9.1(6)+8.7(7)=_+60.9 How do I solve this?

Answer:

The answer is <u>54.6</u>.

9.1(6)+8.7(7)=<u>54.6</u>+60.9

Step-by-step explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

9.1\times 6+8.7\times 7=x+60.9

54.6+60.9=x+60.9

Now adding on L.H.S:

115.5=x+60.9

Subtracting on both sides by 60.9 we get:

54.6=x

x=54.6

Therefore, the answer is 54.6.

Which letters from the table represent like terms? A and B B and C A and D B and D.
xenn [34]

The letters can be added together if they have similar variables.

B and C are like terms. Option B shows the like terms of letters.

<h3>What is a binomial?</h3><h3></h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign is called the binomial expression.

The attachment shows the table of letters and variables.

To multiply binomials, a form of the distributive property is used.

The table has been complete with the final values of letters which are given below.

A= (-2x) \times 4x

A = -8x^2

B = 3 \times 4x

B = 12 x

C = (-2x)\times 1

C = -2x

D = 3\times 1

D = 3

From the final values of letters, B and C are the only like terms, they can be added together since they have similar variables.

Hence we can conclude that B and C are like terms. Option B shows the like terms of letters.

To know more about the binomials, follow the link given below.

BRAINLIESTTT ASAP!!! PLEASE HELP ME :)<br><br> Explain your answer please and show your steps/work.
algol [13]

Answer:

√x

Step-by-step explanation:

First, simplify -3⁄6 to -½. Next, according to the Negative Exponential Rule, move the denominator to the numerator to get x¹\²:

bⁿ = 1\b⁻ⁿ

Then, according to the Definition of Rational Exponents [part I], rewrite this as a radical, which in this case would be √x. This is when your numerator is 1:

ⁿ√aᵐ = aᵐ\ⁿ

If you are ever in need of assistance, do not hesitate to let me know by subscribing to my You-Tube channel [USERNAME: MATHEMATICS WIZARD], and as always, I am joyous to assist anyone at any time.

**I have a video that explains all six exponential rules. It is titled "Six Exponential Procedures". I encourage you to watch the video and gain alot more knowledge from it, so you can better understand the concept.

Goldilocks needs to find at least 12 lb of gold and at least 18 lb of silver to pay the monthly rent. There are two mines in whi
VikaD [51]

Answer:

cave 1 -  2g= 12 gold,  g is 6

2s  = 18 silver,  s = 9

so she would stay 9 days digging for silver and 6 for gold

cave 2-  1g = 12 gold,  g is 12

3s = 18 silver,  s = 4

she would stay 4 days looking for silver and 12 for gold

cave 1 is better because its less days since she is digging for gold and silver at same time it would only take maybe 10 days but for cave 2 its would take abt 13 days

Step-by-step explanation: idk i just put some stuff together sorrry its wrong..... but i hope it helps..
