Answer:
w=
or w=7.1142857
Step-by-step explanation:
add 2.5 to both sides
divide 17.5 from both sides
and you get your answers
Answer:
n > -15
Step-by-step explanation:
15 + n
15 + -16 (at least)
n = -1
Step-by-step explanation:
10 feet = 1 inch
50 feet = 5 inches
Do the same thing for the length.
If you don't under stand.
50/10 = 5
1/10 = x/50
10x = 50
x = 50/10
x = 5 inches
Then you do the same with the lenght.
Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
In this case: x 1 = - 10, y 1 = - 2;
x 2 = - 4 , y 2 = - 2
