Question:
Simplify -2¹/9 – -4⅓
Answer:
-2¹/9 – -4⅓ when simplified is 20/9
Step-by-step explanation:
Given
Simplify -2¹/9 – -4⅓
First, we need to convert both fractions from mixed fraction to improper fraction
-2¹/9 = -(18+1)/9
-2¹/9 = -19/9
-4⅓ = -(12+1)/3
-4⅓ = --13/3
So, -2¹/9 – -4⅓ becomes
-19/9 - - 13/3
-19/9 + 13/3
Find LCM of both fractions (9)
(-19 + 39)/9
20/9
Hence, -2¹/9 – -4⅓ when simplified is 20/9

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the measure of angle B?
Enter your answer as the correct value, like this: 42
Answer:
168
Step-by-step explanation:
b + c = 180
b = 14c
14c + c = 180
15c = 180
c = 12
b + c =180
b + 12 = 180
b = 168

A. Sarah's bill at the restaurant was $12.81. She left a tip of 20%. What was the tip amount? Round your answer to the nearest hundredth.
B. What was the total bill? Round your answer to the nearest hundredth.
Answer:
A. $2.56
B. $15.37
Step-by-step explanation:
A. When you’re asking what is a certain percent of a specific number, you turn the percent into a decimal and multiply it by the specific number. In this case, 0.20 * 12.81 = 2.562
Since we are to round to the nearest hundred, that leaves us with $2.56.
B. To get the total bill, add 12.81 and 2.56 to get a total of $15.37.

Find what the x is.
45= 5/7x
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
[tex]45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}[/tex] [tex]63 = x[/tex]Step 2: Check if solution is correct.
[tex]45 = \frac{5}{7}(63)[/tex] [tex]45 = 5 * 9[/tex] [tex]45 = 45[/tex]Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler
Answer:
Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

Someone help me please and thank you.
Also please show work.
Answer:
1 13/24
Step-by-step explanation:
First we need to find the LCD (lowest common Denominator) which will be 24. When we multiply 8 x 3 = 24 we will also multiply 5 by 3 which equals 15. So 5/8 = 15/24. Then we multiply 12 x 2 = 24, and again we also multiply the numerator by the same number which is 11 x 2 = 22. So 11/12 = 22/24.
Now that we have the LCD then we can add up the two. So 15/24 + 22/24 = 37/24. Now we need to simplify that to 1 13/24. Thank you.

in kick boxing, it is found that the force needed to break a board varies inversely with the length of the board. If it takes 5 lbs. of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8 feet long
Answer:
20
Step-by-step explanation:
Since we know that it takes 5lbs. to break a 2-foot longboard, we first want to figure out how many pounds it takes to break a 1foot board.
5/2=2.5
It takes 2.5 lbs to break a 1-foot board.
2.5x8=20
It would take 20lbs to break an 8-foot longboard.
Hope this helps :)

Keith will run at most 26 miles this week. So far, he has run 14 miles. What are the possible numbers of additional miles he will run? Use t for the number of additional miles he will run. Write your answer as an inequality solved for t.
Answer:
[tex]t \leqslant 12[/tex]
Step-by-step explanation:
We know that Keith has ran 14 miles already, and he's aiming to reach no more than 26 miles, this week.
So we can put:
[tex]14 + t \leqslant 26[/tex]
Since, 14 is the number we know, t represents the number we have yet to find, and 26 is the product of this inequality. (We use the less-than-or-equal-to sign, because Keith is only aiming for 26 or less miles.)
Now we solve:
Subtract 14 on both sides to get
[tex]t \leqslant 12[/tex]
So t is less-than-or-equal-to 12, meaning Keith has 12 or less miles to run in order to reach 26 miles.
Hope this helps :)

The length and width of a square is 9.5 inches (for both) what is the area and perimeter?
Answer:
90.25, 38
Step-by-step explanation:
The area is the two sides multiplied against each other, so 9.5*9.5
Since it's a square all of the sides are 9.5 inches, so just multiply 9.5 times 4 for the perimeter

(2x+1)(x+5)
6x-4xy
16x^2-25
Step-by-step explanation:
i believe what you need help on is simplifying the equations. so let's start with the first one.
====================================================================
(2x+1)(x+5) original problem
(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.
2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.
2x2+11x+5 this is the most simplified equation.
====================================================================
6x−4xy original problem.
unlike the last problem, we can easily just... 6x + (−4xy).
−4xy+6x this is the most simplified equation.
====================================================================
ok, the last one. phew!
unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.
if we factored, we would get...
(4x+5)(4x−5)
===================================================================
