Given:
4 1/7 * 3 3/5
4 1/7 = (4*7)+1/7 = 29/7
3 3/5 = (3*5)+3/5 = 18/5
29/7 * 18/5 = 29 * 18 / 7 * 5 = 522 / 35 = 14.91
Simplified expression.
4 x 3 1/2
3 1/2 = (3*2)+1/2 = 7/2
4 * 7/2 = 4*7 / 2 = 28 / 2 = 14
It is a close estimate. Actual: 14.91 vs Estimate: 14
Answer:
y = x - 2 could not be the function equation.
Step-by-step explanation:
The function with an input of 3 has an output of 5.
So, y = 2x - 1 can be the function as y(3) = 2 × 3 - 1 = 6 - 1 = 5.
Now, y = x + 2 can also be the function as y(3) = 3 + 2 = 5
Again, y = 3x - 4 can also be the function as y(3) = 3 × 3 - 4 = 9 - 4 = 5
But y = x - 2 can not be the function as y(3) = 3 - 2 = 1 ≠ 5
Therefore, y = x - 2 could not be the function equation. (Answer)
Answer:
v = how many students fit into a van
b = how many students fit into a bus
School A:
11v+10b=629
School B:
14v+10b=656
Since both classes used 10 buses, we can use elimination by subtracting the A class equation from the B class equation and solve for v, for its value. Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be:
14v%2B10b-%2811v%2B10b%29=656-629, which shows the van holds only a few people even before continuing the solution. (Looks like 9 students fit in a van.)
