Answer:

Step-by-step explanation:

So first do 104+76+104=284

Now form the equation 10x-4+284=360

It is 360 because this is a quadrilateral.

Now combine like terms.

10x+280=360

10x=80

x=8

Check 80-4=76

The other angle is 76 so you know your answer is correct

Two classmates, Annie and Whitney, plan to meet in the computer lab to type up their research papers. Annie can type at a speed

madam [21]

The page count will be 10 when the two students will reach the same count.

Step-by-step explanation:

Given,

Typing speed of Annie = 3 pages per hour

Pages already typed by Annie = 4

Let,

x be the number of hours.

y be the total pages typed.

y = 3x+4 Eqn 1

Typing speed of Whitney = 1 page per hour

Pages already types by Whitney = 8

y = 1x+8 Eqn 2

For same number of pages;

Eqn 1 = Eqn 2

$3x+4=1x+8\\3x-1x=8-4\\2x=4$

Dividing both sides by 2

$\frac{2x}{2}=\frac{4}{2}\\x=2$

Putting x=2 in Eqn 1

$y=3(2)+4\\y=6+4\\y=10$

Putting x=2 in Eqn 2

$y=2+8\\y=10$

The page count will be 10 when the two students will reach the same count.

7m + 3mn when m = 8 and n = 14

zysi [14]

Answer:

392

Step-by-step explanation:

If we have the expression $7m+3mn$ and we know the values of m and n, we can just substitute inside the expression and solve.

$7\cdot8 + 3\cdot8\cdot14\\\\56+336\\\\392$

Hope this helped!

what is the equation in slope intercept form of the line that passes through the point (-4,47) and (2,-16)

Vilka [71]

The slope-intercept form:

$y=mx+b$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-4, 47) and (2, -16). Substitute:

$m=\dfrac{-16-47}{2-(-4)}=\dfrac{-63}{6}=-\dfrac{63:3}{6:3}=-\dfrac{21}{2}$

Therefore we have:

$y=-\dfrac{21}{2}x+b$

Put the coordinates of the point (2, -16) to the equation:

$-16=-\dfrac{21}{2}(2)+b\\\\-16=-21+b\qquad\text{add 21 from both sides}\\\\5=b\to b=5$

Answer: $\boxed{y=-\dfrac{21}{2}x+5}$
