Answer:
5x+2
Step-by-step explanation:
6x-x=5x and 5-3=2
so 5x+2 is the answer.
Answer:
x=18
QR=29
RS=29
QS=29
Step-by-step explanation: 2X-7=5x-61=x+11 solve for x since all sides are equal
For an exponential distribution, the standard deviation is equal to the mean.
(a) the standard deviation is 4 miles.
Answer:
We know that:
She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)
She only has 1/3 of the amount she needs.
How much flour does she have?
Well, she needs 9/10 grams, and she has one-third of that.
Then she has (1/3) times (9/10) grams, this is:
F = (1/3)*(9/10) grams
F = (1*9)/(3*10) grams
F = 9/30 grams
That is the amount of flour that she has.
First you multiply how much they make per hour by the number of hours they worked that weren’t overtime. So you would multiply 4.9 and 40.
4.9(40)=$196
Then you multiply 7.35 and the number of hours worked overtime. To find the number of hours worked overtime you would subtract 40 from 46.
46-40=6
Now you multiply again.
7.35(6)=$44.10
Then you add the two amounts made together.
196+44.10=$240.10
The student makes $240.10.
