Laura is bowling 5 games. Her first 4 scores were 118, 128, 124, and 98. To end up with an average score of at least 123.2, what
BartSMP [9]

Answer:

148

Step-by-step explanation:

Average = sum of numbers /total numbers

let x = 5th number

123.2 = (118+ 128 + 124,+ 98 + x) / 5

123.2 = (468 + x) / 5

Multiply both sides by 5

616 = 468 + x

x = 148

Three ordered pairs that solve the equation x - 4 Y equals -18
lawyer [7]
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18

when y=1, x=-16
when y=0, x=-18
when y=2, x=-10

(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)

Domain of the equation: 3(6y+21)!=0

y∈R

We add all the numbers together, and all the variables

4/3(6y+21)-60=0

You multiply all the terms by the denominator

-60*3(6y+21)+4=0
