Answer:
63
Step-by-step explanation:
There is 90 deaths per day.
First it tells us 32,400 people died in 2015, which also mean that many people died that year.
We have to find the number of people died each month first.
32,400÷12 because 12 is the total number of months in a year.
2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get
90 deaths per day.

Answer:
The 16 oz jar
Step-by-step explanation:
12 oz jar
Cost = 8.65/12
Cost = $0.72/oz
=====
16 oz jar
Cost = 10.99/16
Cost = $0.69/oz
=====
24 oz jar
Cost = 16.99/24
Cost = $0.71/oz
The 16 oz jar costs less per ounce.
To find out which size jar of macadamia nuts offers the best value, calculate the price per ounce for each size. The results show that the 16 oz jar provides the best value as it has the lowest cost per ounce.
To determine which size jar of macadamia nuts offers the best value, you will need to calculate the price per ounce for each jar.
Based on these calculations, the 16 oz jar offers the lowest cost per ounce, making it the best value for these macadamia nuts.

Answer:
x =-2 and z =-4
Step-by-step explanation:
We need to solve the following systems of equation
-3x-2y+4z = -16 eq(1)
10x+10y-5z = 30 eq(2)
5x+7y+8z = -21 eq(3)
Multiply eq(1) with 10 and eq(2) with 3
-30x-20y+40z = -160
30x+30y-15z = 90
__________________
10y+25z = -70
Divide by 10
2y+5z = -14 eq(4)
Multiply eq(1) with 10 and eq(3) with 6
-30x-20y+40z = -160
30x+42y+48z = -126
__________________
22y+88z = -286
Divide by 11
2y+8z = -26 eq(5)
Subtract eq(4) and eq(5)
2y+5z = -14
2y+8z = -26
- - +
__________
-3z = 12
z = 12/-3
z = -4
Putting value of z in eq(4)
2y+5z = -14
2y +5(-4) = -14
2y = -14 +20
2y = 6
y = 3
Putting value of z and y in eq(1)
-3x-2y+4z = -16
-3x-2(3)+4(-4) = -16
-3x -6 -16 = -16
-3x = -16+16+6
-3x = 6
x = 6/-3
x = -2
