Answer:
b= 29/11
Step-by-step explanation:
2b+8−5b+3=−13+8b−5
Step 1: Simplify both sides of the equation.
2b+8−5b+3=−13+8b−5
2b+8+−5b+3=−13+8b+−5
(2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)
−3b+11=8b+−18
−3b+11=8b−18
Step 2: Subtract 8b from both sides.
−3b+11−8b=8b−18−8b
−11b+11=−18
Step 3: Subtract 11 from both sides.
−11b+11−11=−18−11
−11b=−29
Step 4: Divide both sides by -11.
−11b/−11 = −29/−11
b= 29/11
Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
You can find percentages like this by taking the total number of questions dividing it by 100 to find out how much each question was worth, then multiplying by the number correct.
So, 85 ÷ 100 ≈ 1.18
1.18 x 68 ≈ 80
So, the score was 80%.
78.74 feet would be equivalent to 24m
