Answer:
Perimeter = 64m
Step-by-step explanation:
I can only help for Perimeter.
12+20+12+8+8+4=64m
Answer:
The width of the rectangle=21 inches
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the rectangle</em>
Width=w
Length=l
But;
triple width=length+36
3×w=l+36
3 w=l+36
The length can be expressed as;
l=3 w-36
width=w
length=3 w-36
<em>Step 2: Determine the perimeter of the rectangle</em>
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=96 inches
W=w
L=3 w-36
replacing;
2(w+3 w-36)=96
2(4 w-36)=96
8 w-72=96
8 w=96+72=168
8 w=168
w=168/8=21
The width of the rectangle=21 inches
Answer: The coefficient would be 10x
Explanation: the coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).
Answer:
38/50 or 19/25
Step-by-step explanation:
One way could be that you add all the marbles together to get your total marbles; 12 + 10 + 15 + 13 = 50.
Then you add all the colours expect red; 10 + 15 + 13 = 38.
Which would give me 38/50; which simplifed would be 19/25
