Answer:
B: Equation containing fractions
Step-by-step explanation:
A proportion equates two fractions.
A fractional equation contains the unknown in the denominator of one or more terms. (A proportion may be written as a fractional equation.)
Here, the equation has the variable in the numerator of the terms in which it appears, so the equation is not a fractional equation. It is not equating two fractions, so is not a proportion. It contains fractions, so it is an ...

_____
Multiplying the equation by 36 gives ...
3x = 204 -8x -180 +9x
2x = 24 . . . . . subtract x
x = 12 . . . . . . .divide by 2
A system of equations is a collection of two or more equations with the same variables. When solving this system, u need to find the unknown variables. One way of solving a system of equations is by substitution.
example :
2x + 2y = 6 (equation 1)
3x + y = 4 (equation 2)
we need to pick a variable and isolate it. The easiest one to pick since it is already by itself is the y in the second equation.
3x + y = 4.....subtract 3x from both sides
y = -3x + 4
now we can sub -3x + 4 in for y in the 1st equation...u have to make sure u sub it back into the 1st equation and not the same equation u used to find it.
2x + 2y = 6.....sub in -3x + 4 in for y and solve for x
2x + 2(-3x + 4) = 6...distribute thru the parenthesis
2x - 6x + 8 = 6...subtract 12 from both sides
2x - 6x = 6 - 8...simplify
-4x = -2...divide both sides by -4
x = -2/-4
x = 1/2
now that we have a numerical number for x, u can sub this back into either of ur equations to find a numerical answer for y.
y = -3x + 4...when x = 1/2
y = -3(1/2) + 4
y = -3/2 + 4
y = -3/2 + 8/2
y = 5/2
so ur solution is : (1/2,5/2) <===
and u can check ur answers by subbing them into ur equations to see if they satisfy both equations...because for it to be a solution to this system, it has to satisfy both equations and not just one of them
Answer:
2A/h = b
Step-by-step explanation:
A= (1/2)(b)(h)
Multiply each side by 2
2A = 2*1/2 *b*h
2A = bh
Divide each side by h
2A/h = bh/h
2A/h = b
Answer:
208cats
Step-by-step explanation:
⅝=tongue
³/16=straw=39cats
⅝+³/16=13/16
meaning total number of cats is 16/16
If ³/16=39cats
16/16=?
39×16/3
=208cats
The probability that an average 6-sided dice rolls on four is 1/6
