John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

John multiplied the second equation by 4.

Step-by-step explanation:

We are given two linear equations and we know that John multiplied the first equation by -3 and the second equation by another number to eliminate the x-terms.

We are to find that another number.

4x-6y=2  --- (1)

3x+5y=11 --- (2)

Multiplying the first equation by -3 we get:

-12x + 18y = -6 --- (3)

Since we have to eliminate the x terms so coefficients of x must be the same with opposite signs. So we need 12x in the second equation to eliminate it.

For this, we need to multiply the second equation by 4 to get:

12x + 20y = 44

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
