Answer:
x = 9, y = 2
Step-by-step explanation:
Given the 2 equations
x + 10y = 29 → (1)
x - y = 7 → (2)
Subtracting (2) from (1) term by term will eliminate the term in x
(x - x) + (10y - (- y)) = (29 - 7), that is
11y = 22 ( divide both sides by 11 )
y = 2
Substitute y = 2 in either of the 2 equations
Substituting in (2)
x - 2 = 7 ( add 2 to both sides )
x = 9
Oh.......kay.... Is that a question? It doesn't look like one.

Answer: 27.47
Step-by-step explanation:
(sin(70) * 10) / sin(20)) = 27.47
don't know much, but try that
Answer:
2. YM ≅ MQ
5. JK = 7 inches
7. SV = 12 meters
Step-by-step explanation:
2. YM ≅ MQ - corresponding sides of congruent triangles are congruent
5. If rectangle EFGH is congruent to rectangle JKLM, then corresponding sides are congruent. Side EF is congruent to side JK because E and F are first two letters in name of rectangle EFGH and J and K are first two letters in name of rectangle JKLM. Thus,
JK = 7 inches
7. If quadrilateral BCDE is congruent to quadrilateral STUV, then corresponding sides are congruent. Side BE is congruent to side SV because B and E are first and last letters in name of quadrilateral BCDE and S and V are first and last letters in name of quadrilateral STUV. Thus,
SV = 12 meters
