What is the best first step in solving -4x+ 10?

Mathematics
1 answer:
fredd [130]3 years ago
4 0

Answer:

Step-by-step explanation:

The first step is usually to isolate the x term. You have -4x - ⅖ on the lefthand side of the equation. You want to remove the -⅖ so the -4x is alone.

Add ⅖ to both sides:

-4x > ⅖ + 5/10

Length = l
width = 1/3 of length = l/3

perimeter = 2(l + l/3)
Answer is option B

-----------------------------------
2(l+ l/3) = 56
⇒ 8l/3 = 56
⇒ l = 3*56/8
⇒ l = 21 inch
width = 21/3 = 7inch

Area = 21*7 inch² = 147 inch²

Senior tickets (x)

Child tickets (y)

First day:  3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4   -4(3x + 5y = 70),  which makes it

-12x - 20y = -280

(+)12x + 12y = 216    add to second equation

-8y = -64

divide by -8.    y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8

Scott was considering the equation 5 – x = 12. He said, "That seems impossible. How can I start with 5 and subtract from it and
taurus [48]

Answer:

x = -7

Step-by-step explanation:

Given:

5 – x = 12

Subtract 5 from both sides

5 – x - 5 = 12 - 5

- x = 7

Note: the coefficient of -x is -1

- x = 7

Divide both sides by the coefficient of -x

- x / -1 = 7 / -1

x = -7

Check

5 – x = 12

5 - (-7) = 12

5 + 7 = 12

It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value
