Solve for k

bearhunter [10]

Answer:

When solving equations the goal is to get the variable by itself so

4.5+1.5k=18-3k (first step is to subtract 4.5 from each side)

1.5k=13.5-3k (4.5-4.5=0, 18-4.5=13.5) (Next is to add 3k to each side)

4.5k=13.5 (1.5k+3k=4.5k, -3k+3k=0) (Last you divide both sides by 4.5)

k=3 (4.5/4.5=1, 13.5/4.5=3)

k=3

Hope this helps ;)

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need… to make 75% syrup? and 5%

sashaice [31]

Answer: There is 3.75 lbs of sugar and 1.25 lbs of water.

Step-by-step explanation:

Let the pounds of sugar to make 75% syrup be x

Since we have given that

Amount of sugar syrup = 5 lb

According to question,

$\frac{x}{5}=\frac{75}{100}\\\\\frac{x}{5}=0.75\\\\x=0.75\times 5\\\\x=3.75\ lbs$

Hence, there is 3.75 lbs of sugar and amount of water is given by

$5-3.75\\\\=1.25\ lbs$

Hence, there is 3.75 lbs of sugar and 1.25 lbs of water.

John is selling tickets to an event. Attendees can either buy a general admission ticket or a VIP ticket. The general admission

timofeeve [1]

Answer:

The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12

Step-by-step explanation:

Let

x ----> the number of general admission tickets sold

y ----> the number of VIP tickets sold

we know that

$x+y=33$ ---> equation A

$70x+105y=2,730$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both lines

using a graphing tool

The solution is the point (21,12)

see the attached figure

therefore

The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12
