2x-5+7y-3=9x-1-y-8
2x+7y-8=9x-y-9
2x-9x-8+9=-y-7y
-7x+1=-8y
-7x=-8y-1
7x=8y+1
x=8y+1/7

Answer:

$\large\boxed{\sf x = \frac{8y+1}{7} }$

$\large\boxed{\sf x = \frac{7x-1}{8} }$

Group the Variable's:

2 x - 5 + 7 y - 3 = 9 x - 1 - y -8

2x -9x + 7y +y = -1 -8 +5 + 3

-7x + 8y = -1

From this find x and y

For X

-7x + 8y = -1

-7x = -1 -8y

7x = 8y + 1

x = (8y +1)/7

For Y

-7x + 8y = -1

8y = -1 +7x

y = (7x -1)/8

the amount y of your friends allowances if the amount she receives is 2$ more than the amount x you receive

liberstina [14]

Hello, How are you doing today?

If your friend makes 2$ more than you do, then you must form an equation for the problem. y = amount she has, x = your amount. Therefor, it would be:

y = x + 2

If you make 6 dollars, she will make 8 and so on. Thank you, have a nice day!

Bryan’s monthly electric bill is determined by adding a flat administration fee to the product of the number of kilowatt hours o

Sophie [7]

We will form the equations for this problem:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
z = ? Monthly administration fee is notated with z, and that is the this problem's question.
Number of kilowatt hours of electricity used are numbers 1100 and 1500 respectively.
Cost per kilowatt hour is notated with y, but its value is not asked in this math problem, but we can calculate it anyway.
The problem becomes two equations with two unknowns, it is a system, and can be solved with method of replacement:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
----------------------------
(1) z = 113 - 1100*y [insert value of z (right side) into (2) equation instead of z]:
(2) 1500*y + (113 - 1100*y) = 153
-------------------------------------------------
(1) z = 113 - 1100*y
(2) 1500*y + 113 - 1100*y = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y + 113 = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 153 - 113
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 40
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 40/400
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 1/10
------------------------------------------------
if we insert the obtained value of y into (1) equation, we get the value of z:
(1) z = 113 - 1100*(1/10)
(1) z = 113 - 110
(1) z = 3 dollars is the monthly fee.

Can someone please help me with these 3, 7th grade math homework word problems. I will give brainliest and obviously a thanks

NikAS [45]

Answer:

Mia can spend no more than $55 at the mall. She buys a jacket for $23. Necklaces are on sale for $8. Find the amount of necklaces Mia can buy. Write and solve an inequality.

First, make the equation. She can't waste no more than(≥ or =) $55. And she already used $23.

55= 23+8(n)

n= number of necklaces she can buy.

Now, subtract 23 to both sides.

55= 23+8(n)

-23 -23

32= 8(n)

Then, divide by 8 to both sides to find how many necklaces she can buy.

32= 8(n)

8 8

4=n So, she can buy 4 necklaces.

A bag of marbles contains 3 red, 5 blue and 2 yellow marbles. What is the probability of choosing a blue marble and then choosing a red marble without replacement. Simplify the fraction.

First, add up the whole amount of marbles.

3+5+2= 10

This is very simple, to find the probability, just put...

number of blue marbles

total number of marbles

This gives you, 5/10 and simplified into 1/2.

For the red marble, do the same thing.

number of red marbles

total number of marbles

This gives you, 3/10 and it can't be simplified.

A football team loses 5 2/3 yards on the first play. On the next play, they gain 2 3/4 yards. What is the overall increases or decreases in yards?

For this word problem, add 2 3/4 yards to 5 2/3 yards to find the overall decrease or increase in yards.

Solve the whole number parts..

5-2= 3

Solving the fractions part...

2 - 3 = 8 - 9 = - 1

3 4 12 12 12

3- 1/12= 2 11/12

So, it was a 2 11/12 decrease.
