Answer from: cardsqueen

make An equation for both of the numbers in the parentheses .

Step-by-step explanation:

this is how it should look x -2 would be x =15, because you add 2 on both sides , now you have x=15 which should be the answer because 15 is now x and 15 minus 2 = 13

now for the second one

first subtract 10 on both sides then you should get the answer X equals three the reason why it’s like that is because 3 is now x and 3 + 10 = 13.

Hope this helped have a good day :D

by definition, an arc subtended by a central angle of some given measure has the same measure. so $(3x+18)^\circ=147^\circ$ .

Answer from: Quest

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
