What is an Inequality?

The relationship between two expressions or values that are not equal to each other is called inequality.

Given that three times, the sum of a number n and 5 is at least 17.

According to the question, the expression will be = 3(n+5)≥17

Hence, 3(n+5)≥17 is the expression for three times the sum of a number n and 5 is at least 17.

If 30 percent of a numbers equlas 8 find 90 percent of that number

Answers

Answer:

Step-by-step explanation:

So 30% of the a number is 8.

Lets call this number x

So we write this down as 30/100 of X=8

by cross multiplying you get X=26.67

So 90/100 of 26.67=24.003

An SUV costs $27,070 and costs an average of $0.18 per mile to maintain. A hybrid model of the SUV costs $32,880 and costs an average of $0.13 per mile to maintain. After how many miles will the cost of the gas-only SUV exceed the cost of hybrid?

Answers

Answer:

116,200 km

Step-by-step explanation:

Here we have 2 cars, each one with it's corresponding costs. Let's write each cost as functions. The SUV costs $27,070 plus $0.018 per mile. Let x be the miles and SUV (x) the SUV's cost:

SUV(x)=27070+0.18x

We can do the same for the hybrid with a cost function H(x):

H(x)=32880+0.13x

We now need the cost of the SUV to be greater than the hybrid. This is SUV (x)> H(x):

27070+0.18x > 32880+0.13x

Let's subtract 27070 in each side:

0.18 x > 32880 - 27070 + 0.13x

Now let's subtract 0.13x in both sides:

0.05x > 5810

Divide both by 0.05:

x > 5810/0.05

x > 116,200

So, after 116,200km the SUV will turn to be more expensive.
