Suppose Lindsay’s mom invests $10,000, part at 3%, and the rest at 2.5%, in interest-bearing accounts.-10,00007.5 The totally yearly investment income (interest) is $283. How much did Lindsay’s mom invest at each rate?

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

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
