ST=<br> Help me please thank u
dmitriy555 [2]

Step-by-step explanation:

RS + ST = 8

(RS + ST)×RS = (4 + 2)×4

8 × RS = (4 + 2) × 4 = 6 × 4 = 24

RS = 24/8 = 3

RS + ST = 8

3 + ST = 8

ST = 5

Sonya took out a mortgage of $65,000 at 7% for 25 years. What is the cost of the mortgage?
Vika [28.1K]

The cost of the mortgage is $81250

<h3>What are interests?</h3>


Interests are percentages of a principal

Given the following parameters

Principal = $65000

Rate = 7% = 0.07
Time = 5 years

<h3>Calculate the interest</h3>

I = PRT/100
I = 65000*0.07*25
I = 16,250

<h3>Determine the cost of the mortgage</h3>

Cost of mortgage = Principal + Interest

Cost of mortgage = 65000 + 16250
Cost of mortgage = 81,250

Hence the cost of the mortgage is $81250

three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally
Flura [38]
28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86  now we gonna find the value of x.
 28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x. 
28x≤114 divide 28 both of side to get value of x so it will be x≤4
