Solve for m:
8(m + 2) = 3(12 - 4m)
Answer:
m=1
Step-by-step explanation:
step 1: 8(m + 2) = 3(12 - 4m) remove the parentheses
step 2: 8 m + 2 = 3 12 - 4m move the terms
step 3: 8m+ 12m= 36 - 16 collect like terms and calulate
step 4: 20m=20 divide both sides
solution: m=1
Answer:
m = 1
Step-by-step explanation:
To solve for m, we will have to get m by itself on one side, with some value on the other side.
8(m + 2) = 3(12 - 4m)
Distribute the 8 on the left side and the 3 on the right side.
8m + 16 = 36 - 12m
Add 12m to both sides.
20m + 16 = 36
Subtract 16 from both sides.
20m = 20
Divide both sides by 20.
m = 1
So now we have the answer m = 1.

Six times a number is equal to 16 more than 4 times the number. Find the number.
Answer:
8
Step-by-step explanation:
Let the number be n
6*n = 16 + 4*n
6n = 16 + 4n
6n - 4n = 16
2n = 16
2n/2 = 16/2
n = 8
The product of a number z and 12 is 60
"Product" means multiply.
The product of a number z and 12: z * 12 or 12z
Put everything we know together.

HELP MEE!!!|||||||||Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to
the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank) (4 points)
Answer: There are several information's of immense importance already given in the question. Let us write them down first.
Diameter of the cylinder = 6 inches
Then
Radius of the cylinder = 3 inches.
Height of the cylinder = 3 * radius
= 3 * 3
= 9 inches
Volume of the cylinder = (pi) * (Radius)^2 * Height
= 3.14 * (3)^2 * 9
= 3.14 * 9 * 9
= 254.34 cubic inches
Jacob attempted the third problem above but when checking his work he realized he made a mistake. Identify what Jacob’s mistake was in your own words, and explain what Jacob would need to do differently to avoid making that mistake in the future:
5(x+2)-7=3x+5
5x+2-7=3x+5
5x-5=3x+5
5x-5+5=3x+5+5
5x=3x+10
5x-3x=3x-3x+10
2x=10
x=5 5[(5)+2]-7=3(5)+5
5(7)-7=3(5)+5
35-7=15+5
28=20
What happened?
Answer:
Jacob forgot to use the distributive property in the 1st step
Step-by-step explanation:
Jacob should've got 5x+10-7=3x+5 for the 2nd row.
Jacob should be more careful when distributing the numbers, and make sure to distribute into every term inside the parentheses.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given solution is
5(x+2)-7=3x+5
5x+2-7=3x+5
5x-5=3x+5
5x-5+5=3x+5+5
5x=3x+10
5x-3x=3x-3x+10
2x=10
x=5 5[(5)+2]-7=3(5)+5
5(7)-7=3(5)+5
35-7=15+5
28=20
Here we can see that the correct distribution of 5(x+2) would be 5x + 10.
Because Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10.
Jacob should be more careful when distributing the numbers, and make sure to distribute into every term inside the parentheses.

Sean buys a packet of perfumed candles that contains 12 lavender, 8 vanilla, and 20 rose-perfumed candles. He randomly takes
out a candle from the packet, replaces it, and then randomly takes out another
What is the probability that he takes out a lavender
and a rose-perfumed candle
.05
.24
.3
.15
Answer:
05.
Step-by-step explanation:
trust me dude i just took this question :D
The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15 so option (D) will be correct.
What is probability?Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Do not take underestimate probability it has several uses in daily life whether forecasts or like that.
Total number of candles = 12 + 8 + 20 = 40
Probability = desire/total
So,
Probability of taking lavender first = number of lavender/total
⇒ 12/40 = 0.3
Now since we again put the lavender into the lot it means all things remain the same.
Probability of rose-perfumed second = number of rose-perfumed /total
⇒ 20/40 = 0.5
Now the probability of A and B is the multiplication of the probability of A and B individually.
So,
The probability of taking out lavender and a rose-perfumed candle
⇒ 03 × 0.5 = 0.15
Hence "The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15".

Find the distance between the points (4,3) and ( 0,6)
Answer:
5
Step-by-step explanation:
The distance between the points (4,3) and ( 0,6) is; d = 5
The formula for distance between two coordinates is given as;
d = √((y2 - y1)² + (x2 - x1)²)
We are given the coordinates;
(4,3) and (0,6)
Thus;
x1 = 4
x2 = 0
y1 = 3
y2 = 6
Thus;
d = √((6 - 3)² + (0 - 4)²)
d = √(3² + 4²)
d = √25
d = 5

WORTH 25 POINTS!!! EASY POINTS! Plot C(-4, -5) ,D(-4,3) ,E( -3,2), and F(-8,2) in a coordinate plane. Are CD and EF congruent?
Answer: not congruent
Step-by-step explanation:
To know if CD and EF are congruent, you need to use the distance formula to find CD and EF. If the distance is the same, then they are congruent.
Distance formula: [tex]d=\sqrt{(x_{2}-x_1)^2+(y_2-y_1)^2}[/tex]
CD
[tex]d=\sqrt{(-4-(-4))^2+(3-(-5))^2}[/tex] [parenthesis]
[tex]d=\sqrt{(0)^2+(8)^2}[/tex] [exponent]
[tex]d=\sqrt{0+64}[/tex] [add]
[tex]d=\sqrt{64}[/tex] [square root]
[tex]d=8[/tex]
------------------------------------------------------------------------------------------------------------
EF
[tex]d=\sqrt{(-8-(-3))^2+(2-2)^2}[/tex] [parenthesis]
[tex]d=\sqrt{(-5)^2+(0)^2}[/tex] [exponent]
[tex]d=\sqrt{25+0}[/tex] [add]
[tex]d=\sqrt{25}[/tex] [square root]
[tex]d=5[/tex]

After finding the distance of CD and EF, we can say that they are not congruent. The line CD is 8 units long and line EF is 5 units long. Therefore, they are not congruent.
