QS = 34

Step-by-step explanation:

Question: 12

1. 5x - 3 = 21 - x

2. 6x = 24

3. x = 4

so; 5(4)-3 = 17 and 21-4=17

Which means 17+17 = QS

QS=34

The value of x is 3 given that ST = 8x + 11 and TU = 12x-1

The point that bisects a line divides the line into two equal parts

If T is the midpoint of SU, the following are true:

  • ST = TU
  • ST + TU = SU

Given the following

ST = 8x + 11

TU = 12x-1

Since ST = TU

8x+11 = 12x-1

8x - 12x = -1 - 11

-4x = -12

x = 12/4

x = 3

Hence the value of x is 3 given that ST = 8x + 11 and TU = 12x-1

A movie theater has a seating capacity of 333. The theater charges $5.00 for children, $7.00 for students,
pantera1 [17]

Answer:

182 children, 91 adults, 60 students

Step-by-step explanation:

The quantity of adults is x, then the quantity of children are 2x,  the quantity of students is 333-x-2x=333-3x. The charge from all adults is 12x, students gave 7*(333-3x), children gave 5*2x=10x, the sum of all money is 2422

12x+ 7(333-3x)+10x=2422

12x+2331-21x+10x=2422

2331+x=2422

x=91- the amount of adults

1) 91*2=182- the amount of children

333-91-182= 60- the amount of students

I need help, pls can somebody help on this, it due this Friday
rusak2 [61]

Answer:

To express percentages in decimal form, you start with the decimal on the right side of the percentage, then you bring the decimal two places to the left. So for example, for 5% it it 5.. when you bring the decimal two places to the left it becomes .05

We start with $371.93 then we multiply each percentage successively to this number

we work backwards

so we start with 5%

$371.93= .95 x X

X=$391.51

Then we take X and do the same process for 10%

$391.51= .90 x Y

Y = $435.01

again we take Y and do the same process for 25%

$435.01= .75 x Z

Z = $580.01

so the original price is $580.01

to find the total percent discount you take the total discounted price ($371.93) divided by the original price ($580.01) then you have 1 subtracted by the number. Finally, you multiply the number by 100 to change it to a percentage

so it's $371.93/$580.01 which = .64125

1 - 64125 = .35875 x 100= 35.88%

so your total percent discount is 35.88%

Hope this helps

so 5/10 +9/10    (Now you just add the numerators and keep the common denominator the same)

14/10 and if you want to simplify it, simply divide both the top and bottom by 2

answer = 7/5
