Which expression is equivalent to 7/12(24 - 12m) - 1/3(21m + 27)? 5
7m+2
-14m+5
-14m+23

Answers

Answer 1

Answer:

The requried simplified equivalent expression to the given expression is -14m+5. Option C is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
= 7/12(24 - 12m) - 1/3(21m + 27)

Simplifying the above expression,
= 14 - 7m - (7m + 9)
= 14 - 9 -7m -7m
= 5 - 14m or -14m + 5

Thus, the requried simplified equivalent expression to the given expression is -14m+5. Option C is correct.

Answer 2

Answer: ⁷/₁₂(-12m + 24) - ¹/₃(21m + 27)
⁷/₁₂(-12m) + ⁷/₁₂(24) - ¹/₃(21m) - ¹/₃(27)
-7m + 14 - 7m - 9
-7m - 7m + 14 - 9
-14m - 5

Which of the following is an example of an improper fraction?a. 6/7
b. 3/10
c. 10/3
d. 4/5

Answers

Improper fractions are called such because the numerator is greater than the denominator. The only way it can be simplified is through a mixed fraction.

c) 10/3 is the improper fraction.

10/3 is simplified into 3 1/3.

(3x - 8) - (x2 - 5x - 2)

Answers

Answer:

-x^2 +8x -6

Step-by-step explanation:

Distribute the minus sign and collect terms.

(3x -8) -(x^2 -5x -2)

= 3x -8 -x^2 +5x +2

= -x^2 +8x -6

you can type 250 characters in 60 seconds your friend can type 375 characters in 90 seconds do these ratios form a proportion

Answers

Answer:

see the explanation below

Step-by-step explanation:

you can type 250 characters in 60 seconds your friend can type 375 characters in 90 seconds do these ratios form a proportion

Given data

you can type 250 characters in 60 seconds

your typing speed = 250/60

= 4.16 characters per seconds

your friend can type 375 characters in 90 seconds

your friends typing speed is

= 375/90

= 4.16 characters per seconds

Since both typing speeds corresponds, hence the ratios are proportional

The graph shows two lines, A and B:A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6. Another straight line labeled B joins the ordered pair 0, 0 and the ordered pair 5, 5.

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

A (0, 6) is the solution to both lines A and B.
B(0, 6) is the solution to line B but not to line
C(2, 2) is the solution to both lines A and B.
D (2, 2) is the solution to line A but not to line

Answers

The correct answer for the question that is being presented above is this one: "A (0, 6) is the solution to both lines A and B." The statement that is correct about the solution to the system of equations for lines A and B is that (0, 6) is the solution to both lines A and B.

Answer:

C(2, 2) is the solution to both lines A and B.

Step-by-step explanation:

Line A is given as:

A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.

We know that the equation of a line passing through (a,b) and (c,d) is calculated as:

$y-b=(d-b)/(c-a)* (x-a)$
