First lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
1 kg --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09
Answer: 48
Step-by-step explanation:
From the question, we are informed that it takes 12 buckets of water to fill a fish tank. We are further told that Chloe uses scoops which are equal to 1/4 of a bucket.
The number of scoops that are needed to fill the whole tank would be:
= 12 ÷ 1/4
= 12 × 4
= 48
It is an equation you have to solve.
m times p / n
mp/n
Answer:
98
Step-by-step explanation:
k = 7
2k^2
do the exponent
7 x 7 = 49
49 x 2 = 98
Answer:
f⁻1(x)=(x/7)+(5/7)
Step-by-step explanation:
To find the inverse, interchange the variables and solve for y.
