Answer: x=5 z=115
Step-by-step explanation:
First, subtract 91 from 180(which is the amount of degrees on the line)
Secondly, subtract 24 from 89(which is the amount of degrees on the x portion
Next, divide 65 (the amount of angles missing after subtracting 24)
Lastly, add 65(for the perpendicular value), then find the difference between 180 and 65 to get to the value of z.
Answer: -25
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
You set f(x) = 9 and solve from there.
9 = 4x - 7
+7 +7
16 = 4x
/4 /4
x = 4
Answer:
3x + 3y = x+ 7y is the equation and solutions are in bold below
subtract 3y from both sides
3x= x + 4y
subtract x from both sides
2x=4y
divide both sides by 2
x = 2y
Now we solve for y
3x + 3y = x+ 7y
2x=4y
0.5x = y
y = 0.5x or 1/2x
Step-by-step explanation:
Answer:
1) 9.69
2) 87.36
3) 171.42
4) 18.75
5) 16.29
Step-by-step explanation:
Treat each value's full price as x. then, all of the values are (2/3)x. To get (2/3)x back to x, we must multiply (2/3)x*(3/2)=x. Multiply each of the questions given by 3/2 or 1.5
