A.70
B.75
C.80
D.90
Answer: c. 80
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
First add all of the the test results 70+70+80+90+90=400 then you divided by how many test their were so 400/5=80

Step by-step explanation:
5. Using the equation y=2x+5, construct a table and graph the line
Step-by-step explanation:
What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.
So for X = 0
y = 2(0)+5 = 5
x = 1
y = 2(1)+5 = 7
x = 3
y = 2(3)+5 = 11
x = 5
y = 2(5)+5 = 15
x = 10
y = 2(10)+5 = 25
Now for what you do is place the correspanding value into the graph.
(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)
Answer: See the graph below.

Answer:
length= 35 feet and width= 10 feet
Step-by-step explanation:
You are given the perimeter of the rectangular deck is
90 feet.
2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5
Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.
2x (4 x width - 5) + 2 x width =90
Distribute the 2 though
8 x width - 10 + 2 x width = 90
Combine like terms with width.
10 x width - 10 = 90
Add 10 to both sides.
10 x width = 100
Divide both sides by 10 width = 100
Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5
Length = 4 x 10 - 5
Length = 40 - 5
Length = 35

Answer:
Option 4: 10d + 5
Step-by-step explanation:
Given the algebraic expression, 5(2d + 1), which represents the fines per day, d, for overdue books.
In order to determine the equivalent algebraic expression of 5(2d + 1), we must distribute 5 into the terms inside the parenthesis:
5(2d + 1)
= 5(2d) + 5(1)
[tex]\fbox{\textsf{= 10d + 5 }}[/tex]
Therefore, the equivalent expression is: 10d + 5.
what is the slope on an equation
Answer:
Formula
Slope of a line
Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).
Step-by-step explanation:
slope= dy/dx
=y2-y1/x2-x1

Rearrange terms, Combine multiplied terms into a single fraction, distribute, Multiply all terms by the same value to eliminate fraction denominators, Multiply all terms by the same value to eliminate fraction denominators . Cancel multiplied terms that are in the denominator . Multiply the numbers . Add 4 to both sides of the equation . Simplify.
Divide both sides of the equation by the same term . Simplify
Answer:
z = -3/2
Step-by-step explanation:
Our goal here is to solve -1/3 (4+z)=-5/6 for z.
Begin by multiplying both sides by 6, to eliminate the fractions:
-2(4 + z) = -5
Isolate (4 + z) by dividing both sides by -2: 4 + z = 5/2
Finally, determine z by subtracting 4 from both sides: z = 5/2 - 8/2 = -3/2
z = -3/2
Two school groups go to a roller skating rink. One group pays $243 for 36 admissions and 21 skate rentals. The other group pays $81 for 12 admissions and 7 skate rentals. Let x represent the cost of admission and let y represent the cost of a skate rental. Is there enough information to find values for x and y? Explain.
thxs
Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
There are infinitely many values of x and y are possible.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Two school groups go to a roller skating rink.
One group pays $243 for 36 admissions and 21 skate rentals.
The other group pays $81 for 12 admissions and 7 skate rentals.
Let x represent the cost of admission and let y represent the cost of a skate rental.
We have a system of equations,
36x + 21y = 243 {equation 1}
12x + 7y = 81 {equation 2}
Simplifying equation 1 we get,
36x + 21y = 243
Divide by 3,
12x + 7y = 81
That means, there are infinitely many solutions possible.
Therefore, there are infinitely many solutions possible.

A dugout needs to reach at least 72 feet below ground level. This means it needs to be more than 4 1/2 times its current depth. This depth is represented by the inequality 4 1/2 d < -72, where d is the current depth of the dugout.
The current depth of the dugout is ________ area feet below ground level.

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.
4 ¹/₂ d < - 72
Simplify the inequality, then we have
4 ¹/₂ d < - 72
4.5d < - 72
d < - 72 / 4.5
d < - 16
The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

A chef needs to choose a pan that will allow food to cook as quickly as possible for a special recipe and has decided that he will use one of three pans. Each pan has the same dimensions and design but is made of a different type of metal. The chef will design an experiment that will test and rank the thermal conductivity of the pans by cooking a hamburger patty to an internal temperature of 170 °F in each pan on the same stove burner. The thermal conductivity is the rate of transfer of energy in the form of heat over a period of time through a material.
Describe how thermal conductivity can be measured and compared for each of the pans.
