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:
x=4/7
Step-by-step explanation:
Change mixed fractions to improper fractions
2 1/4 = 9/4
1 2/7 =9/7
Therefore, we have
9/4=9/7÷x
9/7÷x is 9/7×1/x=9/7x
Then, we have
9/4=9/7x
Cross multipy
9×7x=9×4
63x=36
Make x the subject of the formula, we have
x=36/63
x=4/7
Answer:
x= 60 y=50
Step-by-step explanation:
First to find x, all the degrees in a triangle add up to 180 degrees. So 50+70+x=180 which is also 120+x=180 which means x=60. Y is the exterior angle of x and a missing angle. Let's substitute the missing angle with the variable z. 60+50+z=180 which is 110+z=180 which means z is 70. So 180-x+z=y. 180-60+70=y which means y is equal to 50. Hope this helps!
Answer:
-100x=-100
x=1
Step-by-step explanation:
(simplifying the equation)
-100x-100=0
-100x=-100 they subtracted -100 from both sides
x=1 then divided by -100
