Complete Question:
The perimeter of triangle DEF is 3x + 3y. Find the measure of the missing side. (One side is x-y, the other is x+y)
Answer:
[tex]Side\ 3 = 2x+ 3y[/tex]
Step-by-step explanation:
Given
[tex]P = 4x + 3y[/tex] --- Perimeter
[tex]Side\ 1 = x - y[/tex]
[tex]Side\ 2 = x + y[/tex]
Required
Determine Side 3
The perimeter of a triangle is calculated as:
[tex]Permeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]
[tex]4x + 3y = x - y + x + y + Side\ 3[/tex]
Collect Like Terms
[tex]4x - x - x+ 3y-y + y = Side\ 3[/tex]
[tex]2x+ 3y = Side\ 3[/tex]
[tex]Side\ 3 = 2x+ 3y[/tex]
What quantity of 61% hydrochloric acid solution must be mixed with a 21% hydrochloric acid solution to produce 277.5 mL of 53% solution?
Answer:
222 mL
Step-by-step explanation:
okay so lets multply them lets call the quantity of hydrocloric acid x
so 61x+ 21(277.5-x)= 53*277.5
61x+ 21*277.5-21x= 53*277.5
40x=(53-21)(277.5)
40x= (32)(277.5)
x= 222 mL

What is the equation for this line, in Slope Intercept Form (6,1) and (2,-1)
Answer:
y=1/2x-2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(2-6)
m=-2/-4
m=1/2
y-y1=m(x-x1)
y-1=1/2(x-6)
y=1/2x-6/2+1
y=1/2x-3+1
y=1/2x-2

3x+2=5x-(2x+1) what is x
Answer:
No solution
Step-by-step explanation:
Combine like terms on the right hand side of equation
3x + 2 = 3x -1
This cannot be true so there are no solutions.
Answer:
No soultion :)
Step-by-step explanation:
3x+2=5x-(2x+1)
3x+2=5x-2x-1
3x-3x+2=5x-2x-3x-1
all xs cancel out
2 does not equal -1
There is no solution
Someone please explain this it’s confusing me.
Answer:
x = 4 radical 3 / 3
Step-by-step explanation:
this is a 30-60-90 triangle
the side across from the angle 30 is L
the side across from the angle 60 is L√3
the side across from the angle 90 is 2L
we are given the side across from 60⁰ so we know that:
2 = L√3
we want to solve for L, so we must divide both sides by √3 (radical three)
2/√3 = L√3/√3
you would get 2/ √3 = L, because the radical three cancels out on the L side.
but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3
2 times √3 and √3 times √3
you get 2√3/√9
radical nine can simplify
2radical3/3 or 2√3/3
we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L
multiply the number infront of the radical by two and get
4√3/3
x=4 radical 3 divided by 3

Simplify the following using the Distributive Property: -2(x+10)
Answer:
[tex]\bold{-2x-20}[/tex]
Step-by-step explanation:
Hi there!
Let's clarify what the Distributive Property is.
It's a property that states
[tex]\bold{a(b+c)=ab+ac}[/tex]
So, we take a number a, multiply it by b and c, and add the products.
Now, let's use this property to simplify our expression:
[tex]\bold{-2(x+10)}[/tex]
[tex]\bold{-2x-20}[/tex]
Hope it helps! Enjoy your day!
