Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r

Aleks [24]

Answer:

The expression that represents her gross pay each day will be: $(5h+8)$ dollars.

Step-by-step explanation:

Suppose, Harriet's gross pay each day $= x$

So, her total gross pay for 7 work days $=7*x= 7x$

Given that, her gross pay at the end of 7 work days is $(35h + 56)$ dollars.

So, the equation will be.......

$7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8$

Thus, the expression that represents her gross pay each day will be: $(5h+8)$ dollars.

Z varies directly as x and y, z = 6 when x=2 and y = 6. Find the value of z when x = 3 and y = 8

Monica [59]

Answer:

12

Step-by-step explanation:

This is a joint variation problem:

z varies directly as x and y

Interpreting this;

z ∝ xy

Therefore;

z = kxy

z = 6, x = 2, y = 6

Now find k,

6 = 2 x 6 x k

6 = 12k

k = $\frac{1}{2}$

To find the value of z;

x = 3, y = 8

z = $\frac{1}{2}$ x 3 x 8 = 12
