Answer:
4 gallons per gift basket
Step-by-step explanation:
20 x 4 = 80
Answer:
91
Step-by-step explanation:
Let
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
Total = 182
x + x + 1 + x + 2 + x + 3 = 182
4x + 6 = 182
Subtract 6 from both sides
4x + 6 - 6 = 182 - 6
4x = 176
Divide both sides by 4
x = 176 / 4
= 44
x = 44
x = 44
x+1 = 44 + 1 = 45
x+2 = 44 + 2 = 46
x+3 = 44 + 3 = 47
Sum of the two middle numbers = 45 + 46
= 91

Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is th of the total time.
Hence, option D is correct.
Adding 7x to both sides makes the most sense. It would cancel out with the -7x, leaving you with -5 = 8x + 3.
Subtracting 5 from both sides wouldn't cancel anything out, adding x to both sides wouldn't cancel anything out, and you can't combine like terms on either side of the equation.
