Answer:
b
Step-by-step explanation:
3 : 8....can be written as 3/8
12 lbs of apples were sold
apples / oranges : 3/8 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (12)(8)
3x = 96
x = 96/3
x = 32 <=== 32 lbs of oranges
notice that 3/8 = 12/32....these are equivalent fractions....because that is what proportions are, equivalent fractions
The spent 4.50 individual and 9.50 together and they have 24.50
The rule of the linear equation which is 'y is three more than twice x' can be translated into y = 2x + 3. Thus, we simply use the points and subtitute it to the y and x variables.
1st point: (-1, 1)
1 = 2(-1) + 3
1 = -2 + 3
1=1
2nd point: (0, 3)
3 = 2(0) + 3
3 =3
3rd point: (-1/3, 7/3)
7/3 = 2(-1/3) + 3
7/3 = -2/3 + 3
7/3 = 7/3
All points prove the equation satifsfies the set of coordinates.
