Answer:

x\y=5\3. ..........[I]

X=5y\3

X+y=56

X=56-y.........[ii]

substitute [I] &[ii]

5y\3=56-y

5y=3[56-y]

5y=168-3y

5y-3y=168

2y=168

y=168\2

y=84........[iii]

substitute [iii] in [ii]

X=56-84

X=-28

x-y=-28-84

=-112

Find a direct relationship between x and y. x = 3t and y = 2t + 7

ikadub [295]

Answer:

y = $\frac{2}{3}$ x + 7

Step-by-step explanation:

Given

x = 3t ( divide both sides by 3 )

$\frac{1}{3}$ x = t

Substitute this value into y = 2t + 7

y = 2 × $\frac{1}{3}$ x + 7 = $\frac{2}{3}$ x + 7

A 10-year annuity pays $1,850 per month, and payments are made at the end of each month. If the APR is 12 percent compounded mon

Fittoniya [83]

Based on the amount the annuity pays per month and the APR, the value of the annuity today is $133,349.85.

<h3>What is the present value of the annuity?</h3>

First, find the present value of the annuity at 5 years:

= 1,850 x present value interest factor of annuity, 60 months, 8/12%

= 1,850 x 49.32

= $91,242

Then find the present value of the annuity from 5 years till date:

= (1,850 x present value interest factor of annuity, 60 months, 12/12%) + ( 91,242) / (1 + 1%)⁶⁰)

= (1,850 x 44.955) + ( 91,242) / (1 + 1%)⁶⁰)

= $133,349.85
