The like terms are 5x and 3x because they both are apart of the x family !

I need help with this, please

Mamont248 [21]

Answer:

x = 1.5

Step-by-step explanation:

First, we distribute (get rid of parentheses):

6x - 3 - 3x = 5 - x - 2

Then, we simplify:

3x - 3 = 3 - x

Then, we combine like terms:

3x + x = 3 + 3

Then, we simplify again:

4x + 6

Finally, we divide 4 on both sides:

We got x = 1.5

Hope this helps!

Hey yall, 20 points? Factor to write an equivalent expression: 26a−10

Oksanka [162]

Answer:

2 (13a -5)

Step-by-step explanation:

Work Shown:

The GCF of 26 and 10 is 2. This is the largest factor that goes into both.

26a = 2*13a

10 = 2*5

So,

26a - 10 = 2*13a - 2*5 = 2(13a-5)

I'm using the distributive property to factor the 2 out.

Solve the system of equations using substitution: 7y+2x=16 5y-9=x

7nadin3 [17]

7y+2(5y-9)=16
7y+10y-18=16
17y=34
y=2

5(2)-9=x
10-9=x
x=1

-17 < 3 - 5x Idek anymore

zubka84 [21]

Step-by-step explanation:

-17 < 3 - 5x

-3 -3 step 1: subtract 3 from both sides

-20 < -5x

/-5 /-5 step 2: divide both sides by 5

4 < x

What is the lmc of two numbers that have no common factors greater then 1

Luba_88 [7]

We can take prime numbers so they don't have a common factor other than 1.

3, and 5.

So we have to list the multiples to find the LCM

3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20, 25

15 is the LCM of 3 and 5

So, you can notice that if two numbers, lets call them a and b, have no common factor, then $a \times b$ is the LCM.

Hope that helped :)
