Jane, Jasmine, and Jocelyn have record collections. Jane has 3 times as many records as Jocelyn has. Jasmine has 2 more than twi
dangina [55]
X = jane, y = jasmine, z = jocelyn

x + y + z = 56
x = 3z
y = 2z + 2

3z + 2z + 2 + z = 56
6z + 2 = 56
6z = 56 - 2
6z = 54
z = 54/6
z = 9 <==== jocelyn

x = 3z
x = 3(9)
x = 27 <=== jane

y = 2z + 2
y = 2(9) + 2
y = 18 + 2
y = 20 <=== jasmine

Use the commutative property of multiplication to identify which expression is equivalent to 6(2)(x).
11Alexandr11 [23.1K]
The commutative property is when you change the order but not the answer. To better understand what they are asking you, let's let x=1- 6 * 2 * 1=12; Answer A wouldn't be right because there are no 6,2, or x's. Remember you just change the ORDER not the GROUPING so Answer B is wrong too. Now Answer C and Answer D are left. Now you just need to look at the signs. 6(2) just means 6 TIMES 2 so pick the option with multiplication. So your answer is C. Hope I helped!

The equation y = 5.50x represents the cost y (in dollars) for x visits to the
mr Goodwill [35]

In Graph x-axis represents number of visits and y-axis represents cost.

As graph comes up to be a linear one, so we can clearly say that cost is increasing linearly in multiples of 5.5 with increase in number of visits.

Example :

If museum is visited once then cost (y) = 5.5 x 1 = 5.5

If museum is visited twice then cost (y) = 5.5 x 2 = 11

If museum is visited thrice then cost (y) = 5.5 x 3 = 16.5

... cost (y) goes on in creasing when number of visits (x) increase with multiples of 5.5
