Step-by-step explanation:
Given
Two similar triangles i.e. 
from the figure, In 
Also, In 
35 divided by 12 is 2
So D is the answer
4.8 x 10^-2
You can do this without a calculator
Explanation:
(3.2 x 10^-5) x (1.5 x 10^3)
First, you multiply 3.2 by 1.5 to get 4.8
Next, you add the exponents together: -5 + 3 = -2
Now, put everything into one answer (the 10 stays the same): 4.8 x 10^-2
Answer
t = 2
Step-by-step explanation
Simplify 5-(t+3).
-t+2=-1+2t-3
Subtract 3 from -1
-t+2=2t-4
Move all terms containing to the left side of the equation.
-3t+2=-4
Move all terms not containing t to the right side of the equation.
-3t=-6
Divide each term by -3 and simply.
t = 2
To do this, take Spencer's 85 pears and subtract Gwen's pears (p) to get the expression 85 - p.
