A theater has 675 seats. there are three times as many seats in a row as their are rows

Answers

Answer:

Step-by-step explanation:

let the number of rows=x

seats in each row=3x

so number of seats=x(3x)=3x²

3x²=675

x²=225

x=15

number of rows=15

and seats in each row=15×3=45

Answer: 15 rows with 45 seats each

Step-by-step explanation:

Let x = the number of rows, then 3x= the number of seats in a row.

seats × row= total

3x × x=675

3x²=675

x²=225

x=15

If I get played 9$ an hour and I work 8:15 a day how much do I get for 5 days

Answers

First of all, 15 minutes is 1/4 of an hour. So 8:15 is 8.25 hours.

(8.25 hours/day) x ( 9 $/hour) x (5 days) = $371.25

so first you multiply 9*8=72
and then you find how much is 15 min of an hour which is 1/4
and 1/4 of a dollar is 25 cents so you would get payed $72.25

In your own words, explain the
term midpoint.

Answers

Ok in my own words hmm.

Midpoint to me would be the point in the middle.

I've seen and worked with midpoints on lines and triangles.

So the midpoint would be the point in the middle of a line segment.

Find the missing coordinate to complete the ordered-pair solution to the given linear equation:

A) y+6x=5

(a) (-1,?)

(b) (3,?)

B) 3x+2y=-6
(a) (-2,?)

(b) (?,3)

C) 2x+1/3y=5
(a) (?,18)

(b) (8/3,?)

Answers

A
a) y+6x=5 if x= -1 then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5 subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13

B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4
