39-23= 16. Mary ran 16 miles
Answer:
y = x + 53
Step-by-step explanation:
Let x be the number of flowers Jamal planted and y the number of flowers Heidi planted.
Jamal planted 53 fewer flowers than Heidi:
x = y - 53
Isolate the y.
x + 53 = y (Change the - sign to + sign when switching from different sides of an equation)
y = x + 53
Answer:
1.75 or 7/4
Step-by-step explanation:
To solve this problem, you would multiple 5 * 7 the divide that by 20.
5 * 7 = 35
Since 35 cannot be divided by 20, the answer will either be a decimal or a fraction, whichever way you decide to write your answer.
The answer you are looking for is 48d^8r^4.
To simplify this answer, you multiply the whole numbers and add the exponents for the like variables. So, multiply 8 and 6 to get 48, and add ^5 to ^3 to get ^8. Thus making the answer 48d^8r^4.
I hope this helps!
