How many periods of time , each 1/4 of an hour long does a 10-hour period of time represent. help me​

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

i belive those are the ones that are under 90 degreese.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3

=

−37

−3

x=

37

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
