Answer:
$0.18
Step-by-step explanation:
we need to set up two simultaneous equations
using variables, pencils = p and erasers = e
3 pencils and 2 erasers, the cost is $0.76
3p + 2e = $0.76
2 pencils and 4 erasers, the cost is $1.04.
2p + 4e = $1.04
we now have
3p + 2e = $0.76
2p + 4e = $1.04
to make the number of erasers the same, multiply the first equation by 2 to give 4e
2(3p + 2e = $0.76)
6p + 4e = $1.52
now we have the same number of erasers for both equations
6p + 4e = $1.52
2p + 4e = $1.04
subtract across: 6p - 2p = 4p, 4e - 4e = 0, $1.52 - $1.04 = $0.48
we are left with 4p = $0.48
divide both sides by 4
p = $0.12
1 pencil = $0.12
go back to the start of both equations and use one of them to find 1 eraser. I'll use 3p + 2e = $0.76
input $0.12 in p
3($0.12) + 2e = $0.76
$0.36 + 2e = $0.76
subtract $0.36 on both sides
2e = $0.76 - $0.36
2e = $0.40
divide 2 on both sides
e = $0.20
1 eraser = $0.20
How much more does 1 eraser cost than 1 pencil?
we now know 1 pencil = $0.12 and 1 eraser = $0.20
find the difference between them
$0.20 - $0.12 = $0.18
final answer= $0.18
please help ASAP What is the surface area of the square pyramid represented by the net?
Answer:
144
Step-by-step explanation:
all of the triangles add up to 108m^2 and the middle adds up to 36m^2 so add them together and you get the surface area.
Answer:
144 m²
Step-by-step explanation:
From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width and length are equal).
First, find the area of the square.
Area of a square = width x length = 6 x 6 = 36 m²
All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.
Area of a triangle = 1/2 x base x height = 1/2 x 6 x 9 = 27 m²
So the total area of all 4 triangles = 4 x 27 = 108 m²
Therefore the total surface area = 36 + 108 = 144 m²

What value of x is in the solution set of 8x – 6 ≥ 12 + 2x?
Answer:
(Attached Below)
Step-by-step explanation:
Answer:
x [tex]\geq[/tex] 3
Step-by-step explanation:
8x - 6 [tex]\geq[/tex] 12 + 2x
First, take the smallest value of x away from the largest.
6x - 6 [tex]\geq[/tex] 12
Then, add 6 on both sides. (Always do the opposite!)
6x [tex]\geq[/tex] 18
Finally, divide by 6
x [tex]\geq[/tex] 3
Solve for X and Y substitution
-5X +6y=12
Y=5/6x+2
Answer:
Infinitely many solutions.
Explanation:
Given:
-5X +6y=12 .........eq 1
Y=5/6x+2 ..........eq 2
--------------------------------------------------------------------------
-5X +6y=12
6y = 12 + 5x .......eq 3
( Y=5/6x+2 ) * 6
6Y = 5X + 12 ...........eq 4
Using equation 3 and 4:
6y = 12 + 5x
6Y = 5X + 12
...............................
0
They are equal and cancels out. Therefore Infinitely many solutions.
6. rolling a 1, 2, or 3 on the first roll of a 1-6 number cube and
rolling a 4, 5, or 6 on the second roll of the same cube
Find the probability
Answer: The probability is 1/4
Step-by-step explanation:
The odds of rolling a 1,2, or 3 on the first roll is 3/6 or 1/2.
The odds of rolling a 4,5, or 6 on the second roll is also 3/6 or 1/2
The odds all together is 1/4 because 1/2 divided by 1/2 is 1/4.

Pilar bought 2/3 pound of turkey. She ate 1/4 of the turkey that she bought for lunch.
How many pounds of turkey did she eat?
Enter your answer in the box as a fraction in simplest form.
(20 points)
first change the fractions so they have common denominators.
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
now we can figure out how much she ate
8/12-3/12=5/12
So, Pilar ate 5/12 pounds of turkey.
Answer:
1/6

Let f(x) = 3x² + 1 and g(x) = x +4.
Find (f +g)(x)
and (f -g)(x).
Answer:
(f + g)(x) = 3x² + x + 5
(f - g)(x) = 3x² - x - 3
Step-by-step explanation:
(f + g)(x) → f(x) + g(x) → 3x² + 1 + x + 4
Combine like terms and you get: 3x² + x + 5
(f - g)(x) → f(x) - g(x) → 3x² + 1 - (x + 4)
Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3

Now you have 54 / 3
Now divide
54/3 = 18
answer: 18
Answer:
18
Step-by-step explanation:
PEMDAS
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
If the expression contains parentheses, always solve what's in them first
then if there are exponents, solve them
then do any multiplication or division, from left to right
last, do any additon or subtraction, from left to right
In this problem all we have to do is subtract 8 and 5 to get 3 and then divide that into 54 to get 18

What is the slope of the line? y - 4= -7(x-6) Choose 1 answer: 1 А. 7 4. B 7 --7 2 3
Step-by-step explanation:
the slope is always the factor of x.
in slope intercept form, as well as here in point slope form.
the important thing is that the y term is just brought to a simple positive y form (and not cy with c is different than 1).
and then, what you see on the other side as factor is x is the slope.
here : -7
the other numbers in the equating are irrelevant for the slope. they determine the "offset" of the line from (0, 0).
