Solve for x.
-2x-3=-7
-2x-3=-7
add 3 to both sides
-2x=-4
isolate x by diving both sides by -2
Answer: x=2
Hope that helps!
Please mark brainliest
Answer:
x = 2
Step-by-step explanation:
The whole goal when solving problems like this is to get the x alone. So the first step would be to get the -3 over to the other side. To do this, you would add 3 to each side of the equation, so that the -3 on the left side cancels out.
-2x - 3 = -7
+3 +3
-2x = -4
The next thing you need to do is divide each side by -2. You would do this because right now, the equation reads "negative two times x equals negative four". When you divide a multiplication problem, it cancels out, so you are left with just the x.
-2x = -4
÷ -2 ÷ -2
x = 2
You now have the value of x.
Please let me know if you need any more help. I hope this explanation helps you understand a bit better. Have a great day! :)

Una garrafa de aceite equivale a 5 botellas y 3 garrafas es igual a 7, las cuales suman 11 litros, ¿Cuál es las capacidad de una botella y una garrafa?
Respuesta:
Botella, B = 0.5
Jarra, C = 2,5
Explicación paso a paso:
Dejar :
Garrafa = C
Botella = B
C = 5B - - - - 1)
3 garrafas más 7 botellas = 11 litros
3C + 7B = 11
C = 5B
3 (5B) + 7B = 11
15B + 7B = 11
22B = 11
B = 11/22
B = 1/2 = 0,5
Sustituyendo B = 0.5 en 1)
C = 5B
C = 5 (0,5)

3x = x + 10
2x = 10
x = 5
Answer:
Option D is correct.
Value of x is, 10 units.
Step-by-step explanation:
Given that:
From the given figure, we have;
AP = 3 units , PB = 6 units , QC = 20 units and AQ = x units.
then, by triangle proportionality theorem;
Substitute the given values, to find the value of x;
By cross multiply we have;
Divide both sides by 6 we get;
10 = x
Therefore, the value of x is, 10 units
Tamika makes $ 378.00 on the sale of a home theater system that costs $9.000.00. Express her rate of commission as a percent rounded to the nearest whole number
Answer:
4%
Step-by-step explanation:
commission rate = (amount earned on sales / total cost of items sold) x 100
[tex]\frac{378}{9000}[/tex] × 100 = 4.2%
To convert to the nearest whole number, look at the first number after the decimal,
if it is equal to or greater than 5, add 1 to the number before the decimalif it is less than five, add 0 to the number before the decimaltwo is less than 5, thus we would add zero to 4.
4.2% becomes 4%

Find the sum of the measures of the interior angles of a convex 45-gon.
Answer: 7740
Step-by-step explanation: take 180(n-45) and n represents the sides
The sum of the measures of the interior angles of a convex 45-gon.
is 7740.
What is a cube?It is a polygon having six faces.
The volume of a cube is a side³.
We have,
Polygon with side = 45
Sum of interior angles of any polygon = (n - 2) x 180 ______(1)
Now,
n = 45
So,
Substituting n in (1)
(n - 2) x 180
= (45 - 2) x 180
= 43 x 180
= 7740
Thus,
The sum of the measure of the interior angles is 7740.

What is a Two-way Table?A two-way table can be described as a table that displays the frequencies of two categorical variables, in such a way that, one category is represented by columns and the other by rows.
Given the information, the missing values in the two-way table would be:
Total number of boys enrolled = 150
Boys that enrolled in Algebra 1 = 2(46) = 92
Boys that enrolled in Algebra 2 = 150 - 92 - 46 = 12
Girls that enrolled in Algebra 1 = 150 - 54 - 28 = 68
