<span>–4.75 + 2.19
The easiest way to do this (in my opinion) is to switch signs:
4.75 - 2.19:
4.75
-2.19
=2.56
Finally, put the - sign back to get
-2.56
The answer is B.

Answer:
2.456 x 10^11
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
Statement: Triangle ACD is congruent to Triangle BCD
Reason: SSA (Side, Side, Angle)
Answer: 7/8
Step-by-step explanation:
You can change all the fractions to have equivalent denominators.
The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.
1 1/4 = 1 2/8 = 10/8.
3/8 = 3/8.
Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.
10/8 - 3/8 = 7/8.
Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.
