Solve the equation square root 2x – 7 + x = 5 algebraically, and justify the solution set
yarga [219]

Answer: x=4

Step-by-step explanation:

2x-7+x=5

Group like terms:

\left(2x+x\right)-7=5

Simplify the arithmetic:

3x-7=5

Add 7 to both sides:

3x-7+7=5+7

Simplify the arithmetic:

3x=5+7

Simplify the arithmetic:

3x=12

Divide both sides by 3:

\frac{3x}{3}=\frac{12}{3}

Simplify the fraction:

x=\frac{12}{3}

Find the greatest common factor of the numerator and denominator:

x=\frac{4\cdot 3}{1\cdot 3}

Factor out and cancel the greatest common factor and the answer will be:

x=4

Can someone please help me find the measure of angle ABO?
lara [203]

Answer:

m<ABO = 22 deg

Step-by-step explanation:

A tangent intersects a circle at the point of tangency making a right angle with the radius drawn to that point. That means that <BAO is a right angle and measures 90 deg. That makes the other two angles of the triangle complementary with a sum of 90 deg.

m<O + m<B = 90

68 + m<B = 90

m<B = 22

Answer: m<ABO = 22 deg
