Aclydesdale drinks about 120 gallons of water every 4 days, at this rate, about how many gallons of water will he drink in 28 days

i'm stuck on this question and need to go to school

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

its 4 because 2 times 2 is 4, if you double the number two you get four
