1 x14=14 * what times one is one*
2 x7=14
2x+2y=38
y=x+3
First you would substitute the y for x+3
2x+2(x+3)=38
You would multiply the 2 by the x+3
2x+2x+6=38
Add the 2x and the 2x
4x+6=38
Subtract the 6 on both sides
4x=32
Divide the 4 on both sides
x=8
Now substitute the x in the second problum for 8
y=8+3
Add the 8 and the 3 to solve for y
y=11
Your answers
x=8
y=11
the correct answer would be A:(8,11)
0.732
0.750
If you have trouble with decimals, then multiply both numbers by a constant number to get rid of the decimals. In this case, we would multiply by 1000.
0.732 x 1000 = 732
0.750 x 1000 = 750
Obviously, 750 is bigger than 732. Therefore, 0.75 is bigger than 7.32.
By the way, this is a property:
