Hi,
x + y = 350 (equation 1)
3x + 2y = 950 (equation 2)
Use Substitution Method
Isolate variable x in equation 1
x = 350 – y (equation 3)
Substitute equation 3 into equation 2
3(350 – y) + 2y = 950
1050 – 3y + 2y = 950
3y – 2y = 1050 – 950
y = 100
Substitute y = 100 into equation 1
x + 100 = 350
x = 250

Answer:
9^8
Step-by-step explanation:
9²•9⁶ = 9^(2+6) = 9^8
First, find the volume of the whole cube
Volume of cube = 4 x 4 x 4 = 64 cm³
The volume of sand is 25% of the volume of cube so,
Volume of sand = 25/100 x 64 = 16 cm³
