Answer:
725
Step-by-step explanation:
30 - 1 = 29
29 x (25/1) = 725
Answer:
OPTION A: Divide both the sides by 5
Step-by-step explanation:
We are given: 5z - 3 = 12
When we add 9 to both sides we get:
5z - 3 + 9 = 12 + 9
⇒ 5z + 6 = 21
⇒ 5z = 21 - 6 = 15
⇒ 5z = 15
To find the value of z we have to divide both the sides by 5.
i.e., 
⇒ z = 3.
Answer:
2870

Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
You would have to find the slope of the equation first.
4x+3y=-8
-4x -4x
3y=-4x-8
_ ____
3 3
y=-4/3x-8
For a line to be perpendicular to another line, the slope,m, of the new equation would need to be the negative reciprocal of the original. To put it short, take the fraction, flip it, and multiply it by -1.
original m=-4/3
perpendicular m= 3/4
You would use the slope-intercept form to solve for the new equation.
y1=y value
x1= x value
y-y1=m(x-x1)
y-(-15)=3/4(x-12)
distribute:
y+15=3/4x-9
then solve for y:
y+15=3/4x-9
-15 -15
y=3/4x-24
