A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 55 pounds each, and the small boxes

weigh 30 pounds each. There are 110 boxes in all. If the truck is carrying a total of 4800 pounds in boxes, how many of each type of box is it carrying?

Answer:

Number of small boxes is 50 and number of big boxes is 60

Step-by-step explanation:

let the number of small box represent x and the number of big box represent y

Hence total number of boxes = x + y = 110 ......................Eqn1

Total weight of boxes = 30x + 55y = 4800----------------Eqn2

Solving both equations simultaneously

From Eqn1, x = 110-y, substitute it into equation 2

Hence, 4800 = 30(110-y) + 55y

1500 = 25y

y = 60

X = 110 - 60 = 50

Number of small boxes is 50 and number of big boxes is 60

Answer:

Step-by-step explanation:

let the number of dimes=x

and number of quarters=y

x=2y

0.10 x+0.25 y=2.25

or 10x+25y=225

divide by 5

2x+5y=45

2 ×2y+5y=45

4y+5y=45

9y=45

y=45/9=5

x=2y=2×5=10

Hence dimes=10

quarters=5

3x - 4y = -15 ; 4x +3y =5
Kipish [7]
Using elimination method to find y
3x - 4y = -15  (multiply 4)
4x + 3y = 5    (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y  = 15
--------------------- - (substract)
         -25y = -75
               y = 3

Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1

Answer:

1) The correct option is C. (2) The correct option is D. (3) The correct option is B. (4) The correct option is D. (5) The correct option is D.

Step-by-step explanation:

The slope formula is

m=\frac{y_2-y_1}{x_2-x_1}

(1)

Two points are (-2,5) and (1,4).

m=\frac{4-5}{1-(-2)}=\frac{-1}{3}tex]Therefore option C is correct.(2)Use the above mentioned formula for each pair of coordinates.[tex]m=\frac{10-13}{17-12}=\frac{-3}{5}

m=\frac{10-15}{13-16}=\frac{-5}{-3}=\frac{5}{3}

m=\frac{10-7}{3-0}=\frac{3}{3}=1

m=\frac{18-13}{8-11}=\frac{5}{-3}=\frac{-5}{3}

Therefore option D is correct.

(3)

The pair of points (6, y) and (10, -1). The slope is \frac{1}{4}.

\frac{1}{4}=\frac{-1-y}{10-6}

\frac{1}{4}=\frac{-1-y}{4}

1=-1-y

y=-2

Therefore option B is correct.

(4)

For vertical line the x coordinates always remains the same. Therefore when we subtract the same number we get zero in the denominator, therefore the value of slope is undefined for a vertical line.

Therefore option D is correct.

(5)

Two points from the table are (2,110) and (3,165).

m=\frac{165-110}{3-2}=\frac{55}{1}

Therefore option D is correct.
