bill earns $40 more than half Ritas weekly pay. If their combined pay for a week is 520. what equation can we use to solve for r
itas weekly pay ?
1 answer:
X= Rita's pay
1/2x + 40= Bill's pay
x + (1/2x + 40)= $520
combine like terms
1 1/2x + 40= 520
convert to improper fraction
3/2x + 40= 520
subtract 40 from both sides
3/2x= 480
divide both sides by 3/2
x= 480 ÷ 3/2
to divide fractions, multiply by reciprocal of 3/2
x= 480 * 2/3
multiply numerators; multiply denominators
x= (480*2)/(1*3)
x= 960/3
x= $320 Rita's pay
ANSWER: Rita's pay is $320 using
x + (1/2x + 40)= 520.

Answer:
6 hours
Step-by-step explanation:
420 ÷ 70 = 6. Divide the distance and speed to get the amount of time.
Given inequality
=> −2(x+1)≥3x+8
=>
now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2

Answer:
x^2 -12x+36
Step-by-step explanation:
x^2 – 12x
Take the coefficient of x
-12
Divide by 2
-12/2 = 6
Square it
6^2 = 36
We need to add 36 to make x^2 -12x a perfect square trinomial
x^2 -12x+36
