Gg easy
divide both sides by 2
t+1=5
minus 1 both sides
t=4
X=1
because you would add two to the other side and have 2x=2 divide by 2 and you would be left with x=1
6:8 = 3:4, 12:16, 18:24
24:18 = 4:3, 8:6, 12:9
15:10 = 3:2, 30:20, 45:30
Answer:
You would solve this as if the inequality sign was an equal sign.
Just make sure when you divide by a negative or multiply by a negative the sign switches, anyways:
5 + 5(x +4) < 20
Distribute the 5 and simplify
5 + 5x + 20 < 20
25 + 5x < 20
Isolate x (subtract 25 from both sides)
5x < -5
Divide by 5
x < -1
Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
