Answer:
20 people
Step-by-step explanation:
well we know that only going to the restaurant every person must pay $7
so we have only $3 extra
those 3 dollars times the number of people must give 60 dollars
so 20 people must go, to pay only $10
A.In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10.
correct:
90(10 - 12) = 90 · 10 - 90 · 12 or 90(10 - 12) = 90 · (-2)
"Centi" means 100 so there are 100 centimeters in a meter. 4 times 100 equals 400 so 4 meters is equal to 400 centimeters.
Answer:
Step-by-step explanation:
Answer: b = 5
Step-by-step explanation:
Here parallelogram wxyz has diagonals,
4b-6 and 2b+4
Since, If a parallelogram has a equal pair of congruent or equal diagonal it is called a rectangle.
Thus, if wxyz is a rectangle,
Then, 4 b - 6 = 2 b + 4
⇒ 4b = 2 b + 4 + 6
⇒ 4 b = 2 b + 10
⇒ 4 b - 2 b = 10
⇒ 2 b = 10
⇒ b = 5
Hence, for b = 5, wxyz is a rectangle.
