How can you solve the literal equation y-3x=13

Answers

Answer 1
Answer: So to begin, you need to find x and y. If you have answer options, plug those in. If you don't, your toast. Just kidding :) 
So, your answer would be y3=13. I think you can handle the rest. 3 * what equals 13?

I am trying to figure out how to write out and solve: The first number is 5 less than the second number. Four times the first number plus 5 times the second number is 74. find the numbers

Answers

OK, I will try my best to help you out, young lad. Just kidding, I am young too!
OK, so first you have to assign variables.  
Let's make the first number = x-5
the second number is =x
Now, set up an equation
4(x-5)+5(x)=74
Use the distributive property to simplify the equation.
4x-20+5x=74
simplify the problem to find x
9x-20=74
9x=94
x=10.4 or 94/9
Now, apply the answer..
We know that the second number, x = 10.4 ( or 94/9), so the larger number is...
94/9 - 5= 49/4 of 5.4
so the answers are
first number= 5.4 (fraction form- 49/4)
second number= 10.4 (94/9)

Answers

The slope is 4.

What is slope?

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

given:

roof rises= 171 feet above the ground

horizontal distance = 6.5 yards

using,

Slope = (rise) / (run)

Rise

= (171-93)

= 78 ft

Run

= 6.5 yards

= 19.5 ft

Slope

= (78 / 19.5)

= 4

hence, the slope is 4.

Slope = (rise) / (run)

Rise = (171-93) = 78 ft

Run = 6.5 yards = 19.5 ft

Slope = (78 / 19.5)

Slope = 4

A bag contains 26 letters and 9 numerals. Aubrey draws two cards from the bag. What is the probability that she draws 2 numerals?

Answers

Assuming that she does not replace the first card, you have to combine the two probabilities of drawing a numeral, then drawing a numeral again. The probability of drawing a numeral is or 25.71%. The 35 is a count of all the cards in the bag. The probability that she draws a numeral the second time without replacing the first one is now: or 23.53%. Multiplying these together gets you: or 6.05%.
The probability is 34% because 9/26=.34615384615. The first 2 numbers makes the percentage
