can someone do b and c? or just one

Answers

b) 4(x+2) + 8(x-1)

first we distribute the 4

4x+ 8 + 8(x-1)

now we distribute the 8

4x+8 + 8x-8

now we combine the 4x and the 8x because they have the same variable so they are like terms

12x +8-8

the 8 cancels out so

b) 12x

now c)

3(w-5) - 6(w+2)

distribute 3

3w-15 - 6(w+2)

now distribute -6

3w-15 -6w -12

combine 3w and -6w because they are like terms

-3w -15-12

now combine -15 and -12

answer to c: -3w-27

In the diagram below of triangle ABC, D is a midpoint of AB and E is a midpoint
of BC. If m of ZCAD?

Answers

Answer:

The measure of ∠CAD is 69°

Step-by-step explanation:

In ΔABC

∵ D is the mid-point of AB

∵ E is the mid-point of BC

∴ DE is parallel to AC

→ From parallelism

∵ DE // AC

∴ m∠EDB = m∠CAD → corresponding angles

∵ m∠EDB = 83 - 7x

∵ m∠CAD = 7x + 55

→ Equate them

∴ 7x + 55 = 83 - 7x

→ Add 7x to both sides

∵ 7x + 7x + 55 = 83 - 7x + 7x

∴ 14x + 55 = 83

→ Subtract 55 from both sides

∵ 14x + 55 - 55 = 83 - 55

∴ 14x = 28

→ Divide both sides by 14

∴ x = 2

→ To find m∠CAD, substitute x by 2 in its measure

∵ m∠CAD = 7(2) + 55

∴ m∠CAD = 14 + 55

∴ m∠CAD = 69°

∴ The measure of ∠CAD is 69°

Consider the polar curve r = 4sin(2θ). What is the length of each petal, and how many petals does the graph have?

a.The length of each petal is 2, and the number of petals is 2.

b.The length of each petal is 2, and the number of petals is 4.

c.The length of each petal is 4, and the number of petals is 2.

d.The length of each petal is 4, and the number of petals is 4.

Answers

Answer:

The length of each pearl is a given r= a cos(n 0) the answer is 4 and number of petals is 4 (I think )

Step-by-step explanation:

The length of the petal and number of petals of the rose curve is required.

The correct option is d.

The given curve is

[tex]r=4\sin(2\theta)[/tex]

The general equation of a rose curve is

[tex]r=a\sin(n\theta)[/tex]

where

a = Length of petal

n = Number of petals if [tex]n[/tex] is odd

and [tex]2n[/tex] if [tex]n[/tex] is even.

So, here

[tex]a=4[/tex]

[tex]n=2n=2\times 2=4[/tex]

So, length of each petal is 4 and the number of petals is 4.

cross multiply

62.5

Her original score was 62.5

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here, her new score as 75 then let his original score be x

then 75 = (1+20%) × x

           x= 75/1.2

in standard form?

I will mark brainliest!!

Answers

Answer:

15x-5y=1

Step-by-step explanation:

y=3x−15

The standard form of a linear equation is Ax+By=C.

Multiply both sides by 5.

5y=5(3x−15)

Simplify 5(3x−15).

5y=15x−1

Rewrite the equation with the sides flipped.

15x−1=5y

Move all terms containing variables to the left side of the equation.

15x−5y−1=0

Add 1 to both sides of the equation.

15x−5y=1

Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/3 inch= 1 foot. In the drawing, the bathroom measure 3 inches by 3 1/3 inches. Amy is purchasing squares tiles that measure 1/3 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for bathroom floor

Answers

Answer:

$2,430

Step-by-step explanation:

Scale of the drawing = ⅓ in. to 1 ft

Measurement of the bathroom on paper = 3 in. by 3⅓ in.

Actual measurement of the bathroom:

3*3 = 9 ft

3⅓ * 3 = 10 ft

Area of the bathroom = 9*10 = 90 ft²

Let's find how many square tiles would cover 90 ft².

The side length of 1 tile is said to be ⅓ ft.

Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².

Number of tiles that would cover 90 ft² would be:

90/⅑ = 90*9

= 810 tiles

If 1 tile cost $3.00, therefore 810 tiles would cost:

810 * 3 = $2,430.

Using a layaway plan, Bill bought a set of golf clubs for $1700. He has 6 months to pay off his balance after paying a down payment. The store does not charge a fee for their program. If Bill makes payments of $201 a month, how much did he need to use as a down payment in order to pay for the clubs

Answers

Answer:

$494

Step-by-step explanation:

Given that:

Cost of golf club = $1700

Number of months taken to balance payment after down payment = 6 months

Amount paid per month = $201

The down payment made :

Cost of golf clubs - (monthly payment * number of months)

$1700 - ($201 * 6)

$1700 - $1206

= $494

Hence, the downpayment made = $494
