How many solutions are there for the following equation? Why?
8(x + 9) = 72 – 5x
Select the option that correctly answers both questions.
1 There is one solution, because the coefficients of the variables on both sides of the equation are different.
2 There is one solution, because the coefficients of the variables on both sides of the equation are the same.
3 There are no solutions, because the coefficients of the variables on both sides of the equation are different.
4 There are no solutions, because the coefficients of the variables on both sides of the equation are the same.
Answer:
I think 2? maybe 1.
Step-by-step explanation:
because it becomes 8x+72=72-5x which can then become 3x=0 then x=0/3 and 0/3=0 so x=0

A=?
b=?
C =?
Can someone tell me the answer please
Answer:
Below.
Step-by-step explanation:
a = 37 degrees ( vertical angle to 37 )
c = 180 - 37 = 143 degrees (adjacent angles add up to 180).
b = 180 - 37 - 109 = 34 degrees (angles in a triangle sum to 180 degrees).
a = 37 degrees
c = 180 - 37 = 143 degrees.
b = 180 - 37 - 109 = 34 degrees

which fact helps you prove the isosceles triangle theorem, which states that the base angles of any isosceles triangle have equal measure?
Answer:
If one angle of a triangle is larger then another angle, then the side opposite then the larger angle is longer then the side oposite to the smaller angle
Step-by-step explanation:
Vickie was born on this day in 1981. Including leap years, how many seconds old is Vickie?
Answer:
Vickie is about 1,256,428,800 seconds old.
Step-by-step explanation:
1 year = about 31,536,000 seconds
2021 - 1981 = 40
39 × 31,536,000 = 1,229,904,000 (total 365-day years in seconds discluding this year)
____________________________________________
Now, add the leap days.
Since 1981, there has been 10 leap years, meaning 10 leap days.
1 leap day = about 86,400 seconds
86,400 × 10 = 864,000 (total leap day seconds)
____________________________________________
Today is 10/24/2021, so it is the 297th day of the year.
1 day = exactly 86,400 seconds
297 × 86,400 = 25,660,800 (total seconds this year)
____________________________________________
Add all values to get the total amount of seconds.
1,229,904,000 + 864,000 + 25,660,800 = 1,256,428,800 (total seconds of how old is Vickie)

Answer:
29+8x-3=0
Step-by-step explanation:
esto es lo que se esque no se si lo has escrito bien
Answer:
x=-4
Step-by-step explanation:
Switch sides:
−8x−3=29
Add 3 to both sides:
−8x−3+3=29+3
Simplify:
−8x=32
Divide both sides by −8:
−8x/−8 = 32/−8
Simplify again for the result:
x=−4

As shown on the diagram below ABC ~ DEF, AB=7x, BC=4, DE=7 and EF=x what is the length of AB?
==========================================================
Explanation:
We're told that [tex]\triangle ABC \sim \triangle DE F[/tex] which means triangle ABC is similar to triangle DEF. The order of the letters is important as you'll see in the next two paragraphs.
AB and DE are the first two letters of ABC and DEF respectively. These two sides pair up as one corresponding pair. This forms the fraction AB/DE.
Through similar logic, we get the fraction BC/EF. We have BC and EF as the last two letters of ABC and DEF respectively. This fraction is equal to the previous fraction we set up (due to similar triangles having equal proportions).
Once again, the order of the letters matters to tell us how the sides and angles pair up together.
-----------------
In short, the key takeaway from that last section is that we can form this equation:
AB/DE = BC/EF
From here, we apply substitution and solve for x
So,
AB/DE = BC/EF
7x/7 = 4/x
7x*x = 7*4 .... cross multiplication
7x^2 = 28
x^2 = 28/7
x^2 = 4
x = sqrt(4)
x = 2
We only consider the positive square root because x is some side length. Negative x values are not allowed.
To wrap things up, use that x value to find AB
AB = 7x = 7*2 = 14

Rationalize the denominator.
– 5x4
✓4x +7
The question is asking us to make the denominator a rational function by finding a way to remove the square root without changing the value of the overall function.
We can do this by multiplying the denominator and numerator by the √(4x + 7), since multiplying a root term by that root term = the number being rooted (√x × √x = x).
- 5x⁴ × √(4x + 7) = (-5x⁴)(√(4x + 7))
√(4x + 7) √(4x + 7) 4x + 7
2x+34=6-5x pls help show work I’ll mark as brainliest!!
Answer:
x = -4
Step-by-step explanation:
2x + 34 = 6 - 5x
Subtract 34 from both sides.
2x = -28 - 5x
Add 5x to both sides.
7x = -28
Divide both sides by 7.
x = -4
Proof:
2x + 34 = 6 - 5x
Substitute variable.
2(-4) + 34 = 6 - 5(-4)
Multiply.
-8 + 34 = 6 + 20
Add.
26 = 26
Answer:
x = -4
Step-by-step explanation:
2x+34=6-5x
+5x +34 = 6+5x
------------------------
7x +34 = 6
7x -34 = -34
-----------------
7x = -28

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]
Answer:
- 22.667
Step-by-step explanation:
1.5^3 = 1.5 x 1.5 x 1.5 = 3.375
- 3.64 ⋅ | 5.3 | - 1.5^3
= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3
= ( - 3.64 ⋅ 5.3 ) - 1.5^3
= ( - 3.64 x 5.3 ) - 1.5^3
= - 19.292 - 3.375
= - 22.667
