Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4

1. a. A cube’s volume is 512 cubic units. What is the length of its edge?
b. If a sphere fits snugly inside this cube, what is its volume?
c. What fraction of the cube is taken up by the sphere? What percentage is
this? Explain or show your reasoning.
Answers
Answer:
a) The length of its edge is 8 units.
b) The volume of the sphere is approximately 268.083 cubic units.
c) The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.
Step-by-step explanation:
a) The volume of a cube ([tex]V_{c}[/tex]), measured in cubic units, is defined by the following expression:
[tex]V_{c} = L^{3}[/tex] (1)
Where [tex]L[/tex] is the side length of the cube, measured in units.
If we know that [tex]V_{c} = 512\,u^{3}[/tex], then the length of its edge is:
[tex]L = \sqrt[3]{V_{c}}[/tex]
[tex]L = 8\,u[/tex]
The length of its edge is 8 units.
b) The volume of a sphere ([tex]V_{s}[/tex]), measured in cubic units, that fits snugly inside this cube is defined by:
[tex]V_{s} = \frac{\pi}{6}\cdot L^{3}[/tex] (2)
If we know that [tex]L = 8\,u[/tex], then the volume of the sphere is:
[tex]V_{s} \approx 268.083\,u^{3}[/tex]
The volume of the sphere is approximately 268.083 cubic units.
c) The fraction of the cube taken by the sphere is the ratio of the volume of the sphere to the volume of the cube. That is to say:
[tex]r = \frac{V_{s}}{V_{c}}[/tex]
If we know that [tex]V_{c} = 512\,u^{3}[/tex] and [tex]V_{s} \approx 268.083\,u^{3}[/tex], then the fraction of the cube that is taken up by the sphere is:
[tex]r = 0.524[/tex]
The result in percentage form is calculated by multiplying the result above by 100.
[tex]\% r = 52.4\,\%[/tex]
The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.

so basically you’re not changing the group ( associative ) and you’re not multiplying into the groups ( Distribuative ) so the only other option would be Commutative, and you’re changing the order of the numbers so it would be commutative.

Answer:
Angle A measures 76°
Step-by-step explanation:
The three interior angles of a triangle will always equal 180. Therefore:
[tex](63)+(x+7)+(2x+8)=180[/tex]
Solve for x. Add and combine like terms:
[tex]78+3x=180[/tex]
Subtract 78 from both sides:
[tex]3x=102[/tex]
Divide both sides by 3. So, the value of x is:
[tex]x=34[/tex]
Angle A is given by:
[tex]m\angle A=2x+8[/tex]
Since we know that x = 38:
[tex]m\angle A=2(34)+8=76[/tex]
Angle A measures 76°

Answers
Answer:
72
Step-by-step explanation:
The pythagorean theorem states that in a right triangle A^2 + B^2 = C^2 where A and B are the two smaller sides and C is the hypotenuse.
Because of this, in this triangle 30^2 + B^2 = 78^2
Which means B^2 = 5184
And B = 72

What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
A mapping diagram is used to illustrate the relationship between sets of domains and ranges.

From the mapping diagram,
Each arrow represents the ordered pairs,
So,
The ordered pair is given as,
(0,4), (1,6), (2,8), (3,1), and (4,0)
