For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)
For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600
Sum of first 120 positive integers = s + s + 3600 = 2s + 3600
1cm³=1mL
1942cm=x mL
1cm³ 1942cm³
________ = ________
1mL x mL
Cross multiply
1x=1942
divide both sides by 1
x=1942mL
Answer=1942mL
48 = -18x is an equivalent expression because you just subtact -18 from both sides.
Answer:
y+2≥5(≥ we don't need the_ because i can't find the symbols)
Step-by-step explanation:
To find out how much a 60% discount for a wagon that is $229.50, you will have to figure out how to find the discount. First we will find the discount.
229.50 × 0.60 = 137.70
Now, you will subtract that number from the original price
229.50 - 137.70 = 91.80
Now after the discount of 60% the wagon is now $91.80
