In tennis, a first serve can be an ace, a fault, or it can be returned. In one match, a tennis player hit 24 aces, which was 25

Anastaziya [24]

Answer:

16 faults

Step-by-step explanation:

The correct question is

In tennis, a first serve can be an ace, a fault, or it can be returned. In one match, a tennis player hit 24 aces, which was 2/5 of all her first serves. If 1/3 of her first serves were returned, how many of the tennis player's first serves were faults?

Let

x -----> the number of all her first servers

y ----> the number of first services returned

z ---> the number of first services faults

we know that

The number of aces plus the number of returned plus the number of faults must be equal to the number of all her first services

$x=24+y+z$

step 1

Find out the number of all her first servers

we have that

$24=\frac{2}{5}x$

Solve for x

$x=24(5)/2\\x=60\ first\ services$

step 2

Find out the number of first services returned

$y=\frac{1}{3}x$

substitute the value of x

$y=\frac{1}{3}(60)=20\ returned$

step 3

Find out the number of first services faults

$x=24+y+z$

we have

$x=60\\y=20$

substitute and solve for z

$60=24+20+z$

$60=44+z$

$z=16\ faults$

lennys lizard weighs 6 pound less than duble the laura's lizard lennys weighs 60 pounds find the weight of lauras lizard

Butoxors [25]

(Me, going to answer the easy questions because hard ones give me headaches)

Alright, listen up.

Steps:

First step: 60 is Lenny's lizard weight. Since it said 6 pounds less than double the lizard weight, we are going to multiply 60 by 2, therefore it would be 120.

Next step: Now 6 pounds less, so we are going to subtract 6 from that 120. 120 - 6 = 114.

Last step...: Label/answer: Lenny's lizard weight is 114 pounds.
