What is m CBT? Use a protractor to help you.

Answers

m∠CBT is not 120°.

You have to notice the start of the measure of the angle is on the point of C. It is the 0°.

If the segment BT is straight up from the point of B, its angle will be 90°.

Since the segment does not form a right angle, its measure of angle is less than 90° but more than 0°

(-7, 3.5)

(7, 10.5)

(3.5, -7)

Answers

Answer:

(x, y) = (8, -1)
(x, y) = (7, 10.5)

Step-by-step explanation:

1. You can use the expression for y to substitute into the first equation:

2x +4(1/4x -3) = 12

2x +x -12 = 12 . . . . . . eliminate parentheses

3x = 24 . . . . . . . . . . . add 12; next divide by 3

x = 8 . . . . . matches choice C

2. You can use the expression for y to substitute into the second equation:

x -2(2x -3.5) = -14

-3x +7 = -14 . . . . . . eliminate parentheses

21 = 3x . . . . . . . . . . add 3x+14; next divide by 3

7 = x . . . . . matches the third choice

_____

When the answer choices are sufficiently different, you only need to find one value to determine which is the correct choice. (If you want to check your work further, you can substitute the other answer value into the two equations to see if it works.)

Which expression has a value of 36 when x=4 and y=7 A. 2xy B. 2x+4y C. 6y-x D. 12x-2y

Answers

x=4y=7
A. 2xy=2 times 4 times 7=2 times 28=56 not 36
B. 2x+4y=2 times 4+4 times 7=8+28=36 true

the answer is B

the answer is b, because 2x4 is 8, 4x7 is 28 and 8+28+36

the store is 5/6 mile from yuri's house. the bank is 2/5 the distance from yuri's house to the store, how many miles is the bank from yuris house

Answers

Answer:

$The\ bank\ from\ yuris\ house\ is (1)/(3)\ miles.$

Step-by-step explanation:

As given

$The\ store\ is\ (5)/(6)\ mile\ from\ yuri's\ house.$

$The\ bank\ is\ (2)/(5)\ the\ distance\ from\ yuri's\ house\ to\ the\ store.$

Than

$The\ bank\ from\ yuris\ house = (2)/(5)* (distance\ from\ yuri's\ house\ to\ the\ store) }$

$The\ bank\ from\ yuris\ house = (2* 5)/(5* 6)$

$The\ bank\ from\ yuris\ house = (10)/(30)$

$The\ bank\ from\ yuris\ house = (1)/(3)\ miles$

$Therefore\ the\ bank\ from\ yuris\ house\ is (1)/(3)\ miles$

distance of bank from yuri's house=(5/6)*(2/5)=2/6=1/3 mile
