Hello,
Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3
Proof: a+b+c=15.9+5.3+31.8=53
The second number is 5.3
D. 160 you simplify the expression to get your answer.
Ok? is the question your asking, for what x equals or what the equation equals
You can solve this in 2 easy steps: 1, multiply 44.55 by .17 (44.55 * .17 = 7.57) then adding the number you get to 44.55 (44.55 + 7.57 = 52.12). Your answer is D.
Answer:
The correct answer is 25
Step-by-step explanation:
See the attached figure.
SAS similarity theorem mean that when two triangles have corresponding angles are congruent and corresponding sides with identical ratios the triangles are similar.
So, if ΔONM similar ΔSRQ by the SAS similarity theorem
∴∠N = ∠R
And
![\frac{NM}{RQ} =\frac{NO}{RS}](https://tex.z-dn.net/?f=%5Cfrac%7BNM%7D%7BRQ%7D%20%3D%5Cfrac%7BNO%7D%7BRS%7D)
given that NM = 10 , NO = 8 , QR = x , RS = 20
∴![\frac{10}{x} =\frac{8}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7Bx%7D%20%3D%5Cfrac%7B8%7D%7B20%7D)
∴![x=\frac{10*20}{8} =25](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%2A20%7D%7B8%7D%20%3D25)
So, the value of x will make ONM similar SRQ by the SAS similarity theorem = 25
