Answer:
Step-by-step explanation:
I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:
1. 2x + 5 = 19
2. 14 - 3x = 23
3. 50x / 5 = 150
1. 2x + 5 = 19
Subtract 5
2x = 14
Divide by 2
x = 7
2. 14 - 3x = 23
Subtract 14 to the other side because we have to isolate the term with x in it
-3x = 9
Divide by -3
x = -3
3. 50x / 5 = 150
Multiply by 5 to isolate the value with x
50x = 750
Divide by 50
x = 15
I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!
Answer:
120°
Step-by-step explanation:
All the angles of an equilateral triangle are equal, and hence have a measure of 60°.
∵ ∠AGF is a part of equilateral Δ AGF, m∠AGF = 60°.
∵ ∠FGE is a part of equilateral Δ AGF, m∠FGE = 60°.
Also note that ∠AGE = ∠AGF + ∠FGE.
⇒ m∠AGE = m∠AGF + m∠FGE
⇒ m∠AGE = 60° + 60°
= 120°.
Answer:
1/2
Step-by-step explanation:
the dilation factor should be 1/2
- if u count the dots on the sides of the preimage there are 2 dots that's the length
- if u count the dots on the real image it's 4
- therefore 2/4 to it's lowest term is 1/2
- so 1/2 is the scale factor
