Answer:
7. 37
8. 74
9. 402
10. 74
Step-by-step explanation:
You can simplify the expressions and then do the substitution of the variable value, or you can simply plug in the numbers and do the arithmetic. Either way takes about the same effort.
7. 3(5·4 -1) -4(3·4 -7) = 3·19 -4·5 = 57 -20 = 37
8. 3(5·4 -6) +4(20 -3·4) = 3·14 +4·8 = 74
9. 5(10r +3) -7r = 50r +15 -7r = 43r +15 = 43·9 +15 = 402
10. 4(5r -3) -2(6r -7) = 20r -12 -12r +14 = 8r +2 = 8·9 +2 = 74

Ants, butterflies, beetles
Just look for the smallest number out of the three and then the smallest out of the two left, like 10,2,20. 2, 10, 20
