Step-by-step explanation:
multiplying the 2nd eqn by 9 we get,
9x+9y=81
then,subtracting 1st and 2nd eqn
9x+5y=41
9x+9y=81
- - -
__________
0. -4y=-40
we get y = 10
then we get x=9-y
x=9-10
x= -1
so x is -1 and y is 10
Answer:
-100
Step-by-step explanation:
1/5 of -125 will be -25.
So, if she deposits 1/5 of what she owes, then she will deposit $25.
Her balance will then become -100 because she paid back 25.
Her new balance is -100
Answer:
In this case we can propose a rule of three:
$ 18 ---------------> 100%
x --------------------> 25%
Where x represents the discount made to the pillow:
So we have the new price (with the discount) is:
In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the number be x
1 2/3% of x = 4.75
5/3% of x = 4.75
5/(3×100) × x = 4.75
5x/300 = 4.75
5x = 300×4.75
5x = 1425
x = 1425/5
x = 285
Answer:
After discount: $829.49. Savings is $355.50
Step-by-step explanation:
We are going to use a GE Dishwasher. The price listed is: $1184.99. If you had a 30% off coupon, The price after the discount is: $829.49. You would save $355.50
Multiply 1184.99 by .30 this will give you savings
Next subtract the savings 1184.99 - 355.50= 829.49.
