steps for 540 + 6x = 810
Answer:
x = 45
Step-by-step explanation:
[tex]540 + 6x = 810[/tex]
Step 1 : Collect like terms
[tex]6x = 810 - 540[/tex]
Step 2 : Simplify
[tex]6x = 270[/tex]
Divide both sides of the equation by 6
[tex] \frac{6x}{6} = \frac{270}{6} [/tex]
Step 4 : Simplify
[tex]x = 45[/tex]
I hope it helps :)
Answer:
Well...X=45
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0
Pull out like factors :-270 + 6x = 6 • (x - 45)
Solve : x-45 = 0::
Add 45 to both sides of the equation: x = 45

On a test, Marcus is asked to simplify . Here is his work:
√128 = √16 · √8 = 4√8
Which statement best describes Marcus' answer?
He is incorrect because 16 times 8 is not 128.
He is incorrect because he did not use the largest perfect square.
He is incorrect because the 4 and the 8 should be switched around in his answer.
He is correct.
Answer:
He did not use the largest perfect square
Step-by-step explanation:
4 [tex]\sqrt{8}[/tex] is the correct answer
What is square root ?
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16. The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.
Given,
[tex]\sqrt{128}[/tex]
we divide the number 128 by 2 four times, we get
= [tex]\sqrt{8*2*2*2*2}[/tex]
= 2*2[tex]\sqrt{8}[/tex]
=4 [tex]\sqrt{8}[/tex]
Therefore, 4 [tex]\sqrt{8}[/tex] is the correct answer

Triangle is 35 inches, what is the value of x?
Please show work if possible! Will mark brainliest!
Answer:
Perimeter = A + B + C
Perimeter = 35
A = 2x
B = x+4
C = 13

A rocket is launched from the launch pad at a speed of 700 km/hr. How far will the rocket have traveled after 1.0 hr?
Step-by-step explanation:
The answer is
Distance is 42000 kmph
The distance the rocket has traveled after 1 hour with a speed of 700km/hour is 700 km.
Given,
A rocket is launched from the launch pad at a speed of 700 km/hr.
We need to find how far will the rocket has traveled after 1.0 hr.
What is speed?Speed is the ratio of distance per time.
Speed = Distance /Time
Its unit is km/hour or m/second.
We have,
Speed = 700 km/h
Distance = D
Time = 1 hour
From the speed formula:
Speed = Distance / Time
700 = Distance / 1
700 km / hour x 1 hour = Distance
Distance = 700 km
Thus the distance the rocket traveled after 1 hour with a speed of 700km/hour is 700 km.

The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.

erics cell phone service costs $40.00 a month for unlimited calls. he also pays $0.02 for each text message he sends. what equation represents the total cost, c, in dollars, for when eric sends t text message
Answer:
40.021
Step-by-step explanation:
Unlimited calls = $40
Text message = $0.021
NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.
Total cost = Cost of unlimited calls + cost of text messages
C = $40 + $0.021
= $40.021
Therefore, the equation which represent the total cost in dollars for a month is 40.021

Lisa finds a treasure chest full of 1000 jewels: 600 emeralds, 300 sapphires, and 100 rubies. She stuffs her pockets full of jewels completely at random, but they can only hold 100 jewels. What is the probability that all 100 jewels she took were sapphires?
Given:
Total number of jewels = 1000
Emeralds = 600
Sapphires = 300
Rubies = 100 rubies
100 jewels she took randomly.
To find:
The probability that all 100 jewels she took were sapphires.
Solution:
Number of selected jewels = 100
Total number of jewels = 1000
We have to select 100 out of 1000.
So, the total number of outcomes [tex]=^{1000}C_{100}[/tex]
Number of sapphires = 300
We have to select 100 out of 300 sapphires .
So, the favorable outcomes [tex]=^{300}C_{100}[/tex]
Now,
[tex]\text{Required probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Required probability}=\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex]
Therefore, the required probability is [tex]\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex].

It costs $11.50 to rent a canoe and $5.50 to use the canoe for an hour. You have $28. Write an equation that represents the number h of hours you can rent the canoe
Answer:
(28 - 11.5) ÷ 5.5
Step-by-step explanation:
So let's examine this question.
We have already payed $11.50 the rent the canoe, so we have $16.50. Divide that by $5.50, and you get 3. So, 3 hours.
Now for the expression.
You start out with $28. You subtract $11.50 from it because it is being used to rent the canoe. You then divide your answer by $5.50 to determine how many hours you can use the canoe for.
Hmm.
(28 - 11.5) ÷ 5.5 = h
(28 - 11.5) ÷ 5.5 = 3
