Answer:
25,26,27, and 28
Step-by-step explanation:
Write consecutive integers as x,x+1,x+2,x+3,x+4, and so forth.
x+x+1+x+2+x+3
---------------------- = 53
2
1) Combine alike terms:
4x+6
------- = 53
2
2) Multiply both sides by 2:
4x+6=106
3) Subtract 6 from both sides:
4x=100
4) Divide both sides by 4:
x=25
5) Plug in 25 for x for all 4 integers:
25
26
27
28
Answer:
Step-by-step explanation:
Notice that:
● 1/2 = 0.5
● 4/5 = 0.8
0.8 is greater than 0.5.
So:
● 0.8 > 0.5
● 4/5 > 1/2
Answer:
The answer is b. 4*3 2/5.
Step-by-step explanation:
It states 4 times the amount Ruby mixed. Ruby mixed it 3 2/5 solution. So you would right out 4 x 3 2/5.
Answer: The first day the author reaches 100 days is on day 16.
To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.
You could use the quadratic equation to solve: 100 = x^2 -12x + 45
Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
