Answer:
With Riley's pattern, he will practice 2,000 total minutes in 25 days.
Step-by-step explanation:
Since Riley increased his practice time by 20, 20 times 40 is 80 minutes. And since he is repeating this in total of 25 days, 80 times 25 is 2,000.
Hope this helped you in some way. If not, then let me know.
Answer: honestly for the first one, i think the answer would be 2.
they both have 5 at the end so you know its divisible :)
Step-by-step explanation:
Answer:
A=z
B=-2
C=0
D=30
Step-by-step explanation:
First lets simply the equation
21 - (2x +3)2 + 4(1-1) + z^3
21 - (2x^2 + 9) + 4(0) + z ^3
21 - 2x^2 + 9 + z^3
- 2x^2 + z ^3 + 30
This means that:
A=z
B=-2
C=0
D=30
Are you wanting to solve for x? If so:
4x + 7 = 35
We want to isolate the variable, so subtract 7 from both sides. You will get:
4x = 28
Now, divide each side by 4 to get X by alone. This will give you:
x = 7
I hope this helped.
