Answer:
e
Step-by-step explanation:
If you divide 36 by 12, you get 3.
For this to work, whatever the white wax is, it needs to be 3 times as more as 5.
5x3=15
2x + y = 1 . . . (1)
3x - y = -6 . . . (2)
(1) + (2) => 5x = -5 => x = -5/5 = -1
From (1), 2x - 1 = 1 => 2x = 1 + 1 = 2 => x = 2/2 = 1
x = 1, y = -1
Answer:
b. 10
Step-by-step explanation:
The triangles are all similar, so you have ...
hypotenuse/short side = x/4 = 25/x
Cross multiplying gives ...
x^2 = 100
x = 10 . . . . . . . take the square root
Answer:
107%
Step-by-step explanation:
Emma spending 7% more on the sweater than the shoes can be represented by x + 7%, where x is the price of the shoes.
The shoes are worth 100%, or one whole, because you can't buy half a shoe or more than one whole shoe, etc.
So to find how much more the sweater is, add 100% to 7%, or how much more the sweater is.
100% + 7% = 107%
The cost of the sweater is 107% of the cost of the shoes.
