70 + 7 = 77
70
70
If you mean: 3+5x+7 = 70 then the value of x is 12
To write 7000 plus 700 plus 70 plus 7 in standard form, you simply combine the values. This results in 7000 + 700 + 70 + 7 = 7777. In standard form, you would express this number as 7.777 × 10^3.
Well, 10% of 70 would be 7. So if I am understanding the question correctly, I would have70+(10% of 70) -> 70+(.1*70) -> 70+(7)70+7=77
The first clue here is to try and write this with mathematical symbols. plus is +, and "the same as" is equal. So this would sound "What does 200 + 70 + 7 equal?", which could further translate into: 200+70+7 = ? The answer: 277
105/70 + 45/70 + 49/70 = 199/70 or 2 and 59/70
1/10 + 2/7 = 7/70 + 20/70 = 27/70

Write them out in numbers and add them: 7 millions = 7 x 1000000 = 7000000 7 tens = 7 x 10 = 70 7 ones = 7 x 1 = 7 7000000 + 70 + 7 = 7000077
