Solve for the variable b in this equation 5a(b-c)=d

earnstyle [38]

Answer:

b = d/5a + c

Step-by-step explanation:

5a(b-c)=d

Divide by 5a on both sides

(5a/5a)(b-c)=d/5a

b-c = d/(5a)

Add c to each side

b-c+c = d/5a + c

b = d/5a + c

John predicts his football team will score 67 points in the next game. If John's team actually scored 42 points, what was John's

dolphi86 [110]

Answer:

The error percentage was 59.5%

Step-by-step explanation:

John predicts his football team will score 67 points in the next game.

Prediction score = 67

But John's team actually scored 42 points.

Actual scored = 42

We need to find the error percentage of John's using formula.

$\%=\dfrac{\text{|Prediction-exact|}}{exact}\times 100$

$\%=\dfrac{\text{|67-42|}}{42}\times 100$

Percentage error $=\dfrac{25}{42}\times 100$

$=59.52\%$

We need to round off to nearest tenth.

Hence, The percentage error was 59.5%
