Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
Answer:
7.46 miles she has traveled from her house to the goal.
Step-by-step explanation:
total distance traveled = 1 3/4+ 2 1/3+ 3 3/8 miles
=7/4 + 7/3+ 27/8 ( converting the mixed numbers into improper functions)
= 7(6) +7(8) +27(3)/24 (taking LCM)
=42 +56+ 81/24 (adding)
= 179/24
= 7.46 miles
Answer:
Devin will need 9 cubes of wax.
Step-by-step explanation:
To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.
Once you get 8.4375 cubes, you round to the next whole number, which is nine.
I think it’s -4/1 10, -4.8, -17/4 , 10 if ten wasn’t apart of -4/1 10 sorry if it’s not :/
