Answer:
z = -3
Step-by-step explanation:
Simplifying
3z + -3 = 2z + -6
Reorder the terms:
-3 + 3z = 2z + -6
Reorder the terms:
-3 + 3z = -6 + 2z
Solving
-3 + 3z = -6 + 2z
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-2z' to each side of the equation.
-3 + 3z + -2z = -6 + 2z + -2z
Combine like terms: 3z + -2z = 1z
-3 + 1z = -6 + 2z + -2z
Combine like terms: 2z + -2z = 0
-3 + 1z = -6 + 0
-3 + 1z = -6
Add '3' to each side of the equation.
-3 + 3 + 1z = -6 + 3
Combine like terms: -3 + 3 = 0
0 + 1z = -6 + 3
1z = -6 + 3
Combine like terms: -6 + 3 = -3
1z = -3
Divide each side by '1'.
z = -3
Simplifying
z = -3
Answer:
=3z+3=2z+6
=3z-2z=6-3
=z=3

Sue wants to put a rectangular garden on her property using 88 meters of fencing. There is a river that runs through her property so she decides to increase the size of the garden by using the river as one side of the rectangle. (Fencing is then needed only on the other three sides.) Let x represent the length of the side of the rectangle along the river. Express the garden's area as a function of x. what is the largest area that can be enclosed?
Answer:
Area = 44x - x²/2
Step-by-step explanation:
Given that:
Meter of fencing = 88m
Length of side of rectangle along the river = x
Only one more length is needed since river as been used as one side length of the fence.
Length = x
Width of rectangle = y = 2y (for both sides)
Hence ;
x + 2y = 88 meters
Expressing in terms of y
2y = 88 - x
y = (88 - x) / 2
y = 44 - x/2
Area of rectangle = Length * width
Area = x * y
Area = x * (44 - x/2)
Area = 44x - x²/2
Maximum. Area :
Perimeter = 4s
88 = 4s
s = 88/4 = 22
x = 2(22) = 44 = Length ; y = 22 = width
Maximum area = (22 * 44) = 968m²

Answer:
∠ S = 55°
Step-by-step explanation:
∠ R and ∠ S are vertical angles and congruent, thus
∠ S = ∠ R = 55°
Can anybody please help me out with this question please I would really appreciate it so much. please and thank you .
Answer:
∠ BAF = 140°
Step-by-step explanation:
Since BD is a tangent to the circle at point B , then
∠ ABD = 90°
The exterior angle of a circle is equal to the sum of the 2 opposite interior angles.
∠ BAF is an exterior angle, thus
∠ BAF = ∠ ABD + ∠ BDA = 90° + 50° = 140°

4. A person is earning P600 per day to do a certain job. Express the total salary
S as a function of the number n of days that the person works.
Answer: S = P600 × n
Step-by-step explanation:
Amount earned per day = P600
Number of days used = n
The total salary s, will be the value of p600 multiplied by n. This will be:
= P600 × n
Therefore, the function regarding the total salary, s will be: P600 × n

Connor bought a baseball card eight years ago that has depreciated (goes down in value) by $120 since he purchased it. Find the average yearly change in the value of the card.
and show me how did you do it
Answer:
-$15
Step-by-step explanation:
To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.
-120/8
= -15
So, the average yearly change in the value of the card is -$15
Answer:
$120/8= $15 in a year.
15 times 8 is 120.

12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)
Step-by-step explanation:
Length = x
Width = (x-5)
Perimeter = 2 lengths + 2 widths
50 ft = x + x + (x-5) + (x-5)
50 ft = 4x - 10
60 ft = 4x
15 ft = x
length = x = 15 ft
width = (x-5) = (15 -5) = 10 ft
dimensions = length × width
= 15 ft × 10 ft
if you wanna check,
50 ft = x + x + (x-5) + (x-5)
50 ft = 15 + 15 + (15-5) + (15-5)
50 ft = 30 +(10+10)
50 ft = 30 + 20
50 ft = 50

Is ∆GAS ≅ △_____
By rule____
Answer:
ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Step-by-step explanation:
The given information are;
Statement [tex]{}[/tex] Reason
Segment [tex]\overline {SA}[/tex] is congruent to [tex]\overline {OL}[/tex] [tex]{}[/tex]As shown in the diagram provided
∠SAG is congruent to ∠LOI [tex]{}[/tex] As shown in the diagram provided
∠SGA is congruent to ∠LIO [tex]{}[/tex] As shown in the diagram provided
Therefore, ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Given that the the number of interior angles of triangle = 3 and the sum of the interior angles of a triangle = 180°, the third angle can be defined by specifying the measure of two of the angles
Therefore, the Angle-Angle (AA) rule of similarity can be used to prove the congruency of two triangles when they have one side of each triangle which are congruent.
Answer:
∆GAS ≅ △IOL By rule ASA, AAS
Step-by-step explanation:
By looking at the triangle, you can see two little quarter-circle things inside the triangle (I don't know what they are called). That means it has 2 angles. We already know that it can't be SSS or SAS because we have 2 angles, as I said.
If you look at the triangle's sides, you can see that there is a side with a dash on it. That means that it is a side in ASA, AAS, etc. So there we go. We've figured it out. There is one side and two angles. Therefore, our answer is ASA or AAS
On Monday, Jayla raised $30 and Carlos raised $50.
After that, Jayla raised $12 per day and Carlos
raised $7 per day. After how many days will they
have raised the same amount?
They will raise the same amount after days.
Answer:
84 days
Step-by-step explanation:
You would use the LCM to solve this.
12 and 7 don't share any common factors other than 1,
so you would multiply 12 x 7, which gets you 84.
After 84 days they would have raised the same amount.
