Answer:126
Step-by-step explanation:
Step-by-step explanation:
18+ 5(2x + 5) = 12
18 + 10x + 25 = 12
43 + 10x = 12
10x = 12 -43
10x = -31
x = -3.1
Answer: B) -48
Step-by-step explanation:
If the system of two linear equations 
has infinitely many solutions , then
For the given system of linear equations : 
We , will have
The value of 
Hence, the value of rs is -48.
Thus , the correct option is B) -48.
Answer:
c = 4x + 35
Step-by-step explanation:
Imagine c = cost

When multiplying decimals, what you do with the decimal point is; C: line up the decimal points
<h3>How to Multiply Decimals?</h3>
A common way to multiply decimals is to treat them as whole numbers, and then position the decimal point in the product. The number of digits after the decimal points in the factors determines where the decimal point is placed in the answer. For example, 0.3 x 0.8 = 0.24.
Now, when multiplying decimals, the most important step is to line up the decimal points. Line up the decimal points so that similar place values are lined up. In other words, the tens place in both numbers should be lined up, the ones place in both numbers should be lined up as well and son.
Thus, option C is the correct answer.
