Answer:
It would take 4 weeks
Step-by-step explanation:
We can solve this problem most easily by forming it into an equation. We could represent weeks as <em>w.</em>
Since you train 5 more minutes every week, we could represent that as 5<em>w</em>, showing that you work 5 minutes times the number of weeks you worked out.
The constant would be adding 10, since you started out working 10 minutes a day. Now lets just write the equation!
10+5<em>w</em>=30
All we have to do is solve.
Subtract 10 on both sides to cancel out the positive 10.
5<em>w</em>=20
Now just divide both sides by 5 to isolate the <em>w</em>.
w=4
It would take him 4 weeks
Hope this helps!
Answer:
-1.75 I apologize if that is not right but i am 99% sure
Step-by-step explanation:
When you add like terms on the right side you end up with 2x, then all you di is divide both sides by 2 and you end up with -1.75
Answer:
The number is -1/2.
Step-by-step explanation:
I am assuming they are fractions. So we have the equation:
5/2 x + 2/3 = -7/12
We multiply through by 12 to eliminate the fractions:
5/2 * 12 x + 2/3 * 12 = -7/12 * 12
30x + 8 = -7
30x = -15
x = -15/30
x = -1/2.
I think it’s 6y hopefully it’s correct lol
