Answer:
-5
Step-by-step explanation:
Because this equation is in standard form you can do -A/B which is the first two numbers of the equation, and since -A=5 and B=y(1) then i just did -5/1 and i got -5
A rectangle’s perimeter and its area have the same numerical value. The length of the rectangle is 6. What is the width of the rectangle in units?.
Answer:
Step-by-step explanation:
Formula
P = 2*w + 2*L
Area = L*w
Givens
Area = P
L = 6
Create equation and Solve
LW = 2w + 2L
6w = 2w + 2*6
6w = 2w + 12 Subtract 2w from both sides
6w - 2w = 12 Combine
4w = 12 Divide by 4
4w/4 = 12/4
w = 3
Check
Area = 6*3 = 18
Perimeter = 2*3 + 2*6
Perimeter = 6 + 12 Combine
Perimeter = 18
It does check.
The perimeter of a room is 14th. Find the total cost of painting the four walls at the rate of rs 60 per m square .If the height of the room is 4m
Answer:
Rs 6720.
Step-by-step explanation:
Given,
Perimeter of room ( P ) = 14m
Height of room ( H ) = 4m
Area of 4 wall = 2 × 14 ×4
= 112m sq.
Now,
Cost = 112 × 60
= Rs 6720.
the math club is having a bike sale to raise money for the regional math tournament.the make a $5 for each cake sold. the booster club gave a $100 donation
Answer:
20 cakes were sold

set up equation
$5 per cake equals $100
5x = 100
divide both sides by 5
5x ÷ 5 = 100 ÷ 5

A company manufactures two types of electric hedge trimmers, one of which is cordless. The cord-type trimmer requires 2 hours to make, and the cordless model requires 6 hours. The company has only 600 work hours to use in manufacturing each day, and the packaging department can package only 200 trimmers per day. If the company profits for the cord-type model for $36.50 and the cordless model for $109.50, how many of each type should it produce per day to maximize profits?
Answer:
P=$14600The company should produce 100cordless and 100 cord-typeStep-by-step explanation:
This is a linear programming question
let the cordless trimmer be X
and the cord type be Y
the objective function is
maximize
36.50x+109.50y=P
constraints
2X+6Y<=600-----1
X+Y=200-----------2
solve 1 and 2 simultanouesly
mutiply eqn 2 by 2 we have
2x+6y=600-------1
2x+2y=200--------3
subtract the eqns 3 from 1
4y=400
y=100
put y=100 in eqn 2 we have
x+100=200
x=200-100
x=100
36.50x+109.50y=P
36.50(100)+109.50(100)=P
3650+10950=P
P=$14600

Olivia and Jessica have in total half as many sweets as Fran and Gary have in total.
14
Fran and Gary share their sweets in the ratio 2:3
Olivia and Jessica share their sweets in the ratio 9: 1
Fran got w sweets.
Gary got x sweets.
Olivia got y sweets.
Jessica got z sweets.
Find, in its simplest form, w:x:y:z
The simplest form of w : x : y : z will be;
⇒ w : x : y : z = 20 : 30 : 9 : 1
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
Olivia and Jessica have in total half as many sweets as Fran and Gary have in total.
Now,
Let Fran got w sweets.
Gary got x sweets.
Olivia got y sweets.
Jessica got z sweets.
So, We get;
⇒ (y + z) = 1/2 (x + w) ..(i)
Here, w = 2a and x = 3a
And, y = 9b and z = b
Substitute in equation (i), we get;
⇒ (y + z) = 1/2 (x + w)
⇒ (9b + b) = 1/2 (2a + 3a)
⇒ 10b = 1/2 (5a)
⇒ 20b = 5a
⇒ 10b = a
So, w = 20b and x = 30b
Or, w : x = 20b : 30b
So, w : x: y: z = 20b : 30b : 9b : b
= 20 : 30 : 9 : 1
Thus, The simplest form of w : x : y : z will be;
⇒ w : x : y : z = 20 : 30 : 9 : 1

find the area of the given figure?
Answer:
19
Step-by-step explanation:
The first thing is recognize that it is a rectangle and two triangles with given bases and heights.
So the first step is finding the area of both triangles, which you can do with the formula for the area of a triangle:
A = (BH)/2
Because the height is two, the area is going to be equal to the base.
The sum of the two triangles is 7.66.
Next you want to find the area of the rectangle, you can do so using the formula:
A = BH
A = 6(2)
The area of the rectangle is 13.
Find the sum of the areas of the three shapes.
3.30 + 4.36 + 12 = 19.66

A local amusement park sells large drinks for $5.75. the park offers a large commemorative drink container for $22.99. attendees who purchase the commemorative container get refills up to 12 times for $2.09 each during the day of purchase. Let x represent the number of large drinks consumed, f(x) represent the amount spent
SOMEONE PLS HELP THIS IS DUE IN AN HOUR
Answer:
5.75x = f(x)
22.99 + 2.09x = g(x)
Step-by-step explanation:
Divide them into two parts:
Normal drinks and commemorative drinks
- With normal, only $5.75 is related (Only one drink at a time so 5.75x)
- With commemorative, $22.99 and $2.09 are related (A one time fee of $22.99, then a refill of $2.09; so 22.99 + 2.09x)

passes through the points (3, -1) and (1, 1).
Plug it in.
y = -1, y1 = 1
x = 3, x1 = 1
-1 - 1 = m( 3 - 1)
-2 = 2m
m = -1
The slope is -1
y = -x +b

iii. identify the type and number of atoms in each molecule of the reactants and products.
iv. explain what happens during the chemical reaction.
v. explain how mass is conserved during the chemical reaction
Assignment: Type one to two paragraphs that describe your models and relate them to the law of conservation of mass. Your document should:
Identify the names of the reactants and products in the reaction.
Identify the number of molecules that make up the reactants and products.
Identify the type and number of atoms in each molecule of the reactants and products.
Explain what happens during the chemical reaction.
Explain how mass is conserved during the chemical reaction
The name of the reactant in this reaction is called Calcium Carbonate (CaCO3) and the products in this reaction are Calcium Oxide (CaO) and Carbon Dioxide (CO2). There are 5 atoms total in calcium carbonate: one calcium atom, one carbon atom, and 3 oxygen atoms. In calcium oxide there are 2 atoms total: one calcium atom and one oxygen atom. In carbon dioxide there are 3 atoms total: one carbon and two oxygen atoms. So in the reaction the mass of the products stayed the same because according to the law of conservation, “in a closed or isolated system, matter cannot be created or destroyed. It can change forms but is conserved.” This can be seen in the reaction because no matter was made or destroyed, it was all just rearranged. To further explain, the law of mass conservation in chemistry states that, “in a chemical reaction, the mass of the products equals the mass of the reactants,” which further proves that no matter was created or destroyed, just rearranged. In conclusion, in the reaction the products had the same number of atoms as the reactant because no matter was destroyed or created, simply rearranged to create new products!

Answer:
Many solutions
