D because of the distribution property
Answer:
v=18
Step-by-step explanation:
10-3v-1=5(9-v)
first open the bracket
10-3v-1=45-5v
5v-3v=45-9
2v=36
v=18
Answer:
She can only make 5/6 of her recipe with the amount of milk that she has.
Step-by-step explanation:
Some data of this problem is missing, the data missing is:
Her recipe calls for 3/4 of a pint of milk and she only has 5/8 of a pint of milk.
Now, to know what's the portion she can do with that amount we need to divide the amount of milk she has by the total amount she needs:
÷
When we divide we turn the second fraction upside down (the numerator becomes the denominator and viceversa) and multiply, thus:
÷
×![\frac{4}{3} =\frac{20}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%3D%5Cfrac%7B20%7D%7B24%7D)
If we simplify this last expression we have:
![\frac{20}{24}=\frac{10}{12} =\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B24%7D%3D%5Cfrac%7B10%7D%7B12%7D%20%20%3D%5Cfrac%7B5%7D%7B6%7D)
Thus, she can only make 5/6 of her recipe with the amount of milk that she has.
<em>Note: In case the data missing is different, you can apply this same procedure with the fractions you have. </em>
Answer:
x = - ![\frac{9}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B11%7D)
Step-by-step explanation:
Given
- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides
- 8x - 6 = 3x + 3 ( subtract 3x from both sides )
- 11x - 6 = 3 ( add 6 to both sides )
- 11x = 9 ( divide both sides by - 11 )
x = - ![\frac{9}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B11%7D)
Answer:
