Answer:
(2,1)
Step-by-step explanation:
multiply by negative three on the first equation then solve
Answer:
(-2, 1)
Step-by-step explanation:
Given:
2x+8y=4...(1)
6x-y=-13...(2)
You would want to have an x or a y value that equals the same in both equations. In this case, we can multiply equation 1 by 3 so that both x's in each equation equal 6x.
(2x+8y=4) x 3...(1)
6x-y=-13...(2)
becomes...
6x+24y=12...(3)
6x-y=-13...(4)
As you can see here, both x's in this equation are equal.
Now we will be combining these equations together. Take the equal x values and make sure they will equal 0. You do that by either subtracting the entire equation or adding it. In this problem, we will be subtracting it because 6x-6x=0
(6x+24y=12) - (6x-y=-13) = 25y =25
Now that we can solve for y separately, 25y=25 y=1
To solve for x, just substitute y into one of the original equations (equations 1 or 2). For this problem, I'll use equation 1.
6x-y=-13
6x-1=-13
6x=-12
x=-2

Solve for y: 8x - 3y = 17
Option 1: y = -3/8 x - 17/3
Option 2: y = 8/3 x - 17/3
Option 3: y = -8/3 x + 17/3
Option 4: y = 3/8 x + 3/17

Answer:
x = 2.125 + 0.375y
Step-by-step explanation:
Simplifying
8x + -3y = 17
Solving
8x + -3y = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
8x + -3y + 3y = 17 + 3y
Combine like terms: -3y + 3y = 0
8x + 0 = 17 + 3y
8x = 17 + 3y
Divide each side by '8'.
x = 2.125 + 0.375y
Simplifying
x = 2.125 + 0.375y
Simplify the expression.

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube
Answer:
The measured side is not shown, so i will answer in a general way.
A cube is a 3-dimensional object with 6 square faces.
You know that all the sides of a square have the same length, then is the same for the cube.
To calculate the volume of a cube, we start with the area of the base.
The base is a square of sidelength L (Suppose that L is the length of the measured side)
The area of the base is:
A = L^2.
To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).
And the height of the cube is also L.
Then the volume is:
V = L*a = L^3

To make 3/4 pound it makes nuts how many pounds of cashews would you add to 1/8 pound them almonds and 1/4 pound of peanuts
9514 1404 393
Answer:
a. 3/8 lb of cashews
Step-by-step explanation:
The amount that needs to be added is the difference between the amount of mix wanted and the amount of mix provided by the given quantities of nuts.
3/4 lb - (1/8 lb +1/4 lb) = (3/4 -1/4 -1/8) lb = (2/4 -1/8) lb = (4/8 -1/8) lb
= 3/8 lb . . . . amount of cashews needed

Put the following equation of a line into slope intercept form, simplifying fractions
Answer:
y = - [tex]\frac{1}{5}[/tex] x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 20y = - 180 ( subtract 4x from both sides )
20y = - 4x - 180 ( divide all terms by 20 )
y = [tex]\frac{-4}{20}[/tex] - [tex]\frac{180}{20}[/tex] , that is
y = - [tex]\frac{1}{5}[/tex] x - 9 ← in slope- intercept form
What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerator and the denominator for the first fraction b) change the places of the numbers in the numerator and the denominator for the second fraction c) change the places of the numbers in the numerator and the denominator for both fractions d) change the ÷ between the fractions
Answer:
b) change the places of the numbers in the numerator and the denominator for the second fraction
Step-by-step explanation:
In the phrase "keep change flip":
You "keep" the first fraction.
"Change" the division sign into a multiplication sign.
"Flip" (or switch) the places of the numerator and denominator in the second fraction.
Example:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

1. The ratio of boys to girls in the 9th grade is 3 to 4. There are 176 girls. Set up a proportion to model this information.
Answer:132
Step-by-step explanation:
Write the four terms of the sequence f(n) = 12 + 3(n-1)
9,12,15,18,21
12,15,18,21,24
-12,-9,-6,-3,0
Explanation:
The given arithmetic sequence is of the form
a+d(n-1)
where 'a' is the first term and d is the common difference
In the case of
12+3(n-1)
we have a = 12 as our first term and d = 3 as the common difference. This means we start with 12 and add on 3 to each term to get the next one
12+3 = 15
15+3 = 18
18+3 = 21
21+3 = 24
and so on.
Side note: your teacher asks about the first four terms, but each answer choice lists five terms.

Step-by-step explanation:
The sugar sweet company is going to transfer its sugar to market. It will cost $4500 to rent trucks, and it will cost an additional $225 for each ton of sugar transported.
Let C Represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this equation to find a total cost to transport 14 tons of sugar.
Answer:
C=$7650
Step-by-step explanation:
Flat fee of 4500
S= 225x
x=14 tons of sugar
4500+225(14)=$7650 (C)
Equation:
C=4500+225(S)
Answer:
Total cost to transport 14 tons of sugar: $7650
Step-by-step explanation:
In the problem we are trying to find, C, the total cost to transport 14 tons of sugar.
$4500 to rent trucks
Additional $225 for each ton of sugar transported
C=4500+225(S)
We have our equation so now when begin to solve.
The problem gives us, S, the number of tons of sugar we are transporting, which is 14 tons.
So if it is an additional $225 for each ton of sugar then we would multiply 225 and 14. Which will look something like this:
C=4500+225(14)
Now we just simplify!
225(14)=3150
C=4500+3150
C=7650
