Answer 1

1)

2x - 3y = - 1

For y = x - 1

So,

2x - 3y = - 1, Subsitution

2x - 3(x - 1) = - 1

2x - 3x + 3 = - 1

- x + 3 = - 1

- x = - 1 - 3

- x = - 4

x = 4 ✔

y

y = x - 1

y = 4 - 1

y = 3 ✔

So => HP = {x, y} = {4, 3}

Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?

Answers

Answer:

He spent $24 dollars

Step-by-step explanation:

Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars

Step-by-step explanation:

Number of gluten-free flour used for 5 pies= 2×5= 10 cups

cost of 4 cups of gluten-free flour = $12

cost of 1 cup = 12/4 = $3

Then,

cost of 10 cups of gluten-free flour = 3×10

= $30

Answers

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6

A recursive rule allows a term to be found by adding d to the previous term, thus

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6 with a₁ = - 17

Trisha’s parents bought a new house that has 2,255 square feet.
The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.

Answers

Answer:$220,290

Step-by-step explanation:

2,255 multiplied by 98 is 220,290

The total cost of Trisha’s parents new house is $220990.

Given that, Trisha’s parents bought a new house that has 2,255 square feet.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The price per square foot was $98.

So, the total cost of house = Number of square feet × The price per square foot

= 2,255 × 98

= $220990

Therefore, the total cost of Trisha’s parents new house is $220990.
