An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers.
Which equation could be used to find n, the total number of markers in stock?
A:80 × 48 + 34 × 20= n
B:80 + 48 × 34 + 20 = n
C:80×48−34×20=n
D:80 + 48 + 34 + 20 = n
Answers
Because if you have 80 large boxes and a large box has 48 makers that would be 80x48 and the same thing for the small boxes which would be 34x20 the you would add both of this to get the total number of makers so it would be 80x48 + 34+20= n

Which number line represents 5/4?
Answers
Answer:
D.
Step-by-step explanation:
Determine 5/4 as a mixed number. 5/4 as a mixed number is 1 1/4.Eliminate the answer choices that are less than 1 or greater than 2 because 1 1/4 is between 1 and 2. In this case, you can now eliminate C.Eliminate the answer choices that are greater than 1 1/2 because 1 1/4 is between 1 and 1 1/2. In this case, you can now eliminate A.With your remaining answer choices, determine the number that each number line represents. You can see that B is split into sixths and five spaces are shaded, making it 6/5. On the other hand, D is split in fourths and 5 spaces are shaded, making it 5/4.With this information, you now know that D represents 5/4 or 1 1/4 and is your answer.I hope this helped.

Answers
180-(u+(u-47)) = 180 - (u + 48)
180 - (u + 48) is the unknown angle in the triangle as angles on a straight line = 180
180-(u+(u-47)) is also the unknown angle in the triangle as total angles in a triangle add up to 180.
180-(u+(u-47)) = 180 - (u + 48)
180-(u+u-47) = 180 - (u + 48)
180-(2u-47)= 180 - (u + 48)
180-2u+47 = 180 - u - 48
227-2u = 132-u
227-132 = -u+2u

Answers
Ok so basically we know that all the angles in a triangle add up to 180 degrees.
That means
(x-7) + (2x) + (x+11) = 180 because we combined all the angle measures.
To solve this equation we've got to combine like terms.
We can combine the x's together so we have 4x + (-7) + 11 =180.
Then we can combine -7 and 11 to get 4 because 11-7=4.
Now our equation is 4x+4=180.
We can subtract 4 from both sides of the equation to get 4x=176.
Then simplify this by doing 176/4=44.
That means x=44.

Answer:
z=32
Step-by-step explanation:
sum of these angles is equal to 180 so we add all of these angles and set it equal to 180
Z+12+2z+z+40=180
4z+52=180
-52. -52
4z=128
/4. /4
z=32
Hopes this helps
Answer:
z = 32° (degrees)
Step-by-step explanation:
Angles in triangle = 180° (degrees)
z + 12 + z + 40 + 2z = 180
2z + 2z + 12 + 40 = 180
4z + 52 = 180
4z = 180 - 52
4z = 128
z = 128/4 → 32

Answers
Answer:
x-intercept is -14/9 and y-intercept is -14
Step-by-step explanation:
Given equation is:
Determine the intercepts of the line is
y = (10/33)x
Solving step :
1. Find the y-intercept/zero
• Substitute y = 0
To find the y-intercept/zero, substitute y = 0.
y = 10x – 32y
0 = 10x- 32*0
• Calculate the product.
Any expression multiplied by 0 equals 0.
0 = 10x- 32*0
0 = 10x – 0
• Remove 0.
Removing 0 doesn't change the value, so remove it from the expression.
0 = 10x – 0
0 = 10x
• Swap the sides.
Swap the sides of the equation.
0 = 10x
10x = 0
• Divide both sides.
Divide both sides of the equation by 10.
10x = 0
10x ÷ 10 = 0 ÷ 10
Any expression divided by itself equals 1.
X = 0 ÷ 10
0 divided by any nonzero expression equals 0.
X = 0
2. Find the y-intercept.
• Substitute x = 0
To find the y-intercept, substitute x = 0.
y = 10x – 32y
y = 10*0 - 32y
• Solve the equation.
Solve the equation for y.
y = 10*0 – 32y
Any expression multiplied by 0 equals 0.
y = 0 – 32y
Removing 0 doesn't change the value, so remove it from the expression.
y = -32y
Move the variable to the left-hand side and change its sign.
y + 32y = 0
Collect like terms.
33y = 0
Divide both sides of the equation by 33.
y = 0
3. Find the slope-intercept form.
• Move the variable to the left.
y = 10x – 32y
Move the variable to the left-hand side by adding its opposite to both sides.
y + 32y = 10x - 32y + 32y
Since two opposites add up to 0, remove them from the expression.
y + 32y = 10x
• Collect like terms.
y + 32y = 10x
If a term doesn't have a coefficient, it is considered that the coefficient is 1.
1 y + 32 y
Collect like terms by adding their coefficients.
(1 + 32)y
Add the numbers.
33y
We did it!
y + 32y = 10x
33y = 10x
• Divide both sides.
Divide both sides of the equation by 33.
33y = 10x
33y ÷ 33 = 10x ÷ 33
Any expression divided by itself equals 1.
y = 10x ÷ 33
Write the division as a fraction.
y = (10/33)x

In A., there are 2 negatives, and 2 positives, so it would be a Positive. In B., There are 3 negatives, but there is a 0, and anything times 0 is 0, And 0 is neither negative nor positive. In C., All of the numbers are negative, so they cancel each other out, and make a positive. Lastly, In D., there is one positive, and three negatives. 2 Negatives cancel eachother out, and there is one negative and one positive remaining. A positive multiplied by a negative is also negative. So then the negative multiplied by the positive is negative.

Two angles of a triangle measure 27 and 17. What is the measure of the third angle?
Answers
Answer:
136⁰
Step-by-step explanation:
Three angles of a Triangle always addvup to 180⁰
27⁰ + 17⁰ + ×⁰= 180⁰
44⁰ + x⁰ = 180⁰
× = 180 - 44
= 136⁰
Therefore Angle 3 = 136⁰
Answer:
The third angle is 136
Step-by-step explanation:
The three angles of a triangle add to 180
27+17+x = 170
Combine like terms
44+x = 180
Subtract 44 from each side
44+x-44 =180-44
x =136
