Answer:
$1.5b
Step-by-step explanation:
If a bakery sells 5 bagels for $7.50, we are to find the equation that will represent the cost of b bagels. This can be gotten using the equality postulate as shown;
5 bagels = $7.50
b bagel = $c
Cross multiply
5*c = 7.50b
Divide both sides by 5
5c/5 = 7.50b/5
c = 1.5b
Hence the cost of b bagel c is $1.5b
I believe the answer is 14.29 miles
Answer:
3x-1
Step-by-step explanation:
3x^2+2x-5=3x-1 x1-25
Answer:
C
Step-by-step explanation:
Given
tanθ =
=
This is a right triangle with legs 1 and 2
Using Pythagoras' identity
hypotenuse² = 1² + 2² = 1 + 4 = 5 ( take square root of both sides )
hypotenuse = 
θ is in the 3rd quadrant where sinθ < 0 , then
sinθ =
= -
← rationalise the denominator
= -
× 
= -
→ C
