120/4 = 30
120 x 2 = 240
240 + 30 = 270
270 grams of flour were used
The correct answer is y = 1/8x^2
Answer:
5 5/7
Step-by-step explanation:
-4*6/7*-5/3
We can multiply the numerators
-4 * 6*-5 = 120
We can multiply the denominators
7*3 =21
Put the numerator over the denominator
120/21
The top and bottom are both divisible by 3
120/3 = 40
21/3 =7
The new improper fraction is 40 /7
Changing from an improper fraction to a mixed number
7 goes into 40 5 times with 5 left over
5 5/7
Answer:
202.9 cm^3
Step-by-step explanation:
Mass is 712.04 grams
Density is 3.51 grams/cm^3
Volume = (712.04 g)/(3.51 grams/cm^3) = 202.9 cm^3
First equation 2(4X -5y = 4)
8X -10y = 8
Elimination 8x -10y =8
-8x + 9y =-8
-y =0
-1(-y =0)
y =0
8x -10(0) =8
8x =8
(8x =8)/8
x = 1
