Answer:

Step-by-step explanation:
when the exponent is equal, we can put the x and y together in a bracket and a as the Exponent of xy.
Hope I get your question~
I think the answer is 10 because:
6x2=12
12+2x-32=0
make the like terms together = 12-32+2x=0
= -20+2x=0
again make the like terms together = 2x=0+20 [sign changes when it goes to the other side]
so, 2x=20
x=20/2 [ multiplication will change into division when it goes to the other side]
therefore x=10
Answer:
the circumfrence is at lease 2.19 decimals
Step-by-step explanation:
3x - 14y = 92x use the circumfrence of the circle which is pi 3.14
Answer:
Number of volleyballs bought = 8
Number of basketballs bought = 11
Step-by-step explanation:
Given that:
Total amount spent = $204.20
Let,
x be the number of volleyballs
y be the number of basketballs
According to given statement;
y = x+3 Eqn 1
8.20x+12.60y=204.20 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
8.20x + 12.60(x+3) = 204.20
8.20x + 12.60x + 37.80 = 204.20
20.80x = 204.20 - 37.80
20.80x = 166.40
Dividing both sides by 20.80

Putting x=8 in Eqn 1
y = 8+3 = 11
Hence,
Number of volleyballs bought = 8
Number of basketballs bought = 11
To find the measure of the third angle you should keep in mind the following:
The sum of the three interior angles of a triangle is 180 °.
We have then
k + 27 + 10 = 180
Clearing k:
k = 180-27-10 = 143
K = 143 °
Answer:
the value of k is 143 °
