Answer:
3n = 2n + 4
Step-by-step explanation:
That is that as an equation.
Answer:
Dimensions : 37.5 * 12.5
length : 37.5
width : 12.5
Step-by-step explanation:
let x = length and y = width
x = 3y based on info from problem
Perimeter = 2(length + width)
100 = 2(x + y)
substitute 3y for x
100 = 2(3y + y)
100 = 2(4y)
100 = 8y
y = 12.5
x = 3(12.5) = 37.5
680x+10y=1000. Ax+By=C not sure if that’s what your teacher is looking for
12/3 = x/8
Cross multiply
3x = 96
Eliminate
3x/3 = 96/3
x = 32
... of points
hope helped and that is understandably sure
