We know that in 2 ½ hours (2.5 hours), we can create 3
cakes hence:
C = k t
where C is number of cakes, k is constant, and t is time
k = 3 cakes / (2.5 hours)
k = 1.2
C = 1.2 t
So for t = 7 ½ hours = 7.5 hours
C = 1.2 (7.5)
<span>C = 9 cakes in 7 ½ hours</span>
Answer:
y = -1 + -0.75x
explanation:
The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction). This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6). Because of this, Omar did not need to use a grouping symbol.
Answer: Joe's weekly allowance = $12
Step-by-step explanation:
Joe spent half of his weekly allowance playing mini-golf
Let a = his weekly allowance
This means Joe spent a/2 playing mini-golf.
To earn money, his parents let him weed the garden for $6
This means Joe's total money
= a + 6
What is his weekly allowance if he ended with $12?
This means he had $12 left after spending a/2 from ta total of (a +6)
Therefore,
(a +6) -a/2 = 12
Taking LCM of 2
[2(a+6)-a]/2=12
Cross multiplying by 2
2a + 12-a = 24
a+12 =24
a = 24-12 =$12
Joe's weekly allowance = $12
