Answer:
x = -1
Step-by-step explanation:
y + 2x = -1
Subtract 2x from both sides;
y = -2x - 1
y = 3x + 4
-2x - 1 = 3x + 4
Subtract 3x from both sides;
-5x - 1 = 4
Add 1 to both sides;
-5x = 5
Divide both sides by -5
x = -1
Two hundred forty two thousand, six hundred twenty eight.
Answer:
2 bags
Step-by-step explanation:
area of the yard= 35*55= 1925 ft²
1 bag covers 1240 ft²,
required number:
1925/1240= 1.55 ≈ 2 bags
so 2 bags needed to cover the area of the yard fully
Answer:
Answer is C
Step-by-step explanation:
1) solve for 3/5x-3 = 3/5
= 8/5 or 1.6
so solve for x in ABCD and see what matches.
A) 24/25 or 0.96
This does not match
B) 17/15 or 1.13
This does not match
C) 8/5 or 1.6
THIS MATCHES
D) 5/8 or 0.625
This does not match

Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
