Answer:
distance covered in 2 hours = 80 km
distance covered in 1 hour = 80÷2 = 40 km
distance covered in 7/2 hours = 40 × 7/2
= 140 km
(3 1/2hours = 7/2 hours)
Answer:
The correct option is B
i just answer that on our test and i got A+

Answer:
see explanation
Step-by-step explanation:
Alternate exterior angles are congruent, thus
∠ RST = ∠ RQP , substitute values
7x + 11 = 4x + 32 ( subtract 4x from both sides )
3x + 11 = 32 ( subtract 11 from both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Thus
∠ RST = 7(7) + 11 = 49 + 11 = 60°
∠ RQP = 4(7) + 32 = 28 + 32 = 60°
Hey there!
If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.
20% is the same as 1/5 of the total amount, since there are 5 20s in 100.
So, we can simply multiply 4 by 5 to get the total amount of problems.
4 x 5 = 20
This means there were 20 problems on the test.
Hope this helps!
