Answer:
x=1/6
Step-by-step explanation:
1/2-1/3=x
x=1×3-1×3/6 [ take l.c.m]
x=3-2/6
x=1/6 .
Answer:
P(yellow the red) = 
Step-by-step explanation:
P(yellow and red) = P(yellow then red) + P(red then yellow)
P(yellow then red) = 
P(red then yellow) = P(yellow then red)
P(yellow and red) = 
739 is less than 750, your answer is 248,700 because 739 is closer to 700 than it is to 800.
Three. x, y, and z. terms are the total different variables, not the total number of variables.
Answer:
Tiffany has 13 dimes and 4 nickels.
Step-by-step explanation:
To solve this problem, you will need to write a systems of equations, n will be the number of nickels and d will be the number of dimes.
n+d=17 This means that the number of nickels plus the number of dimes is equal to 17.
5n+10d=150, This means that for each nickel, there is 5 cents and for each dime, there is 10 cents. The equation is equal to 150 cent because the coins are worth 150 cents.
Next, solve the system:
n+d=17
5n+10d=150 First simplify the second equation by dividing it all by 5.
n+d=17
n+2d=30, Next, isolate n to use substitution on the system.
n=17-d
n=30-2d, Substitute n to solve for d
17-d=30-2d, Solve for d
d=13, this means that there are 13 dimes, plug in the d value in either of the equations to find n.
n+(13)=17
n=4, There are 4 nickles
