For which values of P and Q does the following equation have Infinity many solutions? P×+57=-75x+Q

Semenov [28]

earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

p*x+57-(-75*x+q)=0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Unless there is none then in that case there very well may be infinite solutions

Misha increased her test score from 60% to 80%.. What was the approximate percent increase of Misha's test score?. 25%. 33%. 66%

Anvisha [2.4K]

we know that

Using the original score as the basis

If Misha increased her test score from $60$ % to $80$ %

then

the increase variation is equal to

$80$ %- $60$ %= $20$ %

to find the approximate percent increase of Misha's test score we apply a rule of three

if $60$ %--------------> represents $100$ %

$20$ %----------------->x

$x=20*100/60$

$x=33.33$ %

therefore

the answer is

the approximate percent increase of Misha's test score is $33$ %

Swim team members can race or dive. At a meet, 18 members race. The ratio of racers to divers is 6 : 2. How many members are on

AnnyKZ [126]

Answer:

Step-by-step explanation:

Given that:

Total number of members who race = 18

Ratio of racers to divers = 6 : 2

To find:

Total number of members of the team = ?

Solution:

Given the ratio = 6 : 2

As per the ratio given, we can let the number of racers = $6x$

and

As per the ratio given, we can let the number of divers = $2x$

As the swim team members can either race or dive, we can say that:

Total number of members on the team = Number of racers + Number of divers

Total number of members on the team = $6x+2x=8x$

As per the question statement, we are given that:

$6x=18\\\Rightarrow x =\dfrac{18}{6}\\\Rightarrow x =3$

Therefore, total number of team members = 8 $\times$ 3 = <em>24</em>
