Answer:
2x + 5y = 4.70
Step-by-step explanation:
Rider ordered 2 hot dogs and 5 hush puppies. His total was $4.70. Write an equation in standard form for this relation, using
From the above question, note that
x = cost of a hot dog
y = cost of a hush puppy.
Our Standard Equation is given as
2 × x + 5 × y= $4.70
2x + 5y = 4.70
Answer:
780
Step-by-step explanation:
So when you're adding consecutive numbers like this. 1+2+3...+39. You add 39 and 1. This is 40. 2+38 is 40. This is a pattern. Now, we do 40 multiplied by 39 and this will give you the number 1620. After this you would have to divide this product by 2. The answer will soon be 780.
Y = 4/x
so when x = 1 y = 4/1 = 4
answer is A. (1,4)
Answer:
1/7776.
Step-by-step explanation:
The probability of rolling a six in 1 throw = 1/6.
Rolling a 6 5 times in a row = (1/6)^5
= 1/7776.
The probability is multiplied because each roll is independent from other rolls.
