Answer:
x ≤ 40
Step-by-step explanation:
Pounds of food : number of guinea pigs
1 pound : 5 guinea pigs
8 pounds : x guinea pigs
Where,
x = number of guinea pigs at 8 pounds of food
Inequality:
1 : 5 ≤ 8 : x
1/5 ≤ 8/x
Cross product
1*x ≤ 5*8
x ≤ 40
The solution to the inequality is
x ≤ 40
Answer:
B and C
Step-by-step explanation:
Uses my calculator and put the table in for worker be and thats how i found the slope was 12.5 . then i used to to figure out that when the hour got to 10 worker B starts making more money.
Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.
Answer:
substitute 8 into x =(8-2)2
