N(-5/8)=-0.4
times both sides by -8/5
n(-40/-40)=3.2/5
n1=0.64
n=0.64
The difference is that evaluating an expression for a given value is an example of let’s say In a example, the variable x is equal to 6 since 6 + 6 = 12. So it means that they are giving you the input already. SOLVING an equation is working backwards, to undo everything that has been done to the input. So you have to do the equation in order to find your answer.
Answer:
10 %
Step-by-step explanation:
15 mn = 1/4 h
We have :
Then the percentage that 15 mn represents of 5/2 h is :
0.1 × 100 = 10 %
X² - 10x = 46
10/2 = 5; 5²+ 25 add 25 to both sides
x² - 10x + 25 = 46 + 25
so the number you have to add to complete the square is 25.
Answer:
6x ≥ 500
Step-by-step explanation:
I took the test but also it means that in six months, you have to save that amount of money to get exactly or more than 500, so this would be the correct answer!
