560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
There are a couple of things about this question that bother me.
1). BOB11111111 copied the question but didn't take the time to give us
the picture that goes with it. That bothers me.
2). If ABC is a triangle, then ABC cannot be a line. That also bothers me.
As it is, there's no way for anyone to answer the question without more
information than what we have here.
Answer:
345
Step-by-step explanation:
We can solve this problem by two equations. Our variables will be the following:
is the amount to be multiplied
and
is the amount that should be obtained by multiplying by 43
Thus our <u>first equation</u> is:

But the problem tells us that there was an error and the number
was multiplied by 34, so the result failed by 3105, thus the <u>second equation</u> is as follows:

By multiplying the quantity by 34, an amount is obtained that differs from 3105 from what it would have been obtained if multiplied by 43.
Now we are going to <u>replace the first equation in the second one </u>(
):

And clear to find x:

The number that jimmy was supposed to multiply by 43 is 345.
