Answer:
4
Step-by-step explanation:
a triangle has angles that add up to 180°
an equilateral triangle has equal angles
so each angle is 60° (because 180/3 is 60)
so 10x +20 = 60
10x = 40
x = 4
Answer:
C(p) = p*50 + 300
Step-by-step explanation:
Using the names:
Clm: cost of labor and materials
Crm: fixed cost on rent and equipment
p: number of phones
and Ct: total cost
the ecuation would be number of phones times the cost and material plus the fixed cost, something like this
p * Clm + Crm = Ct
on the example we have all the data except the rent and equipment cost (the fixed cost) so thats what we need to solve
producing 3 phones its
3 *¨50 + Crm = 450
Crm = 450 - 150 = 300
so replacing in the above formula the equation would be
C(p)=p * 50 + 300
Answer: 0.6666... (never ending digit)
Step-by-step explanation:
2/3 divide the numerator, '2' by the denominator '3'
Answer:
b. x>1
Step-by-step explanation:
2/3+x/3>1
Multiply the inequality by 3 to get rid of the fractions
3(2/3+x/3)>1*3
2 +x >3
Subtract 2 from each side
2+x-2 >3-2
x>1
