If his best time is x, and the best time is smaller, then (1+1/3)*x=his second best time. If x+4=his second best time (since his second best time is 4 seconds slower), then (1+1/3)*x=x+4. Multiplying it out, we get (3/3+1/3)*x=x+4
=4x/3=x+4. Subtracting x from both sides, we get 4x/3-3x/3=x/3=4. Multiplying both sides by 3, we get x=12=his best time
Answer:
4.2 miles
Step-by-step explanation:
6/50=.12
.12*35=4.2 miles
Answer:
y=4x+3
Step-by-step explanation:
The slope of the line is (13-7)/(2-1)=4. The line equation is hence y=4x+3
C. The temperature increased 14 degrees.
I just learned that a rhombus has equal opposite equal acute angles, opposite equal obtuse angles, and four equal sides. That means y is equal to all the sides! Angle x is 61° and y = 16 in
