Answer:
T=6 if S is equal to 7 you can solve it with 6×7 or 7÷42
Step-by-step explanation:
because 6×7=42
Answer:
B. -8
Step-by-step explanation:
Answer:
yes (6,7) is a solution.
Step-by-step explanation:
(6,7) is an ordered pair, see it like (x,y). so
x=6
y=7
substitute the variable with the values.
x+y=13
6+7=13
13=13
this is a true statement.
R = 12/2 = 6 π = 3.14
Circumference of a circle: C = 2πr
2*3.14*6
6.28*6 = 37.68 or 37.69
The last options seems reasonable
Hope that helps!
Answer:
Step-by-step explanation:
Given the perimeter of a rectangle P = 80 inches
Let 'x' be the width of a rectangle.
i.e.
x = width
As the length of a rectangle is three times its width. Thus,
length = 3x
We know that perimeter is the sum of all the sides (width and length) of a rectangle. So,
The Perimeter of a rectangle = 2(width + length)
substituting P = 80, width = x, length = 3x
80 = 2(x + 3x)
80 = 2x + 6x
80 = 8x
divide both sides by 8
80/8 = 8x/8
10 = x
Thus, the value of x = 10
Therefore,
The width = x = 10 inches
The length = 3x = 3(10) = 30 inches
Thus,
