Solve the equation -4(1.75 + x) = 18

Mathematics
1 answer:
Irina-Kira [14]2 years ago
3 0

Answer:

x= -25/4

Step-by-step explanation:

Simplify both sides of the equation:

-4(1.75+x)=18

(-4)(1.75)+ (-4)(x)=18 | Distribute

-7+-4x=18

-4x-7=18 | Then solve.

Add 7 to both sides:

-4x-7+7=18+7

-4x=25

Then divide both sides by -4

Answer:

The GCF is going to be 30

Step-by-step explanation:

This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 21, 2 × 3 × 3 × 5= 90

The prime factorization of 28, 2 × 3 × 5 × 7 = 210

The common factors are, 2, 3, and 5. We multiply those to get the GCF.

2 × 3 × 5 = 30

Find the missing value <br> 3/8 +1/?=5/8<br> 3/4-1/?=1/4<br> ?/6 + 1/8= 23/24
steposvetlana [31]
1st one : is 1/4 ( subtract 3/8 from both sides and simplify 5/8 - 3/8 to 1/4. )

2nd one : is 1/2 ( subtract 3/4 from both sides, simplify 1/4 - 3/4 to 1/-2, and then multiply both sides by -1 )

3rd one : is 5/6 ( subtract 1/8 from both sides and simplify 23/24 - 1/8 to 5/6).
