Let a be the amount of peanuts; and
Let b the amount of walnuts
Equation 1 would be: A + B = 100
249a + 389b = 319 (100)
Equation 2 would be: 249a + 389b = 31900
From equation 1:
a = 100 – b
249 (100 – b) + 389b = 31900
24900 – 249b + 389b = 31900
140b = 7000
b = 50 lbs
then from equation 1:
A + 50 = 100
A = 50 pounds
Answer:Let
x-----------> the number
we know that
The expression "the difference between five times a number and twice that number" is equal to
5x-2x
therefore
the answer is
5x-2x
A common denominator is 30
Answer:
Well then...
Step-by-step explanation:
X= small angle
x+50= larger angle
supplementary angles=180 degrees
x+x+50= 180
combine like terms
2x+50=180
subtract 50
2x= 130
divide by 2
x= 65 degrees for the smaller angle
115 degrees for the larger
hope this helps
