Answer:
Step-by-step explanation:
If you have two equations for y, eliminate y by setting these two equations equal to one another. Solve the resulting equation for x. Then substitute your x value into one of the equations for y. Write your solution as (x, y).
2) If you need to solve for a variable to substitute, what is your first step? Example: If you have two equations for y, eliminate y by setting the two equations equal to each other. This decides for you that you must solve for x.
3) What does it mean to substitute for a value? Example: If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x. This eliminates y and allows you to solve for x.

What is 2+4+6-9+17-4=x
Answer:
x = 16 or 16 = x
Step-by-step explanation:
2+4+6-9+17-4=x
6+6-9+17-4=x
12+17-9-4=x
29-9-4=x
20-4=x
16=x
Answer:
[tex]x = 16[/tex]
Step-by-step explanation:
[tex]2 + 4 + 6 = 12[/tex]
[tex]12 - 9 = 3[/tex]

Which is the better deal: $4.47 for 3 liters or $7.25 for 5 liters? Explain why.
Answer:
$7.25 for 5 liters
Step-by-step explanation:
If you get the unit rate of $4.47 for 3 liters it is 1.49 per liter.
1.49 x 5 = 7.45
Therefore, $7.25 for 5 liters is a better deal than $7.45 for 5 liters.

The product of 45 and the counting number n is a perfect cube. find the least possible value for n.
PLS HELP.
The counting number n is 75 which when multiplied with 45 gives perfect cube.
What is a perfect cube?Numbers which are the triple product of the exact number are known as perfect cubes.
In other words, we can say the value produced by multiplying a whole number by three times itself is a perfect cube.
A number that may be expressed as three times the product of another integer is also termed as a perfect cube.
It is given in the question that the product of 45 and the counting number n is a perfect cube
So, we have to find the counting number n
First of all we will factorise 45
45 = 5 × 9
After factorising we get,
45 = 3×3×5
For 45 to become perfect cube we have to multiply the factors with 3×5²
45 = 3×3×3×5×5×5
∴ 3×5² = 75
Hence , the counting number n is 75 which when multiplied with 45 gives perfect cube.

How can I add ¾? Explain.
Answer:
Step-by-step explanation:
you can do many things to add 3/4, most common way si thinking of 3/4 3 quarters of your number
you can add 3/4 to 1 which is 1 3/4
1+3/4=1 3/4
or,
you could do
3/4 OF 10 is 3 quarters of 10 which is 2.5x3 or 10 -2.5 which equals,
7.5
Answer:
You can add 3/4 by adding as a decimal so 3/4 of 100 is 75 so it would be .75

I DONNT UNDDERSTAND THIS AT ALL
Answer:
Here's exactly what I would write:
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies, d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
a = 4d
b = 3e
c = 2f
Expression for Sandy: 4d + 3e + 2f
Expression for Sandy and Nina: 5d + 4e + 2f
Step-by-step explanation:
This is a terrible question that makes people feel frustrated. I'm sorry.
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies,
d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
Sandy has 4 times the number of cupcakes as Nina: a = 4d
Sandy has 3 times the number of gummy bears as Nina: b = 3e
Sandy has 2 times the number of brownies as Nina: c = 2f
An expression for how many desserts Sandy is bringing: a + b + c
An expression that could be used for how many desserts Sandy and Nina are bringing together: a + b + c + d + e + f, but I think they want you to substitute the equivalent values like above (a = 4d)
Sandy: 4d + 3e + 2f
Sandy and Nina: 5d + 4e + 2f
because 4d + 3e + 2f + d + e + f = 5d + 4e + 2f
I'm sorry I don't have a simpler way to explain this. It's a painful question. I will answer any questions you have.

[tex]\Huge\boxed{x=29}[/tex]
Step-by-step explanation:
Hello There!
Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180
so we use this equation to solve for x
180 = x + 4x + 35
step 1 combine like terms
x + 4x = 5x
now we have 180=5x+35
step 2 subtract 35 from each side
180 - 35 = 145
35 -35 cancels out
now we have 145 = 5x
step 3 divide each side by 5
5x/5=x
145/5=29
we're left with x = 29
Answer:
(×+35)+4×=180°[sum of angles in a str. line ]
5×=180-35
5×=145
5x/5=145/5
x=29

9514 1404 393
Answer:
2709.7 square inches
Step-by-step explanation:
If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.
larger area = 49(55.3 in^2) = 2709.7 in^2

Harper only has $15 to spend at the grocery store. She buys Doritos that cost $2 per bag and one sandwich for $8. Which solution set would represent the options for the number of bags of Doritos she can buy.
Answer:
2x + 8 ≤ 15
Step-by-step explanation:
Hi,
2x represents the cost for each bag of doritios. The 8 is the cost of the sandwitch. And 15 is how much money she can spend :)
Answer:
2d + 8 ≤ 15
Step-by-step explanation:
Let the amount of Doritos bags be represented by d.
2d + 8 ≤ 15
With this, we can solve.
2(3) + 8 ≤ 15
6 + 8 ≤ 15
14 ≤ 15
The equation is true, and we cannot go any further.
The answer is ≤ 3.
Hope this helps. Have a nice day.
