Answer:
[tex]1\frac{19}{30}[/tex]
Step-by-step explanation:
To operate between mixed numbers is always better to write then in fraction form first (as improper fractions), and then operate using the rules to combine fractions.
For the first mixed number :
[tex]4\frac{5}{6} = 4+\frac{5}{6} =\frac{24}{6} +\frac{5}{6}=\frac{29}{6}[/tex]
For the second mixed number:
[tex]3\frac{1}{5} =3+\frac{1}{5}=\frac{15}{5}+\frac{1}{5}=\frac{16}{5}[/tex]
So now we have to subtract these two fractions, so we need to write them with the same common denominator (6 x 5 = 30):
[tex]\frac{29}{6}-\frac{16}{5}=\frac{145}{30} -\frac{96}{30}=\frac{49}{30}[/tex]
and finally we write the obtained answer in mixed number form:
[tex]\frac{49}{30} =1+\frac{19}{30} =1\frac{19}{30}[/tex]

Answer:
x = -19
Step-by-step explanation:
For this problem, we simply need to get rid of the fractions so we can easily solve for x.
To get rid of these fractions, we will multiply the whole equation by the LCD which is 2 * 3 = 6.
( x / 2) - ( 1 / 2) = ( 2x / 3) + ( 8 / 3 )
6 * ( x / 2) - 6 * ( 1 / 2) = 6 * (2x / 3) + 6 * ( 8 / 3 )
3x - 3 = 4x + 16
3x - 3x - 3 - 16 = 4x - 3x + 16 - 16
0x - 19 = x + 0
x = - 19
Thus, for the equation to be true, x must be equal to negative 19.
Cheers.
Answer:
Answer= -19
Step-by-step explanation:
x/2 - 1/2 = 2x/3 + 8/3
x-1 / 2 = 2x+8 / 3
(x - 1) × 3 = (2x + 8) × 2
3x - 3 = 4x + 16
3x - 4x = 16 + 3
-x = 19
x = -19.
Thus, the value of x will be -19.

xavier climbs 9 feet up into an apple tree. what integer represents the direction and how far he will climb to get back down to the ground? what does the integer 0 represent in the situation? the integer _______ represents Xavier's climb down. the integer 0 represents _____________. how are the absolute vales of opposite integers related?
PLEASE HELP!!!!!
Answers
Answer:
1. 9 feet
2. The ground
3. Absolute values of opposite numbers are the same
Step-by-step explanation:
Given
Distance up the apple tree = 9 feet up
Solving (a): How far he'll climb to come down
In this case, the distance from the ground up to the tree is the same distance back to the ground.
In other words;
Since he climbs 9 feet up, then he'll climb 9 feet down to the ground
Solving (b): What 0 represents
In this case, 0 represents the ground
Solving (c): Absolute values
The absolute values of opposite numbers (from negative to positive) are the same
Take for instance:
[tex]|-9| = 9[/tex]
[tex]|-3| = 3[/tex]

Oy - 8 + x
O y = 1/(8x)
O y=8
O y = 8x
Answers
Answer:
y=8x
Step-by-step explanation:
There is no why intercept because there is no additional boarding fee, so the only part of the equation you get is y=mx. In this equation, that is y=8x, where "x" is the number of hours in the cab, 8 represents the cost per hour, and "y" is the total cost of the entire cab ride.

Answer:

Step-by-step explanation:
To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.
Numerator: 12 - 6 + 5 * (-3)^2
= 12 - 6 + 5 * (9)
= 12 - 6 + 45
= 6 + 45
= 51
Denominator: 17
So our simplified fraction is as follows:
51/17
Which can be reduced to the whole number, 3.

There are 360 degrees in a circle.
Thus, if a circle turns x degrees, then it will represent x/360 of the entire circle.

Li uses 8.4 grams of sugar every day in her tea. Sue uses 12.6 grams of sugar every day in her coffee. If Li’s sugar canister contains 128 grams of sugar and Sue’s canister contains 191 grams, in how many days will Li and Sue have the same amount of sugar in their canisters?
Answers
Answer:
15 days
Step-by-step explanation:
a) Li uses = 8.4 grams of sugar every day in her tea.
Li’s sugar canister contains = 128 grams of sugar
Let x be the number of days at which Li uses sugar in her tea
The Equation for Li's sugar usuage =
y = 128 - 8.4x ......... Equation 1
Where y , the quantity of sugar left.
b) Sue uses = 12.6 grams of sugar every day in her coffee.
Sue’s canister contains = 191 grams
Let x be the number of days at which Sue uses sugar in her tea
The Equation for Sue's sugar usuage =
y = 191 - 12.6x .........Equation 2
Where y , the quantity of sugar left.
We are asked in the question, how many days will Li and Sue have the same amount of sugar in their canisters
We would equate both equations to each other.
Equation 1 = Equation 2
y = 128 - 8.4x = y = 191 - 12.6x
128 - 8.4x = 191 - 12.6x
-8.4x + 12.6x = 191 - 128
4.2x = 63
x = 63/4.2
x = 15
15 days
Therefore Li and Sue have the same amount of sugar in their canisters after 15 days.
To confirm
Equation 1 = Equation 2
y = 128 - 8.4x = y = 196 - 12.6 × 15
y = 128 - 8.4 × 15 = y = 196 - 12.6 × 15
y = 128 - 126 = y = 196 - 189
y = 2 = y = 2
