Sum of two numbers is 95. If one exceeds the other by 25,<br> find the numbers.<br><br> Pls answer
Nitella [24]

Answer:

60 and 35

Step-by-step explanation:

Let:

First number = x

Second number = y [ y > x ]

According to question:

x + y = 95

= > y = 95 - x .... ( i )

y = x + 25 ...... ( ii )

From ( i ) and ( ii ) we get:

95 - x = x + 25

= > 2x = 70

= > x = 35

y = 95 - x [ x = 35 ]

= > y = 60

Therefore numbers are 60 and 35.

Can somebody help me please !?
r-ruslan [8.4K]

Answer:

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = \frac{7\sqrt{3} }{x}

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.

27x+3=6<br> Whats is x in that problem
Lilit [14]

Answer:

x=1/3

Step-by-step explanation:

You have to isolate the variable, so you must first separate the constants from the variable. Add 3 on both sides to cancel out the minus three and to move it to the other side. Now you have 27x=9. It's pretty simple from there just use your calculator and divide 27x/27 and also 9/27. That leaves you with 1/3
