Four friends went to the movies each ticket cost $8 and each person bought popcorn and a soda for $5 how much did they spend in
Neporo4naja [7]
Answer: m = $52

Explanation:
Tickets (t) = $8
Popcorn & Soda (s)= $5
Friends = 4
Since all friends bought the same thing the equation will be set as
4(t +s) = m OR 4t +4s = m
Using substitution, you plug each variable
t = 8 and s = 5
4((8) + (5)) = m
4(8+5) = m => 4(13) =m => 52=m
OR
4(8) + 4(5) = m => 32 + 20 = m =>
52 =m

Jaclyn estimates that the square root of 50 in the following way: √50 = 2√25 = 2*5 = 10
Harman [31]

Answer:

Jacklyn is wrong because

\sqrt{50}   \ne2 \sqrt{25 }

Step-by-step explanation:

We have that :Jaclyn estimates that the square root of 50 in the following way:

\sqrt{50}  = 2 \sqrt{25}

\sqrt{50}  = 2 \times 5

\sqrt{50}  = 10

Jacklyn is wrong because she made an error at

\sqrt{50}  = 2  \sqrt{25}

The correct expression is

\sqrt{50}  = \sqrt{2 \times 25}

This gives:

\sqrt{50}  = \sqrt{ 25}  \times  \sqrt{2}

\sqrt{50}  =5 \sqrt{2}

Because of 2.16 yds over 1 times 1 meter over 3 yds. You divide them instead of multiplying, you get 1.97 meters.
