Ben bought 8 fairy sodas and 5 fairy hotdogs and spent $30.75 fairy dollars. Holly bought 7 fairy sodas and 6 fairy hotdogs and

wlad13 [49]

Set up the system of equations:

$8x + 5y = 30.75$
$7x + 6y = 33$

We'll use elimination to solve this system of equations.

Take the coefficients for y in both problems. Multiply one of them by -1:

$5 \times -1 = -5$

Since this coefficient is taken from the first problem, we'll multiply the entire second problem by this negative coefficient:

$(7x + 6y = 33) \times -5 = -35x - 30y = -165$

Take the coefficient for y in the second problem and multiply the entire first problem by that coefficient:

$(8x + 5y = 30.75) \times 6 = 48x + 30y = 184.50$

Your system should now look like this:

$48x + 30y = 184.50$
$-35x - 30y = -165$

Combine these two equations to cancel out y:

$13x = 19.50$

Divide both sides by 5 to get x by itself:

$x = 1.5$

A fairy soda costs $1.50.

Because we know the value of one of the variables, we can plug it into one of the equations:

$8(1.5) + 5y = 30.75$
$12 + 5y = 30.75$

Subtract 12 from both sides:

$5y = 18.75$

Divide both sides by 5 to get y by itself:

$y = 3.75$

A fairy hotdog costs $3.75.

Simplify this 13.) 13y² + 9y + 4y² - 31y

erastova [34]

Answer: $17y^2-22y$

Step-by-step explanation:

$13y^2+9y+4y^2-31y$

$\mathrm{Group\:like\:terms}$

$=13y^2+4y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:13y^2+4y^2=17y^2$

$=17y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:9y-31y=-22y$

$=17y^2-22y$

(6x-5y+4)dy+(y-2x-1)dx=0

Len [333]

(6x - 5y + 4) dy + (y - 2x - 1) dx = 0

(6x - 5y + 4) dy = (2x - y + 1) dx

dy/dx = (2x - y + 1) / (6x - 5y + 4)

Let X = x - a and Y = y - b. We want to find constants a and b such that

dY/dX = (a rational function)

where the numerator and denominator on the right side are free of constant terms. Substituting x and y in the equation, we have

dY/dX = (2 (X + a) - (Y + b) + 1) / (6 (X + a) - 5 (Y + b) + 4)

dY/dX = (2X - Y + 2a - b + 1) / (6X - 5Y + 6a - 5b + 4)

Then we solve for a and b in the system,

2a - b + 1 = 0

6a - 5b + 4 = 0

==> a = -1/4 and b = 1/2

With these constants, the equation reduces to

dY/dX = (2X - Y) / (6X - 5Y)

Now substitute Y = VX and dY/dX = X dV/dX + V :

X dV/dX + V = (2X - VX) / (6X - 5VX)

The equation becomes separable after some simplification:

X dV/dX + V = (2 - V) / (6 - 5V)

X dV/dX = (2 - V) / (6 - 5V) - V

X dV/dX = (2 - V - (6 - 5V)) / (6 - 5V)

X dV/dX = (4V - 4) / (6 - 5V)

- (5V - 6) / (4V - 4) dV = 1/X dX

Integrate both sides:

-5/4 V + 1/4 ln|4V - 4| = ln|X| + C

Extract a constant from the logarithm on the left:

-5/4 V + 1/4 (ln(4) + ln|V - 1|) = ln|X| + C

-5/4 V + 1/4 ln|V - 1| = ln|X| + C

-5V + ln|V - 1| = 4 ln|X| + C

Get this back in terms of Y :

-5Y/X + ln|Y/X - 1| = 4 ln|X| + C

Now get the solution in terms of y and x :

-5 (y - 1/2)/(x + 1/4) + ln|(y - 1/2)/(x + 1/4) - 1| = 4 ln|x + 1/4| + C

With some manipulation of constants and logarithms, and a bit of algebra, we can rewrite this solution as

-5 (4y - 2)/(4x + 1) + ln|(4y - 4x - 3)/(4x + 1)| = 4 ln|x + 1/4| + 4 ln(4) + C

-5 (4y - 2)/(4x + 1) + ln|(4y - 4x - 3)/(4x + 1)| = 4 ln|4x + 1| + C

-5 (4y - 2)/(4x + 1) + ln|4y - 4x - 3| - ln|4x + 1| = 4 ln|4x + 1| + C

-5 (4y - 2)/(4x + 1) + ln|4y - 4x - 3| = 5 ln|4x + 1| + C

Given that the measure of ∠x is 60°, and the measure of ∠y is 110°, find the measure of ∠z.

Nitella [24]

Answer:

Step-by-step explanation:

A triangle is always 180 degrees.

If ∠x is 60°

and ∠y is 110°,

110 + 60 = 170

∠z = 10 degrees
