Answer:

−

3 x = 15 Divide each term in − 3 x = 15 by - 3 . − 3 x − 3 +15 =− 3 Cancel the common factor of − 3 . Cancel the common factor. − 3 x − 3 = 15 − 3 Divide x by 1 . x = 15 − 3 by − 3 . x = − 5

Answer:

X < 3

Step-by-step explanation:

To solve the equation 3x < -2x+15

the steps are as follow:

+ 2x to both sides

Result: 5x < 15

Then divide by 5 to both sides to get x alone.

Final Product:

x < 3

What is the area of this shape?

Dovator [93]

Answer:

The area of this shape equals $30cm^{2}$

Step-by-step explanation:

From the diagram, we can see that this shape is a parallelogram (since opposite sides are equal to each other). The formula for the area of the parallerlogram is as follows:

$Area = bh$ (where "b" is the base, and "h" is the height).

And so we get...

$Area = bh = (10)(3) = 30cm^{2}$

In ΔTUV, the measure of ∠V=90°, the measure of ∠U=70°, and UV = 9.6 feet. Find the length of TU to the nearest tenth of a foot.

Nutka1998 [239]

28.1 feet

explaination

\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{9.6}{x}

cosU=

hypotenuse

adjacent

=

x

9.6

\cos 70=\frac{9.6}{x}

cos70=

x

9.6

x\cos 70=9.6

xcos70=9.6

Cross multiply.

\frac{x\cos 70}{\cos 70}=\frac{9.6}{\cos 70}

cos70

xcos70

=

cos70

9.6

Divide each side by cos 70.

x=\frac{9.6}{\cos 70}=28.0685\approx 28.1\text{ feet}

x=

cos70

9.6

=28.0685≈28.1 feet

Type into calculator and roundto the nearest tenth of a foot.
