A) fifth = 5/5 (this is a fraction) 1/5 is 1 fifth of 1. Get what i'm saying? So then the will be 5 fifths in a whole

B) ok turn 2 1/3 into a improper fraction and that will be 7/3

C) ok so 4 (a whole number) is 20/5 so you divide 20/5 with 2/5 (ignore this if you don't know what i'm talking about this is in middle school) so that will = 10

Step-by-step explanation:

from what I can see there are 2 options to make the 2 triangles congruent :

either the opposite sides must be equal or the neighboring sides must be equal.

so, either

5x = 3x + 10

and

5x - 2 = 4x + 3

5x = 4x + 3

and

5x - 2 = 3x + 10

for the first

5x = 3x + 10

2x = 10

x = 5

control

5x - 2 = 4w + 3

5×5 - 2 = 4×5 + 3

23 = 23

correct.

for the second

5x = 4x + 3

x = 3

control

5×3 - 2 = 3×3 + 10

15 - 2 = 9 + 10

13 = 19

no, not a valid solution.

so, x = 5

Equation with a slope of -2 and point of (4,7)

s344n2d4d5 [400]

Answer:

y=-2x+15

Step-by-step explanation:

So first we can write it in point slope form.

That is y-y1=m(x-x1)

y1 is the y coordinate

m is the lope

x1 is the x coordinate

This means that the equation is:

y-7=-2(x-4)

We can then convert it to slope intercept form which is

y=mx+b

y-7=-2x+8

y=-2x+15

Enos took out a 25-year loan for $135,000 at an APR of 6.0%, compounded monthly, and he is making monthly payments of $869.81. W

Alborosie

Present value = 135000
Monthly interest, i = 0.06/12 = 0.005
Monthly payment, A= 869.81

Future value of loan after 16 years
$F=P(1+i)^n$ [compound interest formula]
$=135000(1+.005)^{16*12}$
$=351736.652$

Future value of payments after 16 years
$\frac{A((1+i)^n-1)}{i}$
$=\frac{869.81((1+0.005)^{16*12}-1)}{0.005}$
$=279287.456$

Balance = future value of loan - future value of payments
=351736.652-279288.456
= $ 72448.20

Note: the exact monthly payment for a 25-year mortgage is
$A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}$
$=\frac{135000(0.005*(1+0.005)^{25*12}}{(1+0.005)^{25*12}-1}$
$=869.806892$

Repeating the previous calculation with this "exact" monthly payment gives
Balance = 72448.197, very close to one of the choices.

So we conclude that the exact value obtained above differs from the answer choices is due to the precision (or lack of it) of the provided data.

The closest choice is therefore $72,449.19
