Answer:
See explanation
Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.
Answer:x=6 y=-58
Step-by-step explanation:I hope i help you,have a nice day.
Tenths would be on the right of an decimal. So 2 tenths would equal "0.2". 3 copies would be adding "0.2" 3 times. So 0.2 + 0.2 + 0.2 = 0.6

3 5
------- + ------- = 0
8 12
In adding fractions.
Step 1: make sure the denominators are the same. 8 and 12 are not the same. But both are factors of 24.
8 * 3 = 24
12 * 2 = 24
Multiply both numerator and denominator of 3/8 by 3 and 5/12 by 2.
3 * 3 5 * 2 9 10
--------- + ------------- = -------- + ---------
8 * 3 12 * 2 24 24
Step 2. Since the denominator is now the same, add the numerator and put it over the denominator.
9 + 10 19
---------- = -------
24 24
Step 3. Simplify the fraction.
19
----
24 is already the simplified form.
