Answer:
are those 3 different question of just one?
Step-by-step explanation:
Answer: (2,2), (4,2)
First, I subtracted 2y from both sides of the second equation. Then, I substituted -2y+6 in for x in the first equation (-2y+6)²+4y²=20. Then, I expanded 4y²-24y+16+4y²=20. Next, I combined like terms, and moved everything to one side 8y²-24y+16=0. Then, I factored out an 8, and then finished factoring 8(y-2)(y-1). This gives me my y-values, y=1,2. Next, I inserted each y-value into the second equation and got x=-2(1)+6 ---> x=4 (The first solution is (4,1). ) and x=-2(2)+6----->x=2 (The second solution is (2,2).
In number form, 5,004,300
5:12 means there are 17 parts
Percentages are calculated by dividing the part by the total, and multiplying by 100
Julie put in 5 out of 17 parts so:

×100=29.4%
Kristen owns the rest of the business

×100=70.6%
The amount of money doesn't make a difference, as the percentage will always be the same.
Answer:
a = 81.5
b = 98.5
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
a = x-3
b = x+14
In supplementary angles , the formula are as follows,
a + b = 180
By putting the value, we get
x - 3 + x + 14 = 180
2x + 11 = 180
2x = 180 - 11
2x = 169
x = 169 ÷ 2
x = 84.5
So, a = 84.5 - 3
= 81.5
b = 84.5 + 14
= 98.5
