Answers

Answer 1

Answer:

The number should be multiply is 10.

What is multiplication?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.

Given:

n=0.9

Now, there is one number behind decimal point.

So, we have to multiply it by 10 to convert it into fraction from decimal.

Thus,

10n = 0.9*10

10n = 9

n = 9/10

Hence, the number must be multiplied is 10

Answers

Answer:

x = .58

Step-by-step explanation:

-13=7d+64 what is the answer

Answers

Step 1: move 64 to a left side, -13 - 64 = 7d

Step 2: -77 = 7d

Step 3: $(-77)/(7)$ = d

Step 4: d = -11

it is d=11
because u subtract the negative 64 with a positive for a positive and negative turn 0 then u got to do the same side with -13-(-64)=7d then u add -13+-64=77 after u done that it will be 77=7d divide it by 7 on both side then u get d=11
