-1/2x+3=-x+7
Multiply throughout by 2x
-1+6x=-2x^2+14x
2x^2-8x-1=0
3 students = $48.76
1 student = 48.76 ÷ 3 = $16.25 (nearest hundredth)
Answer:
a= infinite
b= one sol
c= no solutions
d= infinite
Step-by-step explanation:
I how this helped. Basically solve for X and see if you can. If you can't it is zero solutions, if you can solve it one way then it is one solution, and if will will always solve then it is infinite solutions.
#3 is $25.98 because first you multiply 24 by 8.25% which equal 1.98 and then add 24 and 1.98 which equal $25.98
Answer:
56.6in³
Step-by-step explanation:
volume of a pyramid = 1/3 x Area of base x height
1/3 x 11.1 x 15.3 = 56.61 in³
56.6 in³ to the nearest tenth
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the hundredth term is 1 which is less than 5. O is added to 6
