Kristen spent $165 on shirts. Fancy shirts cost $15 and plain shirts cost $10. If she bought a
total of 16 shirts, how many of each kind did she buy?
Answer:
1 fancy 15 plain
Step-by-step explanation:
F + P = 16
15F +10P = 165
Miltiplu the 1st by -10:
-10F -10P = -160
15F + 10P = 165
Add both (10p is cancelled)
5F = 5
F =1
16-1 = 15 (15plain)
15 x10 =150
1x15 =15
150 +15 = 165

Is algebra.
Answer:
B
Step-by-step explanation:
The first one is a binomial. It has two different terms on either side of the middle minus sign. y is raised to the 4 th power so that is degree 4. The answer is b
The second problem is ordered as 4 3 1 2
The powers determine the degree. The terms are all different and the number of terms is determined by the powers of the letters in the terms.
Answer:
Step-by-step explanation:
What is the slope of the line that passes through the points (-4, 0) and (-4, -10)? Write your answer in simplest form.
Answer:
There is no slope.Step-by-step explanation:
[tex]slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It means that for a line passing through two points to have the slope, the x-coordinates of these point have to be different.
(-4, 0) and (-4, -10) means x₁ = x₂ = -4, so there is no slope.
{the line is parallel to Y-axis, and has an equation: x=-4}
Jim is on his way home in his car. He has driven 20 miles so far which is 1/2 of the way home. What is the total length of his Drive
Answer:40 miles per hour

how to u round to the decimal??????
O I KNOW USE A calculator
Answer:
To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.
Answer:
lol same. rounding decimals is just like rounding regular numbers
Example:
0.457 rounded to the nearest tenth...
5 rounds up so the answer would be 0.5
that's an example, please let me know if you need any other help!

Mr. Davis is packing a box with books. The box is a rectangular prism with the 2 ft 3 ft 2 ft What is the volume of the box?
Answer:
12 ft^3
Step-by-step explanation:
Given data
Dimension
Lenght= 2ft
Width= 3ft
Height= 2ft
The expression for the volume is
Volume= L*W*H
Substitute
V= 2*3*2
V= 12 ft^3
Hence the volume of the box is 12 ft^3
A cinema sold 1000 tickets on a Saturday evening. Adult tickets cost £9, children's
tickets cost £5, and a total of £6680 was collected
If there are a Adult tickets and c Children tickets, write down two simultaneous
equations connecting a and c.
Solve your equations to find how many tickets of each kind were sold.
Answer:
Step-by-step explanation:
a + c = 1000
9a + 5c = 6680
------------------------------
9a + 9c = 9000
9a+ 5c = 6680
------------------------------
4c = 2320
c = 580
------------------------------------------------------------
a+ 580 = 1000
a = 420
A = 420
C = 580
If you substitute the numbers into 9a + 5c = 6680, that should give you the right answer.

The graph shows the relationship between the number of apples and their cost. For the point (1, r), what is the value of r?
Answer:
C.
Step-by-step explanation:
When you check the point that is on X, it is a little over halfway to the point 1,2. It would be like 1,1.5 or 1,1.6.
5/3 is the equivalent to 1.6 so that answer would make the most sense.
Answer:
5/3
Step-by-step explanation:
3 Apples cost $5, so each apple cost 5 divided 3 ( 5 over 3).

Step-by-step explanation:
surface area = area of all the sides (incl. bottom)
area of the bottom is 5x5 ft = 25 ft^2
area of one side is (6x5)/2 = 15 ft^2
there are four sides so the total surface area is 25+4(15)= 85ft^2

The rate at which a mountain is eroding is given by y=0.5x, where y represents the amount of erosion in millimeters and x represents the amount of time in years. A field is eroding at a rate of 2 millimeters per year. Is the field or the mountain eroding at a faster rate? By how much?
Answer:
Field
Field is eroding 4 times faster than the mountain.
Step-by-step explanation:
[tex]y[/tex] = The amount of erosion in millimeters
[tex]x[/tex] = Number of years passed
[tex]y=0.5x\\\Rightarrow \dfrac{y}{x}=0.5[/tex]
The rate at which soil is eroding in the mountain is 0.5 millimeters per year.
The rate at which the field is eroding is 2 millimeters per year.
The field is eroding faster than the mountain.
[tex]\dfrac{m_f}{m_m}=\dfrac{2}{0.5}\\\Rightarrow m_f=4m_m[/tex]
So the field is eroding 4 times faster than the mountain.

Sam paid $8.28 for 18 stamps. At this rate, how much would it cost Sam to buy 12 stamps?
Answer: $5.52
Step-by-step explanation:
Given: Sam paid $8.28 for 18 stamps.
Thus, the cost of 18 stamps = $8.28
Then the cost of 1 stamp=
Thus, the cost of 1 stamp=$0.46
With the same rate , the cost of 12 stamps=
Therefore, the cost of 12 stamps= $5.52
hence, it costs $5.52 to Sam to buy 12 stamps.
8.28÷18 = 0.46
0.46 is the cost if 1 stamp
cost of 12 stamps= 0.46×12 = $5.52
