Answer:
18.5 in=decimal feet,
Step-by-step explanation:
1)18.5/12=18.512
2)18.512=1.542 feet
y < –12
Solution:
Step 1: Given inequality is y + 15 < 3.
To find the solution to the inequality.
Step 2: Subtract –15 on both sides to equal the expression.
⇒ y + 15 –15 < 3 –15
Step 2: Using addition identity property, any number adding with zero gives the number itself.
⇒ y + 0 < –12
⇒ y < –12
Hence the solution to the inequality is y < –12.
Answer:
C. 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²
Step-by-step explanation:
Convert every measurement to the same unit, say, square metres.
(a) 3.8 m²
No conversion necessary
(b) 380 cm²
(c) 0.038 km²
(d) 3800 mm²
In decreasing order, 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²
Answer:
add x
Step-by-step explanation:
The operation "subtract 5" has eliminated the constant from the right side of the equation, so the next step would be to eliminate the variable from the left side. You do that by adding the opposite of the variable term.
The opposite of the term -x is x, so we "add x" as the next step.
This makes the solution look like ...
-x +6 = 5 -3x
-x +1 = -3x . . . . . . subtract 5
1 = -2x . . . . . . . . . add x
-1/2 = x . . . . . . . . .divide by -2

<em>Comment on this solution</em>
My preference is always to add the opposite of the variable term with the smallest coefficient. Here, that term is -3x, so I would add 3x as a first step. This leaves the only x-term with a <em>positive</em> coefficient, so can reduce errors in the solution.
