<h2>○=> <u>Correct option</u> :</h2>

\color{plum}\tt\bold{(D)  \: 17}

<h3>○=> <u>Steps to derive correct answer</u> :</h3>

Given :

▪︎Angle (5x)° and angle 95° are supplementary angles.

Which means :

= \tt5x + 95 = 180

= \tt5x = 180 - 95

= \tt5x  = 85

\hookrightarrow\tt \color{plum}x  = 17

Thus, the value of x = 17

Let us check whether or not we have found out the correct value of x by placing 17 in the place of x:

=\tt5 \times 17 + 95 = 180

=\tt 85 + 95 = 180

=\tt 180 = 180

Since the sum of both angles is equivalent to 180[85+95=180], we can conclude that we have found out the correct value of x.

Therefore, the correct option is (D) 17

Find the greatest common factor 28 and 12<br><br> use the GCF to factor 28+12.
fgiga [73]

Answer:

(a) 4

(b) 4 * (7+3)

Step-by-step explanation:

(a) Let's first start by prime factorizing (finding the prime factors) 28 and 12:

12: 2*2*3

28: 2*2*7

We can see here they both share a common factor of 2*2, which is 4, therefore the GCF is 4.

(b) Factor a 4 out from the equation:

4*(\frac{28}{4}+\frac{12}{4})

This gives us:

4 * (7+3)

In a particular class, exams are worth 50% of the overall grade, quizzes are worth 30% of the overall grade, homework is worth 1
Paha777 [63]

Answer:

The student's overall grade is 85.79%

Step-by-step explanation:

Given in the question that:

Exam = 50%; Quiz = 30%, Home work = 15% and Class participation = 5%

The total giving us 100%.

A particular student scored the following;

87.9% on exams, 77.8% quiz, 90% Home work and 100%  on class participation

Calculating the percentages the student had for each;

Exam total = 50*0.879 = 43.95% earned

Quiz = 30*0.778 = 23.34% earned

Home work = 15*0.9 = 13.5% earned

Class participation = 5*1 = 5% earned

Total earned = 43.95+ 23.34 + 13.5+ 5 = 85.79%

I need help on this question
Doss [256]
Hi,
Following the rules of PEMDAS you first subtract in the parentheses. 
(5-2)=3
Then multiply the parentheses.
(3)(-6)=-18
Solve the exponent.
-4^2=16
Then you add -18 and 16 to get -2. 
So the answer is B.-2.
I hope this helps.

PLEASE HELP I’M SO CONFUSED
bekas [8.4K]

Answer:

a. $45 an hour

b. 5.25 hours

Step-by-step explanation:

a. The plumber charges $75 per job, so it is irrelevant to the number of hours they work. 45(h) is $45 multiplied by the number of hours they work.

b.

First, plug the numbers into the equation, the cost being C(h):

311.25 = 45(h) + 75

Next, subtract $75 as it is a set price that is always payed:

236.25 = 45(h)

Then, divide both sides by 45 to find how many hours were worked:

h = 5.25

Hours = $5.25
