Answer is b I just did it
Answer:
1) 7m
2) 13
3) 4x^2y
4) 6s^3t^4
Step-by-step explanation:
gcf means the the greatest factor that works for both terms
1) 21m^3 and 28m
let's first find the gcf for the coefficient
21 and 28, the gcf is 7. (hopefully thats easy to explain)
the gcf for the variables is the same mindset as the numbers
m^3 and m, both can be factored by m
so the gcf is 7 * m which is 7m
2)
13x and 26
let's first find the gcf for the coefficient
13 and 26, gcf is 13
there's only one variable, x, so there's not gcf for that
so the gcf is just 13
3)
8x^2y and -12x^3y^2
let's first find the gcf for the coefficient
8 and -12, the gcf is 4 (you can also say -4)
for the variables , same mindset
x^2y and x^3y^2
the gcf for x is x^2, and for y it is just y
so 4 * x^2 * y = 4x^2y
by understanding 3) hopefully you can understand 4)
pls comment for any questions

Answer:
Treat the numbers separately and powers separately.
Multiply the two results at the end.
Example:
(2×10⁵) ÷ (4×10²)
(2 ÷ 4) × (10⁵ ÷ 10²)
0.5 × 10³
5.0 × 10²
Answer:
Sue played 30 games
Step-by-step explanation:
Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:
Cross multiply: 4x = 120
Divide by 4: 4x/4 = 120/4
Solve for 'x': x = 30 games
