match each property with its corresponding example
Answer:
A: 3
B: 1
C: 5
D: 6
E: 4
F: 2
Step-by-step explanation:
A: The arrows should be a giveaway; you're distributing the 3 into the parentheses.
B: Step shows adding 12, and only one of those properties has anything to do with addition, the addition property of equality. The property basically says that if we already know that 6x - 12 is equal to 18, then if we add any number to both sides (given that the same number is added to both sides), the two sides will still be equal. The other properties, for subtraction, multiplication, and division work the same way except with a different operation.
C: Step shows multiplying both sides by 2, so it's the multiplication property of equality.
D: Step shows subtracting both sides by -6x, so it's the subtraction property of equality.
E: Step shows dividing both sides by 6, so it's the division property of equality.
F: Step shows combining two terms that both have x as a variable, so it's combine like terms.

Rebecca took a total of 12 quizzes over the course of 3 weeks. How many weeks of school will Rebecca have to attend this quarter before she will have taken a total of 24 quizzes? Assume the relationship is directly proportional.
Answer:
6 weeks
Step-by-step explanation:
If you look at the information it gives you, you can see it says 12 quizzes in 3 weeks and she needs 24 quizzes. So every 3 weeks she does 12 quizzes, and if you add 12 and 12 you get 6 weeks.

5.
Which two steps will complete the list correctly?
4. Divide the original measurement by the conversion factors.
5. Check for reasonableness,
4. Multiply the original measure by the conversion factors.
5. Simplify the answer.
4. Multiply the original measure by the conversion factors.
5. Check for reasonableness,
4. Divide the original measure by the conversion factors.
The final two steps used to convert units between different systems of measurement are given by;
Option C; 4. Multiply the original measure by the conversion factors.
5. Check for reasonableness
To answer this question, let us take an example of converting from inches to centimeters.
Let us convert 10 inches to centimeters.
First step is to identify the measure to be converted which in this case it is inches that is the measure.
Second step is to write the conversion factors which is;
1 inch = 2.54 cm
Third step is to cancel the units; In this case the units to be canceled will be inches.
Fourth step is to multiply the original measurement by the conversion factor to give; 10 × 2.54 cm = 25.4 cm
Fifth step is to check for reasonableness by trying to check if using another number will give a reasonable answer.

Annie and Ellie are each saving for college. Their grandmother gave
each of them $2500 to begin saving. Annie opened a savings account that
earns 2.4% simple interest while Ellie opened an account that earns 1.9%
interest compounded annually. In 7 years, who will have more money in
their account? How much more?*
Answer:
Annie will have $87.75 more than Ellie
Step-by-step explanation:
Annie :
2500(.024)7
Multiply all 3 together to get the answer
2500 x .024 x 7= 420
Ellie :
2500(.019)7
Multiply all three together to get the answer
2500 x .019 x 7 = 332.50

What is the distance between the points M (-3, 7) and N (a, b)?
Answer: [tex]\sqrt{ (-3-a)^2 + (7-b)^2 }[/tex]
Explanation:
We plug the given coordinates into the distance formula
[tex]d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 }\\\\[/tex]
There isn't much we can do from there since we don't know the values of 'a' or 'b'. You could expand out each binomial, but it's more simplified being factored like that.
A car and a bus which are 280 miles apart are driving towards each other. The car is moving at 50 mph while the bus is moving at 55 mph. How long will it take them to meet?
Answer:
2.6667 hours
Step-by-step explanation:
Given that:
Distance between car and bus = 280 miles apart
What le moving towards each other ;
Speed of car = 55 mph
Speed of bus = 50 mph
Time it will take them to meet;
Time = distance / speed
Hence :
Total distance to be covered = 280 miles
Total speed = (55mph + 50 mph) = 105 mph
Hence ,
Time = 280 miles / 105 mph
Time = 2.667 hours
2 hours, (0.667 * 60 = 40.02
2 hours, 40 minutes
Answer:
2.6667

Answer:
(-10,-3)
Step-by-step explanation:
okay so first, we can plot the points (-3,2) and (4,7) on a graph. after graphing these points, look at the difference between the y-values. this is 5 because 7-2 is 5. now, look at the x-values. this is 7 because 4-(-3) is 7. so this means we have to go on the other side of the midpoint (-3,2) and go 5 lines down from that point. this brings us at (-3,-3). now, we have to go 7 lines to the left. this is (-10,-3). this is the other endpoint.
you can also graph this on desmos to double-check.
hope this helps:)
After a parade, a group of volunteers is helping to pick up the trash along a 2-mile stretch of a road.The group decides to divide the length of the road so that each volunteer is responsible for cleaning up equal-length sections.Find the length of a road section for each volunteer if there are 8 volunteers
Answer:
it is .25 :)

Answer:
0.08 mile or 422.4 feet
Step-by-step explanation:
Distance=2 miles
number of volunteers=25
Length for each volunteers
[tex]2\frac{2}{25} miles=0.08 mile\\[/tex]
= 422.4 feet (as mile = 5280 feet)
0.08 mile or 422.4 feet

What is the equation of the line that passes through the point (-1,4) and has a slope of -5?
Answer:
y = -5x + 4
Step-by-step explanation:
In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.
Answer:
y = -5x - 1
Step-by-step explanation:
Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.
Point slope formula = y - y = m(x - x)
m = -5 (-1, 4)
y - 4 = -5(x +1)
y - 4 = -5x - 5
y = -5x - 1

what is 8+4d=5d i really need help
Answer:
d = 8
Step-by-step explanation:
Given
8 + 4d = 5d ( subtract 4d from both sides )
8 = d
Answer:
d=8
Step-by-step explanation:
8+4d=5d
1. subtract 8 from both sides > 8+4d-8=5d-8
2. simplify > 4d=5d-8
3. subtract 5d from both sides > 4d-5d=5d-8-5d
4. simplify again > -d = -8
5. divide both sides by -1 > -d/-1 = -8/-1
6. simplify again > d=8

Answer:
10
Step-by-step explanation:
Answer:
9 times 6
