Two numbers are in the ratio of 3:4. If they sum of the numbers is 63, find the numbers

Mathematics
1 answer:
Aleonysh [2.5K]2 years ago
6 0

Answer:

27 and 36

Step-by-step explanation:

Let's call the two numbers x and y.

3x=4y \\\\x+y=63

If you subtract y from both sides of the second equation, you can isolate x and substitute it into the first equation:

x=63-y \\\\3(63-y)=4y\\\\189-3y=4y\\\\189=7y\\\\y=27\\\\x=63-27=36

Hope this helps!

Which is a rule that describes the translation of a point from (–5, 4) to (–1, 2)?
Ket [755]

Answer:

B

Step-by-step explanation:

Given the translation (- 5, 4 ) → (- 1, 2 )

Note the x- coordinate of the translation is 4 more than the x- coordinate of the original x- coordinate, that is - 5 → - 1 is + 4

The y- coordinate of the translation is 2 less than the y- coordinate of the original y- coordinate, that is 4 → 2 is - 2

Thus the translation rule is

(x, y ) → (x + 4, y - 2 ) → B

Step-by-step explanation:

By using the equation y=2x, eval the following points (gathered from the attached picture)

1. (2,4) which leaves us 4=2*2

2. (4,8) which leaves us 8=4*2

3. (5,10) which leaves us 10=5*2

Which number line shows the solution set for |y-9| <12
RUDIKE [14]

Answer:

Option c

y\geq-3 or y \leq 21

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function f(x) = |x|  x> 0 for all real numbers.

Then the inequation:

|y-9| \leq 12 has two cases

(y-9)    if y \geq 9  (i)

-(y-9)    if y < 9 (ii)

We solve the case (i)

y \leq 9 + 12\\y\leq21

We solve the case (ii)

-y +9 \leq 12\\-y \leq 12-9\\y \geq -3

Then the solution is:

y\geq-3 or y \leq 21
