Answer:
30 centimeters
Step-by-step explanation:
since the width is 4 centimeters more than 3/10 of the length, then 13 is 4 centimeters more than 3/10 of the length. 4 less than 13 is 9, so nine is 3/10 of the length. if 9 is 3/10, then 3 is 1/10 because 3/10 is three times 1/10. If 3 is 1/10, that means that 30 is the length because 1/10 multiplied by 10 is 10 tenths, or 1.
Since it's 0.6 kg for 5 gallons, we'd want to find the unit rate aka the amount of kg's per gallon. To find that, we have to see how many times 5 goes into 0.6, which is 0.6/5=0.12 for 1 gallon. Multiply that by 7 to get 0.84 for 7 gallons!
Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)
Okkkk......what’s the question?
