Answer:
x = 71º
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
the amount of visits given by the problem is:
and we have that the equation that relates the number of visits with the total cost is:
where 
is the total cost for 
number of visits.
We plug into this equation the known value of visitors:
and we solve this expression:
the total cost for 10 visitors is 17.
Answer:
3 cans
Step-by-step explanation:
area 1=.9×.3=.27 m²
area2=1/2×0.5×0.5=0.25/2=0.125 m²
total area=0.27+0.125=0.395 m²
area of 6 signs=0.395×6=2.370 m²
total cans reqd.=2.37/1=2.37
so 3 cans are reqd.
Answer:
Step-by-step explanation:
x = 2
step 1 :
(2 • (5x + 2) • 2) - 48 = 0
step 2 :
4 • (5x + 2) - 48 = 0
Pulling out like terms :
20x - 40 = 20 • (x - 2)
step 4 :
20 • (x - 2) = 0
Equations which are never true :
Solve : 20 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
