Answer:
-34
Step-by-step explanation:
you would first solve it like a normal equation and ignore the negative;
0.5 * 4 is 2
8 * 4 is 32
32 + 2 = 34
and then you would add the negative sign- because there is only one side with a negative sign, it is negative
if the equation had both sides had a negative, it would be positive

What kind of angles are 4 and 5
what is the value of x?
Answer:
x=18
Step-by-step explanation:
the sum of all the angles in a triangle is 180 degrees.
we can use this to get an equation:
5x-6 + 3x+13 + 2x-7 = 180
combine the x's to get:
10x-6-7+13=180
combine the numbers to get:
10x=180
divide both sides by 10 to get your answer:
x=18

Answer:
Tina ate 1/4 cornbread of the whole pan.
Step-by-step explanation:
If she has 1/2 of a pan, and ate 1/2 of that, it's 1/2*1/2, which equals 1/4! Try to imagine a pan of cornbread in your head ahaha
The equation should be: 1/2*1/2=1/4
Hopes this helps!
Can someone help me do this
Find the slope of the line that passes through (6, 10) and (4, 3).
Answer:
7/2
Step-by-step explanation:
1. To find the slope given two points, you can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] (by plugging in corresponding values and simplifying) and then find it!
2. (Solving)
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] [tex]\frac{(3)-(10)}{(4)-(6)}[/tex] [tex]\frac{-7}{-2}[/tex] [tex]\frac{7}{2}[/tex]Therefore, the slope of the line is 7/2.

A cloud drifted above an airplane that was flying at 5,300 meters per minute. In 22.5minutes, the cloud moved 7,920meters to the east at a constant velocity. What was the cloud's velocity?
Answer is 352 metres
Step-by-step explanation:-The cloud is moving at a constant velocity. This means that we can find the velocity of the cloud by dividing the distance it moved by time:-
[tex]v = \frac{d}{t} [/tex]
Where "v" is velocity, "d" is distance and "t" is time.
The cloud moved 7920 metres in 22.5 minutes, so :-
[tex]v = \frac{7920 \: m}{22.5 \: min} [/tex]
[tex]v = 352 \: m/min[/tex]
Therefore, the cloud's velocity was 352 m/min.

Answer:
Step-by-step explanation:
Linda is twice as old as Vera. Tanya is four less than four times the age of Linda. Their total age is two more than nine times the age of Vera. How old is Tanya, in years?
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
Let the age of Vera be x,
Linda's age = 2x
Tanya's age = (4 × 2x) - 4 = 8x - 4
Total Age = 9x + 2
so, let's Solve for x :
[tex]x + 2x + 8x - 4 = 9x + 2[/tex][tex]11x - 4 = 9x + 2[/tex][tex]11x - 9x = 2 + 4[/tex][tex]2x = 6[/tex][tex]x = 3[/tex]Age of Tanya :

A store sells 5-pound bags of potatoes for $2.35 or 8-pound bags of potatoes for $3.52. Based on this information, which statement is true?
I don't know what the answer choices are
5 pound = $2.35
8 pound = $3.52
2.35/5 = 0.47
3.52/8 = 0.44
The 8 pound bag costs less dollars per pound than the 5 pound bag

Equation of the line:-
[tex]\\ \sf\longmapsto y=2x-5[/tex]
Answer:
y = 2x - 5
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of line

Hamish buvs a new car for $20000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $
Answer:
The correct answer is $10,629
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 20,000 from the word problem.
Next, multiply 20,000 with 0.81 with the power of 3
[tex]20,000*0.81^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.81^3[/tex]
[tex]0.81*0.81*0.81=0.531441[/tex]
(Wow, that's a crazy number!)
--
With 0.531441, multiply it with 20,000
[tex]20,000*0.531441=10628.82[/tex]
10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).
--
Finally, it states to answer to the nearest $.
Just round up the .82 to 1 dollar which will just add one more dollar to 10,628
[tex]10,628[/tex] ⇒ [tex]10,629[/tex]
Add you $ symbol
With the result being: $10,629
Answer:
$10629
Step-by-step explanation:
First you have to work otu the percentage decrease:
100 - 19 = 81
81/100 = 0.81 (/ means divide)
Then you have to work the amount after 3 years:
Long Method
20000 x 0.81 = 16200
16200 x 0.81 = 13122
13122 x 0.81 = 10628.82
or Short Method
20000 x 0.81³ = 10628.82
Finally you round it to the nearest $:
10628.82 ⇒ 10629

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.
Work out Pip's share.
==========================================================
Work Shown:
x = Ali's share
4x = Pip's share, because it is four times bigger due to the ratio 4:1
x+4x = 5x = total amount of money = 785
5x = 785
x = 785/5
x = 157 dollars is Ali's share
4x = 4*157 = 628 dollars is Pip's share
Note that 157+628 = 785 to help confirm the answer.
A soccer team is having a car wash. The team spent $50 on supplies. They earned $300, including tips. The team's profit is the amount the team made after paying for supplies. Use a sum of integers to find the team's profit. The team's profit was $
Answer:the answer is $ f(x) = 3x + 50
f(22) = 3(22) + 50
f(22) = 66 + 50
f(22) = 116
So, he will make $116.

Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
[tex]\frac{3}{5} +\frac{1}{6} =\frac{3*6}{5*6} +\frac{1*5}{6*5} =\frac{18}{30} +\frac{5}{30} =\frac{18+5}{30} =\frac{23}{30}[/tex]
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 6) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - three fifths plus one sixth = twenty-three thirtieths.
Subtract: [tex]\frac{2}{3} =\frac{23}{30} -\frac{2}{3} =\frac{23}{30}-\frac{2*10}{3*10} =\frac{23}{30}-\frac{20}{30}=\frac{23-20}{30} =\frac{3}{30} =\frac{3*1}{3*10} =\frac{1}{10}[/tex]
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(30, 3) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 30 × 3 = 90. In the next intermediate step, , cancel by a common factor of 3 gives [tex]\frac{1}{10}[/tex]
In words - twenty-three thirtieths minus two thirds = one tenth.
