5. -6/7 < -5/6

6. 3/10 + (-7/10) = -4/10= -2/5

7. -4/9 - 1/9 = -5/9

Answer:

1/8 will be 0.125 as a decimal so that is greater than 0.12! so it will be this $1.8 \geq 0.12$

Answer:

First one is 25/2

Step-by-step explanation:

12×2+1=25/2

9×4+1=36/4

cross multiply and you get

100/

divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore

(ASAP NEED TO SUBMIT NOW!!!) What is the Unit Rate for each cyclist?

sveta [45]

Answer:

Unit rates for cyclist A , B, C , D are 12 mile/ hour , 5 mile/hour, 9 mile/hour and 10 mile/hour respectively. Cyclist A is the fastest among the four.

Step-by-step explanation:

Cyclist A can ride 24 miles in 2 hours

so, cyclist A's unit rate is, $\frac {24}{2}$

= 12 mile/hour

Cyclist B's unit rate is, $\frac {5}{1}$

= $\frac {10}{2}$

= $\frac {15}{3}$

= 5 mile/hour

Equation for cyclist C is, y = 9x ,

so, cyclist C's unit rate is , 9 mile/hour

Slope of the graph for cyclist D,

= $\frac {10 -0}{1 - 0}$

= 10

So cyclist D's unit rate is, 10 mile/hour

So, cyclist A is the fastest.

Jack charges $40 initial fee plus $30 an hour to work on vehicles. Mark charges $25 an hour with a $50 initial fee. to work on v

Nostrana [21]

Answer:

Step-by-step explanation:

Let the equal number of hours be represented by variable H;

The two equations will be as follows;

Jack; 40 +30H

Mark; 50 +25H

Next, equate them;

40 + 30H = 50 + 25H

30H - 25H = 50 - 40

5H = 10

H =10/5

H = 2hrs

Therefore, they charge the same amount at 2 hrs.

B.) The amount charged;

Replace the variable H in any of the two equations above with 2 to solve for the amount.

Equation 40+30H = 40 + (30*2)

=40 + 60

= $100

Adding mixed numbers. Can someone help me correct my answer?

Olin [163]

Answer:

27 13/60

Step-by-step explanation:

What you have tried to do is not an impossible way to do it. What you could do is set your fractions and whole numbers like this.

( 7 + 1/10) * (3 + 5/6) I don't know if you know what FOIL is, but that is the way to proceed.

First: (meaning the first in each factor ). 3 * 7 = 21
Outside: (meaning the two terms near outside the brackets) 7 * 5/6 = 5 5/6
Inside: The two terms closest to the * sign 1 / 10 *3 = 3/10
Last: The two end terms (1/10 * 5/6 = 5/60 5/60

Now you can add. 21 + 5 is the whole number amount = 26

Add the fractions

5/6 + 3/10 + 5/60 The lowest common multiple is 60
50/60 + 18/60 +5/60 = 73 / 60 = 1 and 13/60

Add that to 26 and you get 27 13/60
