<span>4x + 8y =40
</span><span>4x + 8* 0.8 =40
</span><span>4x + 6.4 =40
</span>4x = 40 - 6.4
4x = 33.6
x = 33.6/4
x = 8.4
The tangent trigonometric function is equal to the quotient of sine and cosine through the trigonometric identity. In this case, we are given with x = 9 tan (theta). Hence the answer to this problem is the expounded algebraic expression x = 9 sin (theta) / cos (theta).
Answer:
61 / 90, 62 /90, 63 /90, 64/90, 65/90
Explanation:
2/3 = 2 x 5 / 3 x 5
= 10 / 15
4/5 = 4 x 3 / 5 x 3
12 / 15
we can find 5 rational numbers betwen 2/3 and 4/5 by multiplying them with 5 + 1 = 6
10 / 15 X 6 /6
= 60 / 90
12/ 15 X 6 /6
= 72 / 90
the rational numbers = 61 / 90 62 /90 63 /90 64/90 65/90
Idk if you have any choices or not but it should look like 8 + 2x
How to get the answer: sum means addition, and twice a number is 2 times it. We don't know the number so we'll use x. Two times a number is 2x
And since we are adding we will put an addition sign
8 + 2x
