Answer:
4. 61
5. approximately 43
6. 120
Step-by-step explanation:
4. 80 + 39 = 119
180 - 119 = 61
5. 7x - 10 = 90
+10 +10
7x = 100
divide by 7
x = 14.3
3 times 14.3 = 42.9
6. 70 + 50 = 120
180 - 120 = 60
180 - 60 = 120
x=15
divide 12/20 by 4 to get 3/5 then multiply by 3 to get your value of x
it would be A or D for the math of d=-2
y e s , m e h f r i e n d
