Answer:
c) 9x and 8x
Step-by-step explanation:
3x + 8 + 3y + 8x
the like terms are 3x and 8x since they both have the same variables
8 and 3y are not the like terms because there's no other number with the same variable as them.
A square 10cm on each side has four quarter circles drawn with centers at the four corners. How many square centimeters are in the area of the shaded region? Express your answer in terms of $\pi$.
Answer:The answer is 100-25pi
Step-by-step explanation:
quarter circles = full circle
Full circle area = pie r2
Square area = s2
In this case, the side of the square is twice the radius of the circle
What is the radius of a circle with circumference of 50 cm? Round your answer to the nearest whole number. Use π = 3.14.
A. 4 cm
B. 3 cm
C. 8 cm
D. 7 cm
Answer:
8 is the answer
Step-by-step explanation:
the equation is r = C/2*3.14
2*3.14=6.28
Because your C is 50 you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.
evaluate the expression if g+2, r+3, and t=11.
g+6t
Answer:
I think you copied this wrong
Step-by-step explanation:
Most likely g = 2
Therefore (2) + 6(11)
2+66=68
A car requires 45 liters of petrol to travel a distance of 330 km.
1) the distance that the car can travel on 85 liters of petrol
2) the amount of petrol that the car owner has to pay to travel a distance of 990km if a liter of petrol costs $ 2.25.
Answer:
1) The car can travel 623.3 km with 85 liters of petrol.
2) The car owner has to pay $303.8.
Step-by-step explanation:
1) The distance traveled with 85 L of petrol can be found as follows:
[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]
Hence, the car can travel around 623 km with 85 liters of petrol.
2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:
[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]
Therefore, the car owner has to pay $303.8.
I hope it helps you!
a equivalent or odd number between 90 and 180
Answer:
That means from 80 to 90, there are 5 odd numbers.
That also means, in between 10 numbers, there are 5 odd numbers.
It's fair enough to believe now that in the next 20 numbers—80 to 100—there will be 10 odd numbers.
Another pattern.
And the conclusion: from 80 to 180, there are 100 numbers. Therefore, There Will Be 50 Odd Numbers.
There are 50 odd numbers between 80 and 180.
Step-by-step explanation:
Answer:
An odd number between 90 and 180 is 91
can I please get help?!
Answer:
The answer is d.
Step-by-step explanation:
x is "a number." When a variable and a number are next to each other, they are being multiplied. So it's 7 times a number. Then you take the product of that and add 2.
So, d is the correct answer. :D

In square ABCD, AC = 6x + 10, and BD = 10x + 2. What is the length of AC?
Hint: Diagonals are congruent, hence AC = BD
A)11
B)22
C)3.5
D)2
Answer:
B) 22
Step-by-step explanation:
AC = BD
6x+10 = 10x+2
simplify:
subtract 6x and 2 from both sides:
4x = 8
x = 2
then:
AC = 6(2)+10 = 22
find the length of the missing side
Answer:
x = 11.1

HELPPPPPPPPPP PLEASEEEEEEEEEEEEE !!!!!
Answer:
218.665
Step-by-step explanation:
Separate by shape, find the areas of the triangles first, so (10.1 x w)/2 To get the missing side you do 30.5-21.4=9.1. then divide that by 2 because you have 2 lines (triangles) that aren't part of the 21.4. After you find the area for the one triangle (10.1 x 4.55)/2=22.9775, multiply by 2 to get the combined area of both triangles. Next step is to find the area of the rectangle, which is just 21.4 x 30.5=216.14. Add all the areas, 45.955+216.14=262.095. Last step is to subtract the area of the shaded region, the rhombus, which is just diagonal x diagonal / 2. so (8.6 x 10.1)/2=43.43. 262.095-43.43=218.665.

Lisa is planning for a party. She receives quotes from two party planners. Choice A quotes $18 per guest, plus $100 for renting the party hall. Choice B quotes $15 per guest, plus $160 for renting the party hall. Which inequality represents the number of guests Lisa can invite, if choice A were to cost less than choice B?
Answer:
x<20
Step-by-step explanation:
Building linear functions for each situation, the inequality is:
[tex]18x + 100 < 15x + 160[/tex]
------------------
Choice A:
$18 per guest.$100 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_a(x) = 18x + 100[/tex]
Choice B:
$15 per guest.$160 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_b(x) = 15x + 160[/tex]
A cost less than B, thus, the inequality is:
[tex]C_a(x) < C_b(x)[/tex]
[tex]18x + 100 < 15x + 160[/tex]

Express [tex]\frac{x}{x+2} +\frac{2x}{x-4}[/tex]as a single fraction in its simplest form.
Answer:
[tex]\frac{3x^2}{(x+2)(x-4)}[/tex]
Step-by-step explanation:
Before adding the fractions we require them to have a common denominator.
Multiply numerator/ denominator of first fraction by x - 4
Multiply numerator/ denominator of second fraction by x + 2
= [tex]\frac{x(x-4)}{(x+2)(x-4)}[/tex] + [tex]\frac{2x(x+2)}{(x+2)(x-4)}[/tex] ← expand and simplify numerators, leaving common denominator
= [tex]\frac{x^2-4x+2x^2+4x}{(x+2)(x-4)}[/tex]
= [tex]\frac{3x^2}{(x+2)(x-4)}[/tex]

Answer:
Step-by-step explanation:
1). 3x(2x - 2) = 3x(2x) + 3x(-2) [By distributive property]
2). x²(_ + 5x - 3) = (3)x² + x²(5x) + x²(-3)
3). _(x² - 3x + _) = x(x²) - (x)(-3x) + (x)(2)
4). (2x + 9)(x + 2) = 2x(x + 2) + 9(x + 2)
= 2x² + 4x + 9x + 18
= 2x² + 13x + 18
5). (z - 4)(2z + 1) = z(2z + 1) + (-4)(2z + 1)
= 2z² + z - 8z - 4
= 2z² - 7z - 4
