Answer:
A. x + y = 4000
5x + 3y = 15000
Step-by-step explanation:
Total amount raised = $15000
cost of adult tickets = $5
cost of student tickets = $3
Total number of tickets sold = 4000
number of adult tickets sold = x
number of student tickets sold = y
Then we can say,
total number of ticket sold = number of adult tickets + number of student tickets
4000 = x + y
⇒ x + y = 4000 ............. 1
Also,
5x + 3y - 15000 ............. 2
the equations required are:
x + y = 4000
5x + 3y - 15000
Jayce bought 5 bath towels and returned 2 hand towels. His sister Jayna bought 3 bath
towels and returned 4 hand towels. Jayce paid a total of $124 and Jayna paid a total of
5b - 2h = 124
$24. The system of equations
models this situation, where b is the
3b - 4h = 24
price of a bath towel and h is the price of a hand towel. How much does each kind of
towel cost?
Answer:
Bath towels = $32
Hand towels = $18
Step-by-step explanation:
Given:
5b - 2h = 124 (1)
3b - 4h = 24 (2)
Multiply (1) by 2 to eliminate h
10b - 4h = 228 (3)
3b - 4h = 24 (2)
Subtract (2) from (3)
10b - 3b = 248 - 24
7b = 224
b = 224 / 7
b = 32
Substitute b = 32 into (2)
3b - 4h = 24
3(32) - 4h = 24
96 - 4h = 24
-4h = 24 - 96
-4h = -72
h = -72 / -4
= 18
h = 18
Bath towels = $32
Hand towels = $18

Find the length of the hypotenuse, c in this triangle
Answer:
c = 5cm
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 3^2 = c^2
16 + 9 = c^2
25 = c^2
do the square root of 25 and c to solve for c
the square root of c^2 is c
therefore, c= 5cm

how do you solve y=3-x
2x+y=6
Answer:
x=3 y=0
Step-by-step explanation:
This is called system of innequalities
we know y= 3-x and we substitute that into 2x+y=6 and we get
2x+3-x=6 we solve and get x=3
then we substitute x into the first equation and we get y=3-3 and get 0
x=3 y=0

The height of the real table is 48 in. What is the height of the table in the scale model?
Answer:
Length of real table: 72 in
Height of scale moble table: 6 cm.
Step-by-step explanation:
Multiply the 9 cm by 8 to get the scale to full size and divide the 48 by 8 to get the scale size.
What is x?
4x(2x+6)=8x²(23-5)
pls, help for the first person to answer I will give them a brainlist.
Answer:
x= 3/17
Step-by-step explanation:
4x(2x+6) =8x^2(23-5)
8x^2 +24x = 144 x^2
24x = 136 x^2
24= 136 x
x=24/136
x=3/17
Find the measure of each interior angle.
Answer:
d) m<J = 115, m<K = 130, m<M = 50, m<N = 65
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 360
if we add all the given angles 7x + 10 = 360 subtract 10 from both sides
7x = 350 divide both sides by 7
x = 50 to find the measure of each angle replace x with 50

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?
A
1 out of 3
B
1 out of 6
с
3 out of 6
D
5 out of 6
Answer:
C) [tex]P(E) = \frac{3}{6}[/tex]
The probability that Mae will roll an odd number
[tex]P(E) = \frac{3}{6}[/tex]
Step-by-step explanation:
Step(i):-
Given that Mae has a number cube with 6 sides that are numbered 1 through 6.
n(S) = { 1,2,3,4,5,6,} = 6
Let 'E ' be the event of odd numbers
Mae will roll an odd number
n(E) = {1, 3, 5} = 3
Step(ii):-
The probability that Mae will roll an odd number
[tex]P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}[/tex]
[tex]P(E) = \frac{3}{6}[/tex]

Which value of y makes the inequality 3y^2+2(y-5)>8 true
A y=0
B y= -1
C y= -2
D y= -3
Answer:
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.
Step-by-step explanation:
Given the inequality
3y² + 2(y - 5) > 8
For y = 0
substitute y = 0 in the inequality
3y² + 2(y - 5) > 8
3(0)² + 2(0 - 5) > 8
3(0) + 2(-5) > 8
0 - 10 > 8
-10 > 8
FALSE!
-10 can not be greater than 8.
Hence, y = 0 does not make the inequality true.
For y = -1
substitute y = -1 in the inequality
3y² + 2(y - 5) > 8
3(-1)² + 2(-1 - 5) > 8
3(1) + 2(-6) > 8
3 - 12 > 8
-9 > 8
FALSE!
-9 can not be greater than 8.
Hence, y = 1 does not make the inequality true.
For y = -2
substitute y = -2 in the inequality
3y² + 2(y - 5) > 8
3(-2)² + 2(-2 - 5) > 8
3(4) + 2(-7) > 8
12 - 14 > 8
-2 > 8
FALSE!
-2 can not be greater than 8.
Hence, y = -2 does not make the inequality true.
For y = -3
substitute y = -3 in the inequality
3y² + 2(y - 5) > 8
3(-3)² + 2(-3 - 5) > 8
3(9) + 2(-8) > 8
27 - 16 > 8
11 > 8
TRUE!
11 is indeed greater than 8.
Hence, y = -3 MAKES the inequality TRUE.
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.

D

what is the length of the diagonal C
then find the length of diagonal D
Answer:
d = √389
Step-by-step explanation:
to find c we use 15 and 8 into the formula of "a^2 + b^2 = c^2" which is 17. Now we use 17 and 10 as a and b to find c in the formula which is d.
a^2 + b^2 = c^2
10^2 + 17^2 = x^2
100 + 289 = x^2
389 = x^2
√389 = √x^2
√389 = x

Step-by-step explanation:
Since its a parallelogram, opposite sides are congruent. Therefore:
BC = AD
a - 1.5 = 20.5
+1.5 +1.5
a = 22
Answer:
a=22
Step-by-step explanation:
a-1. 5 =20. 5 ( opposite side of parallelogram are equal )
or, a=20. 5+1. 5
or, a=22
you can do it from another side too.
2a-20. 8 = a + 1. 2 ( opposite side of parallelogram are equal )
or, 2a - a = 1. 2 + 20. 8
or, a = 22
