2/3 of a some of money is 48p. What is 5/8 of the sum of money?

Answers

Answer 1

Answer: Let the sum of money be x
so 2/3 of x = 48p
so x = 48*3/2 = 72p
so 5/8 of the sum of money = 5/8*72 = 45p

Divide r+5/ r^2+5r-14 by r^2+4-21/r-2

Answers

So we want to divide $(r+5)/(r^2+5r-14)$ by $(r^2+4r-21)/(r-2)$ .
The first thing we are going to do is factor the denominator of the first fraction and the denominator of the second one:
- For our first fraction:
$r^2+5r-14=(r+7)(r-2)$
Now we can rewrite our first fraction:
$(r+5)/(r^2+5r-14) = (r+5)/((r+7)(r-2))$
- For our second fraction:
$r^2+4r-21=(r+7)(r-3)$
Now we can rewrite our second fraction:
$(r^2+4r-21)/(r-2) = ((r+7)(r-3))/(r-2)$

Last but not least, we can express our division as a fraction and simplify:
$((r+5)/((r+7)(r-2)))/( ((r+7)(r-3))/(r-2)) = ((r+5)(r-2))/((r+7)(r-2)(r+7)(r-3)) = (r+5)/((r+7)^2(r-3))$

We can conclude that the result of dividing r+5/ r^2+5r-14 by r^2+4r-21/r-2 is: $(r+5)/((r+7)^2(r-3))$

The graph of the linear equation 3x + 5y
= 15 cuts the x-axis at the point ________.

Answers

Answer:

(0,5)

Step-by-step explanation:

3x-5y=15

Plug in 0 for y, because we are trying to find the value of x, when y is 0

so, 3x-5(0)=15

3x=15 Divide both sides by 3

x=5

so the answer in coordinate form is (0,5)

The answer is A.80.3
equation to use is C=cos^-1 [a^2+B^2+-2^2 /2ab
A=21
B=33
C=36
21^2+33^2-36^2
21^2=441
33^2=1089
36^2=1296
441+1089=1530
1530-1296=234
234/2=117
cos^-1*117=80.28
rounded gives you 80.3, hope this helps :D

3 less than the quotient of 20 and x

Answers

The word 'quotient' tells you that the two numbers will be divided. So, the quotient of 20 and x is $(20)/(x)$ . The phrase 'less than' means you're taking the first number (3) away from the second number ( $(20)/(x)$ ). So, 3 less than the quotient of 20 and x is $(20)/(x)$ - 3 .

"3 less than" would be after the quotient of 20 and x."Less than" means subtraction. "quotient" means division .
So,the expression would have to be: (20÷3)-3
In other terms "twenty divided by three minus three." Any questions?
