20 hours because 1 mile is 1 hour so 4 miles is 4 hours so if you times the 5 days by the 4 miles/ hours you get 20 hours in 5 days.
B. 1 13/50
we would convert this by doing 126/100 and then simplifying to 1 26/100 and then 1 13/50
We know that:
∠ABC=∠BCA=xº
∠BDC=∠BCD=xº
1) we have to find the angle ∠DBC:
∠BDC+∠BCD+∠DBC=180º
xº+xº+∠DBC=180º
2xº+∠DBC=180º
∠DBC=180º-2xº
2) we have to find the angle ∠ABD:
∠ABD=∠ABC-∠DBC
∠ABD=xº-(180º-2x)
∠ABD=xº-180º+2xº
∠ABD=3xº-180º
Answer: ∠ABD=3xº-180º
1.5 times 7 days in a week is 10.5 cups a week
10.5 divided by 16 cups in a gallon is 0.65625 gallons per week
0.65625 or
gallons per week
Answer:
B and D
Step-by-step explanation:
10x^2 -vx [ has the highest power of X as 2 , so it is to degree 2].
6x^2 - 6x + 5[ has the highest power of x as 2; hence it is to degree 2]
