The answer should be 225
MaRussiya [10]3 years ago
5 0

Answer:

225

Step-by-step explanation:

Mary = 3x (3 times Carey)

Carey = x

Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)

3x + x + x/2 = 405

4x + x/2 = 405

8x/2 + x/2 (treat these as fractions) = 405

9x/2 = 405

9x = 810 (cross multiply)

x = 90

Mary = 3(90)      270

Carey =              90

Barry = 90/2      45

Mary - Barry

270 - 45 = 225

Hope this helps! :)

How many pieces of wire 3.6cm long can be cut from a coil of 1m long?What is the length of the piece left over?​
sp2606 [1]

Answer:

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over

Step-by-step explanation:

Find the "unit length" by dividing 1 m by 3.6 cm:

  1 m

-----------

3.6 cm

Recall that 1 m = 100 cm.  Multiply the following by the conversion factor 100 cm / 1 m:

  1 m            100 cm

----------- * ----------------- = 27,7777777...

3.6 cm            1 m

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).

97.94 is 83% of what number?
Aleksandr [31]

Answer:

97.94 is 83% of 118

Step-by-step explanation:

Let the missing number be x

97.94=83% of x

I.e, 97.94=83/100 × x

97.94=83x/100

Cross multipy 97.94/1=83x/100

We have, 97.94 × 100 = 83x × 1

9794=83x

Divide both sides by 83 to make x the subject of the formula.

9794/83=83x/83

118=x
