Geraldine borrowed $120 from her mom. For every $10 she borrowed, she owes her mom an additional $1.50. How much does Geraldine have to pay back, in addition to the original $120?

$18

Step-by-step explanation:

First, divide 120 and 10. That is 12. Now, multiplt 12 and $1.50 together. That is $18.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the answer is 2/54
