Answer: you bought 9 burgers and 16 tacos
Step-by-step explanation:
Let x represent the number of burgers that you bought.
Let y represent the number of tacos that you bought.
You buy a total of 25 burgers and tacos. It means that
x + y = 25
The burgers cost $3.50 each and the tacos cost $2.25 each. The total cost of the burgers and tacos that you bought is $67.50. It means that
3.5x + 2.25y = 67.5- - - - - - - - - - - - 1
Substituting x = 25 - y into 1, it becomes
3.5(25 - y) + 2.25y = 67.5
87.5 - 3.5y + 2.25y = 67.5
- 3.5y + 2.25y = 67.5 - 87.5
- 1.25y = - 20
y = - 20/ - 1.25
y = 16
x = 25 - y = 25 - 16
x = 9

The given circle has center:
(11,5)
and
radius: 4
The equation of a circle with center (h,k) and radius , r is given in standard form as;
We substitute the values into the formula to obtain,
Answer:
Step-by-step explanation:
so there is 32 kids....1/2 are blonde, 1/4 have black hair, 1/4 have brown hair
1/2(32) = 32/2 = 16 are blonde
1/4(32) = 32/4 = 8 have black hair
1/4(32) = 32/4 = 8 have brown hair
