Hi there! Hopefully this helps!

<h2 /><h2>Answer: 235.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

First we need to substitute the value of the variable into the expression:

10a - 5b = 10(25) - 5(3).

Now we Multiply 10 and 25 to get 250.

250 − 5 × 3 = 235

Multiply 5 and 3 to get 15.

250 − 15 = 235

<h2>Subtract 15 from 250 to get, you guessed it, 235!</h2>

Answer:

$\boxed{235}$

Step-by-step explanation:

Hey there!

Well given that,

a = 25

b = 3

10(25) - 5(3)

250 - 15

= 235

Hope this helps :)

If 3x + 2y = 1 and 2x + 7y = 3 How do you find x and y step by step?

Step-by-step explanation:

there are 2 main approaches (in their core they are the same, of course, but they look different) :

1. use one equation to express one variable by the second, and then use this in the second equation to solve for the remaining variable. with that you go back into the first equation and solve for the first variable.

2. multiply both equations by certain factors as needed, then add both results, so that there is one summary equation with only one variable, and then solve for it. then use that in one of the original equations and solve for the second variable.

using 1.

3x + 2y = 1

3x = 1 - 2y

x = (1 - 2y)/3

2x + 7y = 3

2(1 - 2y)/3 + 7y = 3

2(1 - 2y) + 21y = 9

2 - 4y + 21y = 9

17y = 7

y = 7/17

x = (1 - 2y)/3 = (1 - 2×7/17)/3 = (1 - 14/17)/3 =

= (17/17 - 14/17)/3 = 3/17 / 3 = 1/17

using 2.

multiply first equation by 2, the second by -3

6x + 4y = 2

-6x - 21y = -9

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

0 -17y = -7

-17y = -7

17y = 7

y = 7/17

and so on (as under 1.).

Answer:

As Per Provided Information

Diameter of Garden 12 yards

Radius of Garden will be 12/2

Radius of Garden will be 6 cm

We have been asked to find the area of the circular garden .

Formula Used here

$\underline{\boxed {\bf \: Area_{(Garden)} \: = \pi {r}^{2}}}$

Just put the value and let's calculate the area of circular garden .

$\qquad \longrightarrow\sf \: Area_{(Garden)} \: = 3.14 \times {6}^{2} \\ \\ \\ \qquad \longrightarrow\sf \: Area_{(Garden)} \: = 3.14 \times 36 \\ \\ \\ \qquad \longrightarrow\sf \: Area_{(Garden)} \: = 113.04 \: {yard}^{2}$
