Answer: 10a, all of the numbers can be divided by 10a
10a (6x − 4y + 5z) = 60ax - 40ay + 50az
Answer:
Answer is 39.5
Step-by-step explanation:
firstly 7x+19=-79 so we divide-2x from -79 will give positive 39.5
Answer:
Side = 12 cm, side = 5 cm, side = 8 cm
Step-by-step explanation:
In order to form a triangle with non-zero area, the sum of the shortest two sides must exceed the longest side.
This will be the case for {5, 8, 12}, but not for any of the others.
___
The side lengths {5, 8, 13} will form <em>a triangle with zero area</em>. This is acceptable according to one version of the triangle inequality (a+b≥c) but not according to the other version (a+b>c). Since you are apparently expected to find one "right answer", we assume the answer you want is the one shown above.
Answer:
600
Step-by-step explanation:
240/1 ÷ 2/5
240x5 , 1x2 = 1200/2
1200/2 simplified is 600
C. 65 degrees.
Triangles must equal 180 degrees. The given 50 means the rest of the triangle is equal to 130. I believe because of the Side-Angle-Side theorem of triangles (if my knowledge of proofs from 3 years ago is still with me), the two remaining angles are equal to each other. Let's call them X. 2x = 130. Divide both sides by 2. 130/2 = 65. So x=65
