Answer:

2.5(x)+6=3.25(x)+3 4=x. Real world problem below

Step-by-step explanation:

Nico is organizing a party. Going skating, admission is 6 dollars, and each person pays 2.5 dollars for a pair of skates. If he has 3 other people in his group, the equation is 2.5(4)+6=24. He is also looking at going to a trampoline park. It is 3 dollars to get in, and 3.25 per person for an hour on the trampolines. This equation can be shown as 3.25(4)+3 which equals 24.

Explain how you might use the properties of multiplication to solve 5 × 120 × 6.232 mentally. Then solve.

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, we apply the associative property that calculates the given value, which can be defined as follows:

Rule:

$\bold{\to (A\times B)\times C= A \times (B\times C)}$

Let,

$A= 5\\B=120\\C=6.232$

put the value in the above rule:

Solve L.H.S part:

$\to (5\times 120)\times 6.232\\\\\to (600)\times 6.232\\\\\to 3,739.2$

Solve R.H.S part:

$\to 5 \times (120 \times 6.232)\\\\\to 5 \times 747.84\\\\\to 3,739.2$

So, L.H.S=R.H.S
