Answer: x=12
Step-by-step explanation: 10(x−3)=90
(10)(x)+(10)(−3)=90 (Distribute)
10x+−30=90
10x−30=90
Step 2: Add 30 to both sides.
10x−30+30=90+30
10x=120
Step 3: Divide both sides by 10.
x=12

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 .

Jenna won 77 toys playing basketball at her school's game night. Later, she gave four to each of her friends. She only has 9 remaining. How many friends does she have?
Answers
The equation can be written as:
77 - 4x = 9 where 77 is the total number of toys, 4 is how many toys she gave to each friend, x is the number of friends, and 9 is the toys remaining.
To solve for x, the number of friends:
77 -4x=9
Subtract 77 from both sides
77-77 -4x= 9-77
-4x= -68
Then divide both sides by -4 to isolate x.
-4x/-4 = 1x and -68/-4 = 17.
1x= 17, so the number of friends is 17.
My point exactly in algebra.

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]

z = 44
Step-by-step explanation:
180 - (44+52) = 180 - 96 = 84º
180 - 84 = 96º
180 - (96 + 40) = z
180 - 136 = z
z = 44

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?
Answers
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.
please do all of these :)

Solve the equation 3 (p-1) = 2p – 11.
Answers
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
