Answer:

"$/km"

Step-by-step explanation:

He wants to model "maintenance cost" with respect to "distance"

Normally,

maintenance cost would be in currency --- dollars, pounds etc.

distance would be in kilometers, miles, meters etc.

We need to find the ratio that has the COST on top and DISTANCE on bottom

Looking at the choices,

We can eliminate 1st and 3rd immediately as it doesn't have COST on top.

That leaves us with

$/km

and

km/$

$ is in fact currency and unit for cost and km is in fact unit for distance. We need the ratio that has $ on top and km on bottom, that's the 2nd option.

So, $/km is the appropriate unit.

Answer:

B. Step 4 is incorrect , it should be \frac{10}{8}

Step-by-step explanation:

6x-1= -2x+9

Step 1

Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1

Step 2: Add like terms on both sides

8x = 10

Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;

\frac{8x}{8} = \frac{10}{8}

The two 8s cancel each other and you remain with x=\frac{10}{8}

The larger of two numbers is 12 more than the smaller number. if the sum of the two numbers is 74 find the two numbers.
STatiana [176]
Hi there!

Let th' two number be ' a ' and ' b ' [ a > b ]

According to th' question :-

→ The largest of two numbers is 12 more than the smaller number.

a = 12 + b ---(i)

→ Sum of the two numbers is 74.

a + b = 74

b = 74 - a ---(ii)

Substitute th' value of ' b in Eqn. :-

a = 12 + (74 - a)

a = 86 - a

a + a = 86

2a = 86

a = \dfrac {86}{2} = 43

Now,
Substitute th' value of ' a ' in Eqn. (ii)

b = 74 - b

b = 74 - 43

b = 31

Hence,
The required answer is :-

• The smaller number is 31
• The largest number is 43

~ Hope it helps!
