I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell?
Answers
c - cookies
m - muffins
c + m = 27
3c + 7m = 129
I don’t know how to explain how to do efficiently but I just plugged in numbers until it worked:
3(15) + 7(12) = 129
45 + 84 = 129
Answer:
You sold 15 cookies and 12 muffins
Step-by-step explanation:
So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7
You're also given that in total you made $129, and sold 27 items
Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.
3c + 7m = 129 (equation for amount of money made)c + m = 27 (equation for amount of items sold)Now we can use the second equation to find m:
c + m = 27
m = 27 - c
Not we can substitute m into the first equation to find c:
3c + 7m = 129
3c + 7(27-c) = 129 [substitute m for (27-c)]
3c + 189 -7c = 129 [distribute 7 into (27-c)]
-4c + 189 = 129 [combine like terms]
-4c = -60 [subtract 189 from both sides]
c = 15 [divide both sides by -4]
Now we can substitute c into the second equation to find m:
c + m = 27
15 + m = 27
m = 12

Which system of equations is satisfied by the solution shown in the graph?
Answers
Answer:
(-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.
Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.
Step-by-step explanation:
We know that the point of intersection of two lines on a graph is the solution of the system of equations.
From the graph, it is clear that the two lines intersect at x=-2 and y=8.
Thus, the point of intersection of the two lines is (-2, 8)
Putting the (-2, 8) in the first system of equations
x+2y=10 and x-y = 6
-2+2(8)=10 and -2-8=6
14 = 10 and -10 = 6
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=10 and x-y = 6.
Putting the (-2, 8) in the second system of equations
x+2y=6 and x-y = 10
-2+2(8)=6 and -2-8=10
14 = 6 and -10 = 10
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=6 and x-y = 10.
Putting the (-2, 8) in the third system of equations
x+y=6 and x-y = 10
-2+8=6 and -2-8=10
6 = 6 and -10 = 10
L.H.S = R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of x-y = 10 is not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-y = 10.
Putting the (-2, 8) in the second system of equations
x+y=6 and x-2y = 10
-2+8=6 and -2-2(8)=10
14 = 6 and -18 = 10
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-2y = 10.
In a nutshell, (-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.
Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.

All five terms of GP are 500, 800, 1280, 2048, and 3276.8.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
Given the first term 500
And it is growing by 0.6 factor
It means,
Second term = first term + 0.6 of first term
Second term = 500 + 0.6(500)
Second term = 500 + 300 = 800
And similarly, all three terms are 1280, 2048, and 3276.8.
Hence "All five terms of GP are 500, 800, 1280, 2048, and 3276.8".

At the beginning of the year, Sadie had $70 in savings and saved an additional $18 each week thereafter. Jack started the year with $90 and saved $14 every week. Let S S represent the amount of money Sadie has saved t t weeks after the beginning of the year and let J J represent the amount of money Jack has saved t t weeks after the beginning of the year. Write an equation for each situation, in terms of t , t, and determine the amount of money Sadie and Jack have saved in the week that they have the same amount of money saved.
Answers
Answer:
$160Step-by-step explanation:
Step one:
For Sadie
initial savings balance= $70
weekly savings = $18
Let S represent the amount of money Sadie has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
S=18t+70-------1
For Jack
initial savings balance= $90
weekly savings = $14
Let J represent the amount of money Jack has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
J=14t+90---------2
Step two
equation 1 and 2 to find t
18t+70=14t+90
18t-14t=90-70
4t=20
divide both sides by 4
t=20/4
t=5 weeks
so after 5 weeks Sadie and Jack will have the same amount of money
For Sadle t=5
S=18(5)+70-------1
S=90+70
S=$160
For Jack t=5
J=14(5)+90---------2
J=70+90
J=160
The two equations above shows that after 5 weeks their savings will be $160

Question 7
Answer:
The graph in question 7 is a function.
Step-by-step explanation:
In order to check whether the graph in question 7 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.
It is observable that the vertical line will always intersect the graph in question 7 at the only place.
From the graph, it is clear the green vertical line intersects the graph at the only place. Hence, the graph in question 7 is a function.
Therefore, the graph in question 7 is a function.
Question 8
Answer:
The graph in question 8 is not a function.
Step-by-step explanation:
In order to check whether the graph in question 8 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.
It is observable that the vertical line intersects the graph in question 8 at more than one place.
From the graph, it is clear the green vertical line intersects the graph at x=-3 at more than one place. We can not have the same x values for the two output values in order to be a function. Hence, the graph in question 8 would NOT be a function.
Therefore, the graph in question 8 is not a function.
what is true about the number of sides in any regular polygon that has at least one line of symmetry passing through two vertices
Answers
Step-by-step explanation:
A regular n-sided polygon has n lines of symmetry. If n is odd, each line of symmetry passes through only one vertex. If n is even, half the lines pass through two vertices, and half pass through none.
So if a line passes through two vertices, the polygon must have an even number of sides.
