Multiply 4 times 4 times 18 times 8. Then you should get your answer. May need to use and calculator.
D because D as a non-fraction is 6.8
Answer:
its equal
Step-by-step explanation:
15 times 5 (a) is 75 soooo 75 is equal to 75 maybe
1.2a+1.15b=(680+118)=798 and a+b=680,
Solving for a from the second equation we get: a=680-b
Using 680-b for a in the first equation we get:
1.2(680-b)+1.15b=798
816-1.2b+1.15b=798
816-0.05b=798
-0.05b=-18
b=360, and since a=680-b
a=320
So the a team was supposed to produce 320 parts and the b team was supposed to produce 360 parts...
check...
320*1.2+360*1.15=680+118
384+414=798
798=798
The answer would be(-4,8)...i think☺
