Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)
Answer:
-50
Step-by-step explanation:
-32 + ( -18 )
= - 32 - 18
= -50
Hope this helps!
Answer:
D: 14q + 21√qr
Step-by-step explanation:
We want to find the product of;
(2√q + 3√r) and 7√q.
Where p and q are integers.
Using distributive property, we have;
(2√q × 7√q) + (3√r × 7√q)
>> 14q + 21√qr
Correct option is D
a > b
A . a^5b^3/ab^4 = a^4/b
B. a^4 / a*a*a*a = a^4 / a^4 = 1
C. ab^2 / a^2b = b/a
D. b*b*b/b^3 = b^3/b^3 = 1
B and D, doesn't matter what values of a and b it's always equal 1
Lets say a = 2 and b = 1
A. a^4/b = 2^4 / 1 = 16/1 = 16
C. b/a = 1/2 = 0.5
So C has the least value
Answer:
ab^2 / a^2b
Answer:
(8, 11 )
Step-by-step explanation:
Given the 2 equations
2x + 2y = 38 → (1)
y = x + 3 → (2)
Substitute y = x + 3 into (1)
2x + 2(x + 3) = 38 ← distribute and simplify left side
2x + 2x + 6 = 38
4x + 6 = 38 ( subtract 6 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Substitute x = 8 into (2) for corresponding value of y
y = 8 + 3 = 11
Solution is (8, 11 )
