Answer:
Step-by-step explanation:
Okay this is an odd question, but what i'm thinking is that
first you have
5x+5
To actually be able to solve we have to move the 5 to the other side.
To do this we subtract it.
Making the equation
5x = -5
Then you need to isolate the variable (X)
So divide 5X by 5, and then divide -5/5
Which leaves you with:
x=-1
Answer:
x = 17
Step-by-step explanation:
A triangle's sum is 180 degrees, hence
6x + 10 + x + 17 + 4x - 34 = 180.
11x + 10 + 17 - 34 = 180
11x - 7 = 180
11x = 187
x = 17
hope this helps and is right!! p.s. i really need brainliest :)
Step-by-step explanation:
I got you,
a) Work...
First equation: y = 4x + 3
Second equation: y = 2x + 11
If he wants to play 2 games...
y = 4 (2) + 3
y = 11
y = 2 (2) + 11
y = 15
<u>Answer for part a: If a customer wants to rent shoes and play two games, they'll pay more with the new price plan. With the current price plan, they'll pay 11 dollars, but with the new price plan, they'll pay 15 dollars.</u>
b) Work...
seven games...
y = 4 (7) + 3
y = 31
y = 2 (7) + 11
y = 25
<u>Answer for part b: If the customer wants to play 7 games, including the shoes, they would pay less using the new plan. If the shes were not included, the new price will still be less. With the shoes, 7 games, with the original plan, is 31 dollars but 25 dollars with the new plan. If they didn't want to rent shoes, they would pay 28 dollars with the original plan but only 14 dollars with the new plan. All in all, they spend less on the new plan anyways.</u>
I hope this helps :)
Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100
He sold 100 rackets for $ 20
Answer:
She will deposit $17.
Step-by-step explanation:
So this is really simple.
20% of $85= 0.20•85= 17=$17
