2x-4y=-16
ax+4y=6 +
--------------------
2x+ax=-10; for x=-2,
2(-2)+a(-2)=-10
-2a=-10+4
a=-6/-2
a=3
There are 16 servings for each 128 fluid ounces of juice.
Divide 80 servings by 16 servings, and 5 should be the quotient. Therefore, there are 5 jars of juice. Multiply 128 by 5 since 128 fluid ounces are in one jar. The answer should be 640 fluid ounces.
H + c = 605
c = h + 55
h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday
c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday
Answer:
The correct answer is f) none
Step-by-step explanation:
Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- <em>2 axles - </em><em>.</em>
- <em>3 axles - </em><em>.</em>
- <em>4 axles - </em><em>.</em>
<em />
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e.
<u>(a) 2 axles</u>
The maximum weight, here is 40000.
So, the inequality is:
<u>(b) 3 axles</u>
The maximum weight, here is 60000.
So, the inequality is:
<u>(c) 4 axles</u>
The maximum weight, here is 80000.
So, the inequality is:
