Answer:

Step-by-step explanation:

a) Price of 4 bowls of soup + 6 hamburgers = $30

4s + 6h = 30 ---------------------(I)

Price of 1 bowl of soup + 3 hamburgers = $ 12.75

s + 3h = 12.75 -------------------(II)

b) s = 12.75 - 3h

Substitute the value of s = 12.75 - 3h in equation (I)

4*(12.75 - 3h) + 6h = 30

4*12.75 - 4 *3h + 6h = 30

51.00 - 12h + 6h = 30

51 - 6h = 30 {Now subtract 51 from both sides}

51 - 6h - 51 = 30 - 51

-6h = -21 {Now, divide both sides by (-6)}

-6h/-6 = -21/-6

h = 3.50

Price of one hamburger = $3.50

Substitute the value of h in equation (II)

s + 3 *3.50 = 12.75

s + 10.50 = 12.75 {Subtract 10.50 from both sides}

s + 10.50 - 10.50 = 12.75 - 10.50

s = 2.25

Price of one soup = $ 2.25

c) Price of 1 soup and 1 hamburger = 2.25 + 3.50

Price of 1 soup and 1 hamburger = $ 5.75

11/2 cup of black beans provides 15% of potassium you need daily. You must get the remaining 2890 mg from other sources. How man

stepladder [879]

The 11/2 cup of black beans is extraneous info, you just need to know that it provides 15% of the potassium you need daily. With that info, you know that you need 85% more to fulfill your daily value. If we say x is the total amount of potassium needed, then we can set up the equation:
x * 0.85 = 2890
Then we can solve for x by dividing both sides by 0.85. The answer, then, is 2890/0.85 = 3400 mg.

On Martin's first stroke, his golf ball traveled 4 5 5 4 start fraction, 4, divided by, 5, end fraction of the distance to the

faltersainse [42]

Answer:

0.395 kilometers

Step-by-step explanation:

Please consider the complete question.

On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball went into the hole. Martin was standing 79 meters from the hole as he took his second stroke. How many kilometers from the hole was Martin when he started?

Let x represent the distance between hole and start point.

In 1st stroke ball traveled 4/5 of the distance, so 1/5 of the distance was remaining from 2nd stroke to hole. This means the 1/5 of whole distance between start point and hole is equal to 79 meters.

We can represent this information in an equation as:

$\frac{1}{5}x=79$

$\frac{1}{5}x\cdot 5=79\cdot 5$

$x=395$

Since our distance is in meters, so we will convert 395 meters into kilometers by dividing by 1000.

$395\text{ meters}=\frac{395}{1000}\text{ km}=0.395\text{ km}$

Therefore, Martin was 0.395 kilometers from the hole, when he started.
