Simplify 2x-{3x-[x-(2x-1)]}

Mathematics
1 answer:
vlada-n [284]3 years ago
3 0

Answer:

Step-by-step explanation:

Working from the inside out, we take it one bracket at a time

2x-{3x-[<u>x-(2x-1</u>)]}

let's tackle the underlined prolem first

x-(2x-1)

= x-2x+1

= -x+1..we can also write this as 1-x if need be

So we now have (2x-(<u>3x-(-x-1)))</u>

Again, we tackle the undelined problem first

3x-(-x-1)

= 3x+x+1

= 4x+1

So we now have 2x-(4x+1)

Now we can tackle this together

= 2x-4x-1

= -2x-1

2m+3+4m+5 advice and correct solution
Hunter-Best [27]
Hey there!

On this problem, we have to combine like terms. A like term in this sense doesn't have to have the same coefficient, but it has to have the same variable.

Our like terms are 2m and 4m, along with 3 and 5.

When we add 2m and 4m we get 6m, and when we add 5 and 3 we get eight.
Notice how 5 and three are like terms because they're both whole numbers and don't have any variables.

Your solution is 6m + 8.

My advice to you is pay attention to your like terms and don't mix them up. A strategy is to underline like terms in the same color.

Hope this helps!

Answer:

6\sqrt{6}

Step-by-step explanation:

Simplify using a\frac{n}{m} =\sqrt[m]{a^n} :\sqrt{6^3}

Factor and rewrite the radicand in exponential form: \sqrt{6^2 x 6}

Rewrite the expression using \sqrt[n]{ab} =\sqrt[n]{a}*\sqrt[n]{b} : \sqrt{6^2x\sqrt{6}

Simplify  the radical expression

 G is the answer because if you set x as the value of B, then x+(x+10)+(x+30)=180 so x=46.67. then you add 10 to that because the value of A is 10 more than B

Total cards in a deck=52
Face cards =12
So probability of picking a face card is 12/52=3/13
Because probability of an event =chances of favourable outcomes/total number of outcomes
