Two families went to a baseball game. The first family bought 5 pretzels and 4 sodas, which totaled $30. The second family bough

Alinara [238K]

The cost of one soda bought by both families is $5.

<h3>What is the total cost of shopping for each family?</h3>

The cost of purchase is the sum of number of items bought and their prices for each family.

Let us assume that x is for number of pretzels bought and y is for number of sodas bought, as a result, the total amount spent by each family and number of items bought are expressed thus:

5x+4y=30.....................(equation 1)

4x+5x=33 .....................(equation 2)

let us multiply equation 1 by 5

let us multiply equation 2 by 4

5*(5x+4y=30)25x+20x=150........(equation 3)

4*(4x+5x=33)16x+20x=132..........(equation 4)

equation 3 minus equation 4 is:

9x=18

x=18/9

x=2

price of pretzels is $2.00

Substitute for x in equation:

24x+5y=33(4*2)+5y=33

8+5y=33

5y=33-8

5y=25

y=25/5

y=5

price of one soda=$5

Answer:

159

Step-by-step explanation:

Based on process of elimination, it cant be 51 nor 55 because that angle is 100% bigger than 90 degrees. To find it correctly, all you would do is add them. 105 + 54= 159

1. Point V is somewhere on the line segment UW. If UV = 8 then find the length of VW.

alekssr [168]

Answer:

VW = 3

Step-by-step explanation:

From the diagram, we know that UW = 11.

We also know that UV + VW = UW, because UW is the length of the whole segment.

Using substitution (knowing 2 of the line segments), we find that 8 + VW = 11.

If we subtract 8 from both sides using inverse operations, we find that VW = 3, which is the answer.

Hope this helps!
