Someone help me with this pls

Answer:

180/147

Step-by-step explanation:

We need to find the additive inverse of the given numbers.

SOLUTION 1 :-

→ 3/-7 - 11/21

→ -3/7 -11/21

→ 3×-3 - 11 /21

→ -9-11/21

→ -20/21

SOLUTION 2 :-

→ 9/5 ÷ 7/5

→ 9/5 × 5/7

→ 9/7

→ Product of nos . = -20/21 × -9/7

→ Ans = 180/147

Translate to the right 7 or 8 units

Answer

y = 0.2x − 7

Step-by-step explanation:

Find the slope first by subtracting (10, -5) and (5, -6) in slope formula, this will equal 1/5 or 0.2

Then find the y-intercept which is the point that crosses the y-axis, in this case -7 is the y-intercept

Finally format in y=mx + b for slope-intercept form

y=0.2x-7

Answer:

it's either a or b, but I would go with A

Answer:

the correct answer is A because the synonym 0f supplementary angle is straight angle and on obviously the sum of straight angle is 180⁰.

Answer:

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Step-by-step explanation:

2x + 3y = 12

5x - 2y = 11

2x + 3y + 5x - 2y = 11 + 12

7x + y = 23

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Answer:

Number of juice boxes people drank at Williams party = 91

Step-by-step explanation:

Total juice boxes Williams bought = 114

Juice boxes left over at the party = 23

How many juice boxes did people drink at William's party?

Number of juice boxes people drank at Williams party = Total juice boxes Williams bought - Juice boxes left over at the party

= 114 - 23

= 91

Number of juice boxes people drank at Williams party = 91

Answer:

9:30am

Step-by-step explanation:

To find what time simply add all of the minutes together and subtract. All of the steps take 100 minutes to do. 11.10 am is 670 minutes. So 670 - 100 = 570 then divide by 60 to get the time ie 9:30 am

Answer:

Step 1

Step-by-step explanation:

They're all wrong expansions but step 1 was where he made his first error... He shifted the bracket putting 3x inside the bracket... While the other steps the first expansion of 3x eliminating the bracket was correct.

The correct expansion is meant to be 3x + 21 + 5 = 3x + 26

I think the answer should be b, since y=3 when x=0, according to the option B.

y = x + 3, B

Answer:

55 centimeters

Step-by-step explanation:

It is a right triangle which means it will add up to 90 degrees. You would start by adding 20 and 15 which is 35 and then subtract 35 from 90 to get 55. I hope this helped :)

Answer:

(0, -2)

Step-by-step explanation:

The x- and y-coordinates indicate the position of a point in the 2D coordinate plane relative to the origin. The coordinates are written as an ordered pair of numbers (x, y), where x indicates horizontal position and y indicates vertical position.

Example

The position of the point in the figure below is specified by the ordered pair, (6, 4). 6 is the x-coordinate and 4 is the y-coordinate of the point.

Answer:

Step-by-step explanation:

1. Equation

3x + 4 = 25

2. Subtract 4 from both sides

3x + 4 = 25

     - 4    - 4

3. Solve

3x = 21

4. Divide both sides by 3

3x = 21

/3     /3

5. Solve

x = 7
