Answer:
x = -5 +
Step-by-step explanation:
f(x) = x² + 10x - 1
x² + 10x = 1
x² + 10x + 25 = 1 + 25
(x + 5)² = 26
take the square root of each side to get:
x + 5 = √26
x = √26 - 5 or -5 + √26
It would be 8/1000 as a fraction
Answer:
x is 24° it is bcs triangle have at all 180°
that bigger one have 180-94-41=45° on right side
180-111-45=24° ez
The probability of winning a game of checkers against your friend is 67%.
<h3>What is the probability of winning a game of checkers against my friend?</h3>
Probability can be described as the process of determining the chances of an event happening. The chances that an event would occur has a value that lies between 0 and 1. A value of 0 is given when the event does not occur and a value of 1 if the event occurs.
The probability of winning a game of checkers = probability of winning both games / probability of winning a game of chess
20% / 30% = 67%

Answer:
Skiing costs $30 per hour and Boating costs $51 per hour.
Step-by-step explanation:
Let cost per hour of skiing be x and cost per hour of boating be y. Let's dissect the problem into 2 simultaneous equations.
<em><u>"John paid $222 for four hours of skiing and two hours boating":</u></em>
<em><u>"He paid $213 for two hours skiing and three hours boating":</u></em>
<em>Now, if we solve for x in the 2nd equation and plug it in the 1st equation, we will have the value for y</em>. Work shown below.
Hence, y = 51
<em>Now, substituting this y value into the 1st equation and solving for x will give us the value of x.</em>
Hence, skiing costs $30 per hour and boating costs $51 per hour.
