2k - 2j when j=4&k=6 replace the variable with the given amount and solve the problem

eimsori [14]

Answer:

4

Step-by-step explanation:

first, plug in 6 for k. (it doesn't matter which value you plug in first; you can start with j or k, but i'm just starting with k since that is the variable that comes first in the expression)

2k - 2j => 2(6) - 2j

then plug in 4 for j.

2(6) - 2j => 2(6) - 2(4)

now your expression is 2(6) - 2(4). simplify by multiplying 2(6) and then -2(4) (again, it doesn't matter which one you multiply first, as long as you make sure that the minus sign between 2(6) and 2(4) gets attached to the 2 in 2(4).)

2(6) - 2(4) => 12 - 2(4)

12 - 2(4) => 12 - 8

subtract 8 from 12.

12 - 8 = 4

your answer is 4, therefore when j = 4 and k = 6, 2k - 2j = 4.

i hope this helps! have a nice day <3

Jessica has $50 to spend on new clothes. The jacket that she wants to buy is $48.20. If the tax rate is 6% does Jessica have eno

Virty [35]

Answer:

Step-by-step explanation:

She has 50$. A jacket is on for 48.20$. The tax is 6% of the product you buy.

6% = 0.06

To find 6% you do:

0.06*48.20

Which is 2.892.

You ADD 2.892 to the price.

48.20+2.892=

51.092. Round it:

51.09 > 50.00

No, she does not have enough.

Answer:

25%.

Step-by-step explanation:

Let E be the event that the dart lands inside the triangle.

We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.

We know that probability of an event represents the chance that an event will happen.

$\text{Probability}=\frac{\text{Favorable no. of events}}{\text{Total number of possible outcomes}}$
