Isabella earns $9.50 per hour. She would've earned $475 for the entire 50 hours.
Answer:
Yumiko should multiply the other equation by 3.
If she adds the two equations she would be left with the variable 'x'.
Step-by-step explanation:
Given the two equations are as follows:


It is given that she multiplies the first equation by 6. Therefore, (1) becomes

Now, note that the sign of the variable 'y' is negative. So, if we make the co-effecient of 'y' equal in both the cases, add them it would result in the elimination of the variable 'y'.
The co-effecient of y in Equation (2) is 6. To make it 18 like it is in Equation (1), we multiply throughout by 3.
Therefore, Equation (2) becomes:

Now, we add Equation (a) and Equation (b).


Factor: 3
Equation: 27x = 126
Answer)3.5
1)minus 17.5-14=3.5
2)14+3.5=17.5
3)keep adding 3.5
Just use y2-y2/x2-x1
so
1+5 (because subtracting a negative is the same as adding a positive)
4-2
6/2
or 3/1 which is the same as 3
The answer should be 15/24 of an ouce beacause 35 minus 5 ounces because the box weighs 5 ounces when it is empty. Then, you need to do 30 dibided by to to get 30/48 which is reduced to 15/24.
