Answer:

4.5 pounds

Step-by-step explanation:

Convert them both to improper equations.

2 3/4 = 11/4

1 3/4 = 7/4

Then add.

11/4 + 7/4 = 18/4

Then simplify.

18/4 = 4 2/4 = 4.5

Answer:

4 2/4

Step-by-step explanation:

this is because you can add the whole numbers already after that you should add the numerators of the fraction giving you 6/4. Which can be simplified to 1 2/4. If you add the previous whole numbers then you would get 4 2/4.

Answer: 21

Step-by-step explanation:

$N-\left(2\cdot \:7\right)=7$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$N-2\cdot \:7=7$

$\mathrm{Multiply\:the\:numbers:}\:2\cdot \:7=14$

$N-14=7$

$\mathrm{Add\:}14\mathrm{\:to\:both\:sides}$

$N-14+14=7+14$

$\mathrm{Simplify}$

$N=21$

-------100 POINTS------<br> Complete the proof of the Pythagorean theorem.

KIM [24]

Step-by-step explanation:

Complete the proof of the Pythagorean theorem is given below.

Statement Reason

1. ΔABC is a right triangle, with a 1. Given

right angle at ∠C

2. Draw an altitude from point C 2. From a point not on a line, exactly

to AB one perpendicular can be drawn through the point to the line

3. ∠CDB and ∠CDA are right 3. Definition of altitude

angles

4. ∠BCA ≅ ∠BDC 4. All right angles are congruent

5. ∠B ≅ ∠B 5. $Reflexive\:Property$

6. ΔCBA ~ ΔDBC 6. AA Similarity Postulate

7. $\frac{a}{x}\:=\:\frac{c}{a}$ 7. $Polygon\:Similarity\:Postulate\:\:\:$

8. $a^{2} = cx$ 8. $Cross\:Multiply\:and\:Simplify$

9. ∠CDA ≅ ∠BCA 9. $All\:Right\:Angles\:are\:Congruent$

10. ∠A ≅ ∠A 10. $Reflexive\:Property$

11. ΔCBA ~ ΔDBA 11. AA Similarity Postulate

12. $\frac{b}{y}\:=\:\frac{c}{b}=$ 12. $Polygon\:Similarity\:Postulate$

13. $b^2\:=\:cy$ 13. $Cross\:Multiply\:and\:Simplify$

14. $a^2\:+\:b^2\:=\:cx\:+cy$ 14. $Addition\:Property\:of\:Equality$

15. $\left(CB\right)^2+\left(CA\right)^2=\left(AB\right)\left(DB+BA\right)$ 15. Distributive Property

16. $x + y = c$ 16. $Segment\:Addition\:Postulate$

17. $a^2\:+\:b^2\:=\:c^2$ 18. $Substitution\:Property$
