Answer:
M = 60
Step-by-step explanation:
First, use the distributive property:
12(m + 15) = 900
12 x m = 12m
12 x 15 = 180
We get the equation 12m + 180 = 900
Subtract 180 from both sides.
12m + 180 - 180 = 900 - 180
We get the equation 12m = 720
Divide by 12 on both sides.
12m/12 = 720/12
We get m = 60
I would appreciate brainliest but if not that's ok!
Answer:
60
Step-by-step explanation:
The equation is 12m +180=900 because we already did the distributive property. So now we have to minus 180 from both sides which gets us 12m=720. Now we divide both sides by 12. So 12m/12=m and 720/12=60. This leaves us with the answer, m=60.
Solve the equation 3 (p-1) = 2p – 11.
Answer:
p = - 8
Step-by-step explanation:
3 (p - 1) = 2p - 11
3p - 3 = 2p - 11
3p - 2p = -11 + 3
p = -8
Answer:
p = - 8
Step-by-step explanation:
Given
3(p - 1) = 2p - 11 ← distribute parenthesis on left side
3p - 3 = 2p - 11 ( subtract 2p from both sides )
p - 3 = - 11 ( add 3 to both sides )
p = - 8

Give value to four significant figures.
Answer:
very specific...sus...yea no one knows
Step-by-step explanation:
In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .

2. Solve x - 19 <81. Then graph the solution.
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
What is pi/4 a reference angle for
3+2x = 41
Need help
Show work
Answer:
x=16
Step-by-step explanation:
when solving for a variable, get the variables to one side of the equation and the numbers to the other side.
3+2x=41
*minus 3 from both sides of the equation to get rid of the number on the side of variables of the equation*
2x=38
to get one variable alone, divide the whole equation by 2
x=16

what is 3(x - 4)= 12x
Answer:
x = 4/5
Step-by-step explanation:
3(x-4)=12x
3x-12=12x
3x+12x-12=12x-12x
15x-12=0
15x-12+12=0+12
15x=12
15x/15=12/15
x = 4/5

Answer:
B. 2200 ft²Step-by-step explanation:
To find the area, calculate two parts and add up
The triangle section has sides:
40 ft and 50 - 30 = 20 ftThe area:
1/2*20*40 = 400 ft²The rectangle section has sides:
30 ft and 20 + 40 = 60 ftThe area:
30*60 = 1800 ft²Total area:
400 + 1800 = 2200 ft²Correct option is B

A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?
Answer:
$29.25
Step-by-step explanation:
The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.

Answer:
z = 44
Step-by-step explanation:
180 - (44+52) = 180 - 96 = 84º
180 - 84 = 96º
180 - (96 + 40) = z
180 - 136 = z
z = 44
Select the correct answer.
Simplify the expression
Answer: A
Step-by-step explanation:
Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]
