Answer:
Expressions are equal to 0 when x = –1 :
1. 4(x+1) : (4x+5)
3. 4(x-(-1) : (4x+5)
5. 4(x+1) : (5-4x)
Hoped I helped
Yoo give me a brainiest
Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>
<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>
<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>
<span>2c = 8 </span>
<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.
Hope this is the answer that you are looking for. Thanks for posting it here in brainly.
To solve this problem, I would set up an equation, letting x represent our unknown value. First, we must convert 12% to its decimal equivalent, by dividing 12/100. We do this because percentages represent parts of a total 100%, so we must take the percentage (part) and divide it by 100 (whole). Since 12/100 = 0.12, we can create our equation:
182 is 12% of a number
*Remember that "is" means equals in math and "of" means multiplication*
182 = 0.12 * x
OR
182 = 0.12x
To solve this equation, we must divide both sides of the equation by 0.12 to get the variable x alone on the right side of the equation.
x = 1516.66666667
Therefore, your answer is option B, 1516.7.
Hope this helps!
