Solve the equation. Show the process, not just an answer. 6.EE.7
Natalka [10]

Isolate the variable, note the equal sign, what you do to one side, you do to the other.

1) 4k = 24

Isolate the variable, k. Divide 4 from both sides of the equation:

(4k)/4 = (24)/4

k = 24/4

k = 6

2) 34 + h = 60

Isolate the variable, h. Subtract 34 from both sides of the equation:

34 (-34) + h = 60 (-34)

h = 60 - 34

h = 26

3) 1/5x = 30

Isolate the variable, x. Multiply 5 to both sides of the equation:

(5) * (1/5)x = (30) * (5)

x = 30 * 5

x = 150

4) m - 42 = 85

Isolate the variable, m. Add 42 to both sides of the equation:

m- 42 (+42) = 85 (+42)

m = 85 + 42

m = 127

Graph y=x^2+1 is it a function
frez [133]
Hello,

The graph of y = x² + 1 most certainly is a function. 
It is a function because for every value of x, there is only one value of y. 

The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.

Rammy has $9.60 to spend on some peaches and a gallon of milk. Peaches cost $1.20 per pound, and a gallon of milk cost $3.60.
lesya692 [45]

Answer:

Rammy can buy 5 pounds of peaches

Step-by-step explanation:

1.20(5) + 3.60 = 9.60

subtract the cost of the gallon from the total amount and then divide the leftover cost $6 by $1.20 and you'll get 5.

Video games sold: x Revenue function: R(x) = 60x Cost function: C(x) = 12 + 7x Profit function: P(x) = What is the profit earned
nataly862011 [7]

Answer:

Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.

Step-by-step explanation:

In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x  for the sale of x video games

As we know profit = sale price - cost price

Therefore P(x) = R(x) - C(x)

Or P(x) = (R-C)x = 60x - (12+7x)

P(x) = 60x -12 - 7x

P(x) = 53x -12

Now the profit on selling 20 video games will be

P(20) = 53×20 -12 = 1060 -12 = 1048.

If it takes 3,127 feet of computer cable to wire an office building, how much cable will be left if the wire is taken from a 5,0
anyanavicka [17]
This is one of the most complex problems I've seen on Brainly. If you don't understand after reading my lengthy explanation, just tell me.

You have 5000 feet of reel. The office building uses 3127 feet of cable.
So you do 5000-3127 to find the remaining amount of reel.

5000 - 3127 = 1873

Whew! That was quite difficult, wasn't it?
