To solve this question, we can start to set up an equation using what the question is telling us. Since we don't know what the number is, let's make it equal to x.

The phrase "5 times a number" means that we're multiplying our unknown, x, by 5. That is equal to 5x. 9 less than that would be 5x - 9. Since we know that it's equal to -30, we can solve.

5x - 9 = -30

Get all terms with x on one side and the constants on the other

5x - 9 +9 = -30 + 9

Simplify

5x = -21

Now, we can divide both sides by 5 to get our answer of x = - $\frac{21}{5}$

Hi, I’m really struggling, if anyone knows, please could you help?

pshichka [43]

Answer: a) 26

Step-by-step explanation:

-a would be because as you can see there is a pattern of sticks, so what i did was count up the sticks and i found that there was 6 in the first one. So i counted the second one and it was 10 so i realized that all i had to do was add 4.

and for b i think when it says n it means the nth term which is 4 so i think it means pattern 4 which would be 18 so try that out

hope this helped x

Which equation represents "the product of a number and 24 is 72"?

sattari [20]

24 x O = 72

You’re looking for an equation where 24 is multiplied by a number to equal 72, so put 72 on one side of the question and multiply 24 by a variable on the other.
