I'm pretty sure it would be 2 and 90, let me know if I'm wrong.
Answer:
2, 90
Step-by-step explanation:
Divide 54 by 3 to get how many licks are needed for ONE lollipop. Once you figure how many licks are needed for ONE, you can figure out how many it takes for any amount of lollipops.
54 licks / 3 lollipops = 18 licks / 1 lollipop
Divide 36 by 18 and multiply the quotient by 18 to find the number of lollipops 36 licks takes.
36 licks / 18 licks = 2 lollipops (this is your first answer)
Now multiply 18 by 5 like so: 18 * 5 = 90 (this is your second answer)

Step-by-step explanation:
To find the value of x, you have to square both sides of the equation. [tex]\sqrt{x^{2} }[/tex] cancels out to just [tex]x[/tex], so you're left with [tex]x=[/tex]±[tex]\sqrt{10}[/tex].

I needdd helpppppp what is m<2+m<3?
In triangle ABC:
∠1 = 90°
According to the angle sum property:
∠1 + ∠2 + ∠3 = 180
Since angle 1 is 90 degrees
∠2 + ∠3 = 180 - 90
∠2 + ∠3 = 90° [∠1 + ∠2 + ∠3 = 180]
What is the image of (-7,-6) after a dilation by a scale factor of 1/2 centered at the origin
Answer:
(-3.5, -3).
Step-by-step explanation:
That would be (-7/2, -6/2) or (-3.5, -3)..
Answer:
(-7/2, -3)
Step-by-step explanation:
When the center of the dilation is the origin, each coordinate value is multiplied by the dilation factor.
The image point is ...
(1/2)(-7, -6) = (-7/2, -3)
Determine what must be multiplied so that the expression below will have a common denominator. Use the backslash / to type in a fraction.
Answer:
Multiply the first fraction by [tex]\frac{x+4}{x+4}[/tex]
Multiply the second fraction by [tex]\frac{x-4}{x-4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4}{x^2 - 16} + \frac{3}{x^2 + 8x + 16}[/tex]
Required
Make the denominator equal
[tex]\frac{4}{x^2 - 16} + \frac{3}{x^2 + 8x + 16}[/tex]
Factorize the denominator
[tex]\frac{4}{x^2 - 4^2} + \frac{3}{x^2 + 4x + 4x+ 16}[/tex]
[tex]\frac{4}{(x - 4)(x + 4)} + \frac{3}{(x+ 4)(x + 4)}[/tex]
Multiply the first fraction by [tex]\frac{x+4}{x+4}[/tex]
Multiply the second fraction by [tex]\frac{x-4}{x-4}[/tex]
[tex]\frac{x+4}{x+4} * \frac{4}{(x - 4)(x + 4)} + \frac{3}{(x+ 4)(x + 4)} * \frac{x-4}{x-4}[/tex]
[tex]\frac{4(x + 4)}{(x - 4)(x + 4)(x + 4)} + \frac{3(x - 4)}{(x+ 4)(x + 4)(x - 4))}[/tex]
[tex]\frac{4(x + 4)}{(x^2 - 16)(x + 4)} + \frac{3(x - 4)}{(x^2 - 16)(x + 4))}[/tex]
The expression now have the same denominator

A jazz band wants to sell $24,000 worth of tickets. If each ticket costs $80, how many tickets will the band have to sell to meet its goal?
Answer:
300
Step-by-step explanation:
24000/80
Answer:
300
Step-by-step explanation:
you have to sell $24000 worth of tickets and each is $80, so you do 24000/80 which you get 300 so you have to sell 300 more to meet its goal. since one ticket is 80 dollars then you divide 24000 with 80 so you get how many more tickets need to be sold. If you check your answer 300 tickets and each is $80 you do 300x80 which gives you $24000.
