Pls Help Im Very Confused On This

Answers

Answer 1

Answer:

2nd Line

Step-by-step explanation:

In the second line he multiplied out the -4 and -8 which should've been a positive 32 but he put it as a negative.

Answer 2

Answer:

x = 7 ; see explanation below :)

Step-by-step explanation:

First off, here's what the steps should've actually been:

[tex]-4(x-8)+2x=18\\-4x+32+2x=18\\-2x+32=18\\-2x=-14\\x=7[/tex]

Now, the mistake in the original equation is that -4(x-8) was expanded to be -4x-32 - It is not '-32' because multiplying two negative numbers (-4 and -8)  will give you a positive number - that number should be 32. Of course, that one silly mistake then made the rest of the equation wrong too!

Angle bisectors

Bisectors are lines that divide an angle into two equal parts. If RS is the segment bisector and given the following parameters:

OQ = 32

PO = 4x,

This shows that OQ = PO that is:

32 = 4x

Swap

4x = 32
x = 8

Hence the value of x of OQ is equal to PO is 8

A person picks 250 apples an hour and works for 5 hours a day. How many apples can be picked in 2 weeks, assuming apples are picked each day??

Answers

Woah picking apples seems like a fun job…very fun…anyway…
So this person picks 250 apples in 1 hour and works 5 hours a day. Do 250 times 5 because he will be picking apples for 5 hours a day. 250x5=1,250 apples. This person picks 1,250 apples a day. So the question asks how many apples can be picked in two weeks if this person picks apples everyday. We all know there are 7 days a week, so if it’s 2 weeks, then 7x2=14 days in 2 weeks. Now we take that 1,250 (number of apples this person picks a day) and times it by 14 (days this person will be picking apples). 1,250x14=17,500 apples. 17,500 apples can be picked in 2 weeks.

Answer:

17,500 Apples in 2 weeks

Step-by-step explanation:

250 apples*5 hours*14 days= 17,500 Apples in 2 weeks

Which of the following is an irrational number? How do you know? Use key words and definitions to explain your answer choice.
1632
0.25
0.0300300030000…
0

Answers

Answer:

0.0300300030000...

Step-by-step explanation:

An irrational number has endless non-repeating digits to the right of the decimal point. They can be written as decimals, but not as fractions.

1632 can be written as 3264/2

0.25 can be written as 1/4

0 could be written as 0/0

but 0.0300300030000 cannot be written as a fraction, and it satisfies the condition of an irrational number having endless non-repeating digits to the right of the decimal point.

(b) Four of the interior angles of a 12 sided polygon are each x °. The other angles are 2xº each. Calculate the value of x.​

Answers

Answer:

Step-by-step explanation:

Sum of all the angles of 12 sided polygon= (n -2)*180

   = (12 - 2 )*180 = 10 * 180 = 1800

Four interior angle each of xº +  8 interior angles each of 2xº = 1800

4*x  + 8*2x = 1800

4x + 16x = 1800

20x = 1800

x = 1800/20

x = 90°

Answer:

x = 90

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 12 , then

sum = 180° × 10 = 1800

There are 12 interior angles

Given 4 are x, then 8 are 2x , so

4x + 8(2x) = 1800

4x + 16x = 1800

20x = 1800 ( divide both sides by 20 )

x = 90

Answers

Answer:

1_ 129 , 51

2_ b

3_ 40

Step-by-step explanation:

1_ we can represent the bigger angle with x and smaller one with y

and as given, y is smaller than x by 78

so y = x - 78 (1)

as x + y = 180

we put y as we did in (1)

x + x - 78 = 180

so 2x = 258

so x = 129

and y will be 51

2_ from the figure we find the two angles form one angle = 90 degree

3_ from the defenition of complementary angles

m(c) + m(d) = 90

7r + 5 + 8r + 10 = 90

15r + 15 = 90

r = 5

so m(c) will be equal 7*5 + 5 = 40

Ms. Jacobs is a photographer. For each job she charges $135 for the first hour she works and $100 for each additional hour. Ms. Jacobs charged a total of $535 for a job on Friday. Which equation can be used to determine h, the number of additional hours she worked on this job? MI - A 135h + 100 = 535 B 135 + h + 100 = 535 SI - C 135 + 100h = 535 PSA - D 135h = 535 + 100 is​

Answers

Answer:

The answer is C, 135 + 100h = 535.

Step-by-step explanation:

H can't be multiplied by 135, since that's only for one hour.  That value never changes, so it can't be A.  It's not B because that implies that she starts out by charging $235 for the first hour, plus the # of additional hours, which doesn't make sense.  And it's not D because the total amount of $ that she receives must EQUAL 535, but there is another number on the same side with 535.  Therefore, the only answer that remains is C.  

P.S. She worked 4 additional hours.
