Answer:
x = 6
Step-by-step explanation:
44 + 3x = 5x + 2x + 20 transfer like terms to the same side of the equation with the opposite sign:
44 - 20 = 5x + 2x - 3x add/subtract like terms
24 = 4x divide both side by 4
6 = x
Answer:
405.
Step-by-step explanation:
This is a geometric sequence where the nth term = a1 r^(n -1).
Here a1 = 5 and r = 3 so
the fifth term a5 = 5(3)^(5-1)
= 5 * 81
= 405.
Remark
I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.
Step One: Set up the equation. The normal way of solving this would be to use the Cos function.
Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8
8*cos(theta) = x Theta = 35
8*cos(35) = x This is about as simple a way as is possible.
6.553 = the height of the sale.
Step Three: try using the reciprocal
1 / cos(35)= hypotenuse / adjacent
1/0.8191 = 8/x cross multiply
x = 0.8191 * 8
x = 6.553
Answer:
22.2m
Step-by-step explanation:
1 roll to 12 gifts
one gifts uses 1,85m of ribbon
1,85m is the length
12 × 1.85 = 22.2m
