Answer:
-7n - .9
Step-by-step explanation:
By distributing the - to the parentheses, you must add a - sign to each number in the parentheses. This makes the positives turn negative.
make r the subject of the formula t=[tex]\frac{r}{r-3}[/tex]
Answer:
[tex]\displaystyle r=\frac{3t}{t-1}[/tex]
Step-by-step explanation:
We are given the formula:
[tex]\displaystyle t=\frac{r}{r-3}[/tex]
And we are asked to make r the subject of the formula.
We can multiply both sides by r - 3. This reduces the denominator on the right-hand side:
[tex]t(r-3)=r[/tex]
Distribute:
[tex]rt-3t=r[/tex]
Subtracting rt from both sides yields:
[tex]-3t=r-rt[/tex]
Factoring:
[tex]-3t=r(1-t)[/tex]
Divide and simplify:
[tex]\displaystyle \begin{aligned} r & = \frac{-3t}{1-t} \\ \\ & = \frac{3t}{t-1}\end{aligned}[/tex]
In conclusion:
[tex]\displaystyle r=\frac{3t}{t-1}[/tex]

Answer:
Step-by-step explanation:
y = -2x + 4
x y
-1 6
0 4
1 2
2 0
y = -2(-1) + 4 = 2 + 4 = 6
y = -2(0) + 4 = 0 + 4 = 4
y = -2(1) + 4 = -2 + 4 = 2
y = -2(2) + 2 = -4 + 4 = 0

Answer:
In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.
The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon's vertices(singular: vertex) or corners.
So, if a shape has points where two edges meet, it is indeed a polygon. Some examples include: Equilateral Triangles, Squares, Regular Pentagons, Regular Hexagons, Regular Heptagons, and Regular Octagons.

Answer: 740what is b ? -14 - 5b + 2b = -2 - 2(1 - b)
Answer: B = -2
Step-by-step explanation:
-14 - 5b + 2b = -2 - 2(1 - b)
-14 -3b = -2 -2 + 2b
-14 - 3b = -4 + 2b
-10 = 5b
b = -2

When 19346 is divided by a number,the quotient is 841 and the remainder is 3.What is the number?
Answer:
23
Step-by-step explanation:
19346 ÷ 841 = 23.003567.. ( that is 23 with a remainder ), then
23 × 841 = 19343, thus
19346 ÷ 841 = 23 remainder 3
The divisor is 23

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. C. What is the length of bottom side of the scaled copy?
Answer:
The length of bottom side of the scaled copy is 12 u
Step-by-step explanation:
To solve this problem we have to know that to calculate the area of a triangle we use the following formula
a = area
b = base
h = height
a = b * h
In the triangle A the base and the height are equal to 3
b = h
Now that we know that b & h we can calculate the base of the scaled copy
72 u² = b * b
72 u² = (b)²
√(72 u²) = b
12 u = b
The length of bottom side of the scaled copy is 12 u

The proceeds from a car wash are directly proportional to the number of cars washed. The total after 9 cars was $180. How much can be raised if 60 cars
are washed?
60 cars washed?
Answer:
$1200
Step-by-step explanation:
180 divided by 9 is 20, so they earned $20 per car washed. They want to wash 60 cars, and if they wash 60 cars they would earn $1200. (60 x 20)
Answer:
$1200
Step-by-step explanation:
Our revenue is directly proportional to the number of cars. That means our revenue is increasing at a constant rate, and thus, we are getting the same amount of money per car. That means we can find out how much we get from washing 1 car.
[tex]\frac{180}{9} = 20[/tex]
$20 per car.
If we washed 60 cars, we'd earn 60 * $20:
[tex]60*20 = 1200[/tex]
Answer: $1200
