how do you solve 8 = 3r - 1
add 1 to both sides then divide by 3. the answer should be r=3
Answer:
r=3
Step-by-step explanation:
First, you would add 1 to both sides so:8+1=3r-1+1 so that gives you 9=3r.
Then, you divide 3 from both sides. 9/3=3r/3 so that gives you r=3
Which steps can be used in order to determine the solution to Negative 1.3 + 4.6 x = 0.3 + 4 x? Subtract 1.3 from both sides of the equation, add 4x to both sides of the equation, then divide by the coefficient of x. Subtract 1.3 from both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4x from both sides of the equation, then divide both sides by the coefficient of x.
Answer:
its D
Step-by-step explanation:
got it correct on a test :)
The correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.
What is the linear equation?The linear equation is an equation where the highest degree of the variables used in the equation is 1.
For example 9x+5=23
Given the equation is -1.3 +4.6x= 0.3+ 4x
In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.
Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.
Here the given equation is -1.3 +4.6x= 0.3+ 4x
Step-1: Adding 1.3 to both sides of the equation
⇒-1.3 +4.6x +1.3 = 0.3+ 4x +1.3
⇒4.6x = 4x+1.6
Step-2: subtracting 4x from both sides of the equation
⇒4.6x -4x = 4x+1.6-4x
⇒ 0.6x=1.6
Step-3: dividing both sides by the coefficient of x i.e. 0.6.
⇒0.6x/0.6 = 1.6/0.6
⇒x= 2.67
Therefore the correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

Lindsey Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 867 points. The number of two-point field goals that Lindsey made was 66 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 36 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season. How many free throws, 3 pointers, and 2 pointers did she make?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total point = 867
Let :
number of 3 point goals = p
Number of 2 point goals = 2p - 66
Number of 1 point goals = (2p - 66) - 36 = 2p - 102
Hence,
3p + 2(2p - 66) + 2p - 102 = 867
3p + 4p - 132 + 2p - 102 = 867
3p + 4p + 2p - 234 = 867
9p - 234 = 867
9p = 867 + 234
9p = 1101
p = 122.33
2 pointer = 2p - 66
2(122.33) - 66 = 178.67
1 point = 2p - 102
2(122.33) - 102
= 142.67

Step-by-step explanation:
(5x+12) (3x+16) multiply each term in the first parentheses by each term in the second parentheses
15Xx 3x+5Xx16+12x3x+12x16
15x^2+166X+192
ANSWER 15x^2+116+192
Answer:
The chosen topic is not meant for use with this type of problem.
Step-by-step explanation:
The best way to try and solve is using the quadratic formula. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
( 5x + 12 ) x ( 3x + 16 )
Step one : use the distributive factor. To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
5x x 3x
5x x 16
12 x 3x
12 x 16
15x^2 + 80x + 36x + 192
Step two: Combine like terms
15x^2 + 116x + 192
Step three: Solve the equation for x by finding a
, b, and c of the quadratic then applying the quadratic formula.
x = - 12/5 , -16/3

Koto’s average velocity along her route was 4.5 m/s. She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west. What was the time of her trip? (There are 60 seconds in 1 minute.) 18.5 minutes 20.4 minutes 2 hours 3 hours
Answer:
18.5 minutes
Step-by-step explanation:
Koto’s average velocity along her route was 4.5 m/s.
She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.
5000 meters west - 5000 meters east = 0
20,000 south - 15000 north = 5000 meters
4.5 meters = 1 second
5000 meters = x seconds
Cross Multiply
4.5 × x = 5000 × 1
x = 5000/4.5
x = 1111.11111111 seconds
There are 60 seconds in 1 minute.
60 seconds = 1 minute
1111.11111111 = y minutes
60 × y = 1111.11111111 × 1
y = 1111.11111111/60
y = 18.5185185185 minutes

You purchase disposable plates, cups, and forks for a cookout. Plates are sold in packages of 24, cups in packages of 32, and forks in packages of 48. What are the least numbers of packages you should buy in order to have the same number of plates, cups, and forks?
Answer:
96 packages
Step-by-step explanation:
We solve for this question using Lowest Common Multiple (LCM) method
Step 1
We list multiples of each number until the first common multiple is found. This is referred to as the lowest common multiple.
From the question , we are told:
Plates are sold in packages of 24
Cups in packages of 32
Forks in packages of 48
Multiples of 24:
24, 48, 72, 96, 120, 144
Multiples of 32:
32, 64, 96, 128, 160
Multiples of 48:
48, 96, 144, 192
Therefore,
LCM(24, 32, 48) = 96
Hence, the least numbers of packages you should buy in order to have the same number of plates, cups, and forks is 96 packages

x=7.5
Total area = 27+15 = 42
Step-by-step explanation:
For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.
Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:
9+3+3+3.5+3.5+x+x+2=39
24+2x=39
2x=15
x=7.5
For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.
Rectangle A = 9*3=27
Rectangle B = 7.5*2=15
Total area = 27+15 = 42

Step 1: Simplify both sides of the equation.
3x+5−(5x+8)=−4x−7
3x+5+−1(5x+8)=−4x−7(Distribute the Negative Sign)
3x+5+−1(5x)+(−1)(8)=−4x−7
3x+5+−5x+−8=−4x−7
3x+5+−5x+−8=−4x+−7
(3x+−5x)+(5+−8)=−4x−7(Combine Like Terms)
−2x+−3=−4x−7
−2x−3=−4x−7
Step 2: Add 4x to both sides.
−2x−3+4x=−4x−7+4x
2x−3=−7
Step 3: Add 3 to both sides.
2x−3+3=−7+3
2x=−4
Step 4: Divide both sides by 2.
