49y
Step-by-step explanation:
7 x 7 x y= 49 x y = 49y
The equation for the perimeter of a rectangle:
P = 2L + 2W
We’re given P and L and asked to find W:
15x + 17y = 2(7/2x + 7y) + 2W
15x + 17y = 7x + 14y + 2W
2W = 8x + 3y
W = 4x + 3/2y
Answer is A.
Answer:
c = 2
Step-by-step explanation:
From the statement we have that If 14 is 7 times a number c, we can write the following equation:
7c = 14. Solving for c, we have:
c = 14/7 = 2
Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8
