-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.

A truck used 28 gallons of gas when driving 1008 miles. What is the rate per gallon?
Answer:
36 miles per gallon (mpg)
Step-by-step explanation:
To solve this problem, you are going to divide the total miles driven by the total gallons of gas used. This will mean that you will divide 1008 miles by 28 gallons. This will result in a final answer of 36 miles per gallon. My work is below and please let me know if you have any questions!
1008 / 28 = 36 miles per gallon
Answer:
1 gallon = 36 miles
Step-by-step explanation:
In order to find out you need to divide 2008 miles by 28 gallons

Calculate the area of the triangle.
State the units of your answer.
6 cm
6 cm
Answer:
18 cm
Step-by-step explanation:
I hope i'm correct..
So first the formula of finding the area of a triangle is
A= 1/2 (b) (h)
If we turn the triangle we can do that.
so,
A=1/2 (6)(6)
A=1/2(36)
1/2 of 36 is 18
So, the answer is 18 cm
Answer:
18 Cm
Step-by-step explanation:
[tex]A = \frac{ab}{2}[/tex]
Area = 6 times 6 over 2
How do I do this?
Write the equation of a cubic function with the following transformations.
1) Horizontal shift to the right 5 units
2) Vertical shift up 4 units
3) Vertical compression by a factor of ½
Answer:
1/2f(x-5)+4
Step-by-step explanation:
the base function x^3 then the transformations happen.
1) f(x) becomes f(x-5)
2)+4 is added to the end of the equation f(x-5)+4
3)add 1/2 to the beginning of f(x) 1/2f(x-5)+4
Input any cubic function for f(x)
Find the GCF of 5y5 and 50y2.
Answer: [tex]5y^2[/tex]
Step-by-step explanation:
Given
[tex]5y^5\ \text{and}\ 50y^2[/tex]
GCF or HCF of the two is the highest common factor
[tex]\Rightarrow 5y^5=5\times y^2\times y^3\\\Rightarrow 50y^2=5\times y^2\times 10[/tex]
It is clear GCF is [tex]5y^2[/tex]

The probability of rolling a number cube and getting a 6 and 3.
We have to find out the probability of getting 6 and 3,
Since this only one roll it is not possible to get 2 numbers in one roll
So, I will presume you want the probability of getting 6 or 3,
Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes
Number of favorable outcomes = {3,6} = 2 outcomes
Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]
= 2/6
= 1/3 or 0.33333%
Therefore the probability of rolling 6 or 3 is one in three chances

Arc AD=98 and I need help with both problems below
Answer:
arc DC = 64
angle DCQ = 32
Step-by-step explanation:
Hello There!
The circumference of a normal circle is 360
Given that arc AD = 98 and having found arc ABC we can find arc DC by subtract the known arcs from 360
360 - 98 - 198 = 64
Hence arc DC = 64
The problem wants us to find angle DCQ having found arc DC
Remember like stated before an included angle is equal to 1/2 its opposite arc
64/2=32
so angle DCQ = 32
The measures of the angles of a triangle are in a ratio 2/3 / 5 . What are the measures of the angles?
Answer:
36°, 54°, 90°
Step-by-step explanation:
2:3:5 equal 10 parts in total
there are a total of 180 degrees in a triangle
180°/10 = 18°
2(18°) = 36°
3(18°) = 54°
5(18°) = 90°

1) f(x)=(x - 3)(x - 5)
A f(x) = x2 - 8x+15
B. f(x) = x2 -15x-8
C. $(x) = x? - 8x-15
which is the equivalent?
Answer:
Step-by-step explanation:
f(x)= (x - 3)(x - 5)
f(x) = x^2 - 5x - 3x + 15
f(x) = x^2 - 8x + 15

The area of a gymnasium is (27x + 18) square units. Factor
27x + 18 to find possible dimensions of the gymnasium.
Answer:
9 by (3x + 2) units
Step-by-step explanation:
Note that 9 is a factor of both 27x and 18. Therefore,
27x + 18 factors into 9(3x + 2).
Possible dimensions of the gym are 9 by (3x + 2) units.

When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
-0.8x+4.8y+16
0.8x-4.8y+16
-0.8x-4.8y+4
0.8x+4.8y+4
Answer:
-0.8x + 4.8y + 16
Step-by-step explanation:
4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x + 2.5y - 1.3y + 4)
= 4( -0.2x + 1.2y + 4)
= 4*(-0.2x) + 4 *1.2y + 4*4
= -0.8x + 4.8y + 16
Answer:
-0.8x + 4.8y + 16
