After applying the linear combination method, Heather arrived at the equation 0 = 60. What conclusion can be drawn about the system of equations? The equation has no solution; therefore, the system of equations has no solution. The equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60). The equation has infinite solutions; therefore, the system of equation as infinite solutions. The equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).
Answer:
The correct answer is:
The equation has no solution; therefore, the system of equations has no solution.
Step-by-step explanation:
When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.

Find the product of 51 and -2.5.
Use the distributive property to rewrite and solve.
The first step is done for you.
51(-2.0) + 51(-0.5)
What is the next step in using the distributive property to solve this equation?
A) -102 + 25.5
B) 102 + (-25.5)
C) -102 + (-25.5)
D) -102 + (-25)
Answer:
A. -102 + 25.5.
Step-by-step explanation:
After multiplying 51 by -2.0, you will get -102. When multiplying 51 by -0.5, you get 25.5. A is the next step in this equation. (Optional answer: read this when this is also in your quiz. -102 + 25.5 = 127.5).

The bottom of a ladder must be placed 5 feet from a wall. The ladder is 18 feet long. How far above the ground does the ladder touch the wall?
Answer:
The ladder meets the wall at 17.29 feet from the ground.
Step-by-step explanation:
Pythagorean Theorem ⇒ a^2 + b^2 = c^2
5^2 + b^2 = 18^2
25 + b^2 = 324
b^2 = 299
b = 17.291616

Answer:
2.5x > 25
Step-by-step explanation:
1. 10 + 2.5x > 35
2. 10 + 2.5x - 10 > 35 - 10 (Subtracting 10 from both sides)
3. 2.5x +10 - 10 > 35 - 10 (Group like terms)
4. 2.5x > 35 - 10 (Simplify the arithmetic)
5. 2.5x > 25
Michael and Imani go out to eat for lunch.
Part A
If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill? Enter your answer to the nearest cent.
Part B
After adding a tip, the total lunch cost was $32.24. What percentage tip did they give? Enter your answer to the nearest percentage.
pls show how you set the problem up this is due soon so pls help!
Answer:
Given : Michael and Imani go out to eat for lunch.
their food and beverages cost $25.30
8% meals tax,
After adding a tip, the total lunch cost was $32.24
To Find : how much is the bill
What percentage tip did they give?
Solution:
food and beverages cost $25.30
8% meals tax,
Tax = (8/100) 25.3 = 2.02 $
BILL = 25.30 + 2.02
= 27.32 $
BILL = 27.32 $
After adding a tip, the total lunch cost was $32.24.
=> Tip = 32.24. - 27.32 = 4.92$
% of Tip = (4.92 / 27.32) * 100 = 18 %
Tip = 18 %
Step-by-step explanation:
Answer:
Part A: $28.46
Part B: 8.5%
Step-by-step explanation:
Part A:
We know that in this equation that 25.30 is the 100% number and we need to find 8% of this.
We can then divide 8 by 25.30 which is 3.1625 but the problem asks us to "round to the nearest cent" so we then know that the 8% is $3.16 we have to then add the 8% to the total which would be: 25.30 + 3.16 which equals $28.46 which is your answer to Part A.
Part B:
After adding a tip that problem states that the total went up from $28.46 to $32.24 to find out how much they tipped we can minus these 2 totals to find the difference
32.24 - 28.46 = 3.78
We now know that they tipped $3.78 and we now need to convert this into a percentage.
Right now the whole 100% is $32.24, we then divided 32.24 by 3.78 which would be 8.5291 and so on but wo round this it would be 8.5%
The answer to Part B would be 8.5%
help me it's algebra and dont tell me to look at the lesson :)
Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.
He's supposed to use a total of between 70 and 74 beads, so
70 ≤ b + g ≤ 74
The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so
1.4 ≤ g/b ≤ 1.6
For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions
b ≥ 0
g ≥ 0
(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y + 7 = (-14/17)(x - 8)
Step-by-step explanation:
We want the equation of this line in the point-slope form y - k = m(x - h).
We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:
Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:
7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17
The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).
Another way to get this result would be to find m in the usual way:
rise 14
m = ------------- = --------- = -14/17 (same as before).
run -17
how do i find x and y
Answer:
The x is the x-axis, which is a horizontal line. The y is the y-axis, which is a vertical line. The y-axis goes up or down, while the x-axis goes left or right.

Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.
Then you will get 40 degrees as your answer.
Hope This Helps :)

sterling plants a tree that is 4 3/4 feet tall. please do step by step!!!
Answer:
There's not really a question to answer there, you've only stated the information that we know. From what I can see the only conclusion I can make is that Sterling plants a tree that is 4 3/4 feet tall, but that's already written and with all the information provided that's really all I can say.
Sorry if that's not exactly what you were looking for, maybe if there's more to the question re-post it with the entire question?

when keisha installed a fence along the 200 feet perimeter of her rectangular back yard she left and opening for GATE in diagram below she used X to represent the length of the gate
Perimeter of her rectangular back yard is: 200 ft
⇒ 2(30 + 60 + x) = 200
⇒ 30 + 60 + x = 200/2 = 100
⇒ 90 + x = 100
⇒ x = 100 - 90 = 10
