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

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)

a) ( 2 + 2 + 2) a) 9a(x – 3b ) - 4 (x – 3b)
b) 5a(2b – 3 ) - 4 (2b – 3)
c) x( 2h-k )+ 3y ( k – 2h )
Answer:
a) 9a(x - 3b) - 4(x - 3b) = (9a - 4)(x - 3b)
b) 5a(2b - 3) - 4(2b - 3) = (5a - 4)(2b - 3)
c) x(2h - k) + 3y(k - 2h)
= x(2h - k) - 3y(2h - k)
= (x - 3y)(2h - k)
Step-by-step explanation:
Answer:
a) (9a-4)(x-3b)
b) (5a-4)(2b-3)
c) (x-3y)(2h-k)
Step-by-step explanation:
9a(x – 3b ) - 4 (x – 3b) = (9a-4)(x-3b)
Since both 9a and -4 are multiplied by (x-3b), they can be put in a bracket too.
5a(2b – 3 ) - 4 (2b – 3) = (5a-4)(2b-3)
Since both 5a and -4 are multiplied by (2b-3), they can be put in a bracket too.
x( 2h-k )+ 3y ( k – 2h ) = x(2h-k) - 3y (-k + 2h)
We can multiply + 3y ( k – 2h ) by (-1) to switch up the arithmetic operations.
x(2h-k) - 3y (-k + 2h) = x(2h-k) -3y(2h-k)
Since both x and -3y are multiplied by (2h-k), they can be put in a bracket too.
x(2h-k) -3y(2h-k) = (x-3y)(2h-k)

Gary has 23 quarters in his bank he saves 4 more quarters each week what will the total value of Gary’s bank be in four weeks??
Answer:
39 quarters, or 9.75 dollars.
Step-by-step explanation:
We can turn this into an algebra equation.
23 + 4x If x = 4
x stands for the number of weeks.
After solving that, we get 39 quarters.
To turn it into dollars, we divide it by 4 (because 4 quarters is equal to one dollar) and then we get 9 3/4. 3/4 dollars is just .75 cents, so the answer is 9.75 dollars.
Garry will have 39 quarters or $9.75 in his bank as per linear equation in 4 weeks.
What is a linear equation?A linear equation is an equation where the variable has the highest power of one.
Give, Garry has 23 quarters.
He saves 4 quarters each week for the next weeks.
Therefore, after 4 weeks Garry will save a total of (4 × 4) quarters = 16 quarters.
Hence, after 4 weeks Garry will have in his bank account is (23 + 16) quarters = 39 quarters = $9.75.

Answer:
125%
Step-by-step explanation:
(9/4)X = (1 +5/4)X = (1 +1.25)X = X + 125%·X
Jack needs to increase X by 125% to get 9/4X.
_____
Example:
X = 100, 9/4X = 225
125%X = 125, so X + 125%X = 100 +125 = 225 . . . as required.

Anna has more money than Betty. If Anna gave Betty $200, then they would have the same amount of money. While if Betty gave Anna $220, Anna would then have twice as much as Betty. Calculate the amount of money each girl has using the substitution method
Answer:
Anna has $1460
Betty has $1060
Step-by-step explanation:
let Anna's money be x
and Betty's money be y
If Anna gave Betty $200, then they would have the same amount of money
Anna's money will reduce by 200
x=x-200
Betty's money will increase by 200
y= y+200
if they have the same amount of money, the difference will be zero
x-200=y+200
x-200-y-200=0
x-y-400=0
x-y=400--------------1
this means that Anna has $400 more than Betty
if Betty gave Anna $220, Anna would then have twice as much as Betty.
Betty's money will reduce by 220
y=y-220
Anna's money will increase by 220
x=x+220
Anna's money will double that of Betty's
x+220=2(y-220)
x+220= 2y-440
x=2y-440-220
x=2y-660--------------------2
put x= 2y-660 in eqn 1
(2y-660)-y=400-------------------------1
2y-y=400+660
y= 1060
so Betty has $1060
put y= 1060 in eqn 1
x-y=400
x-1060=400
x=400+1060
x=1460
so Anna has $1460
