Martin spends 35 minutes exercising daily. Two equivalent expressions to find his exercise time in 7 days are '7 * 35' and '(7 * 10) + (7 * 25)'. Thus, Martin exercises for a total of 245 minutes in 7 days.
First, let's determine the total amount of time Martin exercises daily. He lifts weights for 10 minutes and runs on the treadmill for 25 minutes. Thus, the total time he spends exercising each day is 10 minutes (weightlifting) + 25 minutes (treadmill) = 35 minutes.
Two equivalent expressions for Martin's total exercise time in 7 days can be represented as:
In both cases, they lead to the same conclusion. Hence, the total time Martin spends exercising in 7 days is 7*35 =245 minutes.

Answer:
x = -30
y = -20
Step-by-step explanation:
x - 12y = 210..... (I)
x - 6y = 90..... (II)
Subtract equation (II) from (I)
- 12y - (-6y) = 210 - 90
-12y + 6y = 120
-6y = 120
Divide through by -6y
Therefore, y = -20
Substitute y = -20 in equation (II)
x -6 (-20) = 90
x + 120 = 90
x = 90 - 120
x = -30

Answer:
2(2x + 4) – 3(x - 1) = 11
4x+8-3x+3=11
4x-3x+8+3=11
x+11=11
x=0
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
Given
2(2x + 4) - 3(x - 1) = 11 ← distribute parenthesis and simplify left side
4x + 8 - 3x + 3 = 11
x + 11 = 11 ( subtract 11 from both sides )
x = 0
Answer:
For plato users is tan(-x)
Step-by-step explanation:
The previous answer is correct but you have to follow the formula they are giving you
So intead of -tan(x) you write tan(-x) just like in the formula
