The average of Johnny's two test grades is a 92 what must he get on his 3rd test to raise his average to a 94?
jeka57 [31]

Answer:

Johnny needs to score 98 on third test to raise average to 94

Step-by-step explanation:

Given that average of two tests is 92.

The score of next test has to be found that means there will be a total of 3 tests.

The average will be:

Avg = \frac{test1+test2+test3}{3}

It is also given that he has to raise his average to 98

We have to use the average formula for finding the third value

So,

94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282  = 184+test3\\test3 = 282-184\\test3 = 98

Hence,

Johnny needs to score 98 on third test to raise average to 94

What is the solution set to the following system? x+y=5 x^2 + y^2 = 25​
almond37 [142]

Answer:

D (0, 5), (5, 0)

Step-by-step explanation:

Anything with -5 and 0 will not satisfy x+y=5. This eliminates the first three choices.

It is easiest to check the offered answers. You can also solve this graphically, or by solving the simultaneous equations.

You can, for example, square the first equation and subtract the second:

... (x+y)² -(x²+y²) = 5² -25

... 2xy = 0

This will be true for x=0 or for y=0, so (0, 5) and (5, 0) are solutions to the pair of equations.
