Answer:

5x + y = 9

3x + 2y = 4

-10x - 2y = -18

 3x + 2y = 4

-7x = -14

x = 2

5(2) + y = 9

10 + y = 9

y = -1

(2, -1)

the answer is c

dem82 [27]

Answer:

Probability of getting a number which is not 2 = 7/8

Step-by-step explanation:

Given;

Total number of faces = 8

Number of face with 2 = 1

Number of face with 3 = 2

Number of face with 4 = 1

Number of face with 7 = 3

Number of face with 9 = 1

Find:

Probability of getting a number which is not 2

Computation:

Probability of not an event = 1 - [Number of favourable outcomes / Total number of outcomes]

Probability of getting a number which is not 2 = 1 - [1/8]

Probability of getting a number which is not 2 = [8-1] / 8

Probability of getting a number which is not 2 = 7/8

Name a pair of overlapping congruent triangles in each diagram. State whether the triangles are congruent by SSS, SAS, ASA, AAS,
MariettaO [177]

Answer:

ΔPTS≅ΔRTA by AAS axiom of congruency

Step-by-step explanation:

Consider ΔPQA and ΔRQS

∠PQA=∠RQS     (Vertically Opposite Angles)

∠QAP=∠QSR     (Complementary of two equal angles, ∠RAT and∠PST)

Due to angle sum property of a triangle, we come to the conclusion that

∠APQ=∠SRQ

Consider ΔPTS and ΔRTA

TA=TS  (Given)

∠RAT=∠PST(Given)

∠APQ=∠SRQ (Proved above)

Therefore, ΔPTS≅ΔRTA by AAS axiom of congruency.

Jose worked n hours at 8.75 dollars per hour he made a total of $61.25 write an expression that represents the total number of h
Nitella [24]

Answer:

n = P/8.75

Step-by-step explanation:

Jose’s pay (P) depends on the number (n) of hours he works.

P = 8.75n     Divide both sides by 8.75

n = P/8.75

=====

P = $61.25

n = 61.25/8.75

n = 7 h

Jose worked for 7 h.
