You will want to solve for x.
-1>-2(x-4)-5(4x-7)           Multiply
-1>-2x+8-20x+35            Add like terms
-1>-22x+43                     Subtract 43 from both sides
-44>-22x                         Divide -22 (since negative, flip inequality sign)
2<x                                 The answer

So x>2

I hope this helps... Have a great day!

The equation that can be used to represent total tickets sales is 2170 = 5s + 2f + 10a

<h3>Equation</h3>

let

  • Number of students tickets = s
  • Number of faculty tickets = f
  • Number of alumni tickets = a

Expression for number of students tickets sold;

s = f + 15

Expression for number of faculty tickets sold;

f = 2a

Expression for number of alumni tickets sold;

f = 2a

a = f/2

  • Cost of students tickets = $5
  • Cost of faculty tickets = $2
  • Cost of Alumni tickets= $10
  • Total revenue = $2170

2170 = 5s + 2f + 10a

An angle measures 67.2° less than the measure of a supplementary angle. What is the measure of each angle?
arlik [135]
Two supplementary angles always adds up to 180 degrees. If an angle is 67.2 degrees less than the measure of a supplementary angle, an equation can be formed where "A" represents the larger angle, and (A - 67.2) represents the smaller angle.

(A - 67.2)+A=180

(Combine the A's)

2A - 67.2=180

(Add 67.2 to both sides)

2A = 247.2

(Divide by 2 to both sides)

A = 123.6

123.6 degrees is the larger angle.

The smaller angle is represented by (A - 67.2). We now know the value of A so lets plug it in. (123.6 - 67.2) = 56.4. 56.4 is the value of the smaller angle.

We can double check to make sure we got the right answer.

123.6 + 56.4 = 180

Early detection of cancer __________.
nadezda [96]
<span>Early detection of cancer increases the likelihood of living, increases the chance for a cure and makes it less likely that the cancer has metasasized. the time spent in hospital depends more on the the type of cancer and what treatment is appropriate. Early detection means finding the cancer whil it is still relatively simple, before large tumours and secondary tumours have developed.</span>
