Which line shows the first error in the solution? Three more than a number divided by 4 is -12. What is the number?
Explanation:
On the third line is where the student went from -12-3 to -9. This is not correct. Instead, it should be -12-3 turning into -15.
Think of it like being 12 feet under water (the number -12) and then moving 3 more feet deeper under water. You'll move down 3 to get to -15 to represent being 15 feet under water. Use a vertical number line if needed.
You can also compute -12-3 like 12+3 = 15, then just make everything negative. So -12-3 = -15
What are the measures of Angles a, b, and c?
Show your work and explain your answers.
Answer:
∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.
∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.

1. A local charity is collecting food for the winter. They have asked 150
families to donate 5 cans of food. If 80% of the families donate 5 cans of
food, how many cans should the charity collect? *
The charity should collect 600 cans of food
Number of families that the charity asked to donate food = 150
80% of the families donated 5 cans of food
Number of families that actually donated 5 cans of food = (80/100) x 150
Number of families that actually donated 5 cans of food = 0.8 x 150
Number of families that actually donated 5 cans of food = 120
Number of cans donated by each family = 5
Number of cans donated by 120 families = 5 x 120
Number of cans donated by 120 families = 600
The charity should collect 600 cans of food

Elizabeth uses 33.15 ounces of granola for 15 servings of trail mix.
If each serving contains the same amount of granola, how much granola is in each
serving?
Answer:
Step-by-step explanation:
We have to do 33.15 / 15 to find how much is in each.
We change 33.15 into a fraction
We get 33 3/20
We do 33 3/20 / 15 = 33 3/20 * 1/15 = 663/20 * 1/15 = 663/300 = 2 63/300
Therefore, 2 63/300 ounces of granola is in a serving.

Simplify
(2/3a - 5) - (1/3a + 3)
*Please show your work so I can’t understand better thank you*
Answer:
1/3a - 8
Step-by-step explanation:
Distribute negative sign:
2/3a - 5 + -1 (1/3a + 3)
2/3a + -5 + -1 (1/3a) + (-1)(3)
2/3a + -5 + -1/3a + -3
Combine like terms:
2/3a + -5 + -1/3a + -3
(2/3a + -1/3a) + (-5 + -3)
= 1/3a - 8

Answer:
252, 1 1/4, 308, 1 1/2
Step-by-step explanation:
5. The kitchen is 2 1/4 in by 1 3/4 in. 2 1/4in = 9/4in = 18ft. 1 3/4in = 7/4in = 14ft.
So we have 18ft by 14ft. The area is one side multiplied by the other side:
18 × 14 = 252ft^2.
6. 10/2 = 5. 5/4 in = 1 1/4in.
7. Bedroom 2 is 1 3/4in by 2 3/4in. 1 3/4in = 7/4in = 14ft. 2 3/4in = 11/4in = 22ft.
14ft × 22ft = 308ft^2 of carpet.
8. 12ft/2 = 6. 6/4 = 1 2/4 = 1 1/2 in.

(x,y)=(5,-3)In ANOP, NP is extended through point P to point Q, m_OPQ = (9x – 19)°,
mZPNO = (2x + 5), and mZNOP = (3x + 16º. Find mZNOP.
Answer:
The values of x and y are x = 6 and y = 9Step-by-step explanation:
MNOP is a parallelogram its diagonal MO and PN intersected at point A
In any parallelogram diagonals:
Bisect each other
Meet each other at their mid-point
In parallelogram MNOP
∵ MO and NP are its diagonal
∵ MO intersect NP at point A
- Point A is the mid-point pf them
∴ MO and NP bisect each other
∴ MA = AO
∴ PA = AN
∵ MA = x + 5
∵ AO = y + 2
- Equate them
∴ x + 5 = y + 2 ⇒ (1)
∵ PA = 3x
∵ AN = 2y
- Equate them
∴ 2y = 3x
- Divide both sides by 2
∴ y = 1.5x ⇒ (2)
Now we have a system of equations to solve it
Substitute y in equation (1) by equation (2)
∴ x + 5 = 1.5x + 2
- Subtract 1.5x from both sides
∴ - 0.5x + 5 = 2
- Subtract 5 from both sides
∴ - 0.5x = -3
- Divide both sides by - 0.5
∴ x = 6
- Substitute the value of x in equation (2) to find y
∵ y = 1.5(6)
∴ y = 9
The values of x and y are x = 6 and y = 9
Determine if the ordered pairs represent a function.

Answer: No
Step-by-step explanation:
There's no noticeable pattern.
Explain how to determine whether the difference of two numbers is less than or greater than the first number.
Answer:
To determine if the difference of two numbers is less or greater than the first number, check the value of the first number, and the value of the second number.
(greater) - (lesser) = (positive)
(lesser) - (greater) = (negative)
(neg lesser) - (neg greater) = (positive)
(neg greater) - (neg lesser) = (negative)
For Example:
10 - 5 = 5
5 - 10 = -5
(-5) - (-10) = 5
(-10) - (-5) = -5
