Answer:
I need this question 2!
Step-by-step explanation: can someone please answer this.
Step-by-step explanation:
-3x+2y=-10
-2(-2x+y=-6)
-3x+2y=-10
4x-2y=12
-3x=-10
4x=12
x=2
When both the measures are in the same units, then the ratio can be calculated.
1 hour = 60 minutes
⇒ 2 hours = 2 x 60 minutes
= 120 minutes
The ratio of 50 minutes to 2 hours is then:
50 : 120
⇒ 5 : 12
Answer:-150t-110
Step-by-step explanation:
-10(5t+5)-10(10t+6)
-50t - 50 - 100t - 60
=
-150t-110
