The crocodile grows 1/5 the length he was the last week. 

SO, you need to find a number that will ensure that the end result is 30.

What number plus 1/5 of it equals 30?

25. 

25/5= 5

25+5= 30

So, the number is 25. The crocodile was 25 cm long last week.

I hope this helps!

Priya has a recipe for banana bread. She uses 7 1/2 cups of flour to make 3 loaves of
Umnica [9.8K]

Answer:

2 1/2 cups of flour

Step-by-step explanation:

Priya is making 3 loaves of bread, so she will use 7 1/2 cups of flour.

Andre is making 1 loaf of bread, which is 1/3 the amount of loaves Priya is making. So, he will be using 1/3 the amount of flour Priya is using. So all we have to do is take 7 1/2 and divide it by 3:

7.5/3 = 2.5

Andre will use 2 1/2 cups of flour.

Solve 4 + 4 ( x - 2 ) = 2 ( x + 1 ) - x<br> The question requires you to show your work
kati45 [8]

Answer:

x = 2

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 (4+(4•(x-2)))-(2•(x+1)-x)  = 0

Step  2  :

Equation at the end of step  2  :

 (4 +  4 • (x - 2)) -  (x + 2)  = 0

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  3x - 6  =   3 • (x - 2)

Equation at the end of step  4  :

 3 • (x - 2)  = 0

Step  5  :

Equations which are never true :

5.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2      Solve  :    x-2 = 0

Add  2  to both sides of the equation :

                     x = 2

One solution was found :

                  x = 2

What is the average of 63 and 148
fgiga [73]

The average is 105.5. To find the average, you have to add up all numbers, 63+148=211. Now you have to divide by how many numbers there are,               211÷2=105.5

p varies directly as q and inversely as r. One set of values is p = 5, q = 1, and r = 2. Find p when q = 10 and r = 50.
kari74 [83]
P = kq/r

5 = k*1/2
k = 2*5 = 10

p = 5*10/50 = 1
P is 1.

Hope it helps!
