Daniel cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 45 inches. How long is each side of the original square cake?
1 answer:
Answer:
15 inches
Step-by-step explanation:
As the square cake was cut in two equal pieces, we have that one side of the rectangle is the double of the other side, so we have that:
2*Length + 2*Width = 45
Length = 2*Width
So using the value of length in the first equation, we have:
4*Width + 2*Width = 45
6*Width = 45
Width = 7.5
Length = 2*Width = 15
So each side of the original cake is equal to the length of the rectangle pieces, that is, 15 inches.

If you were to multiply 8 into 30 you'd get it.
G is the answer because if you set x as the value of B, then x+(x+10)+(x+30)=180 so x=46.67. then you add 10 to that because the value of A is 10 more than B
Answer:
x = -1/7 Or 0.143 (3 dec)
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3
= 24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
21x/21 = -3/21
x = -1/7
Or 0.143 (3 dec)

Step-by-step explanation:
5(3m + n) = 15m + 5n
Answer:
Step-by-step explanation:make equations on : (x)+(x+5)(2x)=100
Then solve: 4x+5=100
X=23
Plug in her equation: 23+5= 28
So she is 28 years old
