-15 = 5a +12- 2a + 6 -11 -3 10 7
just olya [345]

Answer:

A

Step-by-step explanation:

So we have the equation:

-15=5a+12-2a+6

On the right combine like terms:

-15=5a-2a+12+6\\-15=3a+18

Subtract 18 from both sides. The right cancels:

(-15)-18=(3a+18)-18\\-33=3a

Divide both sides by 3:

(-33)/3=(3a)/3\\a=-11

The answer is A, -11.

On Thursday a local shop sold a combination of 417 hamburgers and cheese burgers. The number of cheeseburgers sold was two times
seropon [69]

Answer:

The number of hamburgers sold was 139 and the number of cheeseburgers  sold was 278.

Step-by-step explanation:

Let

x -----> the numbers of hamburgers sold on Thursday

y -----> the numbers of cheeseburgers sold on Thursday

we know that

x+y=417 ----> equation A

y=2x ----> equation B

Substitute the equation B in equation A and solve for x

x+2x=417

3x=417

x=139

Find the value of y

y=2(139)=278

therefore        

The number of hamburgers sold was 139 and the number of cheeseburgers  sold was 278.
