Last month Albert earned half of what Betty earned, while Betty earned $5000 more than what Calvin earned. If Donna earned twice what Calvin earned and Albert and Betty together earned $900 more than what Calvin and Donna earned together, how much did each person earn?
Answer:
Calving earning = 4400
Betty earning = 9400
Albert earning = 4700
Donna = 8800
Step-by-step explanation:
Given that :
Calving earning = c
Betty earning = c + 5000
Albert earning = (c + 5000) /2
Donna = 2c
c + 5000 + (c + 5000) /2 = 900 + c + 2c
c + 5000 + 0.5c + 2500 = 900 + 3c
1.5c + 7500 = 900 + 3c
7500 - 900 = 3c - 1.5c
6600 = 1.5c
c = 6600 / 1.5
c = 4400
Calving earning = c = 4400
Betty earning = 4400 + 5000 = 9400
Albert earning = (4400 + 5000) /2 = 4700
Donna = 2(4400) = 8800
2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2
Hannah factored the expression 24xy + 15y. Her work is shown below.
1. GCF (24xy, 15y) = 3y
2. 24xy/3 = 8xy, 15y/3 = 5y
3. 3(24xy + 15y)
What are the errors in Hannah’s work? Check all that apply.
She divided by 3 instead of the GCF.
She found the wrong GCF.
She divided wrongly.
She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.
She didn’t undistribute the GCF from the original expression.
Answer:
The correct answers for the multiple choice question are:
Option 1 (or A): She divided by 3 instead of the GCF.
Option 4 (or D): She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.
Option 5 (or E): She didn’t undistribute the GCF from the original expression.
Step-by-step explanation:
I got it correct on Edge.
The errors in Hannah’s work are she divided by 3 instead of the GCF and she didn’t undistributed the GCF from the original expression.
The given expression is 24xy+15y.
Here, the factors of 24xy are
24xy = 2×2×2×3×x×y
15y = 3×5×y
So, common factors from both the terms is 3y.
Now, divide and multiply the given expression by 3y.
3y(24xy/3y + 15y/3y)
= 3y(8x+5)
Therefore, the errors in Hannah’s work are she divided by 3 instead of the GCF and she didn’t undistributed the GCF from the original expression.
