Answers
Answer:
Step-by-step explanation:
The required solutions of the given system of equations is x = -7 and y = -5.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Given system of equation
y=x+2 - - - - -(1)
y=4x+23 - - - - (2)
From above equations,
x + 2 = 4x + 23
x = -7
Now,
y = -7 + 2
y = -5
Thus, the required solutions of the given system of equations is x = -7 and y = -5.

Step-by-step explanation:
Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.
A. c(p) = p + 0.59
B. c(p) = 59p
C. c(p) = p/0.59
D. c(p) = 0.59p
Answers
Answer:
D. c(p) = 0.59p
Step-by-step explanation:
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,
c(p) = ($0.59)p
We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost
c(p) = .59*p

MODELING REAL LIFE A green roof is like a traditional roof but covered with plants. Plants used for a green roof cost $0.75 per square foot. The roof shown is 40 feet long. How much does it cost to cover both sides of the roof?
Answers
Answer:
$1200
Step-by-step explanation:
Let the roof be square shaped
Area of the roof = L²
L is the side length of the roof
Given
L = 40ft
Area of the roof = 40²
Area of the roof = 1600ft²
If plants used for a green roof cost $0.75 per square foot, this means
1 ft² = $0.75
Let the cost needed to cover both sides of the roof be y, hence;
1600ft² = y
Divide both expressions
1/1600 = 0.75/y
y × 1 = 0.75×1600.
y = 0.75×1600
y = 1200
Hence it will cost $1200 to cover both sides of the roof

Find m∠STU and m∠TUA
Answers
Answers:
angle STU = 65 degreesangle TUA = 123 degrees=========================================================
Explanation:
Let's find the expression for angle TUS in terms of x
Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees
(angle TUS) + (angle TUA) = 180
angle TUS = 180 - (angle TUA)
angle TUS = 180 - (11x + 2)
angle TUS = 180 - 11x - 2
angle TUS = -11x + 178
Now focus on the interior angles of triangle TUS. We have these three angles
T = 5x+10U = -11x+178S = 58For any triangle, the interior angles always add to 180, so,
T+U+S = 180
(5x+10) + (-11x+178) + (58) = 180
(5x-11x) + (10+178+58) = 180
-6x + 246 = 180
-6x = 180-246
-6x = -66
x = -66/(-6)
x = 11
Use this x value to find the angle measures we're after:
angle STU = 5x+10 = 5*11+10 = 55+10 = 65 degreesangle TUA = 11x+2 = 11*11+2 = 121+2 = 123 degrees--------------------------
As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.
In this case, we would say
(angle STU) + (angle TSU) = angle TUA
that leads to the equation
(5x+10) + (58) = 11x+2
Solving this should lead to x = 11 to generate the angles mentioned earlier.

Somone please help I am completely lost...
Answers
The first one says x+2x+4y.
So the first thing you would do is combine like terms.
x and 2x are like terms.
Since x has no number you would have to put a 1 in place for it.
So you would have 1x+2x which would be 3x.
You would then put that together and have 3x+4y.

Brain has two rectangular sheets of paper.
-The length of the larger sheet is 1 1/2 times the length of the smaller sheet.
-The width of the larger sheet is 1 3/5 times the width of the smaller sheet.
By what factor is the area of the larger sheet greater than the area of the smaller sheet?
Answers
Answer:
2.4
Step-by-step explanation:
Smaller sheet length = 10u
Smaller sheet width = 10u
Smaller sheet area = 10u * 10u = 100u^2
Larger sheet length = 1.5 * 10u = 15u
Larger sheet width = 1.6 * 10u = 16u
Larger sheet area = 16u * 15u = 240u^2
240u^2 / 100u^2 = 2.4
The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.
Calculation of the factor:Since
Smaller sheet length = 10u
Smaller sheet width = 10u
Now
Smaller sheet area = 10u (10u) = [tex]100u^2[/tex]
And,
Larger sheet length = 1.5 ( 10u) = 15u
And,
Larger sheet width = 1.6 (10u) = 16u
So,
Larger sheet area = 16u (15u) = [tex]240u^2[/tex]
Now
[tex]= 240u^2 \div 100u^2[/tex]
= 2.4
hence, The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.
