11.5 because all you do is divide the numbers by 2
masya89 [10]3 years ago
4 0

Answer:

11.5

Step-by-step explanation:

x=8 & y=23

then

x=4 is half so you divide by 2

so half of 23 would be 11.5. If you are rounding then it would be 12

JAB Consulting received a promissory note of $13,500 at 7% simple interest for 15 months from one of its customers. After 6 mont
Tasya [4]

Answer:

Amount = $14,024 (Approx)

Step-by-step explanation:

Given:

Amount received P = $13,500

Rate r = 7% = 0.07

Time t = 15 month = 15/12 = 1.25 = year

Discount rate = 6% = 0.06

Computation:

Maturity value = P[1+rt]

Maturity value = 13,500[1+(0.07)(1.25)]

Maturity value = $14,685.61

Time = 15 month - 6 month

Time = 9 month = 9/12 = 0.75 year

Amount = MV[1-dt]

Amount = 14,685.61[1-(0.75)(0.06)]

Amount = $14,024 (Approx)

Solve for x: 3x − 2 > 5x + 10. (5 points)
Galina-37 [17]

Answer:

x < -6

Step-by-step explanation:

3x - 2 > 5x + 10

first step is to isolate x

3x -2 >5x +10

3x > 5x + 10 + 2

3x -5x > 10 + 2

now that we have 3x and -5x we can combine them

-2x > 10 + 2

now add 10 +2 =12

-2x > 12 (now divide by -2)

x < -6 (when we divide we flip the inequality sign)
