0.05 because 5 is bigger than 4 plus 4 is negative
Answer:
The total cost = $1,099
It would take 100 days
Step-by-step explanation:
Let
x = number of days
Cost of BT&T Cellular = 899 + 2x
Cost of Revizon Electronics = 799 + 3x
Equate the cost of both cell phone services.
899 + 2x = 799 + 3x
899 - 799 = 3x - 2x
100 = x
x = number of days = 100 days
Cost of BT&T Cellular = 899 + 2x
= 899 + 2(100)
= 899 + 200
= $1,099
Cost of Revizon Electronics = 799 + 3x
= 799 + 3(100)
= 799 + 300
= $1,099
Answer:
x = 2√3 ≈ 3.464
Step-by-step explanation:
The side marked x is opposite the given 30° angle. The side marked 6 is adjacent to that angle. The trig function relating opposite and adjacent sides of a right triangle is ...
Tan = Opposite/Adjacent
Filling in values, we have ...
tan(30°) = x/6
Multiplying by 6 gives ...
x = 6tan(30°) = 6(√3/3)
x = 2√3 ≈ 3.464
Answer:
7over9 or -7over9
Step-by-step explanation:
81x power 2 - 8 = 41
(left side) (right side)
first we let the 8 from left side go to the right side,so it will be +8:
81x power 2 = 41+ 8
=49
so now we let the 81 from left side go to right side, so it will be ÷81:
x power 2= 49 over 81
and now we let the power 2 (square) go to the other side so it will become square root:
x = + - √49 over 81
at the end, you will get 2 answers which is 7 over 9 and - 7 over 9
Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
