Answer:

x=66

Step-by-step explanation:

x/6 +4=15

or, x+24/6=15

or,x+24=90

or,x=90-24

Hence, x=66

Hello there! x = 66.

x/6 + 4 = 15

This means that since 15 - 4 = 11, x/6 = 11.

Given the two numbers and a variable, we can multiply:

6 x 11 = 66

66/6 = 11

Therefore, x = 66

Hope this helps!

Dash offers and unlimited talk and texting plan for $80 per month AB&C charges $0.20 per text message and $55 for 1,000 min
mr_godi [17]

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

Answer:

z = 4.5

Step-by-step explanation:

∠B = ∠B      ∠BAD = 90° - ∠B = ∠C

ΔBAD ~ ΔBCA

AB / z = BD / AB

z = AB * AB / BD = 3*3 / 2 = 4.5

(2y+1.6)/0.8=30/2.5<br> Please Help!<br> Solve for Y
galina1969 [7]

y = 4

first note that the right side simplifies to 12, equation can be written

\frac{2y+1.6}{0.8} = 12 ( multiply both sides by 0.8 )

2y + 1.6 = 9.6 ( subtract 1.6 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4
