HEY GUYS PLEASE HELP ME I WILL MARK WHOEVER EXPLAINS IT WELL AS BRAINLIEST .!! -3X+3Y=24X+2Y=13
REMEMBER I AM SOLVING FOR BOTH X AND Y ASAP I DO NOT HAVE TIME

Answers

Answer 1
Answer: -3x + 3y = 24
x + 2y = 13

(x + 2y) - 2y = 13 - 2y
x = 13 - 2y

-3(13 - 2y) + 3y = 24
-39 + 6y + 3y = 24
9y - 39 = 24
(9y - 39) + 39 = 24 + 39
9y = 63
9y ÷ 9 = 63 ÷ 9
y = 7

x + 2y = 13
x + 2(7) = 13
x + 14 = 13
(x + 14) - 14 = 13 - 14
x = -1

When x = -1
y = 7


An easy way to check: 
-3x + 3y = 24
-3(-1) + 3(7) = 24
3 + 21 = 24
24 = 24

Since it is the same on both sides, our answers are correct.

At present Asha's age (in years) is two more than the square of her daughter Nisha's age (in years). When Nisha grows to her mother's present age, Asha's age would be one year less than 10 times the present age of Nisha. Find the present age of Asha and Nisha

Answers

Answer:

Asha's present age is 27 years and Nisha's present age is 5 years.

Step-by-step explanation:

Let the present age of Nisha be x years.

As per question, Asha's present age is 2 more than the square of Nisha's age.

\thereforeAsha's present age =x^2+2

Now, Nisha will reach her mother's age after x^2+2-x years.

Therefore, age of Asha after x^2+2-x years will be = x^2+2+x^2+2-x=2x^2-x+4

Now, as per question,

2x^2-x+4=10x-1\n2x^2-x-10x+4+1=0\n2x^2-11x+5=0\n2x^2-x-10x+5=0\nx(2x-1)-5(2x-1)=0\n(2x-1)(x-5)=0\nx=(1)/(2)\ or\ x=5

As age can't be in fraction, we consider the present age of Nisha as 5 years. So, Asha's present age is x^2+2=5^2+2=25+2=27 years.

Therefore, Asha's present age is 27 years and Nisha's present age is 5 years.

How do I draw and shade a figure that represents 100% 100% and describe it in words ?

Answers

Answer:

The required shaded figure is shown in Figure 2:

Step-by-step explanation:

Consider the provided statement.

You need to draw a figure and need to shade 100%

Let us first draw a figure of circle as shown in Figure 1:

Remember: You can draw any figure or shape for example: square, rectangle, triangle etc.

Now, it is given that we need to shade the figure that represents 100%.

100% of a figure is also know as the whole figure.

Thus, shade the whole figure. Where you can use any color in order to shade.

The required shaded figure is shown in Figure 2:

Draw anything and color the whole thing in. And should be described as "one whole" in words.

Hope this helps

2x=(360/4) solve for x please

Answers

If 2x=(360/4)  then the The value of x is 45.

To solve for x, we can simplify the equation step by step:

Step 1: Simplify the right side of the equation:

360/4 = 90

Step 2: Substitute the value of (360/4) into the equation:

2x = 90

Step 3: Isolate x by dividing both sides of the equation by 2:

x = 90/2

x = 45

So, the value of x is 45.

Hi there! First, we have to simplify both sides of the equation, 2x=360/4=2x=90. Now, we divide both sides by 2, 2x/2=90/2, 90/2=45. Therefore, the answer is x=45.

Explain how to use partial quotients to divide 235 by 5

Answers

The solution to the division problem using partial quotients is 47

Given the division problem expressed as (235)/(5)

We are to divide the expression using the partial quotient as shown below:

= (235)/(5) \n= (200)/(5) + (35)/(5)

Find the quotient of the individual term to have;

=(200)/(5) +(35)/(5) \n=40 + 7\n= 47

Hence the solution to the division problem using partial quotients is 47

Answer: 235 divided by 5 = 47


Step-by-step explanation:(with reference to the figure)

To find  235 divided by 5 by partial quotients .

Here dividend= 235 and divisor =5

Step 1: Write easy multiples of divisor that is nearest to the dividend as follows

5×10=50

5×20=100

5×30=150

5×40=200(nearest easy factor)

Step 2: Now subtract 200 from 235 ,we get 35 then subtract 35=5×7 from it we get 0.

Step 3: Adding the factors we have used in step 1 and 2 ,it will give required quotient=40+7=47

i.e. 235=5(40)+5(7)
