Answer:
the answer is 3.75
Step-by-step explanation:
because 3/5 equal to 4/x. x=3.75
Answer:
15 and 1
Step-by-step explanation:
x and y are two numbers.
Two equations:
x · y = 15
x + y = 16
Rearrange one of the equations (I'll rearrange the sum equation):
x + y = 16
x = 16 - y
Substitute that to the other equation and solve for y:
x · y = 15
(16 - y) · y = 15
16 - y · y = 15
16 - y² = 15
-y² = 15 - 16
-y² = -1
y² = 1
y = √1
y = 1
Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):
x · y = 15
x · 1 = 15
x = 15
Now verify:
15 · 1 = 15
15 + 1 = 16
This is correct
I = Prt, where P = $1,295; r = 7/100 = 0.07, t = 180/365
I = 1,295 x 0.07 x 180/365 = $44.70
Answer:
The length of the fence is 38 yards
These are the expressions
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, a rectangle.
The length of the fence is the perimeter of the garden which is the expression that Chole could use
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Given data
Length = 11 yards
Width = 8 yards
Perimeter = 2(11)+ 2(8)
Perimeter = 22+16
Perimeter = 38 yards
