Answer:
x=1/2. y=4
Step-by-step explanation:
4(2x+3y=13)=8x+12y=52
2(4x-y=-2)=8x-2y=-4
subtract equation one from equation two to get
14y=56 then u will divide bothe sides by 14. for x u substitute y in equation one
Answer:
4 times 312 = 1,248 = 312 times 4 = 1,248

Answer:
The answer to your question is 7.8 mi
Step-by-step explanation:
Data
H (4,3)
G (10, 8)
Process
1.- Use the distance between to points formula to find the distance
dHG = 
x1 = 4 y1 = 3
x2 = 10 y2 = 8
2.- Substitution
dHG = 
3.- Simplification
dHG = 
dHG = 
dHG = 
4.- Result
dHG = 7.8 mi
Answer:
She should win approximately 30 times.
Step-by-step explanation:
Since the probability of winning is 3/8, we multiply 3/8 with 80 to get 30.
The possible values of N from the given probability parameters is; N equals 15 or 21
<h3>How to Solve Algebra Problems?</h3>
We are told that;
Number of pens in the box = N
Let the number of red pens be x
Thus; number of black pens = x + 3
Thus;
x + x + 3 = N
x = (N - 3)/2
The probability that she will take a black pen followed by a red pen is;
P(she will take a black pen followed by a red pen) = (x + 3)/N * x/(N - 1)
Plugging in he relevant values and solving for N gives ;
Solving for N gives N equals 15 or 21
