Answer:
2
Step-by-step explanation:
First, you do the subtraction 120-21.4 which is 98.7. So since you know its x^7, the number isn't going to be big. By guessing and checking, we start with 2. 2^7 is 128. We know that 1^7 would just be 1, so the closest whole number would be two.
Answer: 14
Step-by-step explanation:
1.75x -2 + 1.75x -2 + 1.75x -2 =67.5
5.25x-6= 67.5
5.25x =73 .5
X = 14
X is 0, so it cancels out the 7. So then 3 divided by 30 is 10. Y=10.
