Answer:
27.78585
Step-by-step explanation:
The commutative property states that you can invert the order of the terms of a sum:
So, if you start with
Applying the commutative property you'll get
Answer:
1. Yes; 2. Yes ; 3. No; 4. Yes
Step-by-step explanation:
The proportion will have to be read the same way. For example top Δ bottom to the lower Δ bottom (locate in the same place)
14/21 = 6 /9 Yes because the top Δ bottom to lower Δ bottom = top side to
lower same side
13.5/21 = 9/ 14 Yes because the same two sides to the same two sides in
the lower Δ
9/13.5 = 6 21 No because top Δ side to lower Δ same location but the
second one top Δ side to the lower bottom
14 /6 = 21/6 Yes because top Δ bottom to top side = lower Δ bottom to
lower side (in the same place)
Bottle 1 = $1.92 & 12 ounces
Bottle 2 = $2.40 & 16 ounces
Bottle 1
If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.
$1.92 ÷ 12 = $0.16 per ounce for bottle 1.
Bottle 2
If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.
$2.40 ÷ 16 = $0.15 per ounce for bottle 2.
Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.
Answer:
2x +5y = -15
Step-by-step explanation:
We need to find the slope
m = (y2-y1)/(x2-x1)
= (-7--1)/(10- -5)
= (-7+1)/(10+5)
-6/15
-2/5
The point slope form
Y+7=
-2/5 (x - 10).
Distribute
y + 7 = -2/5x + 4
Add 2/5 x to each side
2/5x +y +7 = 4
Subtract 7 from each side
2/5x +y = -3
Multiply each side by 5
5(2/5x +y) = -3*5
2x +5y = -15
This is standard form Ax + By = C where A is a positive integer
