.Daniella has two jobs. She earns $7 per hour babysitting her neighbor's children and she earns $12 per hour working at the coffee shop. Write an inequality to represent the number of hours babysitting (x) and the number of hours working at the coffee shop (y) that Daniella will need to work to earn at least $200.

Answers

Answer:

The inequality to represent this scenario is given as:

7x + 12y ≥ 200

Step-by-step explanation:

From the question:

Daniella has two jobs. She earns $7 per hour babysitting her neighbor's children and she earns $12 per hour working at the coffee shop.

Let:

The number of hours babysitting = (x) The number of hours working at the coffee shop= (y)

We are told in the question that:

Daniella will need to work to earn at least $200.

At least means equal to or greater than

Hence,

The inequality to represent this scenario is given as:

$7 × x + $12 × y ≥ $200

7x + 12y ≥ 200

The local ice cream shop surveyed their costumers to see wich flavor of ice cream is most popular.125 people chose chocolate as their favorite flavor,wich represents 25% of the costumers surveyed.How many total costumers were surveyed?

Answers

Answer: The total costumers were surveyed = 500

Step-by-step explanation:

Let x = total costumers were surveyed.

Given : 125 people chose chocolate as their favorite flavor, which represents 25% of the costumers surveyed.

25% of x = 125

[tex]\Rightarrow\ \dfrac{25}{100}\times x = 125\\\\\Rightarrow\ \dfrac{1}{4}x=125\\\\\Rightarrow\ x=125\times4\\\\\Rightarrow\ x= 500[/tex]

Hence, the total costumers were surveyed = 500

how to solve using Substitution or Elimination?
y=3x-1

y=2x+2

Answers

By elimination:

y = 3x - 1

y = 2x + 2

Subtract the second equation from the first

0 = x - 1

y = 2x + 2

Subtract the first equation from the second

0 = x - 1

y = x + 3

Subtract the first equation from the second again

0 = x - 1

y =      4

Subtract x from both sides of the first equation

- x =  - 1

y =      4

Divide the first equation by (-1)    

x =  1

y =  4

So, the solution is  x = 1  and  y = 4   {or: (1, 4)}

Step-by-step explanation:

Layla emptied out her change jar to buy a new binder for school. She found 147 coins consisting of dimes and nickels that totaled $11.65. Write a system of equations that could be used to determine how many dimes, d, and how many nickels, n, Layla had in her change jar.

Answers

Answer:

d + n = 147

0.10d + 0.05n = 11.65

d = 86, n = 61

Step-by-step explanation:

Let

Number of dimes = d

Number of nickels = n

Total coins = 147

Total value = $11.65

d + n = 147 (1)

0.10d + 0.05n = 11.65 (2)

From (1)

d = 147 - n

Substitute d = 147 - n into

0.10d + 0.05n = 11.65

0.10(147 - n) + 0.05n = 11.65

14.7 - 0.10n + 0.05n = 11.65

- 0.10n + 0.05n = 11.65 - 14.7

-0.05n = -3.05

n = -3.05 / -0.05

= 61

n = 61

Substitute n = 61 into

d + n = 147

d + 61 = 147

d = 147 - 61

d = 86

The sum of two numbers is 59 and the difference is 21. What are the numbers?
Larger number:
Smaller number: 0
2.

Answers

Answer:   The larger number is 40.

The smaller number is 19

Step-by-step explanation:

x + (x-21) = 59   This is the number and the  number difference add to 59.

x + x = 59 + 21    Add 21 to both sides. Combine like terms.

2x = 80  divide both sides by 2

x= 40 This is the first number.  Subtract 21 to get the second number

40 - 21 = 19

The difference between 40 and 19 is 21.

19 + 40 = 59

Answers

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x  +5       -x   +5

25/3 = 3x/3

x = 25/3

Since these equations are consecutive interior angles, they will add up to 180.
The equation will be (x+20)°+(4x-5)°=180.

(x+20)+(4x-5)=180
5x+15=180
5x=165
165/5x
=33°

You can make sure your answer is correct by putting your x back into the equation.
