Answer:
Step-by-step explanation:
= (12-8)/12 × 100%
= 4/12 × 100%
= 100/3%
= 33.33%
Answer:
x = 22°
y = 26°
z = 48°
Step-by-step explanation:
∠PQS and ∠QSR is a pair of alternate interior angles
plus PQ is parallel to SR
then
x = 22°
SPR is an isosceles triangle then m∠PRS = 66°
Therefore x + y = 180-(66+66) = 180-132 = 48
then y = 48 - x = 48-22 = 26
finally, z = x + y = 48
Answer:
22 for x 45 for 4x+3 36 for 3x+2

Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!
