Answer:
A hope it helps :)
Step-by-step explanation:
A set of equation can be set up:
a=b+15
3(a+b)=345
where a is the faster and b is the slower bus.
substitute b+15 into the second equation, so 6b+45=345, and 6b=300, therefore b=50.
we can then figure out that a=65
Answer:
The correct options are;
A. 1·2 = 2
B. 1·1 = 1
E. 1 + 1 = 2
Step-by-step explanation:
Given that the equations 1.2 = 2 and 1.1 = 1 are correctly written as 1·2 = 2 and 1·1 = 2, we have;
The product of any number and one is equal the same number, that is a × 1 = a
Whereby we have the expression 1·2 which is 1 × 2, we therefore have;
1 × 2 = 1 · 2= 2
B. Similarly we have;
1 · 1 = 1 × 1 = 1
Also, 1 + 1 = 2 is correct as the sum of two numbers is equal to the sum of the count of the numbers, therefore;
E. 1 + 1 = 2 is correct.
