The way to solve is using order of operation PEMDAS. Its very easy. You should be able to solve it yourself. I'll give you the first 3 answers:
1. g/6=x
2. x=1/2u+1
3. z-m=x
I would give you all the answers but it would be best if you did it yourself. You teacher and parents would be much happier if you learnt the skill. Hope this answer helps! Mark as brainliest! :)

Use properties of multiplication to show why 4 x 50 = 8 x 25.

nikdorinn [45]

Given:

$4\times 50 =8\times 25$

To find:

The steps to prove the given statement by using the properties of multiplication.

Solution:

We have,

$4\times 50 =8\times 25$

Taking left hand side, we get

$LHS=4\times 50$

$LHS=4\times (2\times 25)$

$LHS=(4\times 2)\times 25$ (Associative property of multiplication)

$LHS=8\times 25$

$LHS=RHS$

Hence proved.

John took all his money from his savings account. He spent $110 on a radio and 4/11 of what was left on presents for his friend

svp [43]

Answer:

$1210

Step-by-step explanation:

Let x be total amount

First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with

$\frac{7}{11}(x-110)=\frac{7}{11}x-70$

Then he put 2/5 of his remaining money into a checking account

$\frac{3}{5}\left(\frac{7}{11}x-70\right)$

Rest he donated to charity

$420=\frac{3}{5}\left(\frac{7}{11}x-70\right)\\\Rightarrow \left(\frac{7}{11}x-70\right)=\frac{2100}{3}\\\Rightarrow \frac{7}{11}x-70=700\\\Rightarrow \frac{7}{11}x=770\\\Rightarrow x=1210$

Hence total amount of money John originally had was $1210
