select all expressions that are equal to 3•3•3•3•3
B and C are correct
Answer:
B and C
Step-by-step explanation:
3*3*3*3*3 is the same as 3 to the 5th power since there are 5 threes. And then if you put 3 to the 4th power multiplied by 3 into a calculator, you'll get the same answer.
I need help can y’all please help me

Is this a function?
-4x - 6x = -20 =?
-3(2x - 3) = 33 = ?
4x + 3x + 2x = 180 = ?
Answer:
-4x-6x=-20=
x=2
-3(2x-3)=33=
x=-4
4x+3x+2x=180
x=20
Step-by-step explanation:
-4x-6x=-20
-4+(-6)=-10x
-10x=20 (divide both by 10)
x=-2 (divide by -1 to get positive)
x=2
-3(2x-3)=33
-6x+9=33
-9 . -9
-6x=24 (divide both by -6)
x=-4 (divide by -1 to make positive)
4x+3x+2x=180
(combine like terms)
9x=180 (divide both sides by 9)
x=20
How do I find x in this problem?
Answer:
(6-2)×180 = 720
101+154+72+123+145+x=720
595 + x = 720
x = 720-595
x= 125
I don't remember how to solve this problem I missed yesterday when we learned it. 4(x-2+y)

4(x - 2 + y)
4x - 8 + 4y
You multiply each term in the parenthesis by the number in front of it.
Pleasee helpp answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!
Answer:
x = 132º
Step-by-step explanation:
the sum of two angles on the same side is 180º so...
x + 48º = 180º subtract 48º from both sides
x = 132º

does 9/20 and 18/30 form a proportion
Answer:
No, they don't.
Step-by-step explanation:
I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.
18 ÷ 9 = 2
30 ÷ 20 = 1.5
The quotients aren't the same. Same thing if you convert the fractions to decimals:
9 ÷ 20 = 0.45
18 ÷ 30 = 0.6
This means the two values do NOT form a proportion.
Hope this helps! Have a great day!
Answer:
No.
Step-by-step explanation:
9/20=18/30
9*30=20*18
120=360

Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?
Answer:
14
Step-by-step explanation:
7.5x + 25 = 130
-25 -25
7.5x = 105
[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]
x = 14
Hence, she must make 14 visits in order to earn a free movie ticket.

Step-by-step explanation:
A cone has volume 3. If the cone's radius is 1. what is its height?
2.87 units
The volume of a cone is found by using the formula, V = (1/3)(pi)(h)r^2
Substituting values:
3 = (1/3)(3.14)(h)(1)
2.87 = h

15 * 1 centimeter = 15 cm
Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

Step-by-step explanation:
write the equation of the line
Answer:
y = (3/-2)x + 4.
Step-by-step explanation:
slope intercept form is y = mx + b
1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.
2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).
3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.
