First, let's convert 1 km 125 m into metres.
1 km = 1000 m
1.125 km - 1,125 m
On Tuesday, Eric biked 375 metres fewer than on Monday.
1125 - 375 = 750 m
Eric biked 750 m on Tuesday.
On both days he biked 1125 + 750 = 1,875 m or
1 kilometre and 875 metres
Answer:
A. If a bird is a crow, then it is black.
Step-by-step explanation:
I'm guessing you mean a^2? if so then,
a^2+28a+27=
(a+1)(a+27)
Answer:
Rose is 34.
Anne is 14.
Step-by-step explanation:
Let rose be x years age now and anne be y years old now. Then:
x + 6 = 2 (y + 6)
x - 4 = 3(y - 4)
Subtracting:
6 - -4 = 2y + 12 - (3y - 12)
10 = - y + 24
-y = -14
y = 14
Substituting for y:
x + 6 = 2(14+6)
x = 40 - 6 = 34.
What you're doing is the same as looking at a triangle that has already been drawn. What you have so far is correct and you are doing it right. Your final step is to square the 3 and the 8 so that you get 9+64=c squared. 64 + 9 is 73, and the square root of 73 is 8.53.
