Answer:
We get that √48 = 2⋅2√3. Lastly, step three says to simplify, so we go ahead and multiply the 2⋅2 outside of the square root to get 4√3. That's it! We get that √48 = 4√3.
Step-by-step explanation:
Answer:
The correct answer is √48 = 4√3.

Solve the system of linear equations below by substitution.
y = -2x + 6
-4x - 6y = 4
Group of answer choices
(-2, 10)
(5, -4)
(3, 0)
(0, 6)
Answer:
(5, -4)
Step-by-step explanation:
Substitute y from the first equation into the second equation:
-4x - 6(-2x + 6) = 4
Simplify:
-4x + 12x - 36 = 4
8x = 40
x = 5
The only answer choice where x = 5 is (5, -4).
Answer:
[tex]\boxed {\boxed {\sf (5, -4)}}[/tex]
Step-by-step explanation:
We are given the two equations:
[tex]y= -2x+6 \\-4x-6y=4[/tex]
We are asked to solve by substitution. Since we know that y is equal to -2x+6, so we can substitute the expression in for y in the second equation.
[tex]-4x-6y=4[/tex]
[tex]-4x-6(-2x+6)=4[/tex]
Now, solve for x by isolating the variable on one side of the equation.
First, distribute the -6 into the expression. Multiply each term in the parentheses by -6.
[tex]-4x+ (-6*-2x)+(-6*6)=4[/tex]
[tex]-4x+12x+(-6*6)=4[/tex]
[tex]-4x+12x-36=4[/tex]
Combine like terms. There are 2 x terms that can be added.
[tex](-4x+12x)-36=4[/tex]
[tex]8x-36=4[/tex]
36 is being subtracted from 8x. The inverse of subtraction is addition, so add 36 to both sides of the equation.
[tex]8x-36+36=4+36[/tex]
[tex]8x=40[/tex]
x is being multiplied by 8. The inverse of multiplication is division, so divide both sides by 8.
[tex]\frac{8x}{8} =\frac{40}{8}[/tex]
[tex]x=5[/tex]
x is known, so we can find y using the first equation.
[tex]y=-2x+6[/tex]
x is equal to 5, so substitute the value in.
[tex]y=-2(5)+6[/tex]
Multiply first.
[tex]y=-10+6[/tex]
Add.
[tex]y=-4[/tex]
A solution is written as (x,y). So, the solution to this equation is (5, -4).

Step-by-step explanation:
A salesman's commission is directly proportional to his total sales. If the commission is $100 for $1000 in sales, find the commission for $1750 in sales.
The commission of the salesmen with the given ratio will be $175.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The commission is $100 for $1000 in sales.
Ratio of commission to sales = 100/1000 = 0.1
With the same ratio,
Commission/1750 = 0.1
Commission = 1750 x 0.1 = $175
Hence "The commission of the salesmen with the given ratio will be $175".

A) 18m - 45n - 90
B) 18m + 45n + 90
C) 18m + 5n + 90
D) 18m + 5n + 10
Answer:
B
Step-by-step explanation:
9 multiple 2m = 18m
9 multiple 5n = 45n
9 multiple 10= 90
Answer:
B
Step-by-step explanation:
9×2m=18m
9×5n=45n
9×10=90
so,our answer is 18m+45n+90
A scientist used 786 milliliters of a liquid for an experiment. How many liters of the liquid did the scientist use for this experiment?
Answer:
0.786 liters
Step-by-step explanation:
786/1000 = 0.786
Answer:
the answer is 0.786 liters
Step-by-step explanation:
because 1 milileter is 0.001 liter, when you multiply 786 and 0.001 you get 0.786. Your welcome (pls give brainliest)

Type your answer in the box.You may use numbers.Symbols.And /or text in your answer. Simplify the expression completely.Leave your answer in radical form. 60 ÷ 5
Answer:
60÷5 = 12
Step-by-step explanation:
Given the expression 60 ÷ 5, we ate yo simplify it in its simplest form.
Write the factors of 60 first
60 = 5 × 12
60÷5 = (5×12)÷5
60÷5 = (5×12)/5
60÷5 = 5/5 × 12
60÷5 = 1×12
60÷5 = 12
Hence the answer to the given expression is 12.

These two lines are parallel Write an equation for each line
The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.
What is the equation of a parallel line?Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.
The intercepts of the line are (0, -3.2) and (4, 0). Then the equation of the line is given as,
y + 3.2 = [(0 + 3.2) / (4 - 0)](x - 0)
y = 0.8x - 3.2
The equation of the other parallel line that passes through the origin will be given as,
y = 0.8x
The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.
