Answer: The correct answer is Kayden- 6 cookies; Kayah-9 cookies; Michelle-9 cookies and Kayla- 12 cookies

Step-by-step explanation: There are 36 cookies. Kayden gives $2-  or pays for 1/6 of the cookies (2/12= 1/6) The decimal for 1/6 is 0.16, so 36 x 0.16= 5.88 rounded up to 6 cookies. Kayah contributed $ 3- or pays for  1/4 of the cookies. (3/12= 1/4) The decimal for 1/4 is 0.25, so 36 x 0.25= 9, so Kayah and Michelle each get 9 cookies. Kayla gives $4- or pays for 1/3 of the cookies (4/12= 1/3) The decimal for 1/3 is 0.33, so 36 x 0.33= 11.88 rounded to 12.

Solve. State the number of solutions.
Oksi-84 [34.3K]

Answer:

a. x=8

b.Step 1: Simplify both sides of the equation.

2(2x−2)=4x−4

(2)(2x)+(2)(−2)=4x+−4(Distribute)

4x+−4=4x+−4

4x−4=4x−4

Step 2: Subtract 4x from both sides.

4x−4−4x=4x−4−4x

−4=−4

Step 3: Add 4 to both sides.

−4+4=−4+4

0=0

Answer:

All real numbers are solutions.

c. Step 1: Simplify both sides of the equation.

3(x+1)=4x+7−x

(3)(x)+(3)(1)=4x+7+−x(Distribute)

3x+3=4x+7+−x

3x+3=(4x+−x)+(7)(Combine Like Terms)

3x+3=3x+7

3x+3=3x+7

Step 2: Subtract 3x from both sides.

3x+3−3x=3x+7−3x

3=7

Step 3: Subtract 3 from both sides.

3−3=7−3

0=4

In 1985, the cost of clothing for a certain familiy was $620. In 1995, 10 years later, the cost of clothing for this famility wa
Sholpan [36]

Answer:

$848

Step-by-step explanation:

Calculation for the cost of this familiy's clothing in 1991

First step is to calculate the amount that is increase per year

Increase per year= ($1000-$620)/(1995-1985)

Increase per year= 380/10

Increase per year= $38

Now let y be :38*x + $620 and let x be 6 years (1991-1985)

Second step is to calculate the cost of the clothing in 1991

y = 38*6 + 620

y=228+620

y = $848

Therefore the cost of this familiy's clothing in 1991 will be $848
