Julius has three times as many stamps in his collection as his friends Liam has 10 stamps in his collection. Julius has 87 stamps in his collection. How many stamps does Mario have in his collection? The equation 3(x + 10) = 87 models this situation. Which choice shows the sequence of operations needed to solve this problem using both arithmetic and algebra?

i can't solve unless i know what the line is

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
