Answer:
x=45degrees because there is 180 degrees on the straight lne and the first one is 90 degeeese and since it is split in half 90/2 is 45
Step-by-step explanation:
Lets say a fork costs x $. Therefore a spoon costs 2x $.
2x + x = 6. => 3x = 6. => x=2
so:
a) A spoon costs: 2x = 2 × 2 = $4
b) (12 × 4) + (10 × 2) = $68
Answer:
We want a line that passes through the point (4, 7/2)
and we have no other information of this line, so we can not fully find it, but we can find a general line.
We know that a line can be written as:
y = a*x + b.
Now we want that, when x = 4, we must have y = 7/2.
7/2 = a*4 + b
b = -a*4 + 7/2
Then we can write this line as:
y = a*x - a*4 + 7/2.
Where a can take any value, and it is the slope of our line.
Answer:
25 minutes
Step-by-step explanation:
When there are to people washing one elephant they will take half the time.
So half of the longest time will be the answer to the question.
Mary takes longer then Nigel so once Nigel is finished Mary will still wash her side for 5 minutes extra.
