Answer: x=2

3x−9x+7−3=−8

Step 1: Simplify both sides of the equation.

3x−9x+7−3=−8

3x+−9x+7+−3=−8

(3x+−9x)+(7+−3)=−8

−6x+4=−8

−6x+4−4=−8−4

−6x=−12

−6x

−6

−12

Find the measure of the angle x to the nearest tenth. Question 7 options: 33. 5Â° 56. 5Â° 28. 9Â° 44. 3Â°.

Nina [5.8K]

The question is an illustration of right-angled triangles

The approximated value of x is 33.5 degrees

The given parameters are:

$\theta = x$

$Hypotenuse = 58$

$Opposite = 32$

To determine the measure of angle x, we simply make use of the following sine ratio.

$\sin(\theta) = \frac{Opposite}{Hypotenuse}$

So, we have:

$\sin(x) = \frac{32}{58}$

$\sin(x) = 0.5517$

Take arc sine of both sides

$x = \sin^{-1}(0.5517)$

This gives

$x = 33.5$

Hence, the approximated value of x is 33.5 degrees

An internet service provider is implementing a new program based on the number of connected devices in each household. Currently

oee [108]

Cost of the current plan: $175
Number of devices: x
Cost of the new plan: $94+($4.50/device)x

Cost of the new plan is less than the current plan:
$94+($4.50/device)x<$175

Solving for x:
$94+($4.50/device)x-$94<$175-$94
($4.50/device)x<$81
(device/$4.50)($4.50/device)x<(device/$4.50)($81)
x<18 devices

Please, see the attached file.
Thanks.
