C. Because each watermelon (m) costs $4. When you multiply 4 and m, the answer cannot be more than $22, hence a less than or equal to sign
Answer:
8 inches
Step-by-step explanation:
We are given: 2L+2W=38 or simplified version: L+W=19
L=3+W
So plug 2nd equation into first, like so, (3+W)+W=19
3+W+W=19
3+2W=19
2W=16
W=8
Base x height divided by 2
Answer:
18/7
Step-by-step explanatiP(x)= -2x^4-4x^3+6x^2-7
This shows that about 7 and 3 pounds of each chocolate were included in the mixture.
Let the number of pounds of both chocolates be x and y.
If Enrico sold a 10-pound box of assorted chocolates, hence;
x + y = 10 ................. 1
If some of the chocolates in the box sold for $1.75 per pound and some sold for $2.00 per pound with mixture sold for $1.90 per pound, then:
1.75x + 2x = 1.90 ................ 2
Solve equations 1 and 2 simultaneously.
x + y = 10 ................. 1 * 20
17.5x + 20x = 19 ................ 2 * 1
____________________________
20x + 20y = 200
17.5x + 20x = 19
Subtract
20x - 17.5x = 200 - 19
2.5x = 181x = 7.24
Substitute 7.24 into 1
x + y = 10
y = 10 - 7.24
x = 2.76
This shows that about 7 and 3 pounds of each chocolate were included in the mixture.
