Two ice cream shops in the mall sell sundaes. Let x equal the number of scoops of ice cream. Larry's Ice Cream Shop's price is represented by the expression 1.2x + 1. Ice Cream World's price is represented by the expression 0.4(0.3x + 1) . Which statement is true?
Choose the correct answer below.
A.
The two shops charge the same price for a 3-scoop sundae.
B.
The two shops charge the same price for a 2-scoop sundae.
C.
The two shops never charge the same price for sundaes with the same number of scoops.
D.
The two shops always charge the same price for sundaes with the same number of scoops.
Answers
Answer:
the answer is D.
Step-by-step explanation:
this is because if you distribute 0.4 times 0.3 you get 0.12.
then you are left with 0.12+1 which means both shops charge the same price.
Which of these expressions is equivalent to -2(x - 5)?
-2x + 5
-2x - 10
-2x + 10
-2x-5
Question 3
Mathematics
Answers
When doing the distributive property, multiply -2 and x to get -2x. Then, multiply -2 and -5(remember when you multiply a negative with a negative, you get a positive number) to get 10. Therefore your answer would be -2x+10.
Hope this helps!
The equivalent expression is: -2x + 10. therefore the correct option is C.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
From the distributive property;
-2(x - 5)
Then, multiply -2 and -5
-2 * x = -2x
-2 * -5 = 10
because two negatives make a positive
Therefore the answer would be -2x+10.
Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.

A car salesman gets paid $3,750 each month plus 8.5% commission on his total sales. This month he sold 5 cars for a total of $138,000. What are his monthly total earnings?
Answers
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let y represent the total money the salesman earns for selling a total of $x sales. Hence:
y = 0.085x + 3750
If the salesman makes a total of $138000, hence:
y = 0.085(138000) + 3750
y = 15480
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet
Answers
Answer:
v = 22.5 miles/hour
Step-by-step explanation:
It is given that,
The speed of Penguins is 33 ft/s.
We need to convert the speed to miles per hour.
We know that, 1 mile = 5280 feet
Speed,
[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]
So, the speed of the Penguins is 22.5 miles/hour.

What is a system of equations?A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.
Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.
If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

express the ratio 60cm to 20m
Answers
Answer:
3 cm : 1 cm
Step-by-step explanation:
1. 60 : 20
2. divide 10 on both sides = 6 : 2
3. divide by 2 on both sides = 3 : 1
4. 3 cm : 1 cm
I'm so sorry, I just read the ratio is 60 cm to 20 M
So edit:
convert both into a unit, we'll take m.
1 cm = 100 m
so 60 x 100 = 60000 m
= 60000 m : 20 m
= divide by 20 in both sides...
= 3000 m : 1 m
