Answer:
Step-by-step explanation:
d = - 9
a = 4
n = 95
tn = a + (n - 1)*d
t95 = 4 + (94)*(-9)
t95 = 4 -846
t95 = - 842
Answer:
29
Step-by-step explanation:
9 + 20
2 0
+ 9
2 9
Answer:
Step-by-step explanation:
I hope that you don't have to multiply this out. If you do, leave a note. I delete my answer.
y = (x + 20)(x+16)(x + 11)(x + 9)
One piece will be length x and the other piece will be 20 cm longer, so it will be x + 20 cm long.
Added together the length of these two boards will equal 86 cm. So you can write an equation:
x + (x + 20) = 86
Remove the parentheses and add the two x's together to get:
2x + 20 = 86
Subtract 20 from both sides:
2x = 66
Divide both sides by 2 and you have:
x = 33
The short piece is 33 cm and the other piece is 20 cm longer or 33 + 20 = 53 cm.
You have to add these together to find the total number of quarts she made. 8+5+5= 18 quarts of soup. if everyone gets one cup, then 18 people is able to get soup. the answer is 18 guests
