Step-by-step explanation:
Answer:
Explanation below.
Step-by-step explanation:
Let's say for example you have 100 dollar or euros, or whatever you work with in your country. 30% of 100 equals 30.
If they ask you for example 30% of 250 dollar/euro, it is 250/100 * 30, which equals 75.
If they say there are sales that go up to 30%, all you do is as follows;
1) You calculate how much money 30% is. [Look above]
2) You distract the 30% FROM the original price.
Example; A shirt costs 300 dollar/euro, but there's a sale of 30% on it.
30% of 300 = 100
300-100 = 200
The shirt costs 200 dollar/euro.
Answer:
5 + (-5) and 8 + (-8)
Step-by-step explanation:
Sum of zero means when you add them you get 0
so the others are wrong
-5 + (-5) = -10 because you have -5 and you add another -5
-12 + (-12) = -24 you start with -12 and you add another -12
Think of positive and negative numbers like floors in a building. Positive numbers are the stories and the negative numbers are the basement and sub-basement, zero is the ground level. So for 5 + (-5) you go up 5 floors, then you go down 5 floors. you end up on the ground level, 0.
Answer:
The number of hours Stephanie will have driven before Tina catches up to her is 2.5 hours
Step-by-step explanation:
Given:
56s=70t
s=t+1/2
Solution
56s=70t
s=t+1/2
Substitute s=t+1/2 into 56s=70t
56s=70t
56(t+1/2)=70t
56t+28=70t
28=70t - 56t
28=14t
Divide both sides by 14
28/14=14t/14
2=t
t=2
Recall,
s=t+1/2
s=2+1/2
=4+1/2
s=5/2
Or
s=2.5 hours
11 + q = -15, simple as that.
