Which is an equivalent expression to 45j + 90k?

A.5(9j + 20k)
B.5(9j + 90k)
C.15(3j + 6k)
D.15(3j + 90k)

Answers

Answer 1
C



15(3j + 6k)

15•3j= 45j

15•6k=90k

45j+90k
Answer 2

C. 15(3j + 6k)

What is simplification?

Combining operands with a single arithmetic operator specifies a Simplification. A few examples of built-in functions that may be used to define mathematical processes are adding, subtracting, dividing, and multiplying. Typically, PEMDAS is used to compute various arithmetic operations.

Given an equation 45j + 90k. in this equation if we want to find out the magnitude and vector value of the equation then we have to separate the by simple simplification term by taking common from both vectors.

Hence after taking 15 commons, the remaining equation will be 15(3j + 6k).

Therefore,  an equivalent expression to 45j + 90k is 15(3j + 6k).

What is distance between two points?

The distance between two points is the length of the line segment joining them.

Given that a coordinate plane, a rectangle has 4 points. Point W is (-5, 3), point X is (0, 3), point Y is (0, -1), and point Z is (-5, 0).

Distance between two points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Therefore,

XY = [tex]\sqrt{(0-0)^2+(-1-3)^2}[/tex]

XY = [tex]\sqrt{4^2}[/tex]

XY = 4

Hence, the length of side XY on the coordinate plane is 4 units.

Given the proportional steel cost, how much do 200 pounds of steel cost?

Answers

Answer:

Your answer is B, 150

Step-by-step explanation:

If we look at the chart it says 160 pounds of steel is 120, so for example if we start from 40 we will have 30, so every time we add 40 pounds 30$ are added, meaning that 160+40=200, 120+30= 150, Thus B or 150 is our answer.

Answer:

$150

Step-by-step explanation:

Hi,

We know that 160Ibs of steel costs $120. To find the cost of 1Ib of steel, we have to divide both 160Ibs and $120 by 160. Here's what I mean...

Total amount: 160Ibs

Divide by 160...

Total amount: 1Ib

Total cost: $120

Divide by 160...

Total cost: $.75

That means that each pound of steel costs $.75

Now, multiply by 200 to get the total cost if you buy 200Ibs of steel...

200 x .75 = 150

The total cost would be $150

Hope this helps :)
