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

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
NEED HELP!!!
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.

Answer:
D (-3, 1)
Step-by-step explanation:
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
2x = -6
x=-3

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)
