rewrite 2 x 2^4 as an expression as a single power
If you're wanting it alone just with the exponents, here is how you're going to do it:
Technically, the 2 alone has a power, and it's simply just one. When exponents are being used in numbers multiplying together, they add.
So, to simplify this it'd be 2^5.
If you're wanting the actual answer, you would do exponents first. Remember that exponents are just the number being multiplied by itself x times:
2 x 2 x 2 x 2 = 16
Now we just need to multiply this by 2 and you'll get 32.
OR, if you do the 2^5, you'll still get 32!

Answer:
81/x - 3 = 6 2x - 3 = 15Answer:
it's only the last two
Step-by-step explanation:
3x + 2 = 25
3x + 2 - 2 = 3x
25 - 2 = 23
3x = 23
3x / 3 = x
23 / 3 = 7 2/3
x = 7 2/3 not this one
x/3 + 7 = 8
x/3 + 7 - 7 = x/3
8 - 7 = 1
x/3 = 1
x/3 * 3 = x
1 * 3 = 3
x = 3 not this one
4 + 5x = 18
4 + 5x - 4 = 5x
18 - 4 = 14
5x = 14
5x / 5 = x
14 / 5 = 2 4/5 not this one
24 - 2x = 13
24 - 2x - 24 = -2x
13 - 24 = -11
-2x = -11
-2x / -2 = x
-11 / -2 = 5 1/2 not this one
81/x - 3 = 6
81x - 3 + 3 = 81/x
6 + 3 = 9
81/x = 9
81/x * x = 81
9 * x = 9x
81 = 9x
81 / 9 = 9
9x / 9 = x
9 = x this one
2x - 3 = 15
2x - 3 + 3 = 2x
15 + 3 = 18
2x = 18
2x / 2 = x
18 / 2 = 9
x = 9 this one

Solve the following inequality for y.
18x + 6y > 12
Answer:
12
Step-by-step explanation:
Simplifying
18x + -6y = 12
Solving
18x + -6y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
18x + -6y + 6y = 12 + 6y
Combine like terms: -6y + 6y = 0
18x + 0 = 12 + 6y
18x = 12 + 6y
Divide each side by '18'.
x = 0.6666666667 + 0.3333333333y
Simplifying
x = 0.6666666667 + 0.3333333333y

Martin is an artist who molds plaster into unique shapes. How much plaster can Martin fit into the mold shown? Cuboid with length as 1 ft, height as 2 ft and width as 1 ft. Is placed above the cuboid with length, height and width as 4 ft. A. 66 ft3 B. 80 ft3 C. 128 ft3 D. 256 ft3
Answer:
[tex]Amount = 66ft^3[/tex]
Step-by-step explanation:
No attachment given, but the question can still be solved.
Given
Cuboid 1
[tex]Length = 1ft[/tex] [tex]Width = 1ft[/tex] [tex]Height = 2ft[/tex]
Cuboid 2
[tex]Length = Width = Height = 4ft[/tex]
Required
How much plaster can fit in
To do this, we simply calculate the volume of the shape
For cuboid 1
[tex]Volume = Length * Width * Height[/tex]
[tex]V_1 = 1 * 1 * 2[/tex]
[tex]V_1 = 2ft^3[/tex]
For cuboid 2
[tex]V_2 = 4 * 4 * 4[/tex]
[tex]V_2 = 64ft^3[/tex]
Amount of plaster is then calculated as:
[tex]Amount = V_1 + V_2[/tex]
[tex]Amount = 2ft^3 + 64ft^3[/tex]
[tex]Amount = 66ft^3[/tex]
A recipe calls for 2 cups sugar to 3 cups flour. How many cups of sugar is needed for 9
cups of flour?
a.
6 cups
b. 4 cups
c. 5 cups
d 7 cups
Answer:
a) 6 cups
Step-by-step explanation:
We can use a ratio for this:
sugar : flour
2 : 3
x : 9
2 3
--- = ---
x 9
Cross multiply:
2 (9) = 3x
18 = 3x
6 = x
x = 6
To double-check, you can plug the value back into the ratio and make them fractions, then simplify to see if it gets the original amount. Here's what I'm talking about:
2 : 3
x : 9 ======> 6 : 9
[tex]\frac{6}{9} \frac{/3}{/3} = \frac{2}{3}[/tex]

Answer:
x = 12 and y = 31
Step-by-step explanation:
Hey There!
So the two angles with x are interior angles meaning that they are congruent
So to solve for x we use the equation
3x+17=5x-7
step 1
add 7 to each side
17+7=24
-7+7 cancels out
now we have
3x+24=5x
step 2 subtract each side by 3x
3x-3x cancels out
5x-3x=2x
were left with
2x=24
final step divide each side by 2
24/2=12
2/2 cancels out
x=12
now we plug it into one of the expressions
3x12=36
36+17=53
the angle that is equal to 53 is supplementary to the angle with y meaning that they add up to 180
so to solve for y we use this equation
180=4y+3+53
step 1 combine like terms
53+3=56
now we have
180=4y+56
step 2 subtract each side by 56
180-56=124
124=4y
step 3 divide each side by 4
124/4=31
y=31
so we can conclude that
x=12 and y = 31
