Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13
Hope this helped, I tried to explain it easily.

Answer:
1=3
Step-by-step explanation:
Subtract the number without the x from the answer then find a multiple of the number with the x for example
5x+2=17
17-2=15
Multiples
X1= 5
X2=10
X3= 15
Answer:
I hope this helps :)
Step-by-step explanation:
- 5x + 2 = 17 -- x = 3
- 3x + 5 = 36 -- x = 10.333
- x/3 - 14 = 9 -- x = 7.667 (Might be wrong)
- 73 = 3x - 20 -- x = 31
- 2x - 14 = 7 -- x = 10.5
- 53 = 9x - 1 -- x = 6
A student usually saves $20 a month. He would like to reach a goal of saving $350 in
12 months. The student writes the equation 12(x + 20) = 350 to represent this situation.
Solve the equation for x.
• Show your work or explain your answer.
• Write your answer as a sentence that describes what the variable x represents
Answer:
Step-by-step explanation:
12x + 240 = 350
12x = 110
x = [tex]\frac{110}{12}[/tex]
x is how much money the student needs to save more amonth. so insead of saving 20 dollars the student would have to save 20+x dollars and x is [tex]9.16666666666.....[/tex]

Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...

Determine the measures of the unknown angles in the figure.
m < APD =
m < CPE =
m < BPD =
Answer:
angle APD=115 degrees
angle CPE=25 degrees
angle BPD=65 degrees
Step-by-step explanation:
APD=180-65=115 because it is supplementary
CPE=90-65=25 because it is complementary
BPD=65 because it is an alternate angle
The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of the asked angles,
m ∠APD, m ∠CPE and m ∠BPD.
So,
∠APD + ∠APC = 180° [linear pair]
∠APD = 180° - 65°
∠APD = 115°
∠CPE + ∠CPA = 90° [complimentary angles]
∠CPE = 90° - ∠CPA
∠CPE = 90° - 65°
∠CPE = 25°
∠BPD = ∠APC [vertical angles]
∠BPD = 65°
Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, find the coordinates of the vertex C
the coordinates of C are...
Answer:
(4, 2)
Step-by-step explanation:
Because ABC is reflected across the y-axis, this means that the y coordinate will remain the same, and the x coordinate is the negative of its original (because it is being flipped)
If the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, then coordinates of the vertex C is (4,2)
What is coordinate system?
a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other.
Given that,
Vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2).
If ABC is reflected across the y-axis to produce the image △ABC.
We need to find the image of △ABC.
We need to find coordinates of vertex C.
As ABC is reflected across the y-axis, this means that the y coordinate will remain the same,
As the triangle is flipped the sign of x coordinate is the negative of its original.
Hence (4,2) is the coordinates of the vertex C.

The calories from the different diets are given below.
1. 2,000 calories diet eat from veggies than from carbs is 200 calories.
2. 1,800 calories diet from fruit is 270 calories.
3. 2500 calorie diet, healthier because they eat more calories is not accurate.
4. 2200 calorie diet eat from protein is 550 calories. Then option B is correct.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
1. The calories should a person on a 2,000 calories diet eat from veggies than from carbs will be
→ 2000 × 0.35 = 700 calories
→ 2000 × 0.25 = 500 calories
→700 – 500 = 200 calories
2. If a person is on a 1,800 calories diet, then the calories will come from fruit will be
→ 1800 × 0.15 = 270 calories
3. A person on a 2500 calorie diet states that they are healthier because they eat more calories from veggies will be
→ 2500 × 0.35 = 875 calories
Because veggies have more calories than others. Thus, inaccurate.
4. The number of calories from protein a person on a 2200 calorie diet should consume will be
