21/7+3/7(3x−5)=−4Drag and drop the statement that shows the solution to the equation into the box.

Answers

Answer 1

Answer:

i know this is really late but its for people here now (like me) the answer would be x= -3 1/9

Answer 2

Answer: 21/7 + 3/7(3x - 5) = -4
21/7 + 9/7x - 15/7 = -4.....multiply everything by 7
21 + 9x - 15 = - 28
9x + 6 = -28
9x = -28 - 6
9x = - 34
x = -34/9 or - 3 7/9

Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0.75p, where p is the original price of the laptop. He also knows he has to pay 8% sale's tax on the laptop. The price of the laptop with tax is f(c) = 1.08c, where c is the sale price of the laptop.Determine the composite function that can be used to calculate the final price of Ray's laptop by solving for f[c(p)]. f[c(p)] = 1.83p f[c(p)] = 1.83cp f[c(p)] = 0.81p f[c(p)] = 0.81cp

Jackie scored 82 and 88 on her first two quizzes. Write and solve a compound inequality to find possible values for a third quiz score that would give her an average between 80 and 85, inclusive.a. 80 <= 82 + 88 + n / 3 <= 85; 70 <= n <= 85

b. 70 <= 82 + 88 + n / 3 <= 85; 80 <= n <= 85

c. 80 <= 82 + 88 + n / 3 < 85; 70 < n < 85

d. 82 <= 80 + 85 + n / 3 <= 88; 70 <= n <= 85

Answers

Answer : option A

Jackie scored 82 and 88 on her first two quizzes

Let n be the score of third quiz

Average of 3 quiz = $(82+88+n)/(3)$

average between 80 and 85, inclusive.

so average lies between 80 and 85

Question says 80 and 85 inclusive. so we use <= or >= symbol

So inequality becomes

$80<= (82+88+n)/(3) <= 85$

$80<= (170+n)/(3) <= 85$ ( multiply all sides by 3)

$240<=170+n<= 255$ (subtract all sides by 170)

$70<=+n<= 85$

so option A is correct

the answer is a . first you can understand that b and d can not be the answers because the question says that hey score should be between 80 and 85 so between a and c the answer is a :)))
i hope this is helpful

What comes after 2- on the number line

Answers

Answer:

If you're going to the left, 1, if you're going to the right 3.

If you meant to write -2, then to the left -3 and to the right =-1

-3 -2 -1 0 1 2 3

If you’re going to the left of the number line -3 comes after but if you’re going to the right -1 comes after

Boris Heban is single and pays into an HMO. The total cost is $8,190 annually, and the employer pays 90 percent of the total cost. He also pays 50 percent of the optional annual dental premium of $662 and 50 percent of the optional vision premium of $188. How much is deducted each week from his paycheck?

Answers

so Boris has to pay:
10% * 8190 = 819
50% * 662 = 331
50% * 188 = 94

so in total he pays: 819 + 331 + 94 = 1244

deducted each week is (52 weeks in a year):
1244/52 = 23.92

so each week $23.92 are deducted from his paycheck

The reciprocal of of 1 over 5

Answers

The reciprocal of 1/5 is: 5/1 or just 5.

To get the reciprocal of a fraction, it basically just means to flip the numbers. If you're dealing with a whole number (such as 5 in this case), you would divide 1 by the number, making it 1/5.

The product of a + 3 and –2a2 + 15a + 6 is –2a3 + xa2 + 51a + 18. What is the value of x?A=3
B=9
C=12
D=15

Answers

(A+3) x ( -2A2+15A+6) = (-2A3+XA2+51A+18)
(3+3) x ( -2*3*2+15*3+6) = (-2*3*3+X *3*2+51*3+18)
(6) x (-2*3*2=-12 + 15*3=45 +6 = 51
(6) x (-12 +51=39)
6 x 39 =( -2*3*3= -18)+ x *3*2+(51*3+18=171)
6 x 39 -18 + x*3*2+ 171
6 x 39 =234
234 -171=63
-18 + 5x=63
X = 13.5
