Answer:
the second one
Step-by-step explanation:
we dont know if the sides are congruent but we do know we have one height, one lenght, and one width. we have to find the area of two of each, and thats what the second one is
Answer:Mixed number = a whole number and a proper fraction, of the same sign.
Proper fraction = numerator smaller than denominator.
35 ÷ 2 = 17 and remainder = 1 =>
35 = 17 × 2 + 1 =>
35/2 =
(17 × 2 + 1) / 2 =
17 + 1/2 =
17 1/2
Step-by-step explanation:
Doubles are adding the same number together, as with 5+5=10.
With doubles +1, the numbers must be in beside each other in counting order going up or down (ex: 4, 5, 6 and 9, 8, 7). Do the SMALLEST number, double it, then add one. So, 9+8 would be 8+8=16, +1=17. You must know your doubles facts before this strategy is useful.
Answer:
Step-by-step explanation:
Let x be the number of adult tickets and y be the number of children's tickets.
We are given that there are total 12 people. Therefore, we can set:
Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be 
and cost of y children's ticket will be 
. We can form the second equation by setting the total cost of tickets as:
Therefore, the required system of equations that could be used to find x and y will be:
