Kaelyn has some yarn that she wants to use to make hats and scarves. Each hat uses 0.20.20, point, 2 kilograms of yarn and each scarf uses 0.10.10, point, 1 kilograms of yarn. Kaelyn wants to make 333 times as many scarves as hats and use 555 kilograms of yarn. Let hhh be the number of hats Kaelyn makes and sss be the number of scarves she makes. Which system of equations represents this situation?

Answers

Answer 1

Answer:

s = 3h

0.1s + 0.2h = 5

h = 10

s = 30

Step-by-step explanation:

Given that :

Hat :

0.2kg of yarn

Let Number of hats = h

Kg of yarn used for hat = 0.2 * h = 0.2h

Scarf:

0.1 kg of yarn

Number of scarves (s) = s

Kg of yarn used for scarf = 0.1 * s = 0.1s

Total kg of yarn used = 5 kg

Number of Scarf = 3 times number of hats :

s = 3h - - (1)

0.1s + 0.2h = 5 - - (2)

From 1:

0.1(3h) + 0.2h = 5

0.3h + 0.2h = 5

0.5h = 5

h = 10

s = 3h

s = 3(10) = 30

What is the value of x in the equation ? (image below)

Answers

Answer: 2

Step-by-step explanation:

2.5(6x-4)=10+4(1.5+0.5x) [Work out the brackets]

15x-10=0+6+2x [Solve]

15x-10=16+2x [Convey the terms]

15x-2x=16+10 [Add up the same terms and calculate]

13x=26 [Divide both parts]

x=2

Answer:

x = 2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

2.5(6x - 4) = 10 + 4(1.5 + 0.5x)

Step 2: Solve for x

Distribute:                                   15x - 10 = 10 + 6 + 2xCombine like terms:                   15x - 10 = 16 + 2xSubtract 2x on both sides:        13x - 10 = 16Add 10 to both sides:                 13x = 26Divide both sides by 13:             x = 2

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    2.5(6(2) - 4) = 10 + 4(1.5 + 0.5(2))Multiply:                               2.5(12 - 4) = 10 + 4(1.5 + 1)Subtract/Add:                      2.5(8) = 10 + 4(2.5)Multiply:                               20 = 10 + 10Add:                                     20 = 20

Here we see that 20 does indeed equal 20.

∴ x = 2 is a solution of the equation.

Answers

268 gallons are remaining. The equation would be y=324-7x, with x being 8. 7(8) is 56, and then you take away 56 from 324, which then gives you 268 gallons remaining

b.) [tex]y=2(x-3)^3+4[/tex]
c.) [tex]y=2(x+3)^3-4[/tex]
d.) [tex]y=2(x-3)^3-4[/tex]

Answers

Answer:

C. y = 2 (x + 3)³ − 4

Step-by-step explanation:

y = x³

Stretch vertically by 2.

y = 2x³

Shift horizontally 3 units to the left.

y = 2 (x + 3)³

Shift vertically 4 units down.

y = 2 (x + 3)³ − 4
