Answer:
$6.75
Step-by-step explanation:
First you find 25% of $9----> 2.25 and then you subtract that from 9----> 9-2.25=<u>6.75</u>
Answer: 36.6
Step-by-step explanation: 2x+1+3x-4=180
add 2 & 3 to get 5x
subtract 1 from 1 & 180
so u would have 5x-4=179
+4 to 179
then 5x=183
divide by 5
x=36.6
hope it helps
Answer:
11. c
12. c
Step-by-step explanation:
11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.
Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.
Angle RTS + Angle STU + Angle UTQ = 180 degrees
60 + 45 + Angle UTQ = 180
Angle UTQ = 180 - 105
= 75 degrees
12. Using the corresponding angles theorem, x = 45 degrees and y = 35 degrees.
x + y
45 + 35
80
Answer:
36 feet
Step-by-step explanation:
12x6÷2=36
Area of a triangle formula: Base x height divided by half
THIS ONLY APPLIES TO RIGHT TRIANGLES!
Hope this helps! Cheers :D
You could just factor out the Trinomial and find the zeros of the equation,
x^2 - 2x -15 = (x - 5)(x + 3) = 0,
x - 5 = 0 and x + 3 = 0, so x = 5,-3 AKA answer choice C
