Answer:

Replace the y value in y=7x+3 with 9x

Answer: x=3/2

Step-by-step explanation:

y=7x+3; y=9x

9x=7x+3

Subtract 7x from both sides

2x=3

Divide by 2 on both sides

x=3/2

((3^3 - 7) • 5)/10 + ((1+3+6+9)-10)
jasenka [17]

Answer:

19

Step-by-step explanation:

(33−7)(5)/10+1+3+6+9−10

= (27−7)(5)/10+1+3+6+9−10

= (20)(5)/10+1+3+6+9−10

= 100/10+1+3+6+9−10

=10+1+3+6+9−10

=10+4+6+9−10

=10+10+9−10

=10+19−10

=10+9

=19

(+2) + (-2) = 0
FromTheMoon [43]

Hi there !!

The sum of two numbers is the number obtained by adding two given numbers. However, the opposite numbers are two numbers whose sum is equal to 0.

Example : (+3) + (-3) = 0

The answer is :

(+2) + (-2) = 0 because (-2) is the additive inverse of (+2).
