Answer:
D. 63%
Step-by-step explanation:
the white marble was picked out 41 of the 65 times, so 41/65
divide 41 by 65 in your calculator and you get .6307
then multiply it by 100 because it asked for a percentage and you get 63%
Ta-Da!
No, the system is inconsistent.
Step-by-step explanation:
If the last column is a pivot column, then that row gives an equation that looks something like 0x+0y+0z=1 , meaning , 0=1. Clearly, this is false.
So, the system of linear equations is inconsistent.
Let us say that the procedure of completely filling up the
pool with water is called “1 job”. Therefore the rates of the equipment in
doing the job would be:
<span>Rate of handheld hose = 1 job / 8 minutes ---> 1</span>
<span>Rate of lawn sprinkler = r --->
2</span>
<span>Rate of the two combines = 1 job/ 5 minutes ---> 3</span>
So we are to find the equation to use, in this case, we
simply have to add equations 1 and 2 to get 3:
1 / 8 + r = 1 / 5
Multiplying both sides by 5:
<span>(5 / 8) + 5 r = 1 --->

Answer:
-14/15-1/15v
Step-by-step explanation:
First you make all of the fractions have the common denominator 15.
And then you have -18/15-6/15v+4/15+5/15v
Then you combine like terms to get -14/15-1/15v
Answer:
1. V = D/t => D=Vt. as V = 16mph
D = 16t
2. Prya has been riding for t+½ hours
3. Prya has gone 12(t+½) miles
4. When Prya and Han meet
16t = 12t +6
4t = 6
t = 3/2 hours
