Answer:
x=8
Step-by-step explanation:
48=5(2x-7)+3
Use the distributive property
48=10x-35+3
Combine like terms
48=10x-32
Add 32 to both sides to cancel out the negative 32
80=10x
x=8
Answer:
The answer to your question is Area = 50.27 m²
Step-by-step explanation:
Data
Area = ?
Diameter = 8 m
π = 3.1416
Formula
Area = πr²
Process
1.- Find the length of the radius
radius = diameter/2
- Substitution
radius = 8/2
- Result
radius = 4 m
2.- Find the area of the circle
Area = (3.1416) (4)²
Simplification and result
Area = (3.1416) (16)
Area = 50.27 m²
Step-by-step explanation:
Since we are not told what to look for, we can as well look for the value of x, m∠SQT and m∠RQS
Given
m∠RQS=(4x-20)°
m∠SQT=(3x+14)°
m∠RQT=155°
The addition postulate is true
m∠RQT= m∠RQS + m∠SQT
Substitute the given parameters into the formula
155 = 4x-20+3x+14
155 = 7x-6
7x = 155+6
7x = 161
x = 161/7
x = 23
Solve for m∠RQS
m∠RQS = 4x-20
m∠RQS = 4(23)-20
m∠RQS = 92-20
m∠RQS = 72°
Solve for m∠SQT
m∠SQT = 3x+14
m∠SQT = 3(23)+14
m∠SQT = 69+14
m∠SQT = 83°
