Can someone please help me with these three questions?

Answer:

x = -3/10

Step-by-step explanation:

1/2(2x - 1) = -1/5 -3/5

Combine like terms

1/2(2x - 1) = -4/5

Multiply each side by 2

2* 1/2(2x - 1) = -4/5*2

2x-1 = -8/5

Add 1 to each side

2x-1+1 = -8/5 +1

2x = -8/5+5/5

2x = -3/5

Divide by 2

2x/2 = -3/5 * 1/2

x = -3/10

Answer:

270 - 65.95 - 32.63 = 171.42

171.42 ÷ 14.85 = 11

I belive the answer is 11

Answer:

12

Step-by-step explanation:

I can’t help you with this but I recommend speaking with the teacher or asking a friend for the notes. I’m sorry if I fully didnt help you. It’s just that I’m in a diff class than you.. best of luck :)

Answer:

The line with blue dots is steeper.

Step-by-step explanation:

The higher the slope means a steeper line.

If we get 2 points from the line with blue dots (1,3) and (2,6) and plug it into the formula to find the slope, (y1-y2) / (x1-x2), the slope is 3.

To find the slope of the line with black dots, we do the same thing just with different coordinate points, (1,2) and (2,4). The slope is 2, which is less than the slope of the other line.

Therefore the line with blue dots is steeper.

Answer:

First thing i noticed was that the height has a big difference in both graphs. Also blue is more spaced out and has more steepness in it Compared to the black graph. Blues steepness is greater by 4 units.

Step-by-step explanation:

Hoped i helped :)

(could you let me know if I’m helping? thanks)

Answer:

either the second one or the fourth one. good luck

Step-by-step explanation:

Answer:

A. The number of days Harrison has read since he started the project.

Answer:

Base = 8x8=64

face 1 = 4x5=20

All faces = 20x4=80

80+64=144m squared

Step-by-step explanation:

70-26= 44°

Might be wrong but hope it helped!

Answer:

Hello! answer: p = 44

Step-by-step explanation:

These are vertical angles!

Meaning that each will equal the same

Since we are given its vertical angle we know that it will have to add up to 70 on the other side as well so...

70 - 26 = 44 therefore p = 44 hope that helps!

Answer:

A

Step-by-step explanation:

Multiply 5 with the expression in the bracket you will get 60y-90-20x

Answer:

1.) n ≥ 22/3

2.) t > 44

3.) You can buy 5 hot dogs

Step-by-step explanation:

Question 3 explanation:

You can buy 5 hot dogs at the baseball game because each hot dog is $2. If you have $10 then 5 x 2 = 10

Answer:

both include shooting accuracy

both can be done outdoors

both have to be thrown into some type of goal to score points

both require practice to be good

both involve throwing of some sort

Step-by-step explanation:

Answer: x+x=2x

Step-by-step explanation:

Well, it says there are half of the objects in two baskets of the third one.

So x (first box) + x (second box) = 2x (third box)

(also mayumi needs to learn to save boxes too)

Happy to help :)

Answer:

16

Step-by-step explanation:

you do 2+2 which is 4 then 8/2 is 4 and you multiple 4*4

Answer:

x+16=4x-5

x-4x= -5 -16

-3x =-21

-3x/-3= -21/-3

x=7

Answer:

x = 52

The exterior angle of a triangle is equal to the sum of the opposite interior angles

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

x+72 = 90+34

Combine like terms

x+72 = 124

Subtract 72 from each side using the subtraction property of equality

x+72-72 = 124 -72

x =52

The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(2x + 1) = 2 (4x - 7) + 3

Using distributive property, a(b + c) = ab + ac

10x + 5 = 8x - 14 + 3

10x + 5 = 8x - 11  [associative property of addition]

10x - 8x + 5 = -11

2x + 5 = -11  [Combine like terms]

2x + 5 - 5 = -11 - 5

2x = -16 [ Addition property of equality]

2x / 2 = -16/2

x = -8  [multiply by LCD]

Hence the justifications are done.
