Divide both sides by the negative so you’ll get y= -x.
Answer:
x = -7
Step-by-step explanation:
3(x+7) = -15
First, distributive property. Therefore, you multiply 3 with x and 7
3x + 21 = -15
Then, you need x to be isolated. So you will have to -21 from +21 on both sides of the equation to make it balanced.
3x + 21 = -15
<u> -21 -21</u> (21 will be canceled from the left side of the equation)
3x = -35
Lastly, you need to divide 3 from both sides of the equation, as 3 is multiplied with x.
<u>3x</u> = <u>-35</u>
3 3 (3 will be canceled from the left side of the equation)
<em><u>x = -7</u></em>
Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.
