Answer:
All real values, (-∞, ∞)
Step-by-step explanation:
<u>Step 1: Distribute</u>
5y + (86 - y) = 86 + 4y
5y + 86 - y = 86 + 4y
<u>Step 2: Combine like terms</u>
5y + 86 - y = 86 + 4y
4y + 86 = 86 + 4y
<u>Step 3: Subtract 4y from both sides</u>
4y + 86 - 4y = 86 + 4y - 4y
86 = 86
<u>Step 4: Subtract 86 from both sides</u>
0 = 0
Answer: All real values, (-∞, ∞)
I think it’s a and c might be wrong though
Answer:
Perimeter = 28 mt or 2800 cms
Step-by-step explanation:
Formula for Perimeter is
P = 2(l+b)
Here P = we have to find
Length = l = 1200 cm Given
Width = b = 2 m = 200 cm (Given and converted into cm as the units must be same)
Putting those values in the formula
P=2(1200+200)
P=2(1400)
P=2800 cm
P=28 mt
Answer:
14.35 grams
Step-by-step explanation:
Amount left, in grams = (970 grams)(1.000 - 0.277)^m, where m is the number of minutes. This is exponential decay.
Amout left = (970 grams)(0.723)^13 = (970 grams)(0.01475), or 14.35 grams
