Answer:
the eq of line is y=2.5x-5
substitute coordinates
y=ax+b
2=2.5(0)+b
then you get b= -5.
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
Can you show us all the graphs
Answer:
13
Step-by-step explanation:
Take this one step at a time
- 1/10 of 3000 = 3000/10 = 300
- 1/10 of 300 = 300 / 10 = 30
- 1/10 of 30 = 30/10 = 3
- So she is 10 more than this which is 13.
- Sora is 13
You can do this another way.
- Age = (1/10)*(1/10)(1/10) * 3000 + 10
- Age = 1/1000 * 3000 + 10
- Age = 3 + 10
- Age = 13
Answer:
y = -13
Step-by-step explanation:
5y + 2(y - 2) = 8y - 3(7 - 10)
5y + 2y - 4 = 8y - 21 + 30
7y - 4 = 8y + 9
-4 = y + 9
-13 = y
y = -13
