Answer:
yes, the meal costs 25.60
Step-by-step explanation:
I used a slightly different method but B (Yes. They have enough to pay their bill: 21 dollars times 1.06 = 22 dollars and 26 cents and 22 dollars and 26 cents times 1.15 = 25 dollars and 60 cents.) is correct.
21*0.06=1.26
1.26+21=22.26
22.26*0.15=3.34
22.26+3.34=25.60

Answer: The answer is 84 inches.
Step-by-step explanation: It is given that twelve round gold medals fit inside a box where 4 medals are placed in one ray. So, the number of rows in the box is 3.
The radius of each gold medal = 3 inches.
Therefore, diameter of each gold medal = 2 × 3 = 6 inches.
The box is obviously in the rectangular form where
The red tape fits snugly around the sides of the box, so it will cover whole of the box.
Therefore, the length of the tape = 24+18+24+18 = 84 inches.

Answer:
<h2>30</h2>
Step-by-step explanation:
<h3>to understand the steps</h3><h3>you need to know about:</h3>
- system of linear equation
- word problems
- PEMDAS
first step
let's create the equation word problem
<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>
let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30
