Answer:
Statement 4 is incorrect.
Step-by-step explanation:
#4 is incorrect. This statement is assuming that both 3x+5 and 4x are equal, but the correct way to use them and achieve 180 (definition of supplementary) degrees is by writing it as: 3x+5 + 4x = 180. (I spaced the 3x+5 and 4x to make it clear that these are two angles added together.) With this equation, you will be able to find the x and the substitute it back in to complete the equation.
If the line is perpendicular to x = 4, then that means the answer should be y = some number
and since we have the equation going through point (5,7), we look at the y-value since our equation is y=some number and replace the y-value into that equation.
So the correct answer is C. y = 7

Mark could travel 682.5 miles in 7.5 hours.
To solve this you have to find how fast he travels per hour.
455 miles/5 hours=91 mph
91 mph multiplied by 7.5 hours(91 x 7.5)= 682.5
682.5 Miles in 7.5 hours
Hope this helped you! :D
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32
Step-by-step explanation:
BAC=20°
BCA=90°
BC=3(P)
AB=?(H)
NOW,

Sin 20°=<u>3</u><u> </u><u> </u><u> </u>
AB
0.342=<u>3</u><u> </u><u> </u><u> </u>
AB
AB=<u>3</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
