You have to add/subtract all the common variables the answer is 3x+7y
Answer:
53, 55, 57, and 59
Step-by-step explanation:
Let the numbers be
x, x +2, x +4, and x+6. Then
x + x+2 + x +4 + x + 6 = 224 Combine like terms
4x + 12 = 224 Subtract 12 from each side
4x = 212 Divide each side by 4
x = 53
The four consecutive integers are 53, 55, 57, and 59.
<em>Check:
</em>
53 + 55 + 57 + 59 =224
Answer:
11.75
Step-by-step explanation:
The required triangle is attached below :
The triangle AFE has it's by the mid segment as BD ;as B is the mid-point of line EA ; and D is the mid-point of line FA ;
HENCE, The Length of the midsegment BD = 1/2FE
Hence, BD =. 1/2 * 23.5
BD = 23.5 / 2 = 11.75
For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.
IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

We apply distributive property:

So, on Saturday she spent 5 hours.
Answer:

convert 7 1/2 to a decimal which becomes 7.5 and here are the 3 different expressions to find the garden's perimeter.
1) p= 2(l + w)
2) p= 2 x 90+ 2 x 7.5
3) p= 90 + 7.5 + 90 + 7.5
