Answer:
<u>x = -8</u>
4x + 8 = 2x - 8
3x + 4 = 2x - 4
2x + 16 = x + 8
x - 1 = 2x + 7
17x + 36 = 16x + 28
13x + 2 = 12x + 11
.......
(this is infinite)
As long as it cancels out to x = -8
Answer:
the third one is the correct answer
Answer:
3 11/16 pounds
Step-by-step explanation:
Lynne bought a bag of grapefruit, 1 5/8 pounds of apples, and 2 3/16 pounds of bananas. The total weight of her purchases was 7 1/2 pounds. How much did the bag of grapefruit weigh?'
The Total weight = Weight of grape fruits + Weight of Apples + Weight of Bananas
Let the weight of the grape fruit = x
7 1/2 = x + 1 5/8 + 2 3/16
x = 7 1/2 - (1 5/8 + 2 3/16)
Lowest Common Denominator = 16
x= 7 1/2 - 3 + ( 10+ 3/16)
x = 7 1/2 - 3 + (13/16)
x = 7 1/2 - 3 13/16
Lowest Common Denominator = 16
x= 4 (8 - 13/16)
x = 4 (-5/16)
x = 3 11/16 pounds
Therefore, the bag of grapefruits weighed 3 11/16 pounds
Your answer is 0.8 or 80%
Explanation:
Consider the ratio written like a fraction:
<span><span>Count of sandwichescount of people</span>→<span>46</span></span>
But we need the count of sandwiches for 1 person. So we need to change the 6 people into 1 person. To change 6 into 1 divide it by 6
<span>6÷6=1</span>
For ratios, when multiplying or dividing, what we do to the bottomwe do to the top.
So to change <span>46</span> into what we want we apply
<span><span><span>4÷6</span><span>6÷6</span></span>=<span><span>23</span>1</span>← <span>Count of sandwichescount of people</span></span>
So each person ends up with <span>23</span> of a sandwich
<span>Now see where the shortcut comes from <span>46</span>=<span>23</span><span> of a sandwich</span></span>
Answer is false. the slope is 1 because x equals one. the one is hidden but it is next to x
