Take away the bottom equation from the top so the y’s cancel out
3x = -24
x therefore = -8
and put x back into the equation to find out y
2(-8) + y= 32
-16 + y =32
y= 48

mojhsa [17]

Answer: 4/8

Step-by-step explanation:

From the question, Mrs Andrews had 1 2/8 pizzas left after her party and after giving some to Mr Andrews, she then had 6/8 left.

To know the fraction given to Mr Andrews, we subtract 6/8 from 1 2/8. This will be:

The instructor had saved $3,500 and rents an apartment
Juli2301 [7.4K]

Step-by-step explanation:

The instructor had saved $3,500 and rents an apartment  for $275 monthly. The slope-intercept form of the above scenario is :

y=-275x+3500

The instructor belives that the point (6, 1850) would  be on the equation of the line. Put y = 1850 and x = 6 in the above equation. So,

1850=-275(6)+3500

1850=1850

LHS=RHS

It means that the point (6,1850) lies on the line. Hence, he was correct.

Step-by-step explanation:

Mean and median terms are use to measure the central tendency in a data set.

Mean is the best measure of center if there is no outlier present in the data otherwise median is the best measure of center if there is outlier present because outliers effects the means value of a data but not the median value.

In the third period, there is an outlier present as 8 that affects the center, then the best measure of center for third period must be Median.
