Answer:
Hotdog costs $5.35 each and hamburger costs $0.18 each
Step-by-step explanation:
The difference in price between the two is the cost of 5 hotdogs.
So, $56.25 - $29.50 = $26.50
I hotdog would cost $26.50/5 = $5.35
Substituting the cost of one hotdog,
10($5.35) + 15ham = $56.25
$53.50 + 15 ham = $56.25
15 ham = $56.25 - $53.50
15 ham = $2.75
So, 1 ham = $2.75/15
= $0.18
Answer:
If a person is randomly selected from this group, the probability that they have both high blood pressure and high cholesterol is P=0.25.
Step-by-step explanation:
We can calculate the number of people from the sample that has both high blood pressure (HBP) and high cholesterol (HC) using this identity:

We can calculate the probability that a random person has both high blood pressure and high cholesterol as:

Answer:
161
Step-by-step explanation:
Answer:
Time = distance/speed. T = 1,200,000,000/28,000. This can be cancelled to 1,200,000/28. Rounding 28 to 30 for the estimate, divide by another ten: 120,000. Then divide by the remaining 3 from 30: 120,000/3 = 40,000. It will take approximately 40,000 hours.

Answer:
The algebraic expression which represents the phrase “two times the quantity of a number minus 12” is : 2x- 12
Step-by-step explanation:
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
for example :-
3x + 4y – 7, 4x – 10, etc.
These expressions are represented with the help of unknown variables, constants and coefficients. The combination of these three (as terms) is said to be an expression. It is to be noted that, unlike the algebraic equation, an algebraic expression has no sides or equal to sign
let the quantity mentioned in the question be 'x'
therefore according to the statement the algebraic expression which represents the phrase “two times the quantity of a number minus 12” is : 2x- 12 is
⇒2x - 12 (answer)
