Answer:
l = 14
Step-by-step explanation:
Given
p = 2l + 2w and w = 7, p = 42, substitute values into formula
42 = 2l + (2 × 7), that is
42 = 2l + 14 ( subtract 14 from both sides )
28 = 2l ( divide both sides by 2 )
14 = l or l = 14
Answer:
Step-by-step explanation:
The equation of a line in point- slope form is
y = mx + c ( m is the slope ( gradient ), c is the y- intercept )
y = x ← is in point- slope firm
with gradient =
add 0+1+2+3+4 = 10
divide 10÷5 = 2
add 15+8+3+3+1 = 30
divide 30÷5 = 6
the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.
