8 slices of pizza and 5 sodas cost $36.50. 4 Slices of pizza and 10 sodas cost $37. How much does a slice of pizza cost? How much does a soda cost?
PLEASE HELP
Step-by-step explanation: If we use the variable p to represent our pizzas and s to represent our sodas, if our first equation states than 8 slices of pizza and 5 sodas cost $36.50, that's 8p + 5s = 3650.
Notice that I expressed cost in terms of cents so
that we can avoid having to deal with decimals.
In our second equation, 4 slices of pizza and
10 sodas cost $37, that's 4p + 10s = 3700.
Now let's rewrite our two equations on top of one another.
8p + 5s = 3650
4p + 10s = 3700
To solve this system of equations, I would use addition.
I would multiply the bottom equation by -2
to create a situation where our p's will cancel.
When we do that, we get -8p - 20s = -7400.
Now rewrite the equations once again ~
8p + 5s = 3650
-8p - 20s = -7400
Now add the equations together.
So we have -15s = -3,750.
Divide both sides by -15 and s = 250.
Remember that I expressed cost in terms of cents so
since s = 250, it really means that a soda is $2.50.
Now just plug an s back in for the s in one equation.
When we do this, we find that p = 300.
So a pizza is $3.00

A cup of beans costs N160. How much
would a similar tin, three times the height
and diameter, full of beans cost?
Answer:
Below.
Step-by-step explanation:
The volume will be 3^3 = 27 times the volume of the small cup.
Answer is N160 * 27
= N4320.
The cost of a full of beans is N4320 if a cup of beans costs N160 and a similar tin, three times the height and diameter,
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have:
A cup of beans costs N160.
Cost of volume of a small cup = N160
Let V be the volume of a similar cup
V = 3³ = 27
The cost = 27×160 = N4320
Thus, the cost of a full of beans is N4320 if a cup of beans costs N160 and a similar tin, three times the height and diameter,

10. A rectangle has a perimeter of 22 cm. If the length of the rectangle is 2 cm more than two times the
width, what are its dimensions?
Answer:
w = 3 cm
l = 8 cm
Step-by-step explanation:
let 'w' = width
let '2 + 2w' = length
P = 2l + 2w
22 = 2(2 + 2w) + 2w
22 = 4 + 4w + 2w
22 = 4 = 6w
18 = 6w
w = 3
length = 2 + 2(3) = 18
it’s MATH who knows how to do this i’m down bad
Answer/Step-by-step explanation:
1. 7x + 2 = 5x + 22 (alternate interior angles are congruent)
Collect like terms
7x - 5x = -2 + 22
2x = 20
2x/2 = 20/2
x = 10
2. 13x - 6 = 10x + 24 (alternate interior angles are congruent)
Collect like terms
13x - 10x = 6 + 24
3x = 30
3x/3 = 30/3
x = 10
3. (12x + 26)° + 46° = 180° (same side interior angles are supplementary)
12x + 26 + 46 = 180
12x + 72 = 180
12x + 72 - 72 = 180 - 72
12x = 108
12x/12 = 108/12
x = 9
4. (5x + 5)° + 135° = 180° (same side interior angles are supplementary)
5x + 5 + 135 = 180
5x + 140 = 180
5x + 140 - 140 = 180 - 140
5x = 40
5x/5 = 40/5
x = 8

Of the people who fished at Clearwater Park today, 81 had a fishing license, and 9 did not. Of the people who fished at Mountain View Park today, 60 had a license, and 40 did not. (No one fished at both parks.) Suppose that one fisher from each park is chosen at random. What is the probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license? Do not round your answer.
Answer:
9/25 = the probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license
Step-by-step explanation:
There are 90 fishers at Clearwater and 100 fishers at Mountain View
The probability of a fisher at Clearwater had a license = 81/90 = 9/10
and the probability of a fisher at Mountain View
did not have a license = 40/100 = 2/5
the probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license = 9/10(2/5) = 9/25

Each row of bricks is 6.5cm and the number of row of bricks is r: 6.5r
Total of height of wall: = 259cm
Top row is 1cm shorter: -1cm
Combine all the terms together and we get: 6.5r - 1 = 259
Which means each row of bricks is 6.5cm but minus 1cm from the top to get 259cm the total :D

Which of the I-values are solutions to both of the following inequalities?
81> I and I > 68
Answer:
Option (C)
Step-by-step explanation:
Given inequalities are,
81 > x and x > 68
Therefore, 81 > x > 68 is the inequality representing the solution area for x.
Out of x = 88, 85 and 80,
x = 80 will lie between the range of x = 68 and x = 81.
Therefore, Option (C) will be the correct option.

find the value of each variable using sine and cosine. round your answers to the nearest tenth
Answer:
x=9.5 and y=15.3
Step-by-step explanation:
to find x you do sine of 32 = x/18 because the sine is opposite/hypotenuse
you put in a calculator sine (32) x 18 and get 9.538546756
so x equals 9.538546756 but it says to round to the nearest tenth so x equals 9.5
to find y you do the cosine of 32 = y/18 because cosine is adjacent/hypotenuse
cosine of (32) x 18 = 15.26486573 so you equals 15.26486573 but since you have to round to the nearest tenth y = 15.3
The value of x is 9.54.
The value of y is 15.3.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
From the figure,
Sin 32 = x / 18
Cos 32 = y / 18
Now,
Sin 32 = 0.53
Cos 32 = 0.85
Now,
0.53 = x / 18
Multiply 18 on both sides.
x = 0.53 x 18
x = 9.54
0.85 = y / 18
Multiply 18 on both sides.
y = 0.85 x 18
y = 15.3
Thus,
The value of x is 9.54.
The value of y is 15.3.
