X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
Step-by-step explanation:
d is the correct ans
see,
As the bases are equal we can cut the bas,
<h2>C. ΔQRS ≅ ΔGFE </h2>
ΔQRS ≅ ΔGFE because :
∠Q = ∠G = 55°( corresponding part )
∠R = ∠F = 60° ( corresponding part )
∠S = ∠E = 65° ( corresponding part )
QS = GE = 16 ( corresponding part )
Therefore , the correct answer is :-
<h3>C. ΔQRS ≅ ΔGFE </h3>
You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7
Hope I could help :)
Answer:
5y=2
Step-by-step explanation:
8y + 4 = 6 + 2y + 1y
Combine like terms
8y+4 = 6+3y
Subtract 3y from each side
8y-3y+4 = 6+3y-3y
5y +4 = 6
subtract 4 from each side
5y+4-4 = 6-2
5y=2
