Answer:
Equation of the line that passes through the point (-2,7) and has a slope of zero is given as
Step-by-step explanation:
Equation of line is given as
-----------(1)
Here
Substituting values in equation (1)
Step-by-step explanation:
white=26
1/4+1/8+1/12=6/24+3/24+2/24=11/24=(green,blue and yellow marbles)
24-11=13/24=white
26/13=2=1/24
blue=3/24
2.3=6
answer 6
There are 13 hearts in a 52 deck.
You can think about it like this:
P = (13/52)*(12/51)*(11/50)*(10/49)*(9/48)*(8/47) = 0.00008428903476
Answer:
Gabby received
7 nickels
10 dimes
3 quarters
Step-by-step explanation:
Let
x----> the number of dimes
y----> the number of nickels
z---> the number of quarters
Remember that
1 dime=$0.10
1 nickel=$0.05
1 quarter=$0.25
we know that
0.10x+0.05y+0.25z=2.10 ------> equation A
x=y+3-----> equation B
z=y-4 -----> equation C
substitute equation B and equation C in equation A and solve for y
0.10(y+3)+0.05y+0.25(y-4)=2.10
0.10y+0.30+0.05y+0.25y-1=2.10
0.40y=2.10-0.30+1
0.40y=2.80
y=7 nickels
<em>Find the value of x</em>
x=y+3 -----> x=7+3=10 dimes
<em>Find the value of z</em>
z=y-4 -----> z=7-4=3 quarters
therefore
Gabby received
7 nickels
10 dimes
3 quarters
