Distance=speed times time so time=60/40=3/2 = 1½ hours.
To find slope it is rise over run which is 20/60 but that can be reduced to 1/3. Do your equation of the line is y=1/3x
The diagonal of a rhombus divides it into two congruent isosceles triangles.
So ∠CBD ≅ ∠CDB
∠CBD + ∠CDB + 68 = 180
2∠CBD = 180 - 68 = 112
∠CBD = 56
We also have
∠BDE + ∠E + ∠DBE = 180
∠DBE = 180 - 73 - 36 = 71
∠EBC = ∠EBD - ∠CBD = 71 - 56 = 15
Answer: ∠EBC = 15 degrees
A box has six sides.
Using the dimensions of the box:
2 sides are 5 x 7
2 sides are 7 x 3
2 sides are 5 x 3
Now calculate the total area:
2 x 5 x 7 = 70
2 x 7 x 3 = 42
2 x 5 x 3 = 30
Total area = 70 + 42 + 30 = 142 square inches.
Answer:
6x - 3y
Step-by-step explanation:
First find the sum
10x - 2y - 3y
10x - 5y
Now do the subtraction
10x - 5y - (4x - 2y) Remove the brackets.
10x - 5y - 4x + 2y
10x - 4x = 6x
-5y + 2y = - 3y
Answer
6x - 3y
