Where is the Question? or am i just blind
Answer:
<em>The number is -6.</em>
Step-by-step explanation:
Let x = the unknown number
"the sum of a number and four" = n + 4
"Six times the sum of a number and four" = 6(n + 4)
"Six times the sum of a number and four is -12." is the equation
6(n + 4) = -12
Divide both sides by 6.
n + 4 = -2
Subtract 4 from both sides.
n = -6

Answer:
y = 48
Step-by-step explanation:
given y is directly proportional to x then the equation connecting them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 36 when x = 30
k = 
= 
= 
y = x ← equation of proportionality
When x = 40 then
y = × 40 = 48
