Three times a number increased by 7 gives the same result as four times the number increased by 5? Heeellllpppp

Answers

If we were to write this as a mathematical equation, it would look something like this:

3x + 7 = 4x + 5

In order to solve, we would need to isolate the variable. We can do this by subtracting 3x from both sides, after doing which, we are left with this:

7 = x + 5

Then, we subract 5 from both sides to isolate the variable

2 = x

That number you are looking for is 2.

Let's check out work by substituting 2 in for the unknown number in the original problem:

3(2) + 7 = 4(2) + 5

6 + 7 = 8 + 5

13 = 13

And we can see that the numbers do indeed check out.

Your answer is 2.
Hope that helped! =)

Show your work:Use the distributive property in two different ways to find the product of 127 and 32.

Answers

The distributive property: a(b + c) = ab + ac

127 × 32 = 127 × (30 + 2) = 127 × 30 + 127 × 2 = (130 - 3) × 30 + (130 - 3) × 2

=(130)(30) - (3)(30) + (130)(2) - (3)(2) = 3900 - 90 + 260 - 6

= 3810 + 254 = 4064

127 × 32 = (130 - 3) × 32 = 130 × 32 - 3 × 32 = 130 × (30 + 2) - 96

= (130)(30) + (130)(2) - 96 = 3900 + 260 - (100 - 4) = 4160 - 100 + 4

= 4060 + 4 = 4064
