Answer:
r=32/7
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
1/2r+(2)(3/4r)+(2)(-1)=1/4r+6(Distribute)
1/2r+3/2r+-2=1/4r+6
(1/2r+3/2r)+(-2)=1/4r+6(Combine Like Terms)
2r+-2=1/4r+6
2r-2=1/4r+6
Step 2: Subtract 1/4r from both sides.
2r-2-1/4r=14r+6-14r
7/4r-2=6
Step 3: Add 2 to both sides.
7/4r-2+2=6+2
7/4r=8
Step 4: Multiply both sides by 4/7.
(4/7)*(7/4r)=(4/7)*(8)
r=32/7
Answer: r=32/7

what is the equation in slope intercept form 6x-4y=12 ?
Answer:
y=6/4x-3
Step-by-step explanation:
First, you isolate the y, by subtracting 6x from each side. Then, you divide by -4 on both sides to isolate it to an individual y.
Answer:
Slope = 6/4 or 1 1/2
Step-by-step explanation:
Step 1:
6x - 4y = 12 Equation
Step 2:
y = mx + b Slope Intercept Form
Step 3:
- 4y = - 6x + 12 Subtract 6x on both sides
Step 4:
y = 6/4x + 12 Divide 4 on both sides
Answer:
Slope = 6/4 or 1 1/2

2. Select the situation below that result in zero. * 0 points A. A diver is at sea level, reaches a depth of 6 ½ feet and descends 6 ½ feet. B. The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and then rises 4 degrees.B. The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and then rises 4 degrees. C. A carbon atom has 6 negatively charged electrons and 6 positively charged protons. D. A person has a bank balance of negative $325.50 and makes a withdrawal of $325.50. E. B and C only
Answer: B and C only
Step-by-step explanation:
The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and rises 4 degrees
Initial temperature = 0
Temperature rise = 4
Fall in temperature = - 4
(Initial temperature + rise in temperature + fall in temperature)
Summing all : (0 + 4 - 4) = 0
carbon atom has 6 negatively charged electrons and 6 positively charged protons.
Net charge of atom :
(number of proton + number of electrons)
( 6 + (-6)) = 0
Write the inverse function for the function, ƒ(x) =x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.
ƒ -1(x) =
ƒ -1(4) =
Answer:
f-1(x)=x-4
f-1(4)=0
Step-by-step explanation:
to get an inverse function, replace x with y, and y with x.
y=x+4 ---> x=y+4
solve for y: x=y+4 --> y=x-4 --> f-1(x)=x-4
f-1(4)=(4)-4=0
If f(x) = 2x2 + 5x - 8 and f(x) = -10,
which of the following could be a
value for x?
-2
Answer:
x = -2 or x = -1/2
Step-by-step explanation:
We can just set up an equation where the quadratic is equal to -10, and then solve the equation:
[tex]2x^2+5x-8=-10\\2x^2+5x+2=0\\\\[/tex]
Now, factor:
[tex](2x+1)(x+2) = 0\\x=-2 \text{ or } x=-1/2[/tex]
x 2 +2x−8=
The answer is (x-2) (x+4)

11.You are filling picnic baskets. You have 18 sandwiches, 24 granola bars, and
42 apples. You want identical groups of items in each basket with no items left
over. What is the greatest number of picnic baskets you can fill?
Answer:
6
Step-by-step explanation:
divisible by 6, so 3, 4 and 7
The greatest number of baskets will be 6.
What is the greatest common factor?The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainders is called their GCF.
The greatest common factor is the largest positive number which can be divided into given numbers evenly.
Given that you are filling picnic baskets. You have 18 sandwiches, 24 granola bars, and 42 apples.
The greatest common factor between the numbers 42, 18, and 24 will be 6.
42 / 6 = 7
18 / 6 = 3
24 / 6 = 4
Therefore, the greatest number of baskets will be 6.

The measure of the sides of a
triangle are in the extended
ratio of 3:5:7. The perimeter
of the triangle is 45 in. What
are the measures of the three
sides?
a) 6, 16, 23
b) 8, 15, 22
c) 6,9,15
d) 3, 5, 7
e) 9, 15, 21
Answer:
e) 9, 15, 21
Step-by-step explanation:
First you multiply each number in the ratio by x and set it equal to the perimeter or 45 in this case.
3x + 5x + 7x = 45
Then you add the like terms and get
15x = 45
Solve for x
x = 3
Now multiply 3 by each number
3•3= 9
3•5= 15
3•7= 21
Answer: 9, 15, 21

An electrician charges an hourly rate of $50, but also charges a fixed fee for making house calls regardless of time spend on the job. One day, the electrician earned a total of $250 for a 2 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.
What four consecutive integers have a sum of 90?
Answer:
x, x+1, x+2, x+3.
Step-by-step explanation:
I took the test
Answer:
21 + 22 + 23 +24 = 90
Step-by-step explanation:
Let's represent this with x:
x+x1+x+2+x+3 = 90
Group the x's together
4x+6 = 90
subtract 6 on both sides
4x=84
x=84/4
