Ten as each term is the coefficient and the variables if one is listed for example 2x is one term. For ex as is -4z2x and the 3 etc.
Answer:
1.50
Step-by-step explanation:
X = hot dog price
Y = hamburger price
5X + 4Y = 16.50
4X + 5Y = 17.25
4(5X + 4Y = 16.50)
20X + 16Y = 66
5(4X + 5y = 17.25)
20X + 25Y = 86.25
Now subtract the equations:
20X + 16Y = 66
20X + 25Y = 86.25
9Y = 20.25
Y = 2.25
Hamburger is $2.25
4X + 5(2.25) = 17.25
4X + 11.25 = 17.25
4X = 6.00
X = 1.50
Hamburgers are $2.25
Hotdogs are $1.50
The expression would be:
3*8+4
3 times 8 plus 4

Answer:
D. 8
Step-by-step explanation:
y varies jointly as x and z
y = k(xz)
-------------------------
Find k, the constant of variation
y = 12 when x = -2 and z=3
12 = k(-2 * 3)
12 = k(-6)
k = -2
-------------------------
find y when x is 4 and z is -1
using k = -2
y = -2(4 * -1)
y = -2(-4)
y = 8
