Answer:
10 games
Step-by-step explanation:
Let C be cost and x be number of games
Arcade A: C = 5 + 0.6x
Arcade B: C = 7 + 0.4x
for both arcades to be the same price, Both C's must be equal, hence we equate the right side of both equations:
5 + 0.6x = 7 + 0.4x (subtract 5 fromboth sides)
0.6x = 7 + 0.4x - 5
0.6x = 2 + 0.4x (subtract 0.4x from both sides)
0.6x - 0.4x = 2
0.2x = 2 (divide both sides by 0.2)
x = 2 / (0.2)
x = 10
I think it’s C
Explanation: the blue yarn is 7 and the red yarn is 10 if you combine both as 7 + 10= 17
YES IT IS!!
Work:
EQ: y= -x + 4
x= -6
y= 10
y= -x+4
1. 10= -(-6)+4
2. 10= +6+4
3. 10= 10
Answer:
4.7953 x 10⁻¹⁹ m³
Step-by-step explanation:
Length of the Escherichia coli cell (L) = 2.65 x 10⁻⁶ m
Diameter of the Escherichia coli cell (D) = 0.480 x 10⁻⁶ m
The volume of cylinder in given by:
The volume of an E. coli cell is 4.7953 x 10⁻¹⁹ m³.
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
