2x-10=44+8x
Subtract 2x from both sides
-10=44+6x
Subtract 44 from both sides
-54=6x
Divide 6 on both sides
Final Answer: x= -9
Answer:
d) 1.25 g
Step-by-step explanation:
If it has a half life of 40 days, there will be 5 half-lives in that span of time so if you divide 40 by 2, 5 times or just , it will equal 1.25.
Answer:
b = 10
b = 17
Step-by-step explanation:
Hello!
Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.
So what we want to know is that b should be the sum of the factors in 16.
Factors of 16: 1, 2, 4, 8, 16
Factor pairs:
Factor Sums:
These are our possible b-values.
Check:
Let's try 17 first:
- x² - 17x + 16 = 0
- (x - 16)(x - 1) = 0
- x = 16, x = 1
Now 10:
- x² - 10x + 16 = 0
- (x - 8)(x - 2) = 0
- x = 8, x = 2
And finally, 8:
- x² - 8x + 16 = 0
- (x - 4)(x - 4) = 0
- x = 4, x = 4
Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.
The answers are b = 10, and b = 17.
She is 78 because you have to find what 7 goes into and what number is one more than that number has to be a multiple of 6
Answer:
25x + 5y + z cents
Step-by-step explanation:
1 quarter is worth 25 cents.
1 nickel is worth 5 cents.
1 penny is worth 1 cent.
Therefore, x quarters, y nickels and x pennies will be worth:
(x * 25) + (y * 5) + (z * 1)
= 25x + 5y + z cents
