Answer:
x=1 and y= 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
To solve this, lets take the first equation and find the x value.
Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.
5x+4y=16
-5x -5x
4y=-5x+16
÷4 ÷4 ÷4
y=[tex]\frac{-5}{4}[/tex]+4
or
y=-1[tex]\frac{1}{4}[/tex]+4
or
y= 5[tex]\frac{1}{4}[/tex]
Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:
5x+4([tex]\frac{-5}{4}[/tex]+4)=16
5x-5+16=16
5x+11=16
-11 -11
5x=5
÷5 ÷5
x=1 and y= 5[tex]\frac{1}{4}[/tex]

Charlie is thinking about buying a game for his Xbox that cost $60 and requires a subscription to basic Xbox live that cost $10 per month he could choose to upgrade his Xbox live membership and then the game will be included but that membership is $15 a month how many months would Charlie have the game before the cost of the two is the same?
Answer:
by 12 months both prices will be 180.
Step-by-step explanation:
If you take 12 and multiply it by 10 because that is the monthly subscription, you will get 120 + 60 for the game which equals 180. But if you take 12 and multiply it by 15 you will also get 180.
Hope this helps

Solve this equation for x:
-100+2х=80+бх
Answer:
-45
Step-by-step explanation:
-100 + -80 = 6x + -2x
-180 = 4x
-180/4 = -45
Answer:
x= -45
Step-by-step explanation:
-100 + 2x = 80 + 6x
-80 - 2x = -80 -2x
------------------------------
-180 + 0 = 0 + 4x
-180/4 = x
-45 = x

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH
Answer:
3/4 of the pot left.
Step-by-step explanation:
If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
Answer:
3/4 of the pot is left over
Step-by-step explanation:
find the least common denominator- in this case 121/12 and 2/12= 3/123/12-12/12=9/129/12=3/4 by simplfyingWhat is the highest common factor of 72 and 90

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.
Answer:
d
Step-by-step explanation:
The volume of the triangular prism.
= Base area x length of the prism
The volume of the rectangular block.
= Length x width x height
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.
What is a rectangle?
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Module house:
Triangular prism on top and a rectangular block.
The volume of the triangular prism.
= Base area x length of the prism
= (1/2 x 12 x 4) x 15
= 24 x 15
= 360 cubic feet
The volume of the rectangular block.
= Length x width x height
= 12 x 15 x 5
= 900 cubic feet
The volume of the block house.
= Volume of the triangular prism + Volume of the rectangular block
= 360 + 900
= 1260 cubic feet
Thus,
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.

Answer:
(-3, -5)
Step-by-step explanation:
We will multiply (6a -2b = -8) by -3, and (a - 3b = 12) by 2
Thus,
-18a + 6b = 24
2a - 6b = 24
=
-16a = 48
a= -3
Then we'll substitute,
-18(-3) + 6b = 24
54 + 6b = 24
6b = -30
b = -5
