Answer:
Step-by-step explanation:
The secret trick to factoring is the greatest common factor.
The greatest common factor of 9 and 21 is 3. Thus, our expression is
3(3 + 7).
The greatest common factor of 14 and 28 is 7. Our expression is
7(2 + 4)
The greatest common factor of 80 and 56 is 8. This makes our expression
8(10 + 7).
Which expression is equivalent to 7(3a + 4b) ?
21a + 28b
10a + 11b
10a + 28b
21a + 4b
Answer:
A
Step-by-step explanation:
21a+28b

Zoe drove 55 miles in 11/12 hours. On average, how fast did she drive, in miles per hour?
Answer:
60
Step-by-step explanation:
So, first we need to divide the miles(55) by the time(11).
This should look like:
55/11
=
5
This should get you 5. Now lets multiply the 5 by the total time(12).
This should now look like:
5x12
=
60
This should get you 60. This is the answer.
If you want to solve more of these, here is a step-by-step:
Divide the value by the first time.Take the new value.Multiply it by the second time.This is your answerLets try another example:
Bob the builder made a 5 story building in 8 hours. How many stories on a building can Bob make in 24 hours?
Lets start with step 1. Divide the 5(value) by the 8(first time).
You should get 5/8 which is a bit of a strange number:
0.625
Now lets do step 2. Take the new 0.625 value.
Now to step 3. Lets multiply that value by the 24(second time)
This should get you 0.625x24:
This will get you 15
So your answer IN THE EXAMPLE I MADE is:
15 stories
Hope this make sense and helps you with your math ;)

Find the solution to 12x-2=13(x-15)
Answer:
x = 193
Step-by-step explanation:
distribute 13 into (x - 15)
=> 12x - 2 = 13x - 195
subtract 12x on both side
=> -2 = x - 195
add 195 on both side
=> x = 193

Find the perimeter of each polygon. Assume that lines which appear to be tangent are tangent.
9514 1404 393
Answer:
71.4
Step-by-step explanation:
The perimeter of the polygon is the sum of the lengths of its sides. Opposite sides in this geometry have the same sum, so the perimeter is ...
P = 2(16.4 +19.3) = 2(35.7)
P = 71.4 . . . units

There are 25 students. Four of these students are selected to attend four different conferences. The first student selected will go to
a conference in Makati city, the second will go to Paranaque city, the third to Quezon city and the fourth to Caloocan city. How
many such selections are possible?
256
12,650
303,600
390,625
Answer:
the number of possible selection is 12650
Option b) 12650 is the correct answer.
Step-by-step explanation:
Given the data in the question;
total number of students n = 25
number of student selected r = 4
[tex]^nC_r[/tex] = ²⁵C₄
= 25! / ( 4!( 25 - 4 )! )
= 25! / (4!(21)!)
= 12650
Therefore, the number of possible selection is 12650
Option b) 12650 is the correct answer.
Mrs. Stancil is planning to use
wrapping paper to cover a gift box that is the
shape of a rectangular prism with dimensions of
3ft by 4ft by 5ft. If the wrapping paper costs
S0.05 per square foot, how much will it cost?
Answer:
4.70
Step-by-step explanation:
there are 6 sides on a box
2 sides are 12 square feet (3*4), 2 sides are 15 square ft (3*5), and 2 sides are 20 square ft (4*5)
12*2+15*2+20*2=24+30+40=94 square feet
if each square foot costs $0.05 (I think that's what it says) then you would do 94*0.05= $4.70
so, your answer is $4.70

The slope of the line represented by the equation y= -2/3 - 5x is -5.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have,
y= -2/3 - 5x
We know from slope intercept form
y= mx + b
Where m is the slope and b is the y intercept.
Now, Comparing with given equation we get
m = -5 and b= -2/3
Thus, the slope of line is -5.

Coal gas is produced at a gasworks. Pollutants in the gas are removed by scrubbers, which become less and less efficient as time goes on. The following measurements, made at the start of each month, show the rate at which pollutants are escaping (in tons/month) in the gas: Time (months) 0 1 2 3 4 5 6 Rate 5 7 9 14 22 31 40 A.

A. Make an overestimate and an underestimate of the total quantity of pollutants that escape during the first month.
Overestimate
For this case, we review the data in the table. The value for first month of total quantity of pollutants that escape is 7. Additionally, we can notice that the rate is increasing.
Just a month and that month has a value of 7
= 1* 7 (The largest value) = 7

Mr. Nelson sold a car for $1,380 that cost
him $1,500. What was his percent of loss
based on the cost?
Answer:
The loss is $120 and the loss percentage is 8%.
Step-by-step explanation:
Given that,
SP of a car = $1,380
CP of a car = $1,500
As CP > SP, it means there is a loss in selling of that car.
Loss = CP - SP
= $1,500 - $1,380
= $120
Loss percentage,
[tex]\%=\dfrac{loss}{CP}\times 100\\\\=\dfrac{120}{1500}\times 100\\\\=8\%[/tex]
Hence, the loss is $120 and the loss percentage is 8%.

Write an equation to represent the relationship between red paint, r, and yellow paint, y, in each batch.
The equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given:
At r = 2, y = 3,
r = 4, y = 6,
r = 6, y = 9
Here, r is red paint and y is yellow paint.
The above condition can be written as
2r = 3y
r = 3 / 2y
Therefore, the equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.
