Plug in the options
not 5( 2 x 5) + 6= 16
not 1 ( 2 x 1) + 6 = 8
not -1 (2 x -1) + 6= 4
so its 5 ( 2 x -5) + 6= -4

She can paint 14 statues.

To find this answer, we just need to divide the amount of paint left by the amount of paint per statue.

7/8 divided by 1/16 is 14. To divide fractions remember it is easier to multiply by the reciprocal.

Answer:

  • x +3x = 180
  • x = 45 . . . . . . . choice C
  • 3x = 135 . . . . . choice F

Step-by-step explanation:

Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.

  x + 3x = 180 . . . . . . . . . equation for finding the angle

  x = 180/4 = 45 . . . . . .  divide both sides by 4

  3x = 3(45) = 135

The first angle is 45°. The second angle is 135°.

At the movie theatre, child admission is S5.20 and adult admission is $8.30. On Tuesday, 156 tickets were sold for a total sales
Annette [7]

Answer:

So, 89 Adult tickets were sold.

Step-by-step explanation:

So, we first name our variables, say, a for number of adult tickets, and c for child tickets.

Then we write our system of equations, first the total $ sale:

5.2c + 8.3a = 1087.10

Then we write the 2nd equation, the total number of tickets:

c + a = 156

Now, we can solve the system:

We do have different methods, let's to by subsitution.

make some change to the 2nd equation, to make c the subject: c = 156 - a

Now we plug that into the 1st equation:

5.2(156 - a) + 8.3a = 1087.10

811.2 - 5.2a + 8.3a = 1087.10

811.2 + 3.1a = 1087.10

3.1a = 275.9

a = 89
