Pls give me the hole equation
Answers
Answer:
x = 2
y = -3
Step-by-step explanation:
2x + 2y = -2, then 2y = -2 - 2x
3x - 2y = 12, then 2y = 3x - 12
so:
-2 - 2x = 3x - 12
add 2x and 12 to each side of the equation:
5x = 10
divide both sides by 5:
x = 2
2y = 3(2) - 12
2y = -6
divide both sides by 2:
y = -3

3(3u-2)=2(3u+3)
What is the steps
Answers
Answer: u = 4
1. Expand.
9u - 6 = 6u + 6
2. Add 6 to both sides.
9u = 6u + 6 + 6
3. Simplify 6u + 6 + 6 to 6u + 12.
9u = 6u + 12
4. Subtract 6u from both sides.
9u - 6u = 12
5. Simplify 9u - 6u to 3u.
3u = 12
6. Divide both sides by 3.
u = 12/3
7. Simplify 12/3 to 4.
u = 4

What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
Total number of hits = 18
Doubles + triples = 18
Let x be the number of triples. Then
Number of doubles = 18-x
Number of bases for doubles = 2 bases
Number of bases for triples = 3
The equation for the above situation is
⇒ [tex]2(18-x)+3x=42\\[/tex]
⇒ [tex]36-2x+3x=42[/tex]
⇒ [tex]x=42-36[/tex]
⇒ [tex]x=6[/tex]
Hence we can conclude that the number of triples is 6.

Answers
Question: Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 4 cm 15 cm a. 15.5 cm
b. 30 cm
c. 60 cm
d. 34.5 cm
Answer:
d. 34.5 cm
Step-by-step explanation:
Applying
Perimeter of the right triangle (P) = a+b+c
P = a+b+c.................... Equation 1
But we can find the hyotenuse (a) using pythagoras theorem
a² = b²+c²
a = √(b²+c²)............... Equation 2
Substituting equation 2 into equation 1
P = √(b²+c²)+b+c................... Equation 3
From the diagram,
Given: b = 4 cm, c = 15 cm
Substitute these values into equation 2
P = √(4²+15²)+4+15
P = √(241)+4+15
P = 15.5+4+15
P = 34.5 cm
Hence the right answer is d. 34.5 cm
