Answer:

x is 35

Step-by-step explanation:

First do 180 -40 and get 140. Then add 3x plus x to get 4x because they are the same value/ Do 140/ 4x and get 35. X equals 35.

Answer:

35, 135

Step-by-step explanation:

You first add the like terms. 3x + x = 4x. Next you form an inequality.

40 - 4x = 180.

x = 35

Since x equals 35 you do 3 * 35. 3(35), which is 105.

35 + 40 + 105 = 180!

Solve the equation. Round to the nearest hundredth. Show work.

Elis [28]

Answer:

The value of x = 0.41

Step-by-step explanation:

∵ $6e^{2x}-5e^{x}=6$

Let $e^{x}=y$

∴ $e^{2x}=y^{2}$

∴ 6y² - 5y = 6

∴ 6y² - 5y - 6 = 0 ⇒ factorize

∴ (3y + 2)(2y - 3) = 0

∴ 3y + 2 = 0 ⇒ 3y = -2 ⇒ y = -2/3

∴ 2y - 3 = 0 ⇒ 2y = 3 ⇒ y = 3/2

∵ $y=e^{x}$

∴ $e^{x}=\frac{-2}{3}$ ⇒ refused

( $e^{ax}$ never gives -ve values)

∵ $e^{x}=3/2$ ⇒ insert <em>ln</em> in both sides

∵ $lne^{ax}=axlne=ax$ ⇒ <em>ln</em>(e) <em>= 1</em>

∴ $xlne=ln(3/2)$

∴ x = ln(3/2) = 0.41

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

If ab = 10 and a2 + b2 = 30, what is the value of<br> (a + b)^2?

Bogdan [553]

Ab=10
a^2+b^2=30
((a+b)^2=a^2+2ab+b^2=a^2+b^2+2*10=30+20=50
