Answer:
x=5
Step-by-step explanation:
x+5 = -3x+25
Add 3x to each side
x+3x+5 = -3x+3x+25
4x +5 = 25
Subtract 5 from each side
4x+5-5 = 25-5
4x = 20
Divide each side by 4
4x/4 = 20/4
x =5
Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.
y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b
so ur perpendicular equation is : y = -2x + 1
Answer:
6 pieces of rope
Step-by-step explanation:
if the total is 54 and each are 9 you can make an equation
54= 9 x a
solve for a
to do this you divide 54 by 9
54/9=6
Answer:
Avoid Using too many statistics
Step-by-step explanation:
when a speaker is giving a speech, the listeners prefer main points to hearing too much of statistics. Too many statistics bore the audience and sometimes divert their attentions from the crux of the speech. If statistics are to be given, they must be clearly expressed and the source should be clearly stated.
Numbers that are of large decimal points can be rounded off so as not to confuse the audience and to make them grasp the main idea.
