Answer:

x = 6

Step-by-step explanation:

∡J = ∡K and ∡M = ∡L

because this is an isosceles trapezoid

∡J + ∡M = 180°

because angles at opposite bases are supplementary

then ∡J + ∡M = 180°

∡J = (7x + 2)°

∡M = ∡L = (25x - 14)°

so:

(7x + 2 + 25x - 14)° = 180°

(32x - 12)° = 180°

32x = 180 + 12

32x = 192

x = 6

Answer:

x= 8/9

Step-by-step explanation:

7x + 2 = 25x - 14

-7x         -7x

2 = 18x - 14

+14       +14

<u>16</u> = <u>18x</u>

18     18

x=8/9

50. At a booth at the school carnival in past years, they've found that 32% of students win a stuffed toy ($3.25), 10% of studen
kipiarov [429]

Answer:

The expected amount to be paid by the carnival committee for prices would be $366.80

Step-by-step explanation:

Hello!

Here, we want to calculate the amount of money the carnival committee is expected to pay for the prizes for that booth

From the question, we have 3 categories of prices to be won

To calculate for people that won’t win anything , we simply subtract the percentages of all from 100

That would be 100-32-10-8 = 100-50 = 50%

So now let’s calculate the number of people out of 200 that will win each category based on the percentages

For stuffed toy

32/100 * 200 = 64

Jump rope

10/100 * 200 = 20

For t-shirt

8/100 * 200 = 16

So total price paid for stuffed toy= 3.25 * 64 = $208

For jump rope, we have 1.7 * 20 = $34

For t-shirt , we hav 16 * 7.8 = $124.8

So the total value spent on prices by the committee would be;

124.8 + 34 + 208 = $366.80

Find the surface area of this shape (here is the grid too)
Tanzania [10]

Answer:

12

Step-by-step explanation:

The second diagram is most helpful for finding the surface area.

  1. Find the area of the middle square: 2 * 2 = 4
  2. Find the area of the triangle using <em>A = 1/2*B*H,</em> so <em>A = </em>1/2 * 2 * 2 = 2
  3. Since there are 4 triangles, the surface area of all the triangles is 2 * 4 = 8
  4. Add the surface area of the triangles with the surface area of the square to get the total surface area: 8 + 4 = 12

What is the answer to 5/m-7=6/m-9?
valentina_108 [34]

Simplifying

5m + -7 = 6m + -9

Reorder the terms:

-7 + 5m = 6m + -9

Reorder the terms:

-7 + 5m = -9 + 6m

Solving

-7 + 5m = -9 + 6m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-6m' to each side of the equation.

-7 + 5m + -6m = -9 + 6m + -6m

Combine like terms: 5m + -6m = -1m

-7 + -1m = -9 + 6m + -6m

Combine like terms: 6m + -6m = 0

-7 + -1m = -9 + 0

-7 + -1m = -9

Add '7' to each side of the equation.

-7 + 7 + -1m = -9 + 7

Combine like terms: -7 + 7 = 0

0 + -1m = -9 + 7

-1m = -9 + 7

Combine like terms: -9 + 7 = -2

-1m = -2

Divide each side by '-1'.

m = 2

Simplifying

m = 2

Please help<br> Picture inserted <br> Multiple choice <br> Will appreciate it if u help!
Ksenya-84 [330]

Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.
