Mathematics
1 answer:
Savatey [412]3 years ago
7 0

Answer:

x = 5

AB = 26

BC = 39

Step-by-step explanation:

A___B___C

AC = AB + BC

65 = (5x+1) + ( 7x+4 )

65 = 12x + 5

12x = 65-5

12x = 60

x = 60/12

x = 5

AB = 5x +1 = 5(5) +1 = 25 +1 = 26

BC = 7x+4=7(5) + 4 = 35 +4 = 39

I hope I helped you^_^

Tickets for a carnival cost $8 for children 12 and under and $12 for anyone over the age of 12. The carnival sold 233 tickets an
jenyasd209 [6]

Answer:

They sold 160 children's tickets.

Step-by-step explanation:

With the information provided, yoou can write the following equations:

x+y=233 (1)

8x+12y=2,156 (2), where:

x is the number of tickets for children 12 and under

y is the number of tickets for anyone over the age of 12

Now, you can solve for x in (1):

x=233-y (3)

Then, you have to replace (3) in (2) and solve for y:

8(233-y)+12y=2,156

1,864-8y+12y=2,156

4y=2,156-1,864

4y=292

y=292/4

y=73

Finally, you can replace the value of y in (3) to find x:

x=233-73

x=160

According to this, the answer is that they sold 160 children's tickets.

ASAP need help with system of equations... I'm too small brain to do it.
navik [9.2K]

Answer:

(x=0, y=11)

(x=2, y=9)

Step-by-step explanation:

first equation substitution for x first.

y=11-x

plug into 2nd equation

(x+2)^2+(11-x-7)^2=20

this should lead you into a quadratics equation.

you get x=0, x=2.

do the same for y value this time, subbing in the x value

(11-y+2)^2+(y-7)^2=20

this also leads into a quad equation

solve and you get y=11, and y=9

You work as a cashier for a bookstore and earn $4 per hour. You also babysit and earn $8
Anna71 [15]

Answer:

The correct option is C

Step-by-step explanation:

Lets find the linear equations:

For Hours

Let

Number of hours in bookstore per week = x

Number of hours for babysitting per week = y

Total number of hours ≤ 16

So the first equation us:

x + y ≤ 16

y ≤ 16 - x

For Money

Let

Amount earned per hour from bookstore = $4

Total Amount earned from bookstore = 4x

Amount earned per hour from babysitting = $8

Total Amount earned from babysitting = 8y

Total Amount earned ≥ $56

So the second equation is:

4x + 8y ≥ 56

8y ≥ -4x + 56

y ≥ -(1/2)x + 7
