.2 goes into 7 35 times.
you move the decimal in .2 to make it 2 and make 7 70; 2 goes into 7 3 times which gives you 6 on top and 10 on the bottom, 2 goes into ten 5 times so your final answer would be 35
Answer:
C. 2.0 < t < 2.5
Step-by-step explanation:
Diameter of track (D) = 2 miles, Average rate (A) = 3 miles per hour
A = distance/ time
time (t) = distance/A
distance around the track (circumference) = πD = 3.142 × 2 miles = 6.284 miles
t = 6.284miles/3miles/hour = 2.1 hour
Therefore, 2.0 < t < 2.5
Answer:
a simplified fraction would be 4/10 but not simplified would be 40/100
Step-by-step explanation:
Answer:
T=-13
Step-by-step explanation:
Simplifying
5t + 12 = 4t + -1
Reorder the terms:
12 + 5t = 4t + -1
Reorder the terms:
12 + 5t = -1 + 4t
Solving
12 + 5t = -1 + 4t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-4t' to each side of the equation.
12 + 5t + -4t = -1 + 4t + -4t
Combine like terms: 5t + -4t = 1t
12 + 1t = -1 + 4t + -4t
Combine like terms: 4t + -4t = 0
12 + 1t = -1 + 0
12 + 1t = -1
Add '-12' to each side of the equation.
12 + -12 + 1t = -1 + -12
Combine like terms: 12 + -12 = 0
0 + 1t = -1 + -12
1t = -1 + -12
Combine like terms: -1 + -12 = -13
1t = -13
Divide each side by '1'.
t = -13
Simplifying
t = -13
