17 = − 13 − 8 x

Show your steps Please :3

Answers

Answer:

x = 3.75 or [tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

17 = -13 - 8x

add 13 to both sides

17 + 13 = -13 + 13 + 8x

30 = 8x

divide both sides by 8

30/8 = 8x /8

3.75 = x

Add 13 on both sides to get the x and it’s coefficient together. Now it is 30 = -8x. Divide both sides by negative 8 and X is equal to 3.75.

Write an equation that you can use to find the number of refills Keith bought. A restaurant sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Keith spent $31.75 on a mug and refills. (use x for your variable and do not use $ in your answer) *

Answers

Answer:

6.75+1.25x=31.75

Step-by-step explanation:  

let x be the number of refils

also given is that the cost of one refill is $1.25

hence the total refil will be 1.25x

given that the cost of a mug is $6.75

6.75+1.25x=31.75

therefore  the expression that can be used to solve for the number of refills is

6.75+1.25x=31.75

Convert 0.04 to a fraction in lowest terms. *

Answers

Answer:

1/25

Step-by-step explanation:

0.04 = 4/100 = 1/25

Answer:

[tex]\frac{1}{25}[/tex]

Step-by-step explanation:

0.04 is equal to [tex]\frac{4}{100}[/tex]. You can simplify this when both the numerator (the top number of the fraction) and the denominator (the bottom number of the fraction) can be divided by the same number. In this case, both numbers can be divided by 4, which would simplify it to its lowest form: [tex]\frac{1}{25}[/tex].

Hope this helps.
