Answer:
a = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
When working with fractions, I would mostly like to make the denominators the same first.
[tex]\frac{2}{3}[/tex]a - [tex]\frac{1}{6}[/tex] = [tex]\frac{1}{3}[/tex]
Make all the denominators 6.
[tex]\frac{4}{6}[/tex]a - [tex]\frac{1}{6}[/tex] = [tex]\frac{2}{6}[/tex]
Isolate [tex]\frac{4}{6}[/tex]a.
[tex]\frac{4}{6}[/tex]a = [tex]\frac{2}{6}[/tex] + [tex]\frac{1}{6}[/tex]
= [tex]\frac{3}{6}[/tex]
Find a.
[tex]\frac{6}{6}[/tex]a = [tex]\frac{6}{4}[/tex] × [tex]\frac{3}{6}[/tex]
a = [tex]\frac{3}{4}[/tex]
If a driver uses 1/ 10 of gas every day what fraction of a tank will he use in 1 week
The fraction of gas the driver use in one week is 7/10 of a tank.
Fraction of gas the driver use in one weekA fraction is a number which has a numerator and a denominator. such as 7/10
Numerator refers to the upper or top value. 7 is the numerator.
Denominator refers to lower or bottom value. 10 is the denominator.
Fraction of gas used in a day = 1/10Number of days in a week = 7 daysFraction of gas the driver use in one week = Fraction of gas used in a day × Number of days in a week
= 1/10 × 7
= (1 × 7) / 10
= 7/10 of a tank
Therefore, the fraction of gas the driver use in one week is 7/10 of a tank.

A number line will be helpful to compare the two of the given terms. The correct option is B, -8.9 > -9.3.
What is a number line?A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.
The two of the given numbers can be compared as shown below.
-8.9 > -9.3
This is because on a number line, numbers on left are of less value than numbers on the right. And since -8.9 is close to 0, then -9.3.
Hence, the correct option is B, -8.9 > -9.3.

Step-by-step explanation:

48÷8=6
this is correct :)
Answer:
x=7
Step-by-step explanation:
-8x+4=-52
First remove the four by subtracting 4 from -52
-8x= -56
Then, you would want the variable (x) by itself, so you divide by -8 (Dividing a negative by a negative makes a positive)
x=7
To confirm this answer is right, plug in 7 as the variable and make sure you get -52
(-8*7)+4= (-52)

Step-by-step explanation:
For the experiment of rolling an ordinary pair of dice, find the probability that the sum will be less than 3 or greater than 5.
According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.
What is Probability?Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability.
According to the given information:When two dice are rolled, the total number of possible outcomes is 36.
sum possibilities probability(favorable/ total outcomes of the event)
2 (1,1) 1/36
3 (1,2) , (2,1) 2/36
4 (2,2), (3,1) , (1,3) 3/36
5 (4,1), (1,4),(2,3),(3,2) 4/36
6 (1,5),(5,1),(2,4),(4,2),(3,3) 5/36
7 (2,5),(5,2)(1,6),(6,1),(3,4),(4,3) 6/36
8 (2,6),(6,2), (5,3),(3,5),(4,4) 5/36
9 (3,6),(6,3),(5,4),(4,5) 4/36
10 (5,5),(4,6),(6,4) 3/36
11 (6,5),(5,6) 2/36
12 (6,6) 1/36
probability that the sum will be less than 3 or greater than 5 = probability for the sum to be 2 + probability for the sum to be 6 + probability for the sum to be 7 + probability for the sum to be 8 + probability for the sum to be 9 + probability for the sum to be 10 + probability for the sum to be 11 + probability for the sum to be 12.
= (1/36) + (5/36) + (6/36) + (5/36) + (4/36) + (3/36) + (2/36) + (1/36)
= (1 + 5 + 6 + 5 + 4 + 3 + 2 + 1)/36
= 27/36
According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.

What is the value of x in the equation? 6(x +1) -5x = 8 + 2(x - 1) *
Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )
6x + 6 - 5x = 8 + 2x - 2
-x = 0
x = 0
Answer:
x = 0
Step-by-step explanation:
First distribute both sides to simplify the equation
6(x +1) -5x = 8 + 2(x - 1) =
6x + 6 - 5x = 8 + 2x - 2
Combine like terms
x + 6 = 6 + 2x
Subtract x from both sides
6 = 6 + x
Subtract 6 from both sides
0 = x

Gasoline costs 1.05 euro per liter in France. What is the price in dollars per gallon?
The price in dollars per gallon is 4.02 dollars per gallons.
How to find the price of gasoline in dollars per gallon?Gasoline costs 1.05 euro per litre in France.
The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.
Then, equate it the quantity of litres to gallons.
