Answer:
The actual wide of the lawn is 24 meters
Step-by-step explanation:
we know that
The scale drawing is
using proportion
Find out how wide is the actual lawn if the lawn is 48 millimeters in the drawing
Let
x -----> the actual wide of the lawn
therefore
The actual wide of the lawn is 24 meters
Answer:
x=5
Step-by-step explanation:
Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did
8-6*5=-22
And them I said let me see if any multiples equal -18 so I went to for and did this
8-6*4=-16
That's when I guessed the answer if i looked at the sign correctly!
So you’ll have to isolate the y by dividing the other side of the equation by 3
3y=-x-3
y=-1/3x-1
-1 will be your y intercept and the slope will be -1/3
you’ll start your line by plotting (0,-1)
then from that point you’ll count down one, right 3
or up one, left 3
hope this helps (:
Answer:
x = 10
Step-by-step explanation:
If f(x) equals 3x-7 and also equals 23, then you can set 3x-7 equal to 23
3x - 7 = 23
3x = 30
x = 10
Answer:
Step-by-step explanation:
Since you have
+
5
y
in one equation and
−
5
y
in the other equation, you can add both equations to cancel out the y terms and solve for x.
−
6
x
+
5
x
=
−
x
5
y
−
5
y
=
0
1
+
10
=
11
therefore
−
x
=
11
multiplying both sides by -1:
x
=
−
11
plugging this back into the first equation:
−
6
(
−
11
)
+
5
y
=
1
66
+
5
y
=
1
subtracting 66 from both sides:
5
y
=
−
65
divide both sides by 5:
y
=
−
13
putting the x-values and y-values into one point gives:
(
−
11
,
−
13
)
as the solution
