Answer:
so x = 5 is not true statement
Step-by-step explanation:
well to prove x = 5 you need to get get alone or solve for x
3x = 10-5 --> 3x = 5
now you need to get x alone do this by dividing 3 by both sides
3x = 5 --> x = 5/3
x = 1.6
Answer:
£0.85 for each
£1.70 for both
Step-by-step explanation:
Variable x = cost of baked beans
2.30 + 2(2.60) + 2x = 10 - 0.80
Use PEMDAS
2.30 + 5.20 + 2x = 10 - 0.80
7.50 + 2x = 9.20
Subtract both sides by 7.50
2x = 1.70
Divide both sides by 2 to isolate the variable
x = 0.85
Let's check our work by plugging this into our original equation
2.30 + 2(2.60) + 2(0.85) = 10 - 0.80
2.30 + 5.20 + 1.70 = 10 - 0.80
7.50 + 1.70 = 9.20
9.20 = 9.20
Our number is correct
Answer:
7.70%
Step-by-step explanation:
Total length of race = 5k
Actual time taken to run the race = 26 minutes
Marcos time = 28 minutes
Percentage error = difference in value / actual time × 100
= (28 - 26) / 26 × 100
= 2 / 26 × 100
= 0.077 × 100
= 7.70%
