Answer:

x=5

Step-by-step explanation:

So first we want to find x by itself, so we can subtract 4 from both sides:

x=5

That is your simple answer!

Step-by-step explanation:

$\huge{ \sf{x + 4 = 9}}$

~ Move 4 to right hand side and change it's sign :

⟼ $\huge{ \sf{x = 9 - 4}}$

~ Subtract 4 from 9

⟼ $\huge{ \sf{x = 5}}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \bold{ \text{5}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ツ

Divide 20 chocolates between Adi and Suresh such that adi gets 60% while Suresh gets 40% of the chocolates

Eddi Din [679]

Hello!

To find how much chocolate Adi and Suresh receives, you need to convert the percentage to a decimal, then you multiply that decimal by the total number of chocolates, which is 20.

To convert percentages to decimals, divide the percentage by 100, and remove the percentage.

60% / 100 = 0.60

20% / 100 = 0.20

Then, we multiply 0.60 and 0.20 by 20.

0.60 x 20 = 12

0.40 x 20 = 8

Therefore, Adi gets 12 chocolates and Suresh gets 8 chocolates.

Enter an inequality that represents the graph in the box.

ANTONII [103]

The inequality that represents the graph in the box is

$y>-3x+6$

Given :

The graph of the linear inequality

Lets pick two points from the graph to frame the linear equation

Slope intercept form of the equation is

$y=mx+b$

Where m is the slope and b is the y intercept

y intercept is (0,6) from the graph

so b=6

Now we find out slope m using formula

Pick two points (0,6) and (2,0)

$slope = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-6}{2-0} =-3$

m=-3

So the equation is $y=-3x+6$

Now we check the inequality sign by testing any point on shaded area

lets pick (4,0)

lets plug in 4 for x and 0 for y

$y=-3x+6\\0=-3(4)+6\\\\0=-6\\0>-6$

The inequality for the given graph is

$y>-3x+6$

we cannot use >= sign because we have dotted lines

Ten percent of 640 is what number?

Lelechka [254]

Ten percent of 640 is 64.

640/100=6.4

6.4*10=64.

There are many other ways to find this but that is the way I have always used :)

Hope this helps!

How to do factor each expression 63 + 81

Katyanochek1 [597]

Answer:

$9(7 + 9)$

Step-by-step explanation:

To factor an expression you have to first find the highest common factor (HCF) of the numbers in the expression. You divide them by their HCF, bracket it and place the HCF outside the bracket.

$63 + 81 = \\ 9(\frac{63}{9} + \frac{81}{9}) = \\ 9(7 + 9)$

To check if it is factored properly you can do the opposite of what you just did by clearing the bracket.

9 (7 + 9)

(9 x 7) + (9 x 9)

= 63 + 81
