Answer:
y=26.67
Step-by-step explanation:
The given equation is 0.75x+1.5y=40.
We need to show the result of substituting x=0 in above equation.
0.75x+1.5y=40
Put x = 0
0.75(0)+1.5y=40
0+1.5y=40
⇒ 1.5y=4
So, the value of y = 26.67 when x = 0.

Answer:</h2><h2>(i) Total expenses = $ 300</h2><h2>(ii) Net income(savings) = $ 0</h2>
Step-by-step explanation:
Total income earned by Sam = $ 300
(i) Expense calculation,
Clothes expense = 30 % = 30 % (300) = $ 90
Food and snacks expense = 23 % = 23 % (300) = $ 69
Cell phone expense = 14% = 14% (300) = $ 42
Transportation expense = 10% = 10% (300) = $ 30
Gym expense = 10% = $ 30
Movies expense = 8% = 8% (300) = $ 24
Apps expense = 5% = 5% (300) = $ 15
Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300
(ii) Sam's net income is the profir earned after his expense.
Net income = 300 - 300 = $ 0
First, distribute the (1/2) into (4x+12) by multiplying them.
The equation becomes:
2x + 6 + 5x = 30
On the left side, combine “like terms” through addition.
7x + 6 = 30
Subtract 6 from both sides:
7x = 24
Finally, get x alone by dividing both sides by 7:
x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.
Answer: 1.83
Step-by-step explanation:
Z = (x - mean) / standard deviation
= (97-75) / 12
= 22/12 = 11/6 = 1.83
Answer:
the answer is 2
Step-by-step explanation:
14=z-(-12)
