One positive number is 5 times another number and the difference between the two numbers is 1044, find the numbers.

1 answer:

8 0

The equation is: 5x - x = 1044
Now, What you have to do here is simple.
First, subtract x from 5x and you get 4x.
4x =1044
Here you divide both sides by 4. 4x becomes x and 1044 becomes 261.
x = 261
We have the first number. To get the other one we have to multiply 261 by 5.
261 * 5 = 1305
the answer is 1305

So:
x= 261
5x=1305

Hope you understand.

the sum of three times one number, x, and five times a second number,y, is 77. if the sum of the two numbers is 19, find the two

HACTEHA [7]

Answer:

x=9, y=10. (9, 10). The two numbers are 9 and 10.

Step-by-step explanation:

3x+5y=77

x+y=19

------------------

3x+5y=77

-3(x+y)=-3(19)

---------------------

3x+5y=77

-3x-3y=-57

-------------------

2y=20

y=20/2

y=10

x+10=19

x=19-10

x=9

In triangle ABC, a = 4, b = 6, and cos C = − 1/4. What is the length of side c?

shusha [124]

The length of side c would be 8.

Step-by-step explanation:

Given that,

a = 4

b = 6

cosC = -1/4

If we are given two sides and angle, the law of Cosines can be used to find the third side:

$c^{2} = a^{2} + b^{2} - 2ab (cos(c))$

By inserting the values in the formula, we get

$c^{2} = 4^{2} + 6^{2} - 2.4.6 (-\frac{1}{4} )$

$c^{2} = 16 + 36 + 12$

$c^{2} = 64$

$\sqrt{c^{2} } = \sqrt{64}$

c = 8.

Therefore, the length of side c would be 8.
