Answer:
C. -12
Step-by-step explanation:
divide each side by 2/3
2/3x ÷ 2/3 = x
-8 ÷ 2/3 = -12
x = -12
Answer: none of them is right, did you meant maximum 4 and minimum 2?
Step-by-step explanation: cos x gets values between 1 and -1.
If you add 3 you get values between 4 and 2.
Answer:
the larger number is 50
Step-by-step explanation:
Notice there are two unknown numbers. Let's address the smaller one as x and the larger one as y. now we can write two equations from translating the phrases given into algebraic expressions:
"the sum of two numbers is 80" can be written as:

Now the second phrase:
"The ratio of those two numbers is 3/5"
Notice here that in our ratio we need to use our small number (x) in the numerator of the quotient, and the larger number (y) in the denominator to make it in agreement with the small and larger numbers of the ratio
, and solve for x:

Replace the value of x we just obtained in the first equation we wrote, so we obtain one equation with only one unknown hat we should be able to solve:

Therefore the larger number (y) equals 50.
Answer:
1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.
64 × 64 = 256 units.
2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.
which is 256 : 4 = 16 units.
Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.
