ANSWER:
v = 3 is only a solution to equations 1 and 5.
STEP-BY-STEP EXPLAINATION:
Equation 1:





Therefore, v = 3 is a solution.
Equation 2:





Therefore, v = 3 is not a solution.
Equation 3:




Therefore, v = 3 is not a solution.
Equation 4:





Therefore, v = 3 is not a solution.
Equation 5:





Therefore, v = 3 is a solution.
Answer:
<u>77.4 degrees and 12.6 degrees</u>
Step-by-step explanation:
Let the angles be x and x - 64.8.
Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :
x + x - 64.8 = 90
2x = 154.8
x = <u>77.4 degrees</u>
x - 64.8 = 77.4 - 64.8 = <u>12.6 degrees</u>
7x - 1 + 6x - 1 = 180
13x - 2 = 180
13x = 182
x = 14

Answer: 30p
Step-by-step explanation:
Cost of donuts in the first shop £1.20
Cost at the second shop at 25% higher
= 1.20 x 1.25 = 1.50
Difference in price
= 1.50 - 1.20 = 0.30
