It will take Ahmad 12 hours to drive 864 miles

Step-by-step explanation:

Step 1: Find the speed of Ahmad.

Distance = 360 miles

Time = 5 hours

⇒ Speed = Distance/Time = 360/5 = 72 miles/hour

Step 2: Find the time required to drive 864 miles

⇒ Time = Distance/Speed = 864/72 = 12 hours

Answer:

$\displaystyle (-∞, 2\frac{1}{3}) ∪ (1, ∞) \\ \\ 2\frac{1}{3} > t \:OR\: 1 < t$

Step-by-step explanation:

3t + 2 < 7 OR −4t + 5 < 1

- 2 - 2 - 5 - 5

Manny is buying new clothes for school. He buys three shirts for $14.95 each and a tie for $12. Everything in the store is on sa

jasenka [17]

Given:

Cost of each shirt = $14.95

Cost of a tie = $12

Discount on Sale = 15% off

Manny buys three shirts and a tie.

To find:

The Manny's total cost.

Solution:

We have,

Cost of 1 shirt = $14.95

Cost of 3 shirt = 3 × $14.95

= $44.85

Cost of a tie = $12

Total cost before discount = Cost of 3 shirt + Cost of a tie

= $44.85 + $12

= $56.85

Everything in the store is on sale for 15% off. So,

$\text{Manny's total cost}=56.85-\dfrac{15}{100}\times 56.85$

$\text{Manny's total cost}=56.85-0.15\times 56.85$

$\text{Manny's total cost}=56.85-8.5275$

$\text{Manny's total cost}=48.3225$

Therefore, the Manny's total cost is $48.3225.

Describe the relationship between n and 4 that will make the value of the expression 7 times n over 4 greater than 7

Mazyrski [523]

Answer:

Any values for n that are greater than 4 will satisfy the expression

Step-by-step explanation:

We have the expression

7n/4 > 7 solve for n...

7n > 28 multiply by 4 on both sides

n > 4 divide by 7 on both sides,

n is greater than 4, so any value for n greater than 4 will satisfy the inequality
