Answer:
acute
Step-by-step explanation:

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on
so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)
thus (0.30x) + (175)(0.65) = (x+175)(0.50)
solve for "x"
The answer is A!
Sadie is correct because 3(2x+3y) equals 6x+9y
