The sum of two numbers is 67. The larger number is 4 more than 2 times the smaller. What are the two numbers?a) 23 and 44
b) 21 and 46
c) 19 and 48
d) 17 and 50

Answers

x,y - two numbers (x > y)

(1) x + y = 67 ⇒ x = 67 - y
(2) x - 4 = 2y

subtitute (1) to (2)

67 - y - 4 = 2y
63 - y = 2y |add y to both sides
63 = 3y |divide both sides by 3
y = 21

subtitute the value of y to (1)

x = 67 - 21 = 46

Answer: 21 and 46.

Marilyn has two credit cards, D and E. Card D has a balance of $691.64, and Card E has a balance of $1,014.22. The minimum monthly payment on Card D is 3.57% of the total balance, and the minimum monthly payment on Card E is 2.51% of the total balance. How much greater is the minimum payment on Card E than on Card D? a. $18.85 b. $8.10 c. $11.24 d. $0.77

Answers

Answer:

D. $ 0.77

Step-by-step explanation:

Given,

In card D,

Balance = $ 691.64,

Percentage of minimum monthly payment = 3.57%,

Thus, the minimum payment = 3.57% of 691.64

$=(3.57* 691.64)/(100)$

$=(2469.1548)/(100)$

≈ $ 24.69,

In card E,

Balance = $ 1,014.22,

Percentage of minimum monthly payment = 2.51%,

Thus, the minimum payment = 2.51% of 1014.22

$=(2.51* 1014.22)/(100)$

$=(2545.6922)/(100)$

≈ $ 25.46,

∵ Minimum payment in card E > Minimum balance in card D,

Thus, the difference between minimum balance in card E and minimum balance in D = 25.46 - 24.69 = $ 0.77

Hence, OPTION D is correct.

the answer is D-$0.77, i need 20 characters for this to be answer so this is all extra.

Help me find y........

Answers

Answer:

Step-by-step explanation:

the sum of all angles in a quadrilateral must be 360º

y+88+25+35 = 360

y = 360=88-25-35

y = 212º

the sum of all angles in an octagon must be 1080º

45+45+140+140+6y = 1080

6y = 1080-90-280

6y = 710

y = 710/6

y=~ 118,3º
