Evaluate 3/7r + 5/8s when r = 14 and s = 8
emmasim [6.3K]

\frac{3}{7}*r + \frac{5}{8} *s

let us first plug the values of r and s here

r=14 and s=8

\frac{3}{7}*14 + \frac{5}{8} *8

Now here we can cancel 14 and 7 as 7*2 =14 , also we can cancel 8 and 8 as 8*1 is 8, so our simplified new form is:

\frac{3}{1}*2 + \frac{5}{1} *1

Now we can multiply 3*2 and 5*1

3*2 =6

5*1=5

Next we add the two numbers

6+5 =11

So this is how we get the answer 11

Find the value of x. Picture below
Wittaler [7]

Here a right angled triangle given. We know that one angle of a right angled triangle is 90°.

As the sum of three angles of a triangle is 180°, so we can say the sum of other two angles of a right angled triangle is (180-90)° = 90°.

Here in the figure the other two angles given (2x)^o and (x+15)^o. Sum of these two angles is 90°.

So we can write the equation as,

(2x)+(x+15) = 90

We have to remove the parenthesis now.

2x+x+15 = 90

Now we will add the like terms. Here x and 2x are like terms. By adding them we will get,

3x+15 = 90

To solve it for x, now we have to move 15 to the other side by subtracting it from both sides.

3x+15-15 = 90-15

3x= 90-15

3x= 75

Now to get x, we have to move 3 to the other side, by dividing it to both sides.

(3x)/3 = (75)/3

x = (75)/3

x = 25

We have got the required value of x.

The solution is x= 25.
