Answer:

110 words in 5 min, 220 words in 10 min

Step-by-step explanation:

y = mx (there is no intercept because you can't type anything in 0 minutes)

66 = 3m

m = 22

y = 22x

5 minutes:

y = 22(5) = 110 words

10 minutes:

y = 22(10) = 220 words

Suppose that Y varies directly with X andY equals 12 when X equals -2 what is X when Y equals -6

VLD [36.1K]

Answer:

$x=1$

Step-by-step explanation:

A direct variation equation has the following format:

$y=kx$

Where k is a constant.

We know that y is 12 when x is -2. Thus, substitute:

$12=-2k$

Divide both sides by -2:

$k=-6$

So, our direct variation equations is:

$y=-6x$

To find what x is when y equals -6, substitute in -6 for y:

$-6=-6x$

Divide both sides by -6:

$x=1$

So, our answer is 1 :)

You are creating a model of a bookcase for a dollhouse.

Goshia [24]

Answer:

If the model is 3 inches tall, the model bookcase should be <em>2 inches</em> wide.

Step-by-step explanation:

When using similar figures, set up a proportion of the model measurements to the actual measurements:

$\frac{3}{48}=\frac{x}{32}$

Then cross multiply and solve for x:

$48x=96\\x=\frac{96}{48}\\x=2$

If this helped, a brainliest would be greatly appreciated!

a family biys airline tickets online. each ticket costs $167. the family buys travel insurance with each ticket that costs $19 p

My name is Ann [436]

167 + 19 = 186x

186x + 16 = 1132

subtract 16 from both sides

186x = 1116

divide by 186 on both sides

x = 6

they bought 6 tickets total

Please help ASAP I’m confused<br><br> I WILL GIVE BRAINLIEST

neonofarm [45]

Answer: $x=4.7434$

Step-by-step explanation:

Use the pythagorean theorem $a^{2} +b^{2} =c^{2}$

plug in and solve

$x^{2} +3x^{2} =(3\sqrt{10}) ^{2}$

$4x^{2} =90$

$x^{2} =22.5$

$x=4.7424$

if you need to solve for the sides

3x = 3(4.7434) = 14.2302
