mrs jones gave 1/5 of a cake to her neighbour. she then sliced the remainder into 3 pieces for her 3 children, ken, ron and davi

Arturiano [62]

The fraction of the cake that was ron's pieces is 1/5.

<h3>What is the fraction of the cake was ron's pieces?</h3>

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:

= 1 - 1/5

= 4/5

The fraction of the cake that was ron's pieces will be:

= 2/(1+3+4) × 4/5

= 2/8 × 4/5

= 8/40

= 1/5

Simplify 7x²-x²<br> how to simplify this maths question

kondaur [170]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to simplify the expression $\large\pmb{7x^2-x^2}$ .

$\triangle~\fbox{\bf{KEY:}}$

Combine like terms! :)

That's exactly what we need to do - combine like terms.

So, we subtract:

$\star~\large\pmb{7x^2-x^2}$

Which gives us:

$\star~\large\pmb{6x^2}$

Hope it helps you out! :D

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>
