The x is the variable so you have to find what the equation equals in order too find out what variable x is. 2 x7+2 = 16. So now x = 16
Distribute the 9 to each term in the parentheses with multiplication.
9(3 + x) = 27 + x
But this is usually written as x + 27
Answer:
$ 74.80
Step-by-step explanation:
The subtotal cost of the meal was $91.22 including tax.
The 18% tip is added for six or more.
The tip added should reduce the meal subtotal by 18 %
Reduce $91.22 by 18% to get ;
82/100 * 91.22 = $ 74.80
The answer is A) 6:15, because if you divide both numbers by three, it'll give you 2:5
sum of all sides of triangle=180°
7x+13x+16x=180°
36x=180°
x=180°/36
x=5
angle D=7x
=7(5)
D=35°
angle E=13(x)
=13(5)
E=65°
angle F=16x
=16(5)
F=80°
angle D=35°
angle E=65°
angle F=80°
