I need help with my questions
Answer:
1) (-A+B)=(B-A) is true
Step-by-step explanation:
I am guessing you are looking for which statement is true. The answer is 1, (-A+B)=(B-A), as the others are incorrect.
2) A x 0 = 0, not 1
3) - (-A) = A, not - A
4) A/B will not be the same as B/A unless the values of A and B are 1
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Angie has 12 3/4 yards of fabric to make Halloween costumes. Each fabric costume requires 7/8 yards of fabric. How many costumes can Auntie make?
Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.
12 3/4 ÷ 7/8
= 51/4 ÷ 7/8
= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)
= 51/1 • 2/7 (after simplifying)
= 102/7
= 14 4/7
Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.

il will give you brainlyest if you show your work
Answer:
d = 109.3
87.9 + 21.4 = 109.3
109.3 - 21.4 = 87.9
Answer:
d-21.4=87.9
Step-by-step explanation:
d=87.9+21.4
d=109.3
d=109.3/1

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.

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
Is Y=x-3 and x-y=8 parallel perpendicular or neither
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

Ivan is curious if he can run faster than a rabbit.
He runs `90` feet in `5` seconds. The average rabbit can run at a speed of `35` feet per second.
Is Ivan faster than the rabbit?
Answer:
Step-by-step explanation:
Speed of rabbit per second = 35 ft
Ivan:
Speed in 5 seconds = 90 ft
Speed in 1 second = 90 ÷ 5 = 18 ft
No, Ivan is not faster than rabbit.
