Always look to the left of the number if there's a minus sign then it's negative. If it has nothing or a plus sign, then it is positive.
9) x= -7
10) x= 10
11) x= 5
12) x= 6
13) x= 4
14) x= -9
15) x= 3
16) x= 9
sorry it took so long! hope this helps!! :)
Hi!
To find this math problem your going to need to use a^2 + b^2 = c^2 (^2 means squared)
So if we look at the shape , they entire shape makes for triangles . (I'm going to be using the upper right triangle to solve this problem just so your following me)
So one side of the "triangle" is 6 and that's like the bottom of the triangle . And your hypotenuse is 10.
So using that formula , plug in 6 and 10 so we can find the other missing side
a^2 + 6^2 = 10^2
A^2 + 36 = 100
100-36 = 64
SQAURE ROOT of 64 = 8
Your missing side length is 8
8 + 8 = 16
DB= 16. ( you have to add them together to get the full length)
I hope this helps you :)
Answer:
0.003
Step-by-step explanation:
Given: A roulette wheel consists of 38 numbers 1 to 36, 0, and double 0.
Smith bets that the outcome will be one of the numbers 1 through 12.
To find: probability that Smith will lose his first 5 bets
Solution:
Probability refers to chances of occurrence of some event.
Probability = Number of favourable outcomes/Total number of outcomes
Total number outcomes = 38
As Smith bets that the outcome will be one of the numbers 1 through 12, number of favourable outcomes is equal to 12.
So,
probability that Smith will loss his first bet = 
Therefore,
Probability that Smith will lose his first 5 bets = 
Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
