A + c = 405 <br> 12a + 5c = $3,590

SOVA2 [1]

Answer:

a=223.57

c=181.43

Step-by-step explanation:

a=405-c

substitute for a in the equation :

12a+5c=3590

12(405-c)+5c=3590

4860-12c+5c=3590

-7c=3590-4860

-7c=-1270

c=1270/7=181.43

a=405-1270/7

a=1565/7=223.57

Fill in the blanks, using the Associative Property of Multiplication: (8 X 1) 3 = 8 x ( x 3) - = 8x

hammer [34]

Step-by-step explanation:

Consider the provided multiplication.

We need to use associative property of multiplication.

Associative property of multiplication:

$(a\times b)\times c = a\times (b\times c)$

Now use the above property and solve the provided multiplication:

$(8 \times 1)\times 3 = 8 \times (1 \times 3)$

$8\times 3 = 8 \times 3$

$24 = 24$

The multiplication is verified by associative property.
