Answer:

Step-by-step explanation:

(2x+3y)÷4-2=(2(2)+3(4)÷4-2

2*2=4+12/4-2

3*4=12

Answer:

Step-by-step explanation:

Remember to follow PEMDAS, the order of operation.

PEMDAS =

Parenthesis

Exponents (& roots)

Multiplications

Division

Addition

Subtraction

First, plug in 2 for x, and 4 for y

(2(2) + 3(4))/4 - 2

Simplify:

2 * 2 = 4

3 * 4 = 12

4 + 12 = 16

16/4 = 4

4 - 2 = 2

2 is your answer.

Here is your answer

$\bold{x=12}$

REASON:

$Concept used$ : The opposite sides of a parallelogram are equal.

So, in above given figure

$3x+7=5x-17$ (measures of opposite sides)

$5x-3x= 17+7$

$2x= 24$

$x= 24/2$

$x= 12$

Find the function value. tan495°

inysia [295]

Answer: -1

Step-by-step explanation:

You want to find an angle that is coterminal to 495. So, subtract 360 degrees until youre in the range of 0-360. I got 495 - 360 = 135°

Tangent is equal to $\frac{sin(theta)}{cos(theta)}$ , we already solved theta which was 135°

This next part is hard to explain to someone who doesnt know their trig circle, idk if you do. The angle 135 is apart of the pi/4 gang. So we know this is going to be some variant of √2/2. Sine of quadrant 1 and 2 is gonna be positive:

$sin135=\frac{\sqrt{2} }{2}$
