d. The opposite of - 10t and t - 10t
Answer:
The answer is t.
Step-by-step explanation:
We need to find the sum of opposite of - 10t and t - 10t.
Opposite of -10t = 10 t
So,
10t + (t-10t)
Grouping the numbers,
(10t+(-10t)) + t
= 0 + t
= t
Hence, the answer is t.

Which expression is equivalent to 12(4m−2n+4)?
1.2m−n+2
2.2m−2n+4
3.8m−4n+4
4.8m−4n+8
Answer:
1. 2m - n + 2
Step-by-step explanation:
12×4m - 12×2n + 12×4. ( because 12 is multipled by whole bracket)
48m - 24n + 48.
2m - n + 2. (by finding common factor 24)

The scale factor from the large triangle to the small triangle is 3:1 What is the length of side x of the smaller triangle?
Answer:
10 i guess
cause
8*3=24
3*10=30
Step-by-step explanation:
Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)
Therefore 3x = 30 and x = 10.
A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?
A. 3,807 mph
B. 1,266 mph
C. 432 mph
D. 423 mph
Answer:
423 mph
Step-by-step explanation:
To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.
Step-by-step explanation:
A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?
1,269 % 3 = 423

An express train travelled at a certain average speed from Town X to Town Y which was
150 km away. It then continued its journey to Town Z at an average speed 20 km/h faster than
its initial average speed. Town Ywas 200 km from Town Z. If it took the same time to travel for
both parts of the journey, what was the train's average speed for the first part of the journey?
Answer:
60 km/hr
Step-by-step explanation:
Let the speed at the initial average speed from Town X to Town Y be a.
We are told that it journeyed to Town Z at an average speed 20 km/h faster than its initial average speed. Thus, its average speed here is (a + 20) km/hr.
Town Y was 200 km from Town Z.
Thus, time spent here is;
t_2 = 200/(a + 20)
Time from X to Y is; t_1 = 150/a
We are told that it took the same time to travel for both parts of the journey.
Thus; t_1 = t_2
150/a = 200/(a + 20)
Cross multiply to get;
150(a + 20) = 200a
150a + 3000 = 200a
200a - 150a = 3000
50a = 3000
a = 3000/50
a = 60 km/hr

Which operation should you do first when you simplify the expression below?
(15+4)x3
Answer:
I would assume you would use PEMDAS? thats what I would use
Answer:
Solve the parenthesis
Step-by-step explanation:
In the order of operations (PEMDAS), you would solve what's in the parenthesis first. So you would add 5 and 4, then multiply that by 3 to get the correct answer. Hope that helps!

Step-by-step explanation:
[tex] \dfrac{x + 2}{x^3 + 2x^2 - 9x - 18} \div \dfrac{3x + 1}{x^2 - 9} = [/tex]
Factor all polynomials.
[tex] = \dfrac{x + 2}{x^2(x + 2) -9(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x^2 - 9)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
To divide by a fraction, multiply by its reciprocal.
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \times \dfrac{(x + 3)(x - 3)}{3x + 1} [/tex]
Cancel out common factors in the numerator and denominator.
[tex] = \dfrac{1}{3x + 1} [/tex]

1. The list of ordered pairs represents a function: (12,6) (3,1) (2,-2) (5,10) (-8,-4) ( _, _)

A. (2,1)
B. (12,7)
C. (-8,8)
D. (-3,-4)
2. Rita works at a gym where she gets paid $450 each week plus $15.50 for any new gym membership she sells. If y represents the total pay per week and x represents the number of new memberships sold, which of the following equations represents a higher rate per membership sold.
A. y =31/3x + 500
B. y =15x + 425
C. y =33/2x + 425
D. y =15.05x +475
Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50

Combine like terms to create an equivalent expression. 4\left(1.75y-3.5\right)+1.25y4(1.75y−3.5)+1.25y
Answer:
8.25y + 14
Step-by-step explanation:
Given the expression
[tex]4\left(1.75y-3.5\right)+1.25y[/tex]
We are to simplify it as shown
Open the parenthesis
4(1.75y) - 4(3.5) + 1.25y
7y - 14 + 1.25y
Collect the like terms
7y + 1.25y - 14
8.25y + 14
Hence the required expression is 8.25y + 14

1. Ryan and Rachel attended the weekend games at the neighborhood stadium and bought some food at the stands Ryan paid $7.10 for 3 corndogs and 1 coke Rachel paid $7.20 for 2 corndogs and 2 cokes. How much is each corndog?
Please help :( I’ll give you brainiest ♡
Answer:
$1.75
Step-by-step explanation:
Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:
3x + y = 7.1
2x + 2y = 7.2
Solve by elimination by multiplying the top equation by -2
-6x - 2y = -14.2
2x + 2y = 7.2
Add them together:
-4x = -7
x = 1.75
So, the cost of one corndog is $1.75

how do i solve -3x + 2y = -4
Answer:
y= 3/2 x -2
Step-by-step explanation:
I guess you want to find the y=mx+b form
So you do +3x on both sides which will gave you: 2y= 3x-4
Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2
So 3/2 is the fraction like the answer above and -4/2 = -2
