Answer: 1.25
Step-by-step explanation:
To solve this, we.will use the formula,
y = kx
where,
y = water depth
k = constant of proportionality
x = time
Using y = kx
2.5 = 2k
k = 2.5/2
k = 1.25
Also,
y = kx
3.75 = 3k
k = 3.75/3
k = 1.25

Answer:
x= 0
y= -3
Step-by-step explanation:
6x-5y=15
substitution...
6(y+3)-5y=15
6y+18-5y=15
y+18=15
-18 -18
y= -3
substitution again...
6x-5(-3)=15
6x+15=15
-15 -15
6x=0

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
6x - 5y = 15
x = y + 3
Step 2: Solve for y
Substitution
Substitute in x: 6(y + 3) - 5y = 15Distribute 6: 6y + 18 - 5y = 15Combine like terms: y + 18 = 15Isolate y: y = -3Step 3: Solve for x
Define original equation: x = y + 3Substitute in y: x = -3 + 3Add: x = 0how many solutions?
Answer:A) no solutions
Step-by-step explanation:
1) set both problems equal to each other
2) subtract four from each side
3) subtract 2x from each side
4) 10 does not equal 0
Answer:
No solution
Step-by-step explanation:
As soon as you minus the equations from each other, the y's and x's cancel out therefore there is no solution

Answer:
The answers are
x=-2
m=23
a=-24
x=6
Answer:
Step-by-step explanation:
1. x+5=3
x= 3-5=-2
2. m-4=19
m= 19+4=23
3. a÷6=-4
Multiply by 6 on both sides we get
a = -4×6=-24
4. -6x =-36
Divide by -6 on both sides
x =6

m deep and of diameter 2.8 m?
Answer:
43.103m³
Step-by-step explanation:
This is just finding the volume of a cylinder problem.
Area of a circle = πr²
Area of circle * length of cylinder = volume
3.14*(1.4)² = 6.158m²
6.158*7 = 43.103m³

7(6-y)=-3(y-2)
Answer:
y=9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont contain the variables
move variable to left side and change its sign
42-7y+3y=6 collect like terms
-7y +3y=6-42
-4y=6-42
-4y=-36 divide both sides of the equation by -4

There are 18 people on a basketball team, and the coach needs to choose 5 to put into
a game. How many different possible ways can the coach choose a team of 5 if each
person has an equal chance of being selected?
Answer:
He can choose by each players skill and depending on how long the game is he can sub them out throughout the game
Step-by-step explanation:
The total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is, 8568 or C(18, 5)
What are permutation and combination?A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.
We have 18 people on a basketball team.
The coach needs to choose 5 to put into a game.
So the total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is:
[tex]= \rm _{18}^{}\textrm{C}_5[/tex]
[tex]= \dfrac{18!}{5!\times 13!}[/tex]
= 8568
Thus, the total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is, 8568 or C(18, 5)

Is an equation that has 0 for a solution the same as an equation with no solution? Explain.
Answer:
No.
Step-by-step explanation:
The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation.
2х + Зу = 9
3х + 5y = 16
Elimination
x=-3, y=5
2х + Зу = 9
3х + 5y = 16
6x + 9y = 27
6x + 10y = 32
-y = -5
y = 5
2x + 3(5) = 9
2x = 9-15

Can someone please help me with solving this maths question?
Answer:
CD = 7
Step-by-step explanation:
Given that the triangles are congruent, then corresponding sides are congruent, that is
CD = AB , substitute values
3y + 1 = 15 - 4y ( add 4y to both sides )
7y + 1 = 15 ( subtract 1 from both sides )
7y = 14 ( divide both sides by 7 )
y = 2
Thus
CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7
