If you do 20 + 5x = 70, that'll give you the total hours (x)
70-20 = 50,
5x = 50
Divide each by 5,
x = 10
Answer:
The value of 
Step-by-step explanation:
The graph of 
in attachment.
Using graph to find the value of x such that y<0
y<0, It means all the values of y are negatives.
As we know, negative value of y always below x-axis.
In the graph, we can see between -3 to -1 graph shown below x-axis.
Therefore, all the values of y as 
are negatives.
Hence, the value of
Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
Hello!
We know that Isaac played 20 games and won about 70% of them. Now, we must find what 70% of 20 is, so that we know how many games Isaac won.
First, convert the percentage to a decimal by dividing it by 100.
70% ÷ 100 = 0.70
Next, multiply the total amount of games Isaac played (20) by about how many he won (0.70):
20 × 0.70 = 14
ANSWER:
Isaac won about 14 games.
