Consider the equation 5 – 3(2x – 7) = 12 – 5(x – 2). Is x = 2 a solution to this
equation? Is x = 4 a solution to this equation?
Answer:
[tex]\sf x=4[/tex]
Step-by-step explanation:
[tex]\sf 5 - 3(2x - 7)=12 - 5(x - 2)[/tex]
To get rid of the parentheses, we'll apply the distributive property. Staring with the left side, multiply -3 by (2x-7).
[tex]\sf 5 - 6x+21=12 - 5(x - 2)[/tex]
5+ 21= 26
[tex]\sf 26 - 6x=12 - 5(x - 2)[/tex]
Now, let's do the same thing to the right side. Multiply -5 by (x-2) »12−5x+10, than add 12+ 10 = 22 .
[tex]\sf 26 - 6x=22 - 5x[/tex]
Combine like terms.
[tex]\sf 26 - x=22[/tex]
Subtract 26 from both sides.
[tex] \sf - x= - 4[/tex]
Multiply both sides by -1.
[tex]\sf x=4[/tex]

B is the midpoint of AC, what in the measure of AB if AC 82cm?
Answer:
AB = 41 cm
Step-by-step explanation:
If B is the midpoint of AC, then B splits AC into 2 equal halves: AB & BC.
Therefore, AB = ½ of AC.
Given, AC = 82 cm.
So,
AB = ½ × AC
AB = 82/2
AB = 41 cm

which equation represents a line that passed through (2,-1:2) and has a sloe of 3
The equation that represents a line that passed through (2,-1:2) and has a slope of 3 is y = 3x - 18
How to determine the equation of the line?The points are given as:
(x1, y1) = (2, -12)
The slope is given as:
m = 3
The equation of the line is calculated using:
y = m(x - x1) + y1
So, we have:
y = 3(x - 2) - 12
Open the bracket
y = 3x - 6 - 12
Evaluate
y = 3x - 18
Hence, the equation of the line is y = 3x - 18

Step-by-step explanation:
Please solve with explanation (high points)
The measure of the length GF is 4.2 units and IH is 2.27 units. Then the measure of angle ∠ACB will be 24.35°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangle ΔABC and triangle ΔGFC are similar triangles. Then we have
GF / BA = CF / BC
GF / 5.62 = 8.88 / 12.42
GF = 4.018
GF ≅ 4.02
The triangle ΔABC and triangle ΔIHC are similar triangles. Then we have
IH / BA = HC / BC
IH / 5.62 = 5.02 / 12.42
IH = 2.271
IH ≅ 2.27
Then the angle ∠ACB will be
∠ACB = tan⁻¹ (5.62 / 12.42)
∠ACB = tan⁻¹ 0.452
∠ACB = 24.35°
