Question
Evaluate.
−[−1 1/5÷0.6(1.3)]−5/6
What is the value of the expression?
Enter your answer as a simplified mixed number in the box.
Answer:
−[−1 1/5 ÷ 0.6(1.3)] − 5/6
First, let's simplify the expression within the square brackets:
−1 1/5 ÷ 0.6(1.3)
To simplify this, let's convert the mixed number to an improper fraction:
−6/5 ÷ 0.6(1.3)
Next, we multiply 0.6 by 1.3:
−6/5 ÷ 0.78
To divide fractions, we can multiply by the reciprocal:
−6/5 * (1/0.78)
Now, let's multiply the numerators and denominators:
-6/5 * 1/0.78 = -6/5 * 1/0.78 = -6/3.9
To simplify this fraction, we can multiply both the numerator and denominator by 10 to eliminate the decimal:
-6/3.9 * 10/10 = -60/39
Now, let's simplify the expression further:
−60/39 − 5/6
To add or subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 39 and 6 is 78:
−60/39 − 5/6 = −(60/39 * 2/2) − 5/6 = −120/78 − 5/6
Now, we can combine the fractions:
−120/78 − 5/6 = (−120 * 6)/(78 * 6) − 5/6 = −720/468 − 5/6
To subtract the fractions, we need a common denominator:
−720/468 − 5/6 = −720/468 − (5 * 78)/(6 * 78) = −720/468 − 390/468
Now, we can combine the fractions:
−720/468 − 390/468 = (−720 − 390)/468 = −1110/468
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 78:
−1110/468 = (−1110 ÷ 78)/(468 ÷ 78) = −15/6
The simplified fraction is −15/6.
However, the question asks for the value as a simplified mixed number. To convert the fraction to a mixed number, we divide the numerator by the denominator:
−15 ÷ 6 = −2 remainder 3
Therefore, the value of the expression is -2 3/6, which can be further simplified as -2 1/2.
So, the value of the expression is -2 1/2.

Write down the equation of the line in slope-intercept form. Underline the slope and circle the y-intercept in each equation.
4y=-6+4x
The slope-intercept form =
The slope =
The y-intercept =
Answer:
The slope-intercept form = y=x-3/2
The slope = 1
The y-intercept = -3/2
Step-by-step explanation:
4y=-6+4x
Turn 4y=-6+4x into slope-intercept form.
4y=-6+4x Divide 4 from each
4y/4=-6/4+4x/4
y=-3/2+x
Since the slope-intercept form is y=mx+b
y=x-3/2
Hope this helps :)
677x74 (show your work) I NEED help ASAP thank you
Answer:50,098
Step-by-step explanation:
(4x7)+(4x70)+(4x600)=2708
(70x7)+(70x70)+(70x600)=47,390
Add=50,098
677 x 70 = 47390
677 x 4 = 2708
47390 + 2708 = 50098
677 x 74 = 50098

What is the product of 5 and 1/3? Write your answer in simplest form.
1. 15
2. 1/15
3. 15/3
4. 1 2/3
Answer: 1 2/3
Step-by-step explanation:
To find the product of fractions, you multiply the denominator and the numerator. 5 isn't a fraction so you can make it a fraction by keeping 1 as the denominator. So 5 as a fraction is 5/1. 5/1 times 1/3 = 5/3. 5/3 as a mixed number is 1 2/3.

The veterinarian told Sally that her cat needs to lose 5 pounds. A healthy weight loss for her cat would be about 1 pound every 2 weeks. To model this situation, she graphed the following line, where y represents the number of pounds left to lose and x represents time in weeks.
The equation for this line is y =___ x + ___ . If she continues the line, she would see that it would take___weeks for her cat to lose 5 pounds
Answer:
You already know the answer, but anyway it's 10 weeks with y = 0,5x + 0
Step-by-step explanation:
Basically what you have to do to find the equation is to pick 2 random points on the line drawn to get the solution.
I take (0, 0) and (2, 1) because they are the simplest ones.
The equation for finding a line with 2 points (that actually are 4 coordinates x1 = 0, y1 = 0, x2 = 2 and y2 = 0) is:
(x + x1) \ (x2 + x1) = (y + y1) \ (y2 + y1)
that becomes:
(x + 0) \ (2 + 0) = (y + 0) \ (1 + 0)
simplyfing this, it becomes:
x/2 = y ---> y = 1/2x that you can write on the answer page as y = 0,5x + 0
Answer: The equation for this line is y = -1/2 x + 5. If she continues the line, she would see that it would take 10 weeks for her cat to lose 5 pounds.

Liz wanted to buy a new book. When she checked the price last week, it was $19. This week, the same book was listed for $22. Write and solve an equation to show how much the book increased in price.
22 = p + 19; p = $3
22 = p − 19; p = $41
19 + p = 41; p = $22
2p = 22; p = $11

The first person to finish this worksheet will be awarded with 15 points
Thank you!
hey...can we become friends??
Answer:
-16-5-22-45-45-146-19-44Step-by-step explanation:
This is an example for all orders of operations
1. We need to know P.E.M.D.A.S.
(P)lease(E)xcuse (M)y(D)ear (A)unt(S)ally2. PEMDAS is the acronym for the order in which you solve things:
(P)lease = Parentheses Ex: (x+y)(E)xcuse = Exponet Ex: [tex]x^{2}[/tex](M)y = Multiplication Ex: A×B(D)ear = Divide Ex: A÷B(A)unt = Addition Ex: A+B(S)ally = Subtract Ex: A-B3. Now that we know how the order of operations works let to a problem:
Ex: 7×8+(7×2+3)-(5+7)
1. First, we are gonna solve what is inside the parentheses.
2. We will do the first one : (7×2+3)
3. We are gonna use the order of operations to know what we solve first.
It looks like multiplication is firstso we do 7×2 and that =144. So now our parentheses should look like this:
(14+3)5. Now the whole problem should look like this :
7×8+(14+3)-(5+7)6. Now we solve (14+3). That =17. Our whole problem should be like this
7×8+(17)-(5+7)7. Now that we have solved the first parentheses we have to solve the second one: (5+7). that is 12. here is what it looks like in the whole problem:
7×8+(17)-(12)8. Now that we have solved the parentheses we can solve the next one. That is exponents. We don't have any exponents so we can go to the next and that is multiplication.
7×8That is 56the whole problem is now 56+(17)-(12)9. Now we have solved the multiplication we need to do the division. There isn't any so we can go to addition now.
56+17that is 73the whole problem is now 73-1210. Now we do the subtraction
73-12 and that equals 6111. The answer is now solved
NOTE if you have something like this: 3(-3) it means 3×-3
