Answers

Answer 1

Answer: $(-8x) + x + (-2x)$

$-8x+x-2x$

$= -9x$

Answer 2

Answer: (-8x) + x + (-2x) = -8x + 1x - 2x = (-8 + 1 - 2)x = -9x

Circle is divided into 20 equal parts. What is the angle measure of three of those parts?

Answers

first, imagine a circle divided into 4 quarters
than you may use the following proportion

angle measure ------- part of circle
$90^0 - -----\frac14\n x \ \ ------\frac3{20}\n \n \frac14x=90^0\cdot\frac3{20}\n \frac14x=(270)/(20)\n \frac14x=\frac{27}2\ \ \ \ |\cdot4\n x=\frac{27}2\cdot4\n x=\frac{108}2\n \boxed{x=54\ degrees}$

What is the length of segment LP?

Answers

In the image, as denoted by similar sides OP and MN, we can conclude that the 2 triangles are similar triangles. To look for the value of x (which we can substitute later to find the length of segment LP), we relate the relations of segments LO and LP to segments LM and LN. This relation is shown below:

LO/LP = LM/LN

22 / x+12 = 30 / x+12 + 5
22 / x+12 = 30 / x+17

Cross-multiplying:
30x + 360 = 22x + 374

Isolating x to one side of the equation by subtracting 22x and 360 from both sides:

30x + 360 - 360 - 22x = 22x + 374 - 360 - 22x
8x = 14
x = 1.75

Since we now have the value of x, we substitute this to the equation of LP:
LP = x + 12
LP = 1.75 + 12
LP = 13.75

Therefore the value of LP is 13.75 in.

Simplify. 4−16÷4+42 −16 13 15 16

Answers

Answer:

[See Below]

Step-by-step explanation:

✦ First split the equation in little pieces and solve them:

✧ 4 - 16 = -12

✧ 4 + 4² = 20 (4² = 16)

✦ Now divide them:

✧ -12 ÷ 20 = -0.6

So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

Brownies are now on sale. Each brownie costs $0.20 less than the original price. Right now, if you buy 8 of them it will cost $15.20

Answers

Answer: The original price of brownie was $2.1 each.

Step-by-step explanation:

since we have given that

Let the original price will be x

Number of brownie purchased = 8

According to question , each brownie costs $0.20 less than the original price.

So, it becomes

$8* (x-0.20)=\$15.20\n\n8x-1.6=15.20\n\n8x=15.20+1.60\n\n8x=16.8\n\nx=(16.8)/(8)\n\nx=\$2.1$

Hence, the original price of brownie was $2.1 each.
