Answer:

a and d are both true. The rest are not.

Step-by-step explanation:

1 and 6 are like terms. They are both integers. They can be combined. This statement is true.

7 is a numerical coefficent. This statement is true.

===========================================

The others are all false for one reason or another

b is false. The factor is made up of 2 terms not 3. 7a is one term.

c is false. "a" is a variable. So the whole term can be anything.

e is false. 7a + 2 is a factor

f is false. There are two true statements.

Hi, umm pls help 1/6(x-5)=1/2(x+6), solve for x And can you please explain

Mumz [18]

Answer:

By solving the equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ we found that $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$

Explanation:

Given equation,

$\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ to find x

Step: 1 Cross multiply the denominators 2(x-5)=6(x+6)

Step: 2 Open brackets and simplify the term 2x-10=6x+36

Step: 3 Bring x terms on one side and simplify the equation the equation obtained is following,

2x-6x=36+10

-4x=46

$-x=\frac{46}{4}=\frac{23}{2}=11 \frac{1}{2}$

Therefore, we solved x value from the given equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ as $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$ .
