Step-by-step explanation:
7x + 2 = 4x + 0
both sides substracted by 2
7x = 4x -2
both sides substracted by 4x
7x-4x = -2
3x = -2
both sides divided by 3
3x/3 = -2/3
=> x = -⅔
Answer:
777.9 meters
Step-by-step explanation:
Notice that the angles of the right triangle are 40 and 50 degrees, with the 500 meter side adjacent to the 50 degree angle. Now, we can set up an equation: cos (50 degrees) = 500 / x. Use a calculator to find that the answer is 777.9.
Answer:
Arithmetic sequences have a constant difference between consecutive terms. On the other hand, geometric sequences have a constant raito. In an arithmetic sequence, the terms can be determined by adding or subtracting a number to the preceding term, while for geometric sequences, each term is determined by multiplying or dividing a number to the preceding term.
