Given :
a restaurant customer left a $1.95 as a tip.
The tax = 5%
the tip was 15% of the after-tax cost
So, the information that not needed is the tax
Let the total bill = x
so, 15% of x = 1.95
so, the total bill = $13
If angle ABC is 90°, then angle CBD is 90°:
Angle ABD=90°
3x°=90°
3x=90
Solving for x:
3x/3=90/3
x=30
Angle CBD=90°
(2x+3y)°=90°
2x+3y=90
x=30
2(30)+3y=90
60+3y=90
Solving for y:
60+3y-60=90-60
3y=30
3y/3=30/3
y=10
Answer: Option a. 10
Hello there!
4³ + 2(3 - 2)
= 64 + 2(1)
= 64 + 2
= 66
The correct answer is option C
The second part*
A variable cubed >>>>> x³
Quotient of some number and three >>> b ÷ 3
Product of an unknown value and three >>>>> 3a
Three less than a variable >>>y - 3
Three more than some number >>>> z + 3

The ratio in which Adm, Ming and Clinton sold sandwiches = 4:7:3
Number of sandwiches sold by Ming = 91
Let us assume the common ratio to be = x
Then
7x = 91
x = 91/7
= 13
Then
The number of sandwiches sold by Adm = 4 * 13
= 52
The number of sandwiches sold by Clinton = 3 * 13
= 39
So
The total number of sandwiches
sold by Adm, Ming and Clinton = 52 + 91 + 39
= 182.
So a total of 182 sandwiches were sold by Adm, Ming and Clinton.
