Answer:
9 11/12
Step-by-step explanation:
Solve 7 2/3-1 2/4+3 6/8
We are to the above fractions
7 2/3 - 1 2/4 + 3 6/8
The Lowest Common Denominator = 24
(7 - 1 + 3) + ( 2/3 - 2/4 + 6/8)
9 + (16 - 12 + 18/24)
9 + 22/24
9 11/12
Answer:
x > or equal to 9.7
Step-by-step explanation:
Don't let the inequality intimidate you. Treat the > or equal sign like it is an equal sign.
Any thing you do on the right you must do on the left.
move 3 to other side
combine like terms
15x > or equal to 145.5
Divide both sides by 15
x > or equal to 9.7
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
Answer:
To run one lap Lin takes 1.6 minutes.
Step-by-step explanation:
To find this answer you would do 8 divided by 5. Always remember when dividing time goes first unless the instructions / directions / your teacher says differently. So, when you do 8 divided by 5 the answer you get is 1.6, and there is your answer. Also to check your answer you can do 1.6 times 5, and you get 8, so you know that 1.6 is the correct answer.
