Jamie wants to sell popcorn for her local fundraiser. Each bag of popcom costs $5 and her grandmother gave her a donation of $18. How many bags of
popcom would she have to sell to meet her goal of raising $100? Which equation matches the situation?
Answer:
17, 100 - 18 = 82 which would be for me 5 because then it is divisible by 5 so 85 divided by 5 = 17 to completely finish her goal she would need which is a $100.
Joy Wigens, who works at Putnam Investments, received a check for $2,670. She deposited 1/3 of the check in her Citibank account. How much money does Joy have left after the deposit?
Answer: $1,780
Step-by-step explanation:
Joy Wigens deposited 1/3 of the check of $2,670 that she received in her Citibank account.
The amount she deposited in her Citibank account was:
= 1/3 * 2,670
= $890
The amount she is left with after this deposit will therefore be:
= Check amount - deposit at Citibank
= 2,670 - 890
= $1,780

Answer:
The length and breadth of the fence are 80 and 70 meters, respectively.
Step-by-step explanation:
Let suppose that fencing has a rectangular form. The length to breadth ratio is [tex]\frac{8}{7}[/tex]. Dimensionally speaking, the total cost for fencing the plot ([tex]C[/tex]), measured in monetary units, is the product of perimeter of the rectangle ([tex]p[/tex]), measured in meters, and unit cost ([tex]c[/tex]), measured in monetary units per meter, that is:
[tex]C = c\cdot p[/tex] (1)
[tex]C = 2\cdot c\cdot (w+l)[/tex] (2)
Where:
[tex]w[/tex] - Breadth of the fence, measured in meters.
[tex]l[/tex] - Length of the fence, measured in meters.
By applying the ratio described above, we reduce (2) into this form:
[tex]C = 2\cdot c\cdot \left(\frac{1}{r} +1\right)\cdot l[/tex] (3)
Where [tex]r[/tex] is the length to breadth ratio, no unit.
If we know that [tex]C = 60000[/tex], [tex]c = 200[/tex] and [tex]r = \frac{8}{7}[/tex], then the length and breadth of the rectangle are, respectively:
[tex]l = \frac{C}{2\cdot c\cdot \left(\frac{1}{r} +1\right)}[/tex]
[tex]l = \frac{60000}{2\cdot (200)\cdot \left(\frac{7}{8}+1 \right)}[/tex]
[tex]l = 80\,m[/tex]
[tex]w = \frac{l}{r}[/tex]
[tex]w = \frac{80\,m}{\frac{8}{7} }[/tex]
[tex]w = 70\,m[/tex]
The length and breadth of the fence are 80 and 70 meters, respectively.

Step-by-step explanation:
Plug in 2 for x in the equation: f(2) = 2(2) - 5
Remember order of operations/ PEMDAS
f(2) = 4-5
f(2) = -1
The total perimeter of the fence is 68 ft and the area is 240 square feet. Based on this information, what are the dimensions of the fence?
Answer:
6ft by 40ft
Step-by-step explanation:
Perimeter = 2(L+W)
Area = LW
L is the length of the fence
W is the width
Given
P = 68ft
A = 240ft²
Substitute into the formula
68 = 2L+2W ... 1
240 = LW... 2
From 1;
34 = L+W
L = 34-W ... 3
Substitute 3 into 2
From 2;
LW = 240
(34-W)W = 240
34W - W² = 240
- W²+34W = 240
W²-34W - 240 = 0
W²+6W-40W - 240 = 0
W(W+6)-40(W+6) = 0
W-40 = 0
W = 40feet
Since
34 = L+W
34 = L + 34
L = 6ft
Hence the dimension of the fence is 6ft by 40ft

Can someone solve this?
Answer:
Y=-5.6
x=.9
Step-by-step explanation:
Isolate the x:
6x=11+y
2x=7-3y
multiply top by 3 to get rid of y(3y and -3y cancel each other out)
18x=11
2x=7
put them together:
20x=18
divide by 20
x=0.9
to find y plug in x to the first equation:
y=6(.9)-11
y=5.4-11
y=-5.6
I hope this is right, and that it helps!

On a coordinate plane, a line goes through points (0, 2) and (2, 0).
Caleb graphed the linear function y = –x + 2 of a system of equations. The other linear function passes through the points (–2, –8) and (1, –2).
What is the slope of the linear function that passes through the points (–2, –8) and (1, –2)?
What is the y-intercept?
Graph the linear function to determine the solution. What is the solution?
Answer:
2 , -4 , (2,0)
Step-by-step explanation:
The slope of the linear function is 2.
The y-intercept of the linear function is -4.
The solutions of the linear function are (0, -4), (1, -2), (2, 0), etc..
The graph is given below.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The linear function is y = mx + c
The linear function passes through (-2, -8) and (1, -2)
Now,
m = (-2 + 8) / (1 + 2)
m = 6/3
m = 2
The slope of the linear function is 2.
Now,
(-2, -8) = (x, y)
-8 = 2 x (-2) + c
-8 = - 4 + c
c = -8 + 4
c = -4
The y-intercept is -4.
The equation of the linear function.
y = 2x - 4
The solution of the line are (0, -4), (1, -2), (2, 0), etc..
When x = 0,
y = -4
When x = 1,
y = -2
When x = 2,
y = 0
Now,
The graph of the line is given below.
Thus,
The slope is 2.
The y-intercept is -4.
The solutions are (0, -4), (1, -2), (2, 0), etc..

HELp pleaase ;Bbbbbbb
Answer:
the answer for this one is B
Answer:
The answer would be B.
Step-by-step explanation:
Just substitute x for 5.
For example, A is 2+x=3.
Just put 5 instead of x.
It would be 2+5=3.
But that isn't the answer because 2+5 is 7, not 3.
For B, sub the x for 5 just like we did for A.
It would usually be 3x=15
But sub the x with 5.
It would turn into 3x5=15
And that is right, because if you multiple 5 three times, it would be 15.
I hope this helps, I did my best. Have a great day!
