Which sentence matches the mathematical equation? p-0.40p=0.60p
IRISSAK [1]
P-0.40p = 0.60p

C. Decrease by 40% is the same as multiply by 60%.

Assume that p = 10

10 - 0.40(10) = 0.60(10)
10 - 4 = 6
6 = 6

Based on the above assumption. 40% of 10 is 4 ; and 60% of 10 is 6. So, 10 less 4(40% of 10) is equal to 6 (60% of 10). 

Percentage is used because 0.40 and 0.60 will be multiplied with 100% to get the equivalent percentage 0.40 x 100% = 40% ; 0.60 x 100% = 60%

Answer:

The Average Temperature for the week is -1°C

Step-by-step explanation:

First to find the average, you have to combine all the numbers

-3-4+0-2+0+3-1 = -7

Then you have to divide the total, with the number of numbers used to combine to make the total

-7 ÷ 7 = -1

The average temperature is -1°C

Solve for aaa: a-\left(-3.75\right)=6.11a−(−3.75)=6.11a, minus, left parenthesis, minus, 3, point, 75, right parenthesis, equals
Ganezh [65]

Answer:

Step-by-step explanation:

                              To isolate <em>a</em>, we add -3.75 to both sides.

                                              <em>a</em>-(-3.75)=6.11

                                   <em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>

                                                           <em>a</em>=6.11<em><u>+(-3.75)</u></em>   Simplifying, we get:  

<em>a</em>=2.36
