subtraction sign will eliminate each other
and 5 divided by 25 is 5
therefore -25/-5=5

2.2 + 12x = -4
Answer:
−0.516667
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12x+2.2=−4
Step 2: Subtract 2.2 from both sides.
12x+2.2−2.2=−4−2.2
12x=−6.2
Step 3: Divide both sides by 12.
12x

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?
Answer:
42
Step-by-step explanation:
the ratio 2:4 can be reduced to 1:2,
where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.
If there are 14 girls, then there must be 28 boys (14 x 2 = 28).
Now to get the total number we need to add the total number of boys and girls together.
So 14 + 28 = 42
Hope it helps :)

Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.
Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?
The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Answer:
D. The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Explanation:
100%
Answer: The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?
Answer:
To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.
volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140
Final Answer: 140 one foot by one foot containers can fit in Mr. Powell's storage space

3% for 30 years. Jack will not make any
| additional deposits or withdrawals. How
X much interest will he have earned at the end X
of the 30 years?
Round your answer to the closest dollar

Answer:
Step-by-step explanation:
I think this is the equation for annual compunt interest
FV = PV(1 + int)^time PV is present value FV is the future value
PV + Interest = FV
FV - PV = Interest
FV - PV
Interest = [3000(1 + 0.03)^30] - 3000
= 3000(1.03)^30 - 3000
= 3000(2.4272) - 3000
= 7281.79 - 3000
= $4282 to the nearest dollar <------------ Fianl Answer

What is the decimal multiplier to increase by 6.1%?
first add or subtract the percentage from 100 ,then convert to a decimal.
What is a simple definition of the multiplier?
It is the number of times a rise in national income exceeds the rise in injections of demand that caused it.
What is the multiplier process?
The multiplier effect comes about because injections of new demand for goods and services into the circular flow of income stimulate further rounds of spending – in other words “one person’s spending is another’s income”
This can lead to a bigger eventual final effect on output and employment.

Which set of events would have an equally like chance of occurring?
A
spinning a spinner with 3 sections and tossing a coin.
B
rolling a six-sided cube and drawing 6 marbles out of a bag.
С
tossing a coin and choosing an odd number between 1 and 7
D
drawing 1 card out of 25 cards and choosing a letter out of the alphabet.
Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.
Option B is correct.
Probability:Probability of series of experiments shown below;
A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .
When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]
So that, set A has not equally like chance of occurring.
B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]
When one marble is drawn out of 6 marble in a bag, then probability is [tex]\frac{1}{6}[/tex]
Therefore, set B has equally like chance of occurring.

Find the slope of the line that passes through (10, 4) and (3, 1).

Subtract the y-coords, then the x-coords.

The slope is 3/7. Let me know if you need help graphing it too.
3 is the rise and 7 is the run. You start at (0,0) and you go up 3 units, then 7 units right. The first coordinate should be (7,3). Repeat until you have a straight line.

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?
Answer:
8
Step-by-step explanation:
You can solve this by creating a linear equation.
Slope: 2.50
Y-intercept: 4.70
y=2.50x+4.70
Since we know that the total fare was 24.70 we can plug it into the y.
24.70=2.50x+4.70
Now solve for the equation.
20=2.50x
8=x
So he went 8 miles with the taxi.
Total number or mile taxi run is 8 miles.
Given that;
Pick up charge = $4.7
Charges per mile = $2.5 per mile
Total fare = $24.7
Find:
Number of mile taxi ride
Computation:
Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]
24.7 = 4.7 + [Total number or mile taxi run][2.5]
[Total number or mile taxi run][2.5] = 24.7 - 4.7
[Total number or mile taxi run][2.5] = 20
Total number or mile taxi run = 20 / 2.5
Total number or mile taxi run = 8 miles
