Are you trying to solve for x and y?
y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3
now that you have x value, plug into the original equation to find y and check with the other.
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17
Answer: $70.50
Step-by-step explanation:
30npm x 125m = 3750 nails total

94x0.75= $70.50
He drove 178 miles in the afternoon. 248-70=178
The first thing to do is the make the denominators of the fractions the same.
5/10 of the pupils walked to school and 2/10 of the pupils came to school by bus.
5/10 + 2/10 = 7/10.
10/10 - 7/10 = 3/10.
<span>3/10 of the pupils came to school by car. </span>
The answer is 4,162 for 564+3,598
