Answer:
143
Step-by-step explanation:
x-31=112
Add 31 to both sides,
x - 31 = 112
+31 +31
-31 and +31, cancel out so we're left with...
x = 143
(2·3.5 + 4·3.25 + 2·1.9 + 1·1.2)·(1 - 0.05) = $23.75
Answer:
6.67
Step-by-step explanation:
Because in the park there are 30 people OK
15 were walking
7 were playing
6 were running.
15 + 7 + 6=28
Meaning there are still 2 people left so that is 6.67 =% of the people.
Hope it helps have a great afternoon:)
Answer:
Step-by-step explanation:
We have been given the intersection coordinates:
(7,1,-6) and perpendicular to the line x=-1+t ,y=-2+t and z=-1+t
From the condition of perpendicularity we know:
Now, we have given x=-1+t , y=-2+t and z= -1+t
Now, substituting t in the given coordinates x,y and z we get:
And
To find the quotient you do 6/ (-1/2). You keep, change, flip when dealing with fractions.
