Mathematics
1 answer:
Nana76 [90]2 years ago
7 0

Answer:

Step-by-step explanation:

1) a + $5.92 = $12.29

subtract 5.92 from both sides

a = $6.37

Third option, a = $6.37

2) Multiply the equation by j to get it to the left side

42 = 6j

Divide both sides by 6

42/6 = 7

Answer: 7

3) 9 + 8 = 17           No

   9 x 3 = 27          Yes

   9 + 3 = 12           No

   9 - 5 = 4             Yes

   9/3 = 3                No

4) 15.32 + c = 29.00

c = 13.68 is the most expensive you can go, so it would be the soccer ball, since it is the most expensive item under 13.68.

5) 6 x 6 = 36 .    False

   5 + 6 = 11 .       True

   6/2 = 3 .          True

 17 - 6 = 11           True

Hope this helps :)

Are triangles the congruent? Write the congruency statement.
Ede4ka [16]

Answer:

Yes. but under the next condition m∠Q ≅ m∠T

Step-by-step explanation:

If the circular arc label of the angles ∠Q and ∠T means that they are congruent (equal) or m∠Q ≅ m∠T, in that case we can prove that  ΔPQR is congruent with ΔSTU or ΔPQR≅ΔSTU.

We need three elements to form congruency statement.

1.  Sides PQ ≅ ST = 4 ft

2. Angles m∠Q ≅ m∠T

2. Sides QR ≅ TU = 6 ft

Based on the SAS statement ( Side-Angle-Side) we prove that:

ΔPQR ≅ ΔSTU.

If they are congruent, every corresponding elements are congruent:

Sides PR = SU => 3y - 2 = y + 4 => 3y - y = 4 + 2  => 2y = 6 => y = 6/2 = 3

y = 3  => PR = 3 · 3 - 2 = 9 - 2 = 7  =>  PR = 7 ft

Perimeter of ΔPQR is

P = PQ + QR + PR = 4 + 6 + 7 = 17 ft

P = 17 ft

God with you!!!

What is the slope of the line graphed below? -3,4) 3,2) ​
insens350 [35]

Answer:

-0.33

Step-by-step explanation:

x1 = -3, y1 = 4, x2 = 3 y2 = 2

m = y2 - y1 / x2 -x1

m = 2 - 4 / 3 - (-3)

m = -2/ 6

m = -0.33
