You invest 1000 in an account that pays simple interest rate of 7% for 20 years

if the interest rate is anual, after 20 years the account would have $2400

Explanation:

(interest rate • $$$ invested • amount of time) + $$$ invested = $$$ after total amount of time

(0.07 • 1000 • 20) + 1000 = 2400

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
