Flying lessons on weekdays cost m dollars per hour. Flying lessons on weekends cost 1.2m dollars per hour. The expression 9m+3(1

lbvjy [14]

Answer:

The cost of lesson for 9 hours on weekdays and 3 hours on weekends

Step-by-step explanation:

Given

$Weekdays = \$m /hour$

$Weekends = \$1.2m/hour$

Required

What does 9m + 3(1.2m) represent

The expression can be split to:

9m and 3(1.2m)

For 9m:

From the question, we understand that:

$m = 1\ hour$

Multiply both sides by 9

$9 * m = 1\ hour * 9$

$9 m = 9\ hours$

This means that:

9m = the cost of lessons for 9 hours on weekdays

For 3(1.2m):

From the question, we understand that:

$1.2m = 1 \ hour$

Multiply both sides by 3

$3 * 1.2m = 1 \ hour * 3$

$3(1.2m) = 3 \ hours$

This means that:

3(1.2m) = the cost of lessons for 3 hours on weekends

Hence, the expression represents:

The cost of lesson for 9 hours on weekdays and 3 hours on weekends

How do you get the answer

I am Lyosha [343]

Plug in -2 for a, 3 for b, and -5 for c. Then it'd be | (-3)^2 - 2(-2)(-5) +5 (3) |. Then, multiply everything to get | 9 -20 +15 |. Then, add/subtract to get | 4 |. Finally, take the absolute value and get 4.

Jim’s sleeping bag is 5 feet long.Jorge’ sleeping bag is 2 yards.Stevens sleeping bag is 68 inches,Whose sleeping bag is longer

Mariulka [41]

Well, we know 1 yard is 3 feet, so 2 yards is 6 feet. That makes Jorge's sleeping bag longer than Jim's. (6 feet is longer than 5 feet)

We also know that 1 yard is 36 inches, so 2 yards is 72 inches. That makes Jorge's sleeping bag longer than Steven's. (72 inches is longer than 68 inches)

Since Jorge's sleeping bag is longer than both Jim's and Steven's, Jorge's sleeping bag is longer.
