Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14
Step-by-step explanation:
Answer:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x
and solve for
y.x-intercept(s): (3,0)
y-intercept(s): (0,−3)
Step-by-step explanation:
Answer:
2*2*2*2*2*2*2*2*2=512
2*2*2*2*2=32
512/32=16
Step-by-step explanation:
You got both questions correct :)
Using a system of equations, it is found that 1530 more novels have been bought in total.
For the system, we have that:
- x is the number of novels.
- y is the number of dictionaries.
The ratio of the number of novels to that of dictionaries is 2:3, hence:
Total number of novels is 624, hence:
Buys z more novels, and the ratio becomes 
, hence:
1530 more novels have been bought in total.
