Shyam drove to thousand miles in 75 hours at this rate how long will it take her to drive 4000 miles

150 hours

Step-by-step explanation:If she drove 2 thousand miles in 75 hours she will drive 4000 miles in 150 hours because 150 is double of 75 and 4000 is double of 2000. The rate is doubled.

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
