8 – 6 (x – 4) = 2x – 2 (4x – 5) + 22

Answers

Answer:

Here

Step-by-step explanation:

Let's solve your equation step-by-step.

8−6(x−4)=2x−2(4x−5)+22

Step 1: Simplify both sides of the equation.

8−6(x−4)=2x−2(4x−5)+22

8+(−6)(x)+(−6)(−4)=2x+(−2)(4x)+(−2)(−5)+22(Distribute)

8+−6x+24=2x+−8x+10+22

(−6x)+(8+24)=(2x+−8x)+(10+22)(Combine Like Terms)

−6x+32=−6x+32

−6x+32=−6x+32

Step 2: Add 6x to both sides.

−6x+32+6x=−6x+32+6x

32=32

Step 3: Subtract 32 from both sides.

32−32=32−32

Assume that Q, R, and S are the angles of a triangle, with opposite sides q, r, and s respectively. Select all of the following that represent the law of cosines. q2 = r2 + s2 – 2rscos(Q) . q2 = r2 + s2 – 2qscos(R) . r2 = q2 + s2 – 2qscos(Q) . r2 = q2 + s2 – 2qscos(R) .s2 = q2 + r2 – 2qrcos(S)

Answers

Answer:

A. q2 = r2 + s2 – 2rscos(Q)

D. r2 = q2 + s2 – 2qscos(R)

E. s2 = q2 + r2 – 2qrcos(S)

Step-by-step explanation:

The following relation represent the law of cosines.

                  [tex]q^{2}=r^{2}+s^{2} -2rscos(Q) \\\\r^{2}=q^{2}+s^{2} -2qscos(R) \\\\s^{2}=r^{2}+q^{2} -2rqcos(S)[/tex]

Law of cosines:

The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.

It is given that, Q, R, and S are the angles of a triangle, with opposite sides q, r, and s respectively.

A bacon cheeseburger at a popular fast food restaurant contains 2,070mg of sodium, which is 86% of the recommended daily amount. What is the total recommended daily amount of sodium?

Answers

So to find out what number 2070 is 86% of you do:
x(86/100)=2070
and solve for x.
after you solve you will get; 2407 mg
so the recommended daily amount is 2407 my

Answer:

2,407mg of sodium is the recommended daily amount

Step-by-step explanation:

Using the cross multiplication you will get the answer.

1. make the problem as a fraction   [tex]\frac{2070}{x} =\frac{86}{100}[/tex]  

2. Cross multiply (2070*100=86*x)

3. Simplify the equation left. 207000 = 86x

                                                 2407 ≈ x   (Divide both sides by 86)

Answers

9514 1404 393

Answer:

  a) $166.67

  b) $150

  c) 38.04%

Step-by-step explanation:

a) The selling price (s) is the sum of the wholesale price (w) and the markup (m).

  s = w + m

We have ...

  250 = w + 0.50×w

  250/1.50 = w = 166 2/3 ≈ 166.67

The wholesale cost of the bike is $166.67.

__

b) The price of the bike after the discount is 100% -40% = 60% of the tagged price:

  0.60 × $250 = $150 . . . . . the discounted price

(Aside: we note this is less than the wholesale price, so the store is taking a loss on the bike when it is discounted this much.)

__

c) The percentage change is found by ...

  percent change = ((new value)/(old value) -1) × 100%

  = (114/184 -1) × 100% = (0.619565 -1) × 100% ≈ -38.04%

The discount is about 38.04%.
