Answer:
9x/4= -9
Mutiply by 4 for both sides.
4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36
9x= -36
Divide by 9 for both sides
9x/9= -36/9
x= -4
Answer: 6x^3
Step-by-step explanation:
7/8(x-1/2)=-49/80
70/80(x-40/80)=-49/80 make all common denominator
x-40/80=-56/80 divide -49/80 by 70/80 to isolate parentheses
x=16/80 or 1/5 add 40/80 to isolate x
I'm not sure if my answer right because I was rushing but if you follow what I wrote next to the lines you should get the right answer
Turn 7/4 into a decimal by dividing it and then multiply from there and you get 1.75. Then you time 5.4 by 1.75 and you get 9.45
Answer:
1, 1:2 = 3:x
1/2 = 3/x.......(Criss cross)
x = 3x2/1 = 6 cups
2,. language arts : social studies
3,. 1/50 = 4.5/ x.....(Criss cross)
x = 50 x 4.5/1 = 225 miles
