Answer:
C. x = 8
Step-by-step explanation:
We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.
Let's multiply 6 x 6 x 6.
36 x 6 = 216.
Let's multiply 8 x 8 x 8.
64 x 8 = 512
The answer would be C. x = 8.
I hope that this helps! :)
Answer:
8
Step-by-step explanation:
x³ = 512
x³ = 8³
Cube root on both sides,
x = 8
Simplify this expression.

3 + 2p - 4 = 11
algebra 1 solving equations
Answer: the variable is p=6 .
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
p = 6
Step-by-step explanation:
Step 1: Simplify both sides.
3 + 2p − 4 = 11
3 + 2p + −4 = 11
(2p) + (3+−4) = 11 (Combine Like Terms)
2p + −1 = 11
2p − 1 = 11
Step 2: Add 1 to both sides.
2p − 1 + 1 = 11 + 1
2p = 12
Step 3: Divide both sides by 2.
2p/2 = 12/2
p=6

. A person weighing 120 pounds has about 20 pints of blood in their body. Which equation below represents the relationship between pints of blood, b, to a person's weight, w?
Answer:
[tex]w = 6b[/tex]
Step-by-step explanation:
Given
[tex]b = blood[/tex]
[tex]w = weight[/tex]
[tex]b = 20; when\ w = 120[/tex]
Required
Determine the equation that binds both parameters
First, we need to determine the constant of proportionality using:
[tex]w = k * b[/tex]
Where k represents the constant.
Substitute 120 for w and 20 for b
[tex]120 = k * 20[/tex]
Divide both sides by 20
[tex]6 = k[/tex]
[tex]k = 6[/tex]
Using the same formula, substitute 6 for k
[tex]w = 6 * b[/tex]
[tex]w = 6b[/tex]
Hence:
The equation is represented as [tex]w = 6b[/tex]
The quotient below is shown without the decimal point. Use number sense to place the decimal point correctly.
340.1 ÷ 9.5 = 358
Answer:
35.8
Step-by-step explanation:
[tex]\frac{340.1}{9.5}[/tex] = 358
We know that our answer can never be greater than 358 since the dividend
is 340.1 and the divisor is 9.5;
Also,
Both values are to one decimal places and we can use this to solve the problem;
9 can divide 340 in about 37 place with a remainder of 7,
So, it is appropriate to make the solution 35.8

What is 708 divided by 67 with a remainder?
Answer:
its 10 with the remainder of 38
Step-by-step explanation:
The result of the division is remainder = 38 and quotient = 10
What is division?Division is the opposite of multiplying. When we know a multiplication fact, we can find a division fact: Example: 3 × 5 = 15, so 15 / 5 = 3. Also, 15 / 3 = 5.
Given that, 708 divided by 67
When dividing 708 by 67 will get 10 as quotient and 38 remainder
Hence, the result of the division is remainder = 38 and quotient = 10

If △EFG ≅ △HJK, complete each part.
Answer:
[tex] \overline{EG} \cong \overline{HK} [/tex]
[tex] \overline{HJ} \cong \overline{EF} [/tex]
[tex] \angle F \cong \angle J [/tex]
[tex] \angle H \cong \angle E [/tex]
∆FGE ≅ ∆JKH
Step-by-step explanation:
Since ∆EFG ≅ ∆HJK, therefore, the corresponding sides and angles of both ∆s are congruent.
Thus:
[tex] \overline{EG} \cong \overline{HK} [/tex]
[tex] \overline{HJ} \cong \overline{EF} [/tex]
[tex] \angle F \cong \angle J [/tex]
[tex] \angle H \cong \angle E [/tex]
∆FGE ≅ ∆JKH (take note of the arrangement of the letters or naming of each vertex of both triangles. Each vertex of in one ∆ must correspond to the vertex of the other for the ∆s to be congruent)
△EFG ≅ △HJK,
From the figure attached we can conclude that
[tex]\rm \bar {EG}[/tex] ≅ [tex]\rm \bar {HK}[/tex]
[tex]\rm \bar HJ[/tex] ≅ [tex]\rm \bar FE[/tex]
∠[tex]\rm F[/tex] ≅∠[tex]\rm J[/tex]
∠[tex]\rm H[/tex] ≅∠[tex]\rm E[/tex]
△FGE ≅ △JKH
Given that
△EFG ≅ △HJK,
Since △EFG ≅ △HJK is given hence we can conclude that corresponding sides and corresponding angles of both the triangles will be equal.
Two triangles are said to be congruent when they are of similar shape and size means all the angles of one triangle are equal to the corresponding angles of other triangle and all the sides of one triangle are equal to corresponding sides of other triangle.
From the figure attached we can conclude that
[tex]\rm \bar {EG}[/tex] ≅ [tex]\rm \bar {HK}[/tex]
[tex]\rm \bar HJ[/tex] ≅ [tex]\rm \bar FE[/tex]
∠[tex]\rm F[/tex] ≅∠[tex]\rm J[/tex]

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

A. 1
B. 6
C. 13
D. 17
The value of x is 13 if lines m and n are parallel and lines m and n are cut by transversal p.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
As we can see in the figure, the lines m and n are cut by transversal p.
Then the sum of angles mZ1 and mZ2 is equal to 180 degree.
4x + 14 +8x + 10 = 180
12x + 24 = 180
12x = 156
x = 13
Thus, the value of x is 13 if lines m and n are parallel and lines m and n are cut by transversal p.
