Three-quarters of a number is 15.<br> Work out four-fifths of the number.
azamat

Answer:

16

Step-by-step explanation:

let the number be x , then

\frac{3}{4} x = 15 ( multiply both sides by 4 to clear the fraction )

3x = 60 ( divide both sides by 3 )

x = 20 , then

\frac{4}{5} × 20 = 4 × 4 = 16

Answer:

Equation: 5w = c

What else would need to be congruent to show that triangle ABC cong Triangle XYX by ASA?
Alex777 [14]
<h3>Answer: First choice.  angle C = angle Z</h3>

Explanation:

AC = XZ shows that the horizontal pieces are congruent. This is the "S" of "ASA" as it stands for the pair of congruent sides. We are also given angle A = angle X. This is one of the "A"s in "ASA" as it stands for pair of congruent angles.

What we're missing is the other pair of angles. We must pick C and Z because they help sandwich the two sides mentioned above. ASA has the two angles surrounding the sides; or the sides are between the angles. We can't pick B and Y, unless we were doing AAS which is a similar related idea. The order matters when it comes to ASA and AAS. However, AAS is the same as SAA.
