Answer:
26.4 pounds
Step-by-step explanation:
The question is only asking for weight, therefore the money spent is irrelevant to us. Add just the weights and there's your answer :)
16+10.4=26.4
<span>4x + 5 = 21
4x = 21 - 5
4x = 16
x =16/4
x =4</span>
Answer:
Devante is 23 and Savannah is 32.
Step-by-step explanation:
We can set up a system of equations.
s - savannah's age
d - devante's age
s = d + 9
s + d = 53
Now we can substitute (d + 9) for s in the second equation.
(d + 9) + d = 53
2d + 9 = 53
2d = 46
<u>d = 23</u>
To find Savannah's age, we just add 9 to Devante's age. (plugging in 23 for d)
23 + 9 = 32
<u>s = 32</u>
Answer:
You can use a ratio to solve this problem. Use x as a variable for the cups of food in 28 days.
1 (day): 3 (cups)
28 (days): x (cups)
Cross multiply.
x=28(3)
x=84
So, Li’s dog eats 84 cups of food in 28 days.
