Answer:
The area of 1/2 cm wide frame = 48 - 35 = 13 cm²
Step-by-step explanation:
Length of rectangular picture frame = 6 cm
Width of rectangular picture frame = 8 cm
Area of rectangular picture frame = 6×8 cm² = 48 cm²
Length, excluding 1/2 cm wide frame of rectangular picture = (6–1/2-1/2) = 5 cm
Width, excluding 1/2 cm wide frame of rectangular picture = (8–1/2-1/2) = 7 cm
Area, excluding 1/2 cm wide frame of rectangular picture = 5×7 cm² = 35 cm²
Area of 1/2 cm wide frame = 48 - 35 = 13 cm²
Therefore, the area of 1/2 cm wide frame = 48 - 35 = 13 cm²
15 is 2 1/2 of a number 6.
We need to find that 15 is 2 1/2 of what number.
In math, 'of' is also considered one of the arithmeticoperations which means multiplication within the brackets.
Let the unknown number be y.
Now, 2 1/2 of y=15
⇒5/2 ×y=15
⇒y=6
Therefore, 15 is 2 1/2 of 6.

▪ Answer:
n = 6
▪ Step-by-step explanation:
n × 2 1/2 = 15

n × 5 = 30
n = 30 ÷ 5
n = 6
Answer:
(3,2)
Step-by-step explanation:
Use the midpoint formula.
Add the x's together and then divide that by 2. Then do the same thing for the y's.
10+(-4)=6; 6/2=3
-2+6=4; 4/2=2
So, m=(3,2)
