18. part 1) x equals 4d square root 5 over 5 . it's a fraction
part 2) x equals 4 square root 5 over d. it's a fraction
part 3) x equals d square root 5 over 4. it's a fraction
part 4) x equals 4d square root 5 over 5 (same as part 1)
ASA = Angle Side Angle so you need a pair of triangles that give you 2 angles and 1 side
the correct answer would be B
Answer:
Option A = 75 is the best option
Step-by-step explanation:
It took Ashlie 2.5 hours (11:30 am - 2pm) to assemble the marketing packets
Rate = Number of jobs done/Time taken = 90 packages/hr
Number of jobs done = Rate * Time taken = 90 * 2.5 = 225 packages.
Dwayne has assembled the same number of packages = 225 (as reported in the question),
It took Ashlie 2.5 hours (11 am - 2pm)
Then, his work rate is calculated as: Number of jobs done/Time taken = 225 packages/3 hours = 75
Thus, option A = 75 is the best option
Twenty-eight and five-sevenths. 28 5/7
Answer:

Step-by-step explanation:
1) if to re-write the given equation into slope-interception form, then:

the slope of the given line is 5/2;
2) according to the rule of perpendicular, the required slope should be:
s*(5/2)=-1;
3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.
