1 answer:

7 0

Hey there!

Let's keep our goal in mind. We're looking fo a sum, which means a number plus a number, or the answer to that problem.

In order to simplify this, we need to use the distributive property which can be defined as:

a(b+c) = ab+ac

Now, we can use this forumula to express:

6(3+9) = 6(3) = 6(9) = 18 + 54 = 72

Hope this helps!

8. Find x

10x - 1 = 14x - 37 Combine like terms

+37 +37

10x + 36 = 14x Combine like terms

-10x -10x

36 = 4x Divide to isolate x

36 = 4x

4 4

9 = x

You can also do this method with the others.

PS: I am still not sure if this is the right method, lol. I just really want to help.

Which inequality represents the statement below?

Lubov Fominskaja [6]

The right answer is Option D: $x+\frac{5}{6}>\frac{14}{13}\\$

Step-by-step explanation:

Given;

A number increased by 5/6 is greater than 14/13.

Let,

x be the number.

When a number is increased, the amount is added in it, therefore,

x+ $\frac{5}{6}$

> is used for greater than.

Therefore, the inequality is

$x+\frac{5}{6}>\frac{14}{13}\\$

The right answer is Option D: $x+\frac{5}{6}>\frac{14}{13}\\$
