Answer: X = 19
Step-by-step explanation: it is a three equation system, the problem is you don't have the third equation, so we have to infer it, and it's: PRQ + QRS = 180.
then we do as follows:
Answer: 11 boxes of cards for $72
Step-by-step explanation:
Brennan's equation would be
y=6x+6
Gabriel's Equation would be
y=5x+17
when they spend the same amount the equations will be equal
6x+6=5x+17
x+6= 11
x=11
so 11 boxes they would spend the same
To figure out cost, put 11 into the first equations
y=6(11)+6= 66+6= 72
y=5(11)+17= 55+17 = 72
so they each spent $72
Answer:
150
Step-by-step explanation:
150 is greater than 100 and less than 1000.
150 can divide by 10.
The quotient of 150 is less than 100 but greater than 1.
Answer:
$360
Step-by-step explanation:
Find 3% of 500 = 15
Multiply 15 by 24 = 360
Answer:
-5
Step-by-step explanation:
its the same as adding positive numbers but with a minus sign so -3+(-2)= -5
