6 0

Answer:

a=7

Step-by-step explanation:

7(a – 10) = 13 – 2(2a + 3)

Open the bracket

7a-70=13-4a-6

Collect like terms

7a+4a=13-6+70

11a=77

divide both sides by 11

11a/11=77/11

a=77/11

a=7

Vilka [71]

Answer:

Number of cookies produced in 8 hour are 10,600 cookies.

Step-by-step explanation:
