Answer:

19

Step-by-step explanation:

231 - 7a = 98 = -7a + 231 = 98

Subtract 231 from both sides to get -7a = -133

Divide by -7 on both sides to get a = 19

Answer:

a = 19 is the correct solution.

Step-by-step explanation:

<u>Step 1</u> : Start by simplifying both sides of the problem.

231 − 7a = 98

231 + − 7a = 98

−7a + 231 = 98

<u>Step 2</u> : Next step is to subtract 231 from both sides

−7a + 231 − 231 = 98 − 231

−7a = −133

<u>Step 3</u>: Finally, divide both sides by -7.

( When I use the symbol /, it signifies I'm dividing.)

-7a/-7 = -133/-7

-133 divided by -7 equals 19

This shows that a = 19. I hope this helps! :D

If one letter is chosen at random from the word refuse what is the probability that the letter chosen will be an e
mrs_skeptik [129]

Answer: 1/3

Step-by-step explanation: The probability is given by the number of times the event could happen (in this case get an "e"), over the number of all the possibilities (in this case, the six letters of the word)

Therefore, probability \frac{letter_e}{all letter}=\frac{2}{6} =\frac{1}{3}

Rewrite 8x - 7 as the product of two factors
kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example:  4 can be broken into 2 factors---2 and 2.  2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor.  A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So:  8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to the line 4x – 3y =
vazorg [7]
The slope of the line given its equation is calculated through, m = -A / B. The slope of the given line is 4/3. The line perpendicular to it has the slope of -3/4. The slope-point form of the equation is, 
                                       y - y1 = m(x - x1)
where m is the slope and x1 and y1 the abscissa and ordinate of the point, respectively. 
Substituting the values above, 
                                       y --2 = (-3/4)(x - 3)

Simplifying the equation gives 3x + 4y = 1.
