Answer:
The percent increase is 250 percent
Step-by-step explanation:
To find the percent increase we use the formula
percent increase = (new-original)/original * 100
= (35-10)/10 * 100
= 25/10 *100
250
The percent increase is 250 percent
-1 in decimal form is -1.0, just as 5 in decimal form, for example, is 5.0. Just copy the negative sign.
2(4z−2) = 44
Simplify both sides of the equation.
Distribute:
(2)(4z)+(2)(−2) = 44
8z + −4 = 44
8z − 4 = 44
Add 4 to both sides.
8z − 4 + 4 = 44 + 4
8z = 48
Divide both sides by 8
8z/8 48/8
z = 6
Order the numbers smallest to largest and go to the middle, the middle number is your answer :)
