Answer: x = 22
Step-by-step explanation:
We must isolate the x by itself.
We need to add 5 to both sides of the equation so it cancel out from the side with x.
So x = 22
Answer:
g(x) = f(x) + 2
Step-by-step explanation:
To move the two to the other side of the equation, you have to add the two to both sides of the equation. The 2 cancels out on the g(x) side, and a 2 is added to the f(x) side.
Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective
The first one is -4 and the second one is 6.
