Liam bought 5 7/8 pounds of steak. He used 2 1/16 pounds of the steak for a cookout. Liam has about how many pounds of steak remaining after the cookout?

Answers

Liam bought a total of 5 7/8 pounds of steak. Then he used 2 1/16 pounds of steak for a cookout.Given with the data above, let's find out how many pounds were left after he used some of it.=> Notice that the given numbers are fractions> => 5 7/8 pounds and 2 1/16 poundsSince these are mixed fraction, let's convert it to improper fraction. => 5 7/8 = (8 * 5 = 40 + 7 = 47) = 47 / 8=> 2 1/16 = (16 * 2 = 32 + 1) = 33 / 16The equation is now = 47/8 - 33/16=> Since they don't have the same denominator, let's find the lCD=> 47/8 - 33/16 = 94/16 - 33/16 = 61/16Let's change it to mixed fractions=> 61 /16 = 3.8 or => 3 . 8/100 = 3 2/25

Annabel and Riley were given a homework packet of 120 math questions to finish over the summer. In June, Annabel finished 25% of the questions in her packet.
In June, Riley finished 40% of the questions in her packet.

How many more questions had Riley finished than Annabel?

Answers

Riley finished 18 more questions than Annabel, as per the given condition.

Given that,
Annabel and Riley were given a homework packet of 120 math questions to finish over the summer. Annabel finished 25% of the questions in her packet. In June, Riley finished 40% of the questions in her packet.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Question finished by Annabel = 25% of 120 = 0.25 × 120 = 30
Question finished by Riley= 40% of 120 = 0.40× 120 = 48
Difference in the question = 48 - 30 = 18

Thus, Riley finished 18 more questions than Annabel, as per the given condition.

(559 – s) + 544

for s = 171.

Answers

(559 - s) + 544

(559 - 171) + 544

Order of Operations:
PEMDAS

P = Parenthesis
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction

(388) + 544

(559 - 171) + 544 =388 + 544 =932

What is the value of y?6(5 + 3) = 6 • 5 + 6 • y





y =

Answers

Divide the equation by six to get:

5+3=5+y

Subtract 5 from both sides to find that y=3.
6(5 + 3) = (6 *5) + (6 * y) ~~\to~~ 6(8) = 30+ 6y \to 48 = 30 + 6y

6y=18 \to y=3

y=3
