Blankets:$32
Towels:$16

You set it up as a system of equations.
I made the blankets x and the towels y.
You get 2 equations:
21x+21y=1008

21x+ 23y= 1040

I solved the system by solving the second equation for 21 x
21x= 1040-23y
And plugged it into the first equation
1040-23y+21y=1008
Y= 16

Then I plugged 16 in for y:
21x+23(16)=1040
X=32

Answer:

y = 2x + 2

Step-by-step explanation:

<h3>Reading the graph!</h3>

The line shown in the figure cuts the y-axis 2 units above the origin, I.e.,

the point (0, 2)

The line also meets the x-axis two units before the origin, I.e.,

the point (-1, 0)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Intercepts:</h3>

When a line meets both the axes (x-axis and y-axis), it forms intercepts.

There are two types of intercepts:

x-intercept (when the line meets the x-axis)
y-intercept (when the line meets the y-axis)

Each of their length is equal to their distance from the Origin(0, 0)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Equation of a line (intercept form):</h3>

If the x-intercept is denoted by "a" and y-intercept by "b", the equation if such a line is given by:

$\boxed{ \mathsf{ \frac{x}{a} + \frac{y}{b} = 1 }}$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Equation of the line in question:</h3>

x-intercept (a) = -1
y-intercept (b) = 2

$\implies \mathsf{ \frac{x}{( - 1)} + \frac{y}{2} = 1 }$

The sign of the denominator is taken by the numerator:

$\implies \mathsf{ - \frac{x}{1} + \frac{y}{2} = 1 }$

Taking LCM:

$\implies \mathsf{ \frac{ - 2x + y}{ 2} = 1 }$

Cross multiplying:

$\implies \mathsf{ - 2x + y = 2 }$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Isolating y:

$\implies \mathsf{ \underline{ y = 2 + 2x }}$

That's the equation of the given line!

It costs $0.60 per ft² to cover a right triangular field with sod. The side lengths of the field are 300 ft, 400 ft, and 500 ft.

algol [13]

In this triangle, we know base & perpendicular are 300 & 400 'cause 500 is the longest side which is hypotenuse

Now, Area of a triangle = ab/2 = (300)(400)/2 = 120000/2 = 60000

As cost for 1 ft² = $0.60
cost for 60000 ft² = 60000 * 0.60 = $36000

In short, Your Answer would be Option A

Hope this helps!

The total number of calories for 18 cups of milk is 1620 calories.
If two cups of milk is 180 calories then divide 180/2 to find the unit rate.
Then multiply 90 by the number of cups (18) and then you get the total number of calories for that many drinks.
