Answer:

x = 257/363

Step-by-step explanation:

8x+32=15(25x-15)-4x

8x+32=375x-225-4x

8x+32=371x-225

8x-8x+32+225=371x-8x-225+225

257=363x

$x=\frac{257}{363}$

You are saving money to buy a used car. You deposit $2,500 in an account that earns interest compounded annually. The expression

seraphim [82]

Answer:

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

$A= 2500(1+r)^2$

we can make r subject of formula

$r= [(\frac{A}{P}) ^\frac{1}{t} -1]$

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Hence, for any value of A, we can find the rate using the expression above

Answers with Method:-

1) Multiply the length value by 100,000.

$2.5 \: hm = 2.5 \times 100000$

$= >2.5 \: hm = 250000 \: mm$

2) For this, divide the length value by 1000.

$= > \frac{1800}{1000}$

$= > 1.8 \: dam$

3) For finding the approximate value, just multiply the value of length by 1.609.

$= >6450 \: m = (6450 \times 1.609) \: km$

$= > 10380.27 \: km$

4) Multiply the given mass value by 100.

$= > 1.2 \: kg = 1.2 \times 100$

$= > 1200 \: g$

5) Multiply the given value by 10,000.

$4.37 \: dag = 4.37 \times 10000$

$= > 43700 \: mg$

Find the measure of angle A.

Sergeeva-Olga [200]

Ans: The measure of exterior angle i.e angle A is -52⁰.

You meant to say that the measure of an angle A is on exterior angle so let me elaborate it you clearly,

$x + 59 \\ = - 7 + 59 \\= - 52$
