Answer:
C
Step-by-step explanation:
Your answer is correct.
You spent 30 dollars last month, and you spent 140% of what you spent last month. Basically, 30 + 30(140%)=42.
The length of the enlarged photo would be 21 in.
For the original picture, we can represent the length as x and the width as x-3. Then we can use the perimeter equation: p=2w + 2l
22 = 2x + 2(x-3)
22 = 4x - 6
x = 7
Since the original length is 7 and the length is tripled, the new length is 21 in.
Answer:
repeating decimal
Step-by-step explanation:
The value of x in the equation is 26.7
<h3>How to solve an equation?</h3>
0.75x + 1.5y = 40
−1.5x − 1.5y = −60
add both equation to eliminate y .
Therefore,
−1.5x + 0.75x = -0.75x
1.5y + (- 1.5y) = 0
40 + (-60) = -20
Hence,
-0.75x = - 20
divide both sides by -0.75
-0.75x / -0/75 = - 20 / -0.75
x = - 20 / -0.75
x = 26.6666666667
x = 26.7
