Price: $8.62 per 3 lb of strawberry
How much will it cost to buy 4.2 lb of strawberries? (Round to 2 decimal digits if necessary)

Answers

9514 1404 393

Answer:

  $12.07

Step-by-step explanation:

The cost is proportional to the weight, so we have ...

  dollars/pounds = c/4.2 = 8.62/3

Multiplying by 4.2 gives ...

  c = 4.2×8.62/3 = 12.068

The cost of 4.2 pounds of strawberries is $12.07.

Carlos has 2 dollars more than half of the total amount of money his brother has. If x represents the amount of money Carlos's brother has, which expression can be used to represent this situation?

Answers

Answer:

[tex]y = 2 + \frac{1}{2}x[/tex]

Step-by-step explanation:

Given

Represent Carlos with y and his brother with x.

Analysing the statement one after the other:

Half of his brother's amount is: [tex]\frac{1}{2}x[/tex]

$2 more: means we add 2 to [tex]\frac{1}{2}x[/tex]

So, we have: [tex]2 + \frac{1}{2}x[/tex]

The above represent Carlos's amount.

So, the expression is:

[tex]y = 2 + \frac{1}{2}x[/tex]

To obtain a term in the sequence add d = 3 to the previous term, then

Answer:

X= 2

y = 2

Step-by-step explanation:

y=-2x+6............... equation 1

y=3x-4................... equation 2

from equation 2

y=3x-4

substitute y=3x-4 in equation 1

3x-4=-2x+6

collect like terms

3x+2x=6+4

5x=10

divide both sides by 5

X=2

substitute X=2 in equation 1

y=-2x+6

y=-2(2)+6

y=-4+6

y=2

Three angles are in the ratio 2:3:5
The smallest angle is 50
Work out the sizes of the other two angles

Answers

Answer:

The other two angles are 75° and 125°.

Step-by-step explanation:

Let three angles are 2x, 3x and 5x.

The smallest angle is 50.

It means,

2x = 50

x = 25

So,

3x = 3(25) = 75°

5x = 5(25) = 125°

So, the other two angles are 75° and 125°.

The amount paid for different weights of oranges at a farmer’s market are shown below.

Answers

The answer is 8lbs because 3/2 is 1.5 and 12/1.5 is 8

Answer:

8

Step-by-step explanation:

Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.

So:

$3.00 / 2 = $1.50

So now we have :

1 pound of oranges = $1.50

With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).

Like so:

$12.00 / $1.50

=

8

We can check this by inputting the 8 on the ?

If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.

Hope this helps!
