(52+2)-3x -6<br><br> help me with thanks

Yuri [45]

Answer:

48 - 3X

Step-by-step explanation:

( 52+2) - 3x - 6

54 - 3x - 6 So first we deal with the numbers in brackets and that is 52 + 2 giving us 54.

54 - 6 - 3x Then you simplify the expression that is collecting like terms so then we subtract 6 from 54

48 - 3x This is the final expression after simplifying

Which line is perpendicular to y=2x+5?

mezya [45]

Y = mx + n

m = Slope

To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1

y = 2x + 5
ma = 2

D: y = -1/2x + 5
mb = -1/2

ma x mb = -1

2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1

It's true.

Answer: D.

Which expressions are equivalent to this expression?

sashaice [31]

D & C are the correct answers.This is because of the Distributive Property.

y+y+y +3z = 3y + 3z.

3(y+z) also gives you 3y + 3z.

C is correct because everything adds up to 3y +3z:
2y+2z+y+z = 3y +3z

Last semester Jacob spent 1/3 of an hour doing math homework on each evening that he had math homework.he calculated that he spe

Marina CMI [18]

Jacob had math homework on 81 evenings.

Step-by-step explanation:

Time spent of each evening = 1/3 of an hour

Time spent in minutes = $\frac{1}{3}*60 = 20\ minutes$

Total time spent = 27 hours

Total time spent in minutes = 27*60 = 1620 minutes

Let,

x be the number of evenings spent doing math homework.

Time spent each day* Number of evenings = Total time spent

$20x=1620$

Dividing both sides by 20

$\frac{20x}{20}=\frac{1620}{20}\\x=81$

Jacob had math homework on 81 evenings.
