Each day, Martin lifts weights for 10 minutes and runs on the treadmill for 25 minutes. Wrire two equivalent expressions and then find the total minutes that Martin exercises in 7 days.
Answers
Final answer:
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.
Explanation:
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:
- 7 (days) * 35 (minutes/day)
- (7 days * 10 minutes/day) + (7 days * 25 minutes/day)
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:
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

Answers
7 is in the tenths place. This number is read as "seven tenths".
0.7 is converted from 7/10.
Example #2 : 0.13
1 is in the tenths place.
3 is in the hundredths place.
This number is read as "thirteen hundredths"
0.13 is converted from 13/100.
Example #3: 0.157
1 is in the tenths place.
5 is in the hundredths place.
7 is in the thousandths place.
This number is read as "one hundred fifty seven thousandths"
0.157 is converted from 157/1000.
Example # 4: 1.5
1 is in the ones place
5 is in the tenths place.
This number is read as "one and five tenths"
1.5 is converted from 15/10 or 1 5/10.
Example # 5: 25.67
2 is in tens place.
5 is in ones place.
6 is in tenths place
7 is in hundredths place.
This number is read as "twenty-five and sixty seven hundredths"
25.67 is converted from 25 67/100 or 2567/100
