X= 40

Step-by-step explanation:

X ×2+5= Jonathan age.

So, 85÷2-5 = <u>X</u>

X= 85÷2-5

=<u>4</u><u>0</u>

Answer:

<h2>30 years</h2>

Step-by-step explanation:

Age of melvin = X

Age of Jonathon = X + 5

After 10 years,

Age of melvin = X + 10

Age of Jonathon = X + 15

Now,

According to the question,

x +10 + x + 15 = 85

Collect like terms

2x +10 + 15 = 85

Calculate the sum

2x + 25 = 85

Subtract 25 on both sides

2x + 25 - 25 = 85 - 25

Calculate

2x = 60

Divide both sides of equation by 2

\frac{2x}{2}  =  \frac{60}{2}

Calculate

x = 30

Hope this helps...

Good luck on your assignment..

What is 7 (1+10p) + 8 (1 + 6p)
Komok [63]

Answer:

58p+15

Step-by-step explanation:

First, we want to get rid of the parentheses in the equation. To do that, let's start with 7(1+10p). We multiply 7 by each item in the parenthesis, and get 7+70p. Keep that little thing in mind, we will use it later. Next, same process with the other part, and we get 8+48p. We multiplied both parts out, so now we just add like terms. 7 and 8 don't have letters, so we add them to get 15. 10p and 48p do have letters, so we add those together and get 58p. We can't add that to the other numbers, because 58p is 58 times p, and 15 doesn't have that p so it wouldn't work without knowing p. What we are left with, by simplifying the problem, is 58p+15, or 15+58p. The order doesn't matter, as long as you have that answer.

Answer:

0

Step-by-step explanation:

Substitute the given values for a and b into the expression

\frac{1}{2}(18 + 14) - (18 - 14)²

= \frac{1}{2} × 32 - 4²

= 16 - 16

The diameter of a circle has endpoints A(1, 3) and B(4, 7), what is the
lana [24]

Answer:

The circumference of the circle is 5π

Step-by-step explanation:

First we need to calculate the diameter  

for this we have to know the distance between A(1, 3) and B(4, 7)

X =  Xb - Xa

X = 4 - 1

X = 3

Y = Yb - Ya

Y = 7 - 3

Y = 4

b - a = (3 , 4)

now that we have the distance of x and r we can calculate its distance using Pythagoras

h = hypotenuse

x = leg 1 = 3

y = leg 2 = 4

h² = x² + y²

we replace the known values

h² = (3)² + (4)²

h² = 9 + 16

h² = 25

h = √25

h = 5

The diameter of the circle is 5

Now we need to calculate the circumferencefor this we need to use the circumferenc formula of a circle:

c = circumference

d = diameter = 5

π = pi

c = π * d

we replace with the known values

c = 5  * π

c = 5π

The circumference of the circle is 5π
