Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
Answer:
h>13
Step-by-step explanation:
Answer:
no rain today = 35%
Step-by-step explanation:
In probability, the Complement Rule states that the sum of the probability of an event and its complement must = 1
i.e
P( Event) + P (Complement) = 1
In this sense, we can think of the complement of an event as the "not-event". I.e the event does not happen.
In our case, the event = "rain today",
hence the complement will be = "not rain today" (i.e no rain today)
using the formula above, we are given that P(rain today) = 65% = 0.65
hence
0.65 + P(Complement) = 1
P(Complement) = 1 - 0.65 = 0.35 = 35%
The answer is P = 2(l+w) units.
This is because when you let the perimeter of the rectangle be P, the length of the rectangle be l and the width of the rectangle be w.
The information above can be expressed as the following equation,
P = 2l + 2w
You can then factorise out the common factor, 2.
P = 2(l+w)
Thus, the answer is P = 2(l+w) units.
Answer is X > 18
1. Group all constants on the right side of the inequality
X/3 - 2 > 4
Add 2 to both sides: x/3 - 2 + 2 > 4+2
Simplify the arithmetic: X/3 > 4 + 2
Simplify the arithmetic: X/3 > 6
