Answer:
D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Step-by-step explanation:
Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.
or, for any numbers A, B and C
A + ( B +C) = (A +B) + C
Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Answer:
$ 1249.6
Step-by-step explanation:
given,
cost of saddle = $534.00
riding chaps cost = $87.02
boots cost = $143.99
hat cost = $55.87
pairs of glove cost = $15.94
sales tax paid = 7.5%
Sam's lesson cost = $35.00 per lesson
number of lesson = 10
Total purchase cost
= $534.00 + $87.02 + $143.99 + $55.87 + $15.94
= $ 836.82
cost included sales tax
= 1.075 x $ 836.82
= $ 899.58
Cost of lesson = 10 x $35.00 = $350.0
Total cost of the Sam
= $ 899.58 + $350.0
= $ 1249.58
= $ 1249.6
Answer:
22 units
Step-by-step explanation:
The perimeter of a rectangle is 2(width + length)
In this case width = 2z + 2 and length = 3z + 3
replacing everything known:
110 = 2(2z + 2 + 3z + 3)
110/2 = (5z + 5)
55 = 5z + 5
55 - 5 = 5z
50 = 5z
10 = z
Segment PQ is the same as SR = 2z + 2
Replacing z = 10
PQ = 2(10) + 2
