Answer:
x = 4, y = 3
Step-by-step explanation:
2x - 3y = -1
- 2x + y = 11
-4y = -12
y = 3
solve for 'x':
2x -3(3) = -1
2x - 9 = -1
2x = 8
x = 4

Answer:
[tex]p=\$1.50,\\c=\$0.75[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}3p+2c=6.00,\\2p+3c=5.25\\\end{cases}[/tex]
Multiply the second equation by [tex]-\frac{3}{2}[/tex] to isolate and solve for [tex]c[/tex]:
[tex]\begin{cases}3p+2c=6.00,\\-3p-4.5c=-7.875\\\end{cases},\\-2.5c=-1.875,\\c=\fbox{$\$0.75$}[/tex],
Now plug in [tex]c=0.75[/tex] into any equation to solve for [tex]p[/tex]:
[tex]3p+2(0.75)=6.00,\\3p=4.50,\\p=\fbox{$\$1.50$}[/tex].
Answer:
One Slice of Pizza is $1.50
One cola is $0.75
Step-by-step explanation:
First, we need to define our variables:
x = pizza
y = cola
Next, we need to create two equations (one for Tanisha's order and one for Rachels order) using the information provided in the problem:
3x + 2y = 6.00
2x + 3y = 5.25
Now, we need to use one of the equations to solve for one of the variables:
3x + 2y = 6.00
2y = 6 - 3x
y = 3 - 1.5x
Next, we need to substitute y into one of the equations to find x:
2x + 3 (3 - 1.5x) = 5.25
2x + 9 - 4.5x = 5.25
-2.5x + 9 = 5.25
-2.5x = -3.75
x (or price per slice of pizza) = 1.50
Finally, we need to use the value we found for x to solve for y:
(2 x 1.5) + 3y = 5.25
3 + 3y = 5.25
3y = 2.25
y (or price per cola) = .75
I hope this helps!

2x^-2 y^-2 x= 3 and y = –2?
Answer:yes
Step-by-step explanation:
Answer:
1/18.
Step-by-step explanation:
2x^-2 y^-2
x= 3 and y = –2?
Answer is 2(3)^-2 * (-2)^-2
= 2/(3)^2 * 1/(-2)^2
= 2/9 * 1/4
= 2/36
= 1/18.

Answer:
The average rate of change is 4.
Step-by-step explanation:
Average rate of change is simply a fancy way of saying "find the slope".
So for slope, we use (y2-y1)/(x2-x1).

In 1990 it would have cost $3.70 to send 13 postcards and 7 letters. It would have cost
$2.65 to send 6 postcards and 7 letters. How much did it cost to send a letter in 1990?
Answer:
$0.37
Step-by-step explanation:
This can be solved by solving a system of linear equations that is shown above.
write an equation of the line and interpret the slope
Answer:
Step-by-step explanation:
Slope of this line will be= m= (600-200)/(1-5)
m = 400/-4 = -100
Eq of line will be:
(y-y1)=m(x-x1)
y-200=-100(x-5)
y-200+100x-500=0
100x+y-700 = 0
To write equation in slope-intercept form
y=mx+c
just seperate "y"
y=-100x+700
Hey there!
The answer to your question is [tex]y = -100x + 500[/tex]
To write this equation in slope-intercept form, first we must figure out the slope. We can do this using the formula
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]:
[tex]\frac{200-600}{5-1}[/tex]
[tex]\frac{-400}{4}[/tex]
[tex]-100[/tex]
Now, we have part of the equation: y = -100x + b. We have to find b, and we can do so by plugging in one of the points into the equation, like so:
[tex]600 = -100(1) + b[/tex]
[tex]600 = -100 + b[/tex]
[tex]500 = b[/tex]
Now, we have our equation:[tex]y = -100x + 500[/tex]
Hope it helps and have an amazing day!

A value is decrease by 92% for a new value of 13.12 find the original value
Step-by-step explanation:
Decreased by 92% = 8% of original
8% of original value = New value = 13.12
100% of original value = 13.12 * (100/8) = 164.
The original value is 164.

how do you Round 96,286 to the nearest thousand.
Answer:
The correct answer is 96,000
Step-by-step explanation:
To round you look at the thousands place and there is a 9 then you look at the number to the right of it which is 2 and it is lower than 5 since it is lower than five it rounds down so the correct answer is 96,000.
HAVE A GOOD DAY!
Answer:
96,000
Step-by-step explanation:
If the number on the right of the nearest thousand is lower than 5 the nearest thousand and the numbers to the left of it stay the same, while the numbers on the right turn into 0(zeros) but if the number in the right of the nearest thousand is 5 or grater then the nearest thousand would go up one digit while the numbers on the left of the nearest thousand stay the same, while the numbers on the right of the nearest thousand turn to zeros.
the ratio of length and breadth of a piece of land is 5:3 and its breadth is 48m. find the perimeter and area of the land.
Answer:
256 m and 3840 m²
Step-by-step explanation:
The 3 part of the ratio represents 48 m , then
48m ÷ 3 = 16 m ← value of 1 part of the ratio, so
5 parts = 5 × 16 m = 80 m
Then breadth = 48 m and length = 80 m
perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m
area = lb = 80 × 48 = 3840 m²

12. UZ, VX, and TW are medians of Triangle TUV. If YX = 8, find VY.
Answer:
VY = 16
Step-by-step explanation:
The median of a triangle is the segment that joins a vertex and the midpoint of the side opposite to this vertex.The point of intersection of the medians of a triangle, divide each median at ratio 2: 1 from the vertex.In the given figure
∵ TUV is a triangle
∵ UZ, VX, and TW are medians
∵ UZ ∩ VX ∩ TW at point Y
∴ Y is the point of intersection of the 3 medians
→ By using the 2nd rule above
∵ The point Y divide VX at the ratio of 2: 1 from the vertex V
∴ VY: YX = 2: 1
∴ [tex]\frac{VY}{YX}[/tex] = [tex]\frac{2}{1}[/tex]
→ By using cross multiplication
∵ VY × 1 = YX × 2
∴ VY = 2YX
∵ YX = 8
∴ VY = 2(8)
∴ VY = 16
A spinner with 5 equal section labeled 1-5 is spun 50 times. The results are shown in the table below. What is the theoretical probability of spinning an even number
Answer:
18/50
Step-by-step explanation:
The spinner was spun 50 times and both 2 and 4 are even numbers which was landed on 8 and 10 time so therefore 18/50
Answer:
i think its 2/5
Step-by-step explanation:
it says a probability of spinning an even number and there is 2 even numbers so out of the 5 there is 2 of them so it would be 2/5

1100 students attend Ridgewood Junior High School. 20% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
Answer:
20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).
Step-by-step explanation:
The day of the week is a distraction. All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.
