Mariah spent $9.50 on 9 pounds of limes and pears. Limes cost $0.50 per pound and pears cost $1.50 per pound. Let l be the numbe

r of pounds of limes and let p be the number of pounds of pears.
The system of linear equations that models this scenario is:

l + p = 9

0.5l + 1.5p = 9.5

How many pounds of each type of fruit did she buy?

Answer:

4 pounds of lime and 5 pounds of pears

Step-by-step explanation:

I + P = 9

0.5l + 1.5P = 9.5

I = 9 - P

0.5(9 - P) + 1.5P = 9.5

4.5-0.5P + 1.5P = 9.5

4.5 + P (1P) = 9.5

P = 9.5-4.5 = 5

I = 9 - 5 = 4

Answer: 4 pounds of lime and 5 pounds of pears

What are the values for the coefficients and constant term of 0 = 2 + 3x2 – 5x?
tangare [24]

Keywords:

<em>Polynomial, variable, coefficients, constant term. </em>

For this case, the first thing we must do is rewrite the polynomial in a standard way. For this, we reorder the polynomial coefficients.

The standard form of the polynomial is:

ax ^ 2 + bx + c

Where,

a, b, c: are the coefficients of the polynomial.

x: is the variable

Rewriting the polynomial we have:

3x ^ 2-5x + 2

Comparing with the standard form we have that the values of the coefficients are given by:

a = 3\\b = -5\\c = 2

Answer:

The values for the coefficients and constant term are:

a = 3\\b = -5\\c = 2

Bill sees two boxes of baseball cards at a card show. The first box has 150 cards for $12.55.The second box has 120 cards for $9
Grace [21]

Answer: Cards in second box are cheaper.

Step-by-step explanation:

We are told that the first box has 150 cards for $12.55. Therefore, the cost of one card would be:

= $12.55 / 150

= $0.084.

The second box has 120 cards for $9.60. Therefore, the cost if one card would be:

= $9.60 / 120

= $0.08

Therefore, the cards in the second box are cheaper.
