Answer:
X = 1h15mins
Step-by-step explanation:
Rate Time Distance
Morgan 20 X 20X
Corona 25 X – ¼ 25(X – ¼)
If they meet each other, they need to travle the same distance, mean :
20X = 25(X – ¼)
X = 1.25
1 hour and 15 minutes
Answer:
A
Step-by-step explanation:
B - 11,015 = 2t ( add 11,015 to both sides )
B = 2t + 11,015 , that is
B(t) = 2t + 11,015
Answer:
y = - 2x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (5, 2) into the partial equation
2 = - 10 + c ⇒ c = 2 + 10 = 12
y = - 2x + 12 ← equation of line
Answer:
0/8
Explanation:
There is no number greater than 10 on the spinner, so there is a 0/8 chance that the spinner will land on a number greater than 10.
-y = x + 3 . . . . this is the sides for the double lines
2y + 24 = x + 9 . . . . this is the sides for the single lines
To solve you need to substitute one equation into the other
-y = x + 3
y = -x - 3 . . . place this equation into the other equation where (Y) is
2y + 24 = x + 9
2 ( -x - 3) + 4 = x +9
-2x - 6 + 24 = x + 9
-2x +18= x+9
-3x = -9
x = 3 . . . substitute this answer into the equation and solve for (Y)
-y = x + 3
- y = 3 +3
-y = 3 + 3
y= -6
