Answer: In the exact order up to down: 80, 74, 110, 96, 80

Step-by-step explanation:

Do the equation

360=(x-6)+(x+30)+1.2x+x

we can simplify by doing

360=(x-6)+(x+30)+2.2x

=360=x-6+x+30+2.2x

=360=4.2x+24

=336=4.2x

=80=x

x=80

12) You can exchange $5 US dollars for L123 Honduran Lempiras. How many dollars can you exchange L2,300 for? ----​
Anit [1.1K]

Step-by-step explanation:

$5 US dollar = L123 Honduran Lempiras

L2300Honduran Lempiras = x ( Let $ be x)

By using chain rule, we get

5×2300 = 123×x

or, 11500 = 123x

or, x = 11500÷123

hence, x = 93.49593496

Me need help pweaseee can anyone help
Kryger [21]

Answer:

B

Step-by-step explanation:

A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.

A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.

I hope you find my answer and explanation to be helpful. Happy studying.
