Get rid of cos2x by dividing both the values. So Sin2x/cos2x +3cos2x/cos2x.
Tan2x = 3
2x = -71.5 so x is -35.6
Use the quadrant method and add 360 twho the two values tou get.
18) Seven less than the product of a number z and 3 is equal to 4
Product of a number z and 3 ⇒ 3z
Seven less than^ ⇒ 3z - 7
Equal to 4 ⇒ = 4
3z - 7 = 4

19) Make an equation for this problem. Your equation will look like:
d + 132 = 468, where d + 132 is the distance she drove on Monday and 468 is the distance she drove on Tuesday.
Solve the equation for d by subtracting 132 from both sides.
d = 336
The truck driver drove 336 miles on Monday, so that means she did not drive 600 miles on Monday.
Answer:
18
Step-by-step explanation:
12/14 = 6/7
6/7 = 12/14 = 18/21
I'm assuming that you are trying to solve the equation for y, which we can do by isolating the variable on one side of the equation.
y/7 = 4
To get rid of the denominator of y, we have to multiply both sides by this amount (7).
(y/7)*(7) = (4)(7)
When we simplify, we get:
y = 28
If we go back to the original equation and plug in our answer, 28/7 = 4, we can see that it results in a true statement.
Therefore, the answer is y=28.
