Answer:
Is this what you meant?
(2x + 3x) × (3 + 15) = 12x + 36
(5x) × (18) = 12x + 36
90x = 12x + 36
78x = 36
x = 36 / 78
x = 18 / 39
_____________________
or
3(2x+3x) + 15 = 12x + 36
10x + 15 = 12x + 36
-21 = 2x
2x = -21

A basketball stadium has 15 ,002 zero seats the lower level has 54 than three times as many seats as the upper level the middle level has 40 more than twice as many seats as the upper level used to solve for x and found that the upper level has 2,502 sears
Answer:
There are 7456 seats on the lower level and there are 5044 seats on the middle level.
Step-by-step explanation:
Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...
# of seats on the lower level = 3x - 50
# of seats on the lower level = 3(2502) - 50
# of seats on the lower level = 7456
Now we just make the equation for the number of seats on the middle level, and so we get...
# of seats on the middle level = 2x + 40
# of seats on the middle level = 2(2502) + 40
# of seats on the middle level = 5044

Kallisto built a rectangular sign that measured 2 and 3/4. The width is 1 and 1/4 shorter than the length. To find the area, multiply the length and width. What is the area in square feet write an equation to solve it
Answer:
l = 1 5/16
w = 1/16
A = 21/16 x 1/16 = 21/256
Step-by-step explanation:
Perimeter = 11/4
l = length
w = l - 5/4
2l + 2(l - 5/4) = 11/4
2l + 2l - -5/2 = 1/4
multiply each side by 4
8l + 8l - 10 = 11
16l = 21
l = 21/16 or 1 5/16
width = 21/16 - 20/16 = 1/16
The bike Razi wants to buy costs
$250. He babysat 4 times for a total of 15
hours. He has also mowed the lawn 5 times.
Has he earned enough money to buy the
bike?
Answer:
Not enough information
Step-by-step explanation:
So, we first know that the bike costs 250 dollars. We also know that he babysat for 15 hours, and mowed the lawn 5 times. However, we do not know how much money he has, or how much he made. Sure, doing extra chores could of made him money, but in this question it doesn't say how much money he made. Therefore, we cannot answer this question because, although we have the value of the bike's cost, we do not know how much Razi has. Hope this helps you!

Solve the right triangle. Round decimal answers to the nearest tenth.
The main question isn't supplied.
Answer:
Kindly check explanation
Step-by-step explanation:
A right - angled triangle is one which has one of its angles being 90°. Once we have a right angled triangle, the rule of Pythagoras can be applied in other to solve problems relating to obtaining sides of the triangle while trigonometric relations including :
Sinθ = opposite / hypotenus
Tanθ = opposite / Adjacent
Cosθ = Adjacent / Hypotenus
To obtain the angle θ; depending on which of the sides are given.
From Pythagoras :
c² = a² + b²
Where, c = hypotenus and the longest side if the triangle.

To model some data, Anne ran a linear regression and found the regression equation to be y=0.554x-0.507.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]y = 0.554x - 0.507[/tex]
The question is incomplete; however, a possible question could be to interpret the given equation.
The equation is given in slope intercept form i.e. [tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
[tex]b = y\ intercept[/tex]
So, by comparing:
[tex]y = mx + b[/tex] to [tex]y = 0.554x - 0.507[/tex]
[tex]m = 0.554[/tex]
[tex]b = -0.507[/tex]
Hence, the slope of the regression is 0.554 and the y intercept of -0.507

3(g + 4) = 9
Need help
Answer:
g=-1
Step-by-step explanation:
3(g+4)=9
Divide both sides by 3.
g+4= 9/3
Divide 9 by 3 to get 3.
g+4=3
Subtract 4 from both sides.
g=3−4
Subtract 4 from 3 to get −1.
g=−1
Answer:
3(g+4)=9
or, 3(g+4)/3=9/3 [Dividing both sides by 3.]
or, g+4=3
or, g+4-4=3-4 [Subtracting 4 from both sides.]
So, g=-1

24. The population of Bayside, CA increased from 23,560 in 1990. The annual rate of
population increase for the next 20 years was about 6%. Predict the population of Bayside in
2010.
Answer:
the population in 2010 is 75,656.33
Step-by-step explanation:
Given that
The increase in population in the year 1990 is 23,560
The Annual rate of interest is 6%
And, the time period is 20 years
We need to find out the population in 2010
So, the following formula should be used
= Population × (1 + rate)^time period
= 23,590 × (1 + 0.06)20
= 23,590 × 1.06^20
= 75,656.33
hence, the population in 2010 is 75,656.33

In the figure below,the segments JK and JL are tangent to the circle centered at O.Given that JL =13.2 and OJ=16.5,find OK.
Answer:
OK=9.9
Step-by-step explanation:
KJ and LJ both are on the circumference, are secants and coincides at the same outer point so they are equal.
JK=LJ so JK=13.2
Tangents are perpendicular to radius so the triangle in the circle is a right triangle.
Apply pythagorean theorem to find OK
[tex] {x}^{2} + 13.2 {}^{2} = 16.5 {}^{2} [/tex]
[tex]x = 9.9[/tex]
You use 7 1/2 c flour to make 3 loaves of bread. The second person uses the same recipe. He will make b loves of bread using f cups of flour. Write an equations that represents of the relationship between b and f.
Answer:
b = 2/5f
Step-by-step explanation:
Cups of flour = loaves of bread
7 1/2 c = 3
c = 3 ÷ 7 1/2
c = 3 ÷ 15/2
= 3 × 2/15
= 6/15
= 2/5
c = 2/5
Cups of flour = loaves of bread
2/5 f = b
b = 2/5f
