Write 720,000 in expanded form with an exponent

split the number into 700,000 and 20,000

700, 000 = 7*10^5

20,000= 2.*10^4

 so you end up with 7*10^5 + 2*10^4

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

yes because they have the same amount of green and blur marbles.
