x=22

because…

2x-26+7x+8=180
9x-18=180
9x=198
x=22

Answer:

[tex]\Longrightarrow:\boxed{\sf{x=22}}[/tex]

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

Given:

[tex]\Longrightarrow: \sf{m: (2x-26)}\\\\\\\Longrightarrow: \sf{n: (7x+8)}[/tex]

[tex]\Longrightarrow: \sf{2x-26+7x+8=180}[/tex]

First, combine like terms.

[tex]\Longrightarrow: \sf{2x+7x-26+8=180}[/tex]

Add the numbers from left to right.

2x+7x=9x

[tex]\Longrightarrow: \sf{9x-26+8=180}[/tex]

-26+8=-18

[tex]\Longrightarrow: \sf{9x-18=180}[/tex]

Add by 18 from both sides.

[tex]\Longrightarrow: \sf{9x-18+18=180+18}[/tex]

Solve.

Add these numbers from left to right.

180+18=198

[tex]\Longrightarrow: \sf{9x=198}[/tex]

Divide by 9 from both sides.

[tex]\Longrightarrow:\sf{\dfrac{9x}{9}=\dfrac{198}{9}}[/tex]

Solve.

Divide the numbers from left to right.

198/9=22

[tex]\Longrightarrow: \boxed{\sf{x=22}}[/tex]

Therefore, the correct answer is x=22.

PLS HELP (answer isn't 1384.74 lol)

Answers

Answer:

1385mm squared

Step-by-step explanation:

Area of Circle formula: A = pi r^2

You need to divide 42mm by 2 since that is a diameter.

*Half of the diameter is the radius*

42/2 = 21

Now, do 3.14 multiplied by 21 to the power of 2.

Formula: A = 3.14 x 21^2

Do 21^2 first.

That shall be 441

Now do 3.14 x 441

1,384.74mm - That is your exact answer.

The directions tell you to round it to the nearest whole number

THAT IS 1385mm squared

Answers

Answer:

(a) 5

(b) 3rd quartile

(c) 2nd quartile

Step-by-step explanation:

There are four quartiles in a box plot (or box and whisker plot).

The 1st is from 5 to 13

The 2nd is from 13 to 35

The 3rd is from 35 to 40

The 4th is from 40 to 48

(a) The lowest that this box plot goes is 5 (between the 4 and 6)

(b) 3rd quartile — we can see that the left and right borders are close together, meaning that the data values for this quartile are close together, and therefore concentrated

(c) 2nd quartile — we can see that this quartile is the widest, and therefore the data values are spread out

A large box of biscuit mix costs $6.48. The box contains 72 servings of biscuit mix. One serving is equal to 1/4 cup of biscuit mix. This table shows the amount of mix and water needed to make different numbers of biscuits. (The table is the picture attached)

Part B
What is the total number of biscuits that can be made using one box of the biscuit mix?
Show your work or explain your answer.

Part C
What is the cost, in dollars and/ or cents, per biscuit? Show your work or explain your answer.

Answers

Answer:

Part A: Total number of cups of biscuit mix in one box is 18 cups.

Part B: You can make 54 biscuits using one box of biscuit mix.

Part C: 0.12 $ per biscuit.

Step-by-step explanation:

Part A: 72 x 1/4

Part B: In the chart, it shows us a pattern. The number of cups required times 3 =  the number of biscuits or vice versa. So the number of cups required is 18 and 18 x 3 is 54 so we can make 54 biscuits.

Part C: 6.48$/54

there are
no gaps between the cars? (1 meter = 1,000 millimeters)

Answers

25 train cars with each being 80mm long so 25x80 which equals 2000 and with each meter being equal to 1000mm the model train is 2meters long

Answer:

2,000 or 2 meters :)

Step-by-step explanation:

We must multiply :)

80 x 25 = 2,000

Since 1 meter equals 1,000 millimeters, 2,000 millimeters will equal 2 meters :)
