All we need to do is get the ? by itself in both equations.
-4 - ? = - 7
-? = -7 + 4
-? = -3
? = 3
? - ( -3) = 5
? + 3 = 5
? = 5 - 3
? = 2
Answer:
First ?: 3
Second ?: 2
Step-by-step explanation:
Do the inverse operation of what is shown to get the answer.
First ?:
-4 - ? = -7
-7 + 4 = -?
-3 = -?
3 = ?
Second ?:
? + 3 = 5 (Two negatives in a row make a positive.)
5 - 3 = ?
2 = ?

Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

Sarah is finding the surface area of a cube. Find the surface area of the cube with dimensions of 8 cm each
Answer:
384 cm^2
Step-by-step explanation:
A = 6a^2 (a = side length)
A = 6(8^2)
A = 6(64)
A = 384 cm^2
More explain stuff:
a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

How many 2-liter bottles of soda will you need to fill ten 500 milliliter containers?
Answer:
2.5 bottles
Step-by-step explanation:
10 * 500 ml = 5000 ml
5000 ml = 5 l
5/2 = 2.5
2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.
How many milliliters in 1 liter?A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.
1 liter = 1000 milliliters
Ten 500 milliliter containers
10 × 500 ml = 5000 ml
5000 ml = 5 l
2-liter bottles of soda will you need
5/2 = 2.5bottles
Therefore, 2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

Read the problem. 10% of the students at Harris Middle School are on the yearbook committee. If 30 students are on the yearbook committee, how many students are at Harris Middle School? Pick the model that represents the problem. How many students are at Harris Middle School?
Answer:
100%
300 students
Step-by-step explanation:
let b = number of students in the school
this equation can be derived = 10% x b = 30
to find b, divide both sides of the equation by 10%
b = 30/0.1 = 300
we want find the total number of students in the school, which is equal to 100%

Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth and h is the height.
The volume of the tank is :
[tex]V=4\times 2.5\times 2.4[/tex]
[tex]V=24[/tex]
Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is
[tex]\dfrac{24}{3}=8[/tex]
The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.

[tex] \underline{ \underline{ \bf{Question}}}: [/tex] In the given figure , ABC is a triangle in which AB = AC. Also a circle passing through B and C intersects the sides AB and AC at the points D and E respectively. Prove that AD = AE.
~Thanks in advance! :)
Answer:
See Below.
Step-by-step explanation:
We are given that ABC is a triangle in which AB = AC.
A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.
And we want to prove that AD = AE.
By the secant-secant theorem (shown below), we know that:
[tex]AD(AB)=AE(AC)[/tex]
We are given that AB = AC. So, by substitution:
[tex]AD(AB)=AE(AB)[/tex]
And by dividing both sides by AB (AB ≠ 0), we acquire:
[tex]AD=AE[/tex]

For which of the following is x = -5 a solution? Select all that apply.
Answer:
Options 2, 3, 4, 5 are the solutions.
Step-by-step explanation:
Option 1).
x + 10 = -5
x = -10 - 5
x = -15
Therefore, x = -5 is not the solution.
Option 2).
-x² + 50 = 25
-x² = 25 - 50
-x² = -25
x² = 25
x = ±5
Therefore, x = -5 is a solution
Option (3)
|2x| = 10
2x = ± 10
x = ± 5
Therefore, x = -5 is a solution.
Option (4)
x < 0
Since, -5 < 0
Therefore, x = -5 is a solution.
Option (5)
2x < 10
x < 5
Since, -5 < 5
Therefore, x = -5 is a solution.
Options 2, 3, 4, 5 are the solutions.
