Answer:
X=4
Step-by-step explanation:
First you add like terms, in this case 5x and x. Then you have 6x-1=23. You then add 1 from both sides so you end up with 6x=24. This then results in X=4
Step-by-step explanation:
It is given that Joe paid 14.00 for a board game this is 70% of the original price what is the original price.
Let the original price of board game be
X.
x * 70/100 = 14
x * 7/10 = 14
Multiply both sides by 10.
7x = 140
Divide both sides by 7.
x = 20
Answer:
20.4
96
Step-by-step explanation:
The value of 5x² - 11x + 18 is
5(2.4)²-11(2.4) +18 = 5(5.76) -26.4+18
= 28.8 -26.4+18 = 20.4 (when x = 2.4)
and 5(-3)² -11(-3) +18 = 45+33+18 = 96
(when x = -3)
