11
Step-by-step explanation:
2(x-1)+4(x+2)=72
2x-2+4x+8=72
6x+6=72
6x=72-6
6x=66
x=66÷6
x=11
Answer: 2 + 2 x 10 = 22
10 x 100 (?) = 1,000
1,000 x 10,000 (?) = 10,000,000
Step-by-step explanation:
For A, (2 + 2 x 10), you need to multiply first, 2 x 10 = 20. Then, you must add 2, which equals 22.
For B, which is (10 x 100, I think) you will multiply the top number by the bottom number, let’s say 100 is on the top. You will line thin up, 100 x 10. You will need to multiply 0 times 100, which is 000. You will then need to move over a slot, and then times 100 by 1. After doing that then you add your numbers, which gives you 1,000.
For C you do the same steps you used for B.
