It is number 1 and number 2 because the equation is 242× 62 and Number 1 and 2 are just breaking it down
Answer:
I think the answer is A, though i can be wrong
Step-by-step explanation:
Answer:
1.21 kilograms
Step-by-step explanation:
Let y represent the mass of the empty basket, and x represent the mass of each ball
Create a system of equations:
3x + y = 3.64
5x + y = 5.26
Solve by elimination by multiplying the top equation by -1
-3x - y = -3.64
5x + y = 5.26
Add them together, then solve for x:
2x = 1.62
x = 0.81
Plug this back into one of the equations and solve for y:
3x + y = 3.64
3(0.81) + y = 3.64
2.43 + y = 3.64
y = 1.21
So, the mass of the empty basket is 1.21 kilograms
7.5 x 10^3/5 x 10^-2
7.5/5 * 10^(3-(-2)) divide the numbers subtract the exponents
1.5 *10^5
Here you go :) I sent the work in the picture below
