Tickets for a celebrity golf tournament were sold before the tournament and on the day of the tournament. After reviewing
ticket sales, the tournament director found that 150 fewer tickets were purchased on the day of the tournament than
before the tournament. A total of 898 tickets were sold. How many tickets were sold on the day of the tournament?
Tickets sold on the day of the tournament are 374.
Suppose tickets sold before the tournament =x
So, tickets sold on the day of the tournament = x-150
What is an equation?
An equation is a statement that equates to two statements.
According to the question, the total number of tickets sold is 898.
[tex]x+(x-150)=898[/tex]
[tex]2x-150=898[/tex]
[tex]2x=1048[/tex]
[tex]x=524[/tex]
Tickets sold before the tournament =524
So, Tickets sold on the day of the tournament =524-150 = 374
Hence, Tickets sold on the day of the tournament are 374.

Use digits to write this nine hundered eighty million four hundred seventy
Answer:
980000470
Step-by-step explanation:
Write a number that makes this equation true. 4\text{ hundreds} =4 hundreds=4, start text, space, h, u, n, d, r, e, d, s, end text, equals \text{ones}onesstart text, o, n, e, s, end text
Answer:
hundreds = 1, for the equation to be true.
Step-by-step explanation:
Given an equation:
[tex]\frac{4}{hundreds}[/tex] = 4 hundreds = 4
For this equation to be true, hundreds should be represented by a minimum value.
This implies that, hundreds can not be represented by a number which equal zero, less than or greater than 1. Therefore, hundreds = 1.
So that;
[tex]\frac{4}{1}[/tex] = 4 x 1 = 4
⇒ 4 = 4 = 4
Thus, a true expression.
For the given equation to be true, hundreds must be equal to 1.
E.g: [tex]\frac{100}{hundreds}[/tex] = 100 hundreds = 100
For this equation to be true, hundreds = 1.
So that;
[tex]\frac{100}{1}[/tex] = 100 x 1 = 100
⇒ 100 = 100 = 100
Answer: 400
Step-by-step explanation:
40 times 10 is 400
Point T is on line segment \overline{SU} SU . Given TU=x-1,TU=x−1, SU=3x-7,SU=3x−7, and ST=x+7,ST=x+7, determine the numerical length of \overline{TU}. TU .
Answer:
TU = 12 units
Step-by-step explanation:
Given that T is a point on line segment SU.
So that;
SU = ST + TU
But, SU = 3x - 7, TU = x - 1, and ST = x + 7.Thus,
SU = ST + TU
3x - 7 = (x + 7) + (x - 1)
3x - 7 = x + 7 + x - 1
3x - 7 = 2x + 6
Collecting like terms.
3x - 2x = 6 + 7
x = 13
Therefore,
TU = x - 1
= 13 - 1
= 12
TU = 12 units
ST = x + 7
= 13 + 7
= 20 units
SU = 20 + 12
= 32 units

|2x+3|-5<12
Answer:
- 10 < x < 7
Step-by-step explanation:
Inequalities of the type | x | < a
Always have solutions of the form
- a < x < a
Given
| 2x + 3 | - 5 < 12 ( add 5 to both sides )
| 2x + 3 | < 17 , then
- 17 < 2x + 3 < 17 ( subtract 3 from all 3 intervals )
- 20 < 2x < 14 ( divide the 3 intervals by 2 )
- 10 < x < 7

Simon bought three plants at a nursery for $17.94. How much money would it cost for Simon to go back to the store and buy two more plants?
Answer:29.4
Step-by-step explanation:
alright so basically if he bought 3 plants for 17.94, then you just have to divide by three, like so. 17.94/3. you can do this with any calculator. now you have the original price of each plant, which is $5.98. now, multiply by two. $11.96. now add 17.94. $29.4. that is the final answer
The cost of buying two more plants is $11.98
What is a cost?Cost is a value of money that a company had to spend to produce its goods or services.
Given that, Simon bought three plants at a nursery for $17.94
Cost of 3 plants = $17.94
Cost of 1 plant = $17.94/3
Cost of 1 plant = $5.98
Cost of 2 plant = $5.98*2 = $11.96
Hence, The cost of buying two more plants is $11.98

Sam's rectangular garden measures 1 1 5 1 1 5 yards by 2 5 6 2 5 6 yards. His neighbor, Tess, has a rectangular garden that is 8 1 2 8 1 2 yards long and has a perimeter of 33 yards. What is the ratio of the area of Sam's garden to the area of Tess's garden?
Answer:
3.4 : 104.125
Step-by-step explanation:
Sam's rectangular garden measures 1 1 /5 yards by 2 5 /6yards.
Area of Sam's garden = Length × Breadth
= 1 1/5 × 2 5/6
= 3 2/5 square yards
= 3. 4 square yards
His neighbor, Tess, has a rectangular garden that is 8 1 /2yards long and has a perimeter of 33 yards.
Perimeter = 2L + 2 W
2W = P - 2L
W = P - 2L/2
W = 33 - 8 1/2/2
W = 49/2 ÷ 2
W = 12 1/4 yards
Area of Tess Garden = Length × Width
12 1/4 × 8 1/2
= 104 1/8 square yards
= 104 .125 square yards
What is the ratio of the area of Sam's garden to the area of Tess's garden?
= Sam : Tess
= 3.4 : 104.125

SASΔRTS ≅ ΔRTUStep-by-step explanation:
The two triangles share a side, so that side will be both corresponding (to itself) and congruent (to itself). The two marked sides are congruent, as are the angles at the point of intersection (T) between the shared side and the marked sides.
So, we have congruent sides with a congruent angle between them. The SAS theorem applies to this situation. As we noted, side RT corresponds to itself. The third vertices of each triangle also correspond, so the congruence statement can be written ...

[tex]T = \frac{I}{PR}[/tex]
Step-by-step explanation:
Given
[tex]I = PRT[/tex]
What the question implies is that, we make T the subject of formula.
In other words, solve for T
We have that:
[tex]I = PRT[/tex]
Divide both sides by PR
[tex]\frac{I}{PR} = \frac{PRT}{PR}[/tex]
[tex]\frac{I}{PR} = T[/tex]
Reorder
[tex]T = \frac{I}{PR}[/tex]
