Where can we put parentheses in 45 – 22 +9 to make it equivalent to 14?
Choose 1 answer.
45 – (22 +9)
(45 – 22) +9
Answer:
45 – (22 + 9)
Step-by-step explanation:
45 – (22 + 9) = 45 - 31 = 14
(45 – 22) + 9 = 23 + 9 = 32
Answer:
45 – (22 + 9)
Is 2/3 x 5/8 the same as 5/8 x 2/3 explain.
Answer:
2/3 x 5/8 = 5/8 x 2/3 is True
Step-by-step explanation:
Simplify the following: Left-Hand
2/3×5/8
2/3×5/8 = (2×5)/(3×8):
(2×5)/(3×8)
2/8 = 2/(2×4) = 1/4:
5/(3×4)
3×4 = 12:
Answer: 5/12
___________________________
Simplify the following: Right-Hand
5/8×2/3
5/8×2/3 = (5×2)/(8×3):
(5×2)/(8×3)
2/8 = 2/(2×4) = 1/4:
5/(4×3)
4×3 = 12:
Answer: 5/12
so a machine makes 80 copies in 2 1/2 min how many copies does it make in 0.25 min
Find copies per minute:
80 / 2.5 = 32 copies per minute.
Multiply copies per minute by total minutes:
32 x 0.25 = 8 copies

David has two jobs. He earns $8 per hour babysitting his neighbor's children and he earns $11 per hour working at the coffee shop. If David worked 15 hours at the coffee shop, write an inequality to represent the number of hours, x, babysitting that David will need to work to earn a minimum of $200. Use the inequality to find the number of full hours he must babysit to reach his goal of $200.
Answer:
The number of full hours he must babysit to reach his goal of $200 is 5 hours
Step-by-step explanation:
Let x be the no. of hours he must babysit to reach his goal of $200.
Cost for working 1 hour at coffee shop = $11
Cost for working 15 hour at coffee shop = [tex]11 \times 15=165[/tex]
Cost for working 1 hour babysitting = $8
Cost for working x hour babysitting = 8x
We are supposed to find the number of full hours he must babysit to reach his goal of $200.
165+8x=200
8x=200-165
[tex]x=\frac{200-165}{8}[/tex]
x=4.375
Hence The number of full hours he must babysit to reach his goal of $200 is 5 hours

1. What are the equation and slope of the line shown on the grid?
Answer:
y=2/5x-2
Step-by-step explanation:
The main equation you will need for this is y=mx+b
First, you have to find the slope. the equation for that is
-2-0 = -2 (y)
0-5= -5 (x)
A good way to remember this is rise over run or y is always over x
Slope = 2/5 (The negatives cancel out)
The great thing about this is that they have already given you your "y" intercept or "b" which is -2

Answer:
x=63
y=27
Step-by-step explanation:
to find x
180-117=63
to find y
90-63=27
please mark brainliest if correct
Answer:
x=63, y=27
Step-by-step explanation:
x is part of a line with 117, so you would do 180-117 to find x. Then you do 90-63 to find y, which is 27.
Fred and Matt are playing basketball. If x represents the points Matt ended with, and 3x represents the points Fred ended with, what does that tell you about the relationship between Matt and Fred’s points?
It tells you that Fred has three times the score more than Matt.
This is because Matt has x points, Fred tops Matt by 3x points.

8. Classify 8 as a perfect square, a perfect cube, both, or neither.
Answer:
It's a perfect cube, but not a perfect square.
Step-by-step explanation:
2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

Lucia deposits $44.60 into her bank account on Tuesday Morning. Tuesday afternoon, she withdraws to $26.30 and $21.30. Does Luisa have more or less money on Tuesday night than she did on Monday night? Does this equation tell whether Luisa has more or less money on Tuesday night than Monday night? Explain.
Answer:
Less than
Step-by-step explanation:
Using the data from the question, we can create the following equation to solve this...
44.60 - (26.30 + 21.30) = x
44.60 - (47.60) = x
-3 = x
As you can see Lucia withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit. This can all be seen using the above equation which is designed.

Statment: Find the measure of the angle indicated by 19x+5
Options: 130
50
80
100
Answer:
100
Step-by-step explanation:
These two angles are corresponding which means they add up to 180.
so... 19x+5+(16x)=180
If you simplify...
35x+5=180
Then solve for x...
35x=175
x=5
Then take that 5 and fill it into 19x+5...
19(5)+5
95+5=100
Which expression is equivalent to cos(40°)cos(10°) + sin(40°)sin(10°)?
