Answer:
27
Step-by-step explanation:
here we remark that we have a proportional relationship Between the number of seeds and the number of flowers
Let x be the number of seeds we need in order to guarantee that 45 flowers grow.
8 seeds ————————-> 5 flowers
x seeds ————————-> 45 flowers
in order to find x ,We have to solve this equation :
⇔ x/8 = 9
⇔ x = 8×9 = 72
“how many seeds did not grow” : 72 - 45 = 27
Answer:
15/14
Step-by-step explanation:
I am assuming you meant. 3(x+1/2)
10x-6=3x+3/2
7x=3/2+12/2
7x=15/2
x=15/2*1/7
x=15/14

y
over the change in

, or rise over run.
The change in
x
x
is equal to the difference in x-coordinates (also called run), and the change in
y
y
is equal to the difference in y-coordinates (also called rise).
Substitute in the values of

Answer:
see the explanation
Step-by-step explanation:
we have
0.888...
This is a <u>repeating decimal</u> (Is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending)
Convert to fraction number
Let
x=0.888...
10x=8.888...
Subtract 0.888... from 8.888... to remove the decimal
10x-x=8.888...-0.888...
9x=8
Solve for x
x=8/9
therefore
Mike fraction is incorrect
because 4/5=0.8
0.8 is a <u>terminating decimal </u>(It's a decimal with a finite number of digits)
Mike's mistake was considering the number as a terminating decimal instead of a repeating decimal
Beth is correct
because
If you divide 8/9
the result is 0.8888888...
