Pls Help I Asked 2 Time So Far And No One I Need Help I Will Mark Brainliest

Answers

Answer 1

Answer:

x = 33

Step-by-step explanation:

This picture shows a supplementary angle which means:

angle 1 + angle 2 = 180°

In order to solve for x, you need to add both the angles

(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms

6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°

6x = 198 now divide 6 by 162

x = 33

Answer 2
X=27 please mark me brainliest thanks :D

The number of pages that Allen, Kevin, Roneisha, and Ben can read in a day is shown below. Allen read 15% of his 56-page book. Kevin read 12% of his 64-page book. Roneisha read 16% of his 42-page book. Ben read 10% of his 72-page book. Who can read the greatest number of pages in a day?

Group of answer choices:

Kevin

Allen

Roneisha

Ben

Answers

It would be “Allen” since his percentage is far more grater then the rest, even Roneisha because even though her percentage is 1% greater, she has less pages, Ben has more pages but has 1% less.

A bicycle has a listed price of $544.98 before tax. If the sales tax rate is 9.75%, find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

$598.12.

Step-by-step explanation:

First you need to make the percent into a decimal and multiply it by the price without tax: 0.0975 · 544.98, which equals 53.136 when rounded to the nearest thousandth. This means that 53.136 is 9.75% of 544.98. Then you just need to add 53.136, or 53.14 when rounded, to 544.98. This gives you $598.12.

Answer:

  8x·x·x·x·x·x

Step-by-step explanation:

Using the rules of exponents, this simplifies to ...

  [tex](2x^2)^3 = 2^3x^{2\cdot3}=8x^6=\boxed{8\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}[/tex]

__

The applicable rules of exponents are ...

  (a^b)^c = a^(bc)

  (ab)^c = (a^c)(b^c)

Of course, an exponent signifies repeated multiplication.

Answer: X would equal -8

Step-by-step explanation: Starting off, you would cross multiply, so 414 times 1 = (x-10) times -23. It's similar to the one I answered before, just with different numbers. 414 = -23 (x-10). After that, distribute to get: 414 = -23x +230. Then subtract 230 from both sides and divide by -23 to get x. Hope that helps.
