Answer:
4d (the variable is usually x, though).
Step-by-step explanation:
Because 4 x the amount of fish in each tank = total amount of fish
30 miles
Because you’re cutting the time in half and the same should apply to the speed
I believe the commutative property on multiplication
i hope this helped
The angle in the dilated figure is the same as the original angle in each case, a fact that should be confirmed by the way the answer choices are shown.
∠A = ∠A'
... 4x -4 = 51 -x
... 5x = 55
... x = 11
∠A = 4·11 -4 = 40 . . . . . . doesn't match any offered choice
___
∠B = ∠B'
... 6x -1 = 4x +21
... 2x = 22
... x = 11
... ∠B = 6·11 -1
... ∠B = ∠B' = 65 . . . . . matches selection D)
_____
∠C = ∠C'
... 8x -13 = 6x +9
... 2x = 22
... x = 11
... ∠C = 6·11 +9 = 75
... ∠C = ∠C' = 75 . . . . . matches selection D)
Answer:
<em><u>AT</u></em><em><u> </u></em><em><u>LEAST</u></em><em><u> </u></em><em><u>40</u></em><em><u> </u></em><em><u>STUDENTS</u></em><em><u> </u></em>
Step-by-step explanation:
first make an expression to represent the zoo and museum cost.
( x represents the number of students)
zoo: 10x +100
museum: 5x+250
second plug in numbers of students until you find the answer: <em><u>at</u></em><em><u> </u></em><em><u>least</u></em><em><u> </u></em><em><u>40</u></em><em><u> </u></em><em><u>students</u></em><em><u> </u></em>
