X/25 + 89 = 81
x/25 = 81 - 89
x/25 = - 8
x = -8 * 25
x = - 200
The first one is true
I also believe the 3rd one is true.....u just forgot to put the " / " .
Answer:
y - 2 = 3(x - 2)
Step-by-step explanation:
Hello!
Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.
(2,2) is one point on the line, and the slope is m = -3.
Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).
Answer:
Danalya napped 1 7/20 hours.
Step-by-step explanation:
Rewriting our equation with parts separated
=3+3/4−2−2/5
Solving the whole number parts
3−2=1
Solving the fraction parts
3/4−2/5=?
Find the LCD of 3/4 and 2/5 and rewrite to solve with the equivalent fractions.
LCD = 20
15/20−8/20= 7/20
Combining the whole and fraction parts
1+7/20= 1 7/20
Answer:
13.3650978628
Step-by-step explanation:
Angle A=180-(Angle B+C)=180-117=63
Here,
b=BC, p=AC & AB=12
Using the relation of cos,
cosx=b/h
cos27=BC/15
15cos27=BC
Using a calculator,
BC=13.3650978628
Answer:
x>-9
Step-by-step explanation:
The given inequality is :
-3x - 7 < 20
We need to find the solution of the inequality using graph.
-3x - 7 < 20
Add 7 to both sides
-3x-7+7 < 20+7
-3x <27
x>-9
Hence, the attatched graph shows the solution of the given inequality.
