Answer:
Associative Property of Multiplication
[ 3(5) (4) = (3) 5(4)]
Identity Property of Multiplication
5(1) = 5
Identity Property of Addition
(3 + 5) + 0 = (3+5)
Commutative Property of Addition
3 + 5 = 5 + 3
Associative Property of Addition
3 + (5 + 7) = (3 + 5) + 7
Step-by-step explanation:
The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.
The identity property of 1 says that any number multiplied by 1 keeps its identity.
Hoped this helped!
Answer:
Perimeter = 28.8 inch
Step-by-step explanation:
Step 1: Change given centimeters into inches according to the scale
2.5 / .5 = 5 <--- length in inches
4.7 / .5 = 9.4 <--- width in inches
^^^This is the same thing as multiplying 2.5 cm and 4.7 cm by two. You could also reword the scale to be 1 cm = 2 inch if it makes more sense for you
Step 2: Find the perimeter using the formula: P = 2L + 2W
2 (5) + 2(9.4)
10 + 18.8
Answer:
x+ 3/2y= 15
Step-by-step explanation:
8x+12y=120
To put the equation into standard form, the leading coefficient has to be 1. So, divide the whole equation by 8.
x+ 3/2y= 15
Answer:
y = 7
Step-by-step explanation:
3 × (3y - 4) = 51 multiply 3 with inside the parenthesis
9y - 12 = 51 add like terms
9y = 51 + 12
9y = 63
y = 7
