Answer:

(-1,3)

Step-by-step explanation:

2x-3y=9 multiply by 3 to get 6x-9y = 27

3x+5y=4 multiply by -2 to get -6x-10y= -8

Add together -19y=19, y= -1

Put y into either equation => 2x-3(-1)=9, 2x+3=9, 2x=6, x=3

ella [17]

Answer:

$\$6825$

Step-by-step explanation:

Amount deducted for Medicare = $725

Amount deducted for state income tax = $3000

Amount deducted for Social security = $3100

To find: Total amount deducted from Alton's pay for FICA last year

Solution:

Total amount deducted from Alton's pay for FICA last year = Amount deducted for Medicare + Amount deducted for state income tax + Amount deducted for Social security = $725+3000+3100$

On adding 725 and 3000, we get $725+3000=3725$

On adding 3725 and 3100, we get $3725+3100=6825$

So, amount deducted = $\$6825$

A company that makes? hair-care products had 7000 people try a new shampoo. Of the 7000 ?people, 42 had a mild allergic reaction

hram777 [196]

Answer: Percent of people who had a mild allergic is 0.6%.

Step-by-step explanation:

Since we have given that

Total number of people try a new shampoo = 7000

Number of people had a mild allergic reaction = 42

We need to find the "Percentage of people had a mild allergic":

Percentage of people had a mild allergic is given by

$\frac{\text{ Total number of people who had a mild allergic}}{\text{ Total number of people}}\times 100\\\\=\frac{42}{7000}\times 100\\\\=\frac{42}{70}\\\\=0.6\%$

Hence, Percent of people who had a mild allergic is 0.6%.
