Can you please help me?
Answer:
1 = 3
2 = 6
3 = 9
Step-by-step explanation:
for every # it is multiplied by 3 (ex. 7 • 3 = 21, 8 • 3 = 24, ect.)
therefore if it is multiplied by 3 each time
then 1 • 3 = 3
2 • 3 = 6
and 3 • 3 = 9
hope this helps :)

Use properties of equality to isolate y.
x + y = 10
y = ?
Answer:
x+y=10
y=10-x
To isolate y, you subtract x on both sides.

What is the area, in square meters, of the shaded region in the diagram?
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Algebra please solve 7(2x - 3y) + 4(3y - 5x) =
Answer:
-8x-9y
Step-by-step explanation:
Hey There!
So basically this problem is asking you to simplify this expression using distributive property
The first step would be to distribute 7 into what is inside the parenthesis (2x and -3y)
2x*7=14x
-3y*7=-21y
so now we have 14x-21y + 4(3y-5x)
the next step would be to distribute 4 to what is inside the parenthesis (3y and -5x)
4*3y=12y
4*-5x=-20x
so now we have 12x-21y-20x+12y
the final step is to combine like terms
12x-20x=-8x
-21y+12y=-9y
so the simplified version of 7(2x - 3y) + 4(3y - 5x) is -8x-9y
Answer:
14x-21y+12y-20x. 14x-20x+12y-21y. -6x-9y
A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole number?
The population of the town after 5 years will be 147089 (approx).
Step-by-step explanation:
The exponential growth equation is given by :-
f(x)=A(1+r)^x...(*)
, where A = initial population , r= rate of growth ( in decimal) and x is time.
As per given , we have
A= 13000
r=2.5%=0.025
x= 5 years
Using (*), the population of the town after 5 years would be :
f(5)=13000(1+0.025)^5=13000(1.025)^5\\\\=13000(1.13140821289)=14708.306767614708.3067676\approx147089
Hence, the population of the town after 5 years will be 147089 (approx).

Answer:
392
Step-by-step explanation:
Answer:
Final answer: x=0 m:3 and x=-6 m:2
Step-by-step explanation:
1. 4x³(x²+12x+36)- Divide by greatest common factor, to simplify.
2. 4x³(x+6)(x+6)- Factored
3. 4x³ = 0 Set each factor equal to zero
4. x+6=0 x+6=0
So, x= -6, two times, mulitiplicity 2
So, 4x³=0, so x=0 three times, mulitiplicity 3
Final answer: x=0 m:3 and x=-6 m:2

What is m
А
105°
86°
C
E
137°
D
Answer:
122 degrees
Step-by-step explanation:
*A pentagon has a total of 540degrees
1st step: take all of the degrees and add them up:
105 + 90 + 86 + 137 = 418
2nd step: subtract the sum from 540:
540 - 418 = 122
The missing angle is 122 degrees
Answer:
∠ C = 122°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540°
∠ C + 137° + 86° + 105° + 90° = 540 , that is
∠ C + 418° = 540° ( subtract 418° from both sides )
∠ C = 122°

Stacey works at the park 5 months out of the year. What percent of the year does she work? Round to the nearest hundredth.
help meee
what is the mistake?
x-5=17+5
x=22
choose one:
- unknown value isn't 22
-work is not shown on both sides
-wrong inverse operation is used
-17+5 is not 22.
Answer:
x = 17+5-5
x=17
so this equation is wrong
Which Of the following area models correctly describes the algebraic expression
x^2 + 2x + 3?
Answer:
C
Step-by-step explanation:
Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Answer:
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Step-by-step explanation:
Rounding to the nearest hundred means rounding 271 to 300 and 550 to 600.
Think of it as
271 changes to 0.271
The 7 would be in the hundredths place.
7 is greater than 5; therefore, round up.
Now you have 0.3, change this back to it's normal decimal places to get 300.
550 changes to 0.550
Where the second 5 would be in the hundredths place.
5 is equal to 5; therefore, round up.
Now you have 0.6, change this back to it's normal decimal places to get 600.
Mark rounded to the nearest place which is not the same.

Solve for the variable
Answer:
40
Step-by-step explanation:
Try to get the variable alone by dividing 5/8 on both sides of the equations.
That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.
Answer:
40
Step-by-step explanation:
Multiply both sides by 8/5

Step-by-step explanation:
covert this repeating decimal into a fraction
Answer: 4311/9900 or 479/1100
Step-by-step explanation:
Okie so in order to do this, we need to get rid of the repeating part of the decimal
==============================================================
Right now we have x = 0.435454545454...
If we multiply this by 100, we get
100x = 43.545454545454
And if we multiply by 10000 we get
10000x = 4354.5454545454
==============================================================
Subtract the two equations
10000x = 4354.5454545454
100x = 43.545454545454
------------------------------------------------- (notice: the repeating part will cancel out)
9900x = 4311
x = 4311/9900
If you simplify the fraction you get: 479/1100
The fraction that represents the repeating decimal is
[tex]\frac{479}{1100}[/tex]
Given :
A repeating decimal [tex]0.4354545454...............[/tex]
there is bar at 54 , so 54 is repeating
We need to convert this decimal into fraction
54 is repeating so we multiply by 100
Let x= [tex]0.4354545454...............\\[/tex]
[tex]100x=43.54545454...............[/tex]
Now we subtract x from 100x
[tex]100x=43.54545454...............\\ x= 0.4354545454...............\\-----------------------------------------\\ 99x=43.11[/tex]
Now divide both side by 99
[tex]x=\frac{43.11}{99} \\[/tex]
multiply top and bottom by 100 to remove the decimal
[tex]x=\frac{4311}{9900} \\Divide \; top \; and \; bottom \; by 9\\x=\frac{479}{1100}[/tex]
