5x + 14 = 28
5x + 14 - 14 = 28 -14
5x = 14
5x/5 = 14/5
x = 2.8
Answer:
b.) area of triangle= 1/2 base x height
A to B(base)= 8
height= 8
8 × 8= 64
64÷ 2= 32
area of the triangle= 32
I think this is correct aha
2/3 of its capacity - 60 * 2/3 gallons = 40 gallons.
Time to fill to 2/3 is 40 / 4/5 = 40 * 5 / 4
= 50 seconds (answer)
If you apply a linear transformation
to a random variable X, the mean and standard deviations change as follows:
So, the new mean is
and the new standard deviation is
The value is -4.
7x=42
/7 /7 (Divide both sides by 7)
x=6
If we insert x=6 into 44-8x, it is 44-8(6), which is 44-48.
44-48=-4, so the answer is -4.
