Answer:
He is missing 1500, the final solution would be 2090
Step-by-step explanation:
5 times 8 equals 40
5 times 30 equals 150
50 times 8 equals 400
50 times 30 equals 1500
40+150+400+1500= 2090

the answer should be
Step-by-step explanation:
2nd step. ......-9+7=5x-x
3rd step............-2=4x
4th step.............-2/4=x
5th step.............-0.5=x
To solve this, you need to cross multiply the fractions.
Let’s say you have these fractions:
A / B = C / D
To cross multiply, multiply the denominator of the first fraction (B) by the numerator of the second fraction (C). Multiply the numerator of the first fraction (A) by the denominator of the second fraction (D).
You get B x C = A x D
After cross multiplying your fractions, you get 63 = 7(c +4)
Distributing the 7 into c+4 gives you this:
63 = 7c + 28
Now solve this like a normal equation with a variable
63 = 7c + 28
35 = 7c
5 = c
To double check that, plug c = 5 into the original equation.
1/(5) + 4 = 7/63
1/9 = 7/63
7/63 simplifies into 1/9 (7:7 = 1, 63/7 = 9)
1/9 = 1/9 so c = 5 is correct
