Carlos has $24, which is 1 1/3 as much money as Luisa has. How much money does Luisa have?
Answer:
Luisa has $18
Step-by-step explanation:
Let us solve the question
∵ Carlos has $24
∵ Carlos has 1 [tex]\frac{1}{3}[/tex] as much money as Luisa has
→ Let Luisa has x dollars
∵ Luisa has x dollars
∴ Carlos money = 1 [tex]\frac{1}{3}[/tex] × x
∴ Carlos money = 1 [tex]\frac{1}{3}[/tex] x
→ Change the mixed number to an improper fraction
∵ 1 [tex]\frac{1}{3}[/tex] = [tex]\frac{1(3)+1}{3}[/tex] = [tex]\frac{4}{3}[/tex]
∴ Carlos money = [tex]\frac{4}{3}[/tex] x
→ Substitute the Carlos money by 24
∵ 24 = [tex]\frac{4}{3}[/tex] x
→ Multiply both sides by 3
∵ 24 × 3 = 4x
∴ 72 = 4x
→ Divide both sides by 4
∴ 18 = x
∴ Luisa has $18

the equation y=3x-6 and the table shown below describe two different linear functions. Which function has the greatest rate of change? Explain
Answer:
The rate of change would be y^2-y^1/x^2-x^1. So in this cause the answer is 10.5/3.

A grandma has three grandchildren.Sara, Whitney, and Hannah. Whitney is 3 years younger than Sara. Hannah is half as old as Whitney. Hannah's age pplus Whitney's age equals Sara age. How old is each granddaughter? Let x = Whitney's age in years
Answer:
Whitney = 6
Sara = 9
Hannah = 3
Step-by-step explanation:
Let :
Whitney = x
Sara = x + 3
Hannah = x / 2
Hannah's age + Whitney's age = Sarah's age
x / 2 + x = x + 3
1.5x = x + 3
1.5x - x = 3
0.5x = 3
x = 3/0.5
x = 6
Whitney = 6
Sara = x +3 = 6 + 3 = 9
Hannah = x/2 = 6/2 = 3

Transversal t intersects lines d and e to form 8 angles. The angles formed with line d, clockwise from top left are 1, 2, 7, 8. The angles formed with line e, clockwise from top left are 3, 4, 5, 6. Which angle is an alternate exterior angle to ∠8? ∠3 ∠4 ∠5 ∠6
9514 1404 393
Answer:
angle 4
Step-by-step explanation:
"Alternate" means the angles are on opposite sides of the transversal. "Exterior" means the angles are outside (not between) the parallel lines. The diagram shows the alternate exterior angles are angle 8 and angle 4.
Please help! my question is in english, please look at my profile :) i know more people look at mathematic questions so thats why im putting this here, thank you
Answer:
i'll see if i can solve it! :)
Step-by-step explanation:
Two experiments are conducted to determine the mass of an object.
-In Experiment 1, you place the object on an electronic balance and read the object's weight.
-In Experiment 2, you apply a constant force to pull the object along a horizontal surface, while using a motion detector to measure the object's speed as it is pulled.
All frictional forces for both experiments are considered to be negligible. Which of the two experiments, if either, could be used to determine the gravitational mass of the object?
a. Experiment 2 only
b. Experiment 1 only
c. Neither experiment
d. Both experiments
Answer: Experiment 1 could be used to check the gravitational mass of an object.
Step-by-step explanation: Gravitational mass can be described as the strength which the gravitational force has on an object when it is present in the gravitational force. An object at rest will experience only the gravitational force. Whereas an object that is pulled along a horizontal surface with a spring scale will have other forces acting on it along with the gravitational force.
To check for the gravitational mass, an object should only have a gravitational force acting upon it. Hence, experiment 1 is the correct option.
