Answer:
17.50
Step-by-step explanation:
you really don't need to know the tax amount.
20% of x = 3.50
(20/100) x = 3.50 Divide top and bottom of the left number by 20
(20÷20) / (100÷20) * x = 3.50
(1/5) x = 3.50 Multiply both sides by 5
x = 3.50 * 5
x = 17.50
The meal cost 17.50

Answer:
the answer is the second choice
Step-by-step explanation:
2 steps right and 5 up in mathematics is written as:
x->x+2 and y->y+5
For instance, in the point L
(-5,-2) --> (-5+2,-2+5)=(-3,3)
which is L'=(-3,3)
and so on.
Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
5.0625
Step-by-step explanation:
Step 1:
The given expression can be written as
![135X + 120 + 3X + 31 + 4X + 15+ 6X -8 +7X-64 +5X-4 =900](https://tex.z-dn.net/?f=135X%20%2B%20120%20%2B%203X%20%2B%2031%20%2B%204X%20%2B%2015%2B%206X%20-8%20%2B7X-64%20%2B5X-4%20%3D900)
On solving the above expression
adding all the X terms and constant terms individually
160X + 90 = 900
Step 2:
160X = 810
X = (810/160) =5.0625
