What are two solutions of 3 + 4 |x/2 + 3| = 11?
Alex
3 + 4abs(x/2 + 3) = 11 Subtract 3
4 abs(x/2 + 3) = 11 - 3
4 abs(x/2 + 3) = 8 Divide by 4
abs(x/2 + 3) = 8/4
abs(x/2 + 3) = 2

Solution 1
x/2 + 3 = 2 Subtract 3
x/2 = 2 - 3
x/2 = - 1 Multiply by 2
x/2 *2 = - 2
x = - 2

Solution 2
x/2 + 3 = - 2
x/2 = - 2 - 3
x/2 = - 5 Multiply by 2
x = -5 * 2
x = -10

Solutions
x = - 2 <<<< answer 1
x = -10 <<<< answer 2

How would you reduce the square root of 12. <br><br> Full sentence
Liula [17]

Answer:

3.4

Step-by-step explanation:

I think that you mean "How do you estimate the square root of 12."

1. √12 is between √9 and √16, which are 3 and 4

2. We know that the square root of 12 is between 3 and 4, and we can estimate to the tenth, getting 3.4

Write three fractions that are equivalent to 3 over 11 , but written in higher terms. One of them must
Alinara [238K]

Answer:

Three fractions that are equivalent to \frac{3}{11} are: \frac{6}{22}, \frac{24}{88} and \frac{144}{528}.

Step-by-step explanation:

Equivalent fractions are set of fractions in which when simplified, they have the same answer.

Given: \frac{3}{11}

i. multiply the numerator and denominator of \frac{3}{11} by 2,

          = \frac{3*2}{11*2} = \frac{6}{22}

i. multiply both the numerator and denominator of \frac{6}{22} by 4,

          = \frac{6*4}{22*4}= \frac{24}{88}

ii. multiply the numerator and denominator of \frac{24}{88} by 6,

          = \frac{24*6}{88*6} = \frac{144}{528}

So that;

             \frac{3}{11} = \frac{6}{22} = \frac{24}{88} = \frac{144}{528}.

Three fractions that are equivalent to \frac{3}{11} are: \frac{6}{22}, \frac{24}{88} and \frac{144}{528}.

I need help!!!!!!!!!!!
Keith_Richards [23]
3. well you know to get the perimeter of a rectangle, you add together 2L and 2W. A way you could write this is-- 2x + 2(x+5). You would just need to simplify it--2x + 2x+10 --4x+10.
4. To find out how much they have in all, you just need to add them together--x+24.50 + 7x-52.34. Now you need to simplify the problem by putting the values together. x+7x + 24.50-52.34-- you can do that.
5. To do this one, look back at 3. and just change the numbers. Drawing a picture may help. The sides are x+y and the top and bottom are 5y+12.
6. same as 5.
7. I think this one is just solving for x first. make Tom and his brother's equations equal to zero and get x by itself. Tom's equation would be 8x-30=0 ----His brother's would be 5x+10. You need to find out what x equals then plug it back into the equations. To plug it in, have x's value take x's place then find the number of candies they have. 
8. The easiest way to start is by writing the same values together. 4x+3x-5x-5-7+2---then just add the x's together and add the numbers together. 
9. Multiply the outer numbers to both of the values in the parentheses. 2(x-4) would turn out to 2x-8. then do the same as 8. and put the same values together to simplify. 
10. get x by itself. Start by multiplying 3 by x and 4 in the parentheses. simplify the numbers then subtract it from both sides to get x alone.
