. How many yellow flowers did Lamar plant?
Answer:
I think its 31
Step-by-step explanation:
because the ratio was 25/56 of orange flowers,
so the rest of them are yellow
plss answer it is so important
Answer:
1. (100-5) × (100+3) = 10000 + 300 - 500 - 15
=> 10300 - 515 = 9785
2. (500+1) × (500+2) = 250000 + 1000 + 500 + 2
=> 251502

Find the value of x. Give reasons to justify your solution-
Answer:
x = 34
Step-by-step explanation:
∠ PSR and ∠ TSU are vertical angles and congruent, then
∠ PSR = 4x, thus ∠ PSQ = x
The exterior angle of a triangle is equal to the 2 opposite interior angles.
∠ SQR is an exterior angle of Δ PQS , thus
x + x = 68
2x = 68 ( divide both sides by 2 )
x = 34
Answer:
X = 34°
Step-by-step explanation:
In order to solve this question we will need to know the following, when two lines intersect the opposite angles at that point are equal to each other, that the sum of all angles of a triangle is 180 degrees, and that the angle of a straight line is equal to 180 degrees.
Frist we will have to notice that ∠TSU is equal to ∠PSR, because they are opposite to each other (If you would like to understand this more you can research on a topic call "vertical angels"). Now it is important to understand the following.
∠PSR = ∠PSQ + QSR
Since ∠PSR = ∠TSU = 4x, ∠QSR = 3x ⇒
⇒ ∠PSR = ∠PSQ + QSR
4x = ∠PSQ + 3x
4x - 3x = ∠PSQ
x = ∠PSQ
Now, since the sum of all angles in a triangle is equal to 180 we can now say the following:
∠QPS + ∠PSQ + ∠PQS = 180°
In order to find out what PQS is equal to we need to use our knowledge about the angel of a strait line (the angel of a strait line is equal to 180°).
So now we can say the following:
180° = ∠PQS + SQR
∠PQS = 180° - ∠SQR
Since we know that ∠SQR = 68° ⇒
⇒∠PQS = 180° - ∠SQR
∠PQS = 180° - 68°
∠PQS = 112°
Since ∠QPS = x, PSQ = x, and ∠PQS = 112° ⇒
⇒ ∠QPS + ∠PSQ + ∠PQS = 180°
x + x + 112° = 180°
2x = 180° - 112°
2x = 68°
x = 34°

Suppose that you own a compact car
that you bought new for 18,000 dollars.
The value of this particular make of car is
known to depreciate at a rate of 20%
per year.
Define a unit for each quantity in the
worksheet. Then enter a variable for
the time since you bought the car new
Answer:
Depreciation and Written Down Value for first 5 years of purchase is explained.
Step-by-step explanation:
The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.
Declining Method
Year 1
$18,000 * 20% = $3,600 Depreciation
$18,000 - $3,600 = $14,400 Written Down Value WDV
Year 2
$14,400 * 20% = $2,880 Depreciation
$14,400 - $2,880 = $11,520 WDV
Year 3
$11,520 * 20% = $2,304 Depreciation
$11,520 - $2,304 = $9,216 WDV
Year 4
$9,216 * 20% = $1,843 Depreciation
$9,216 - $1,843 = $7,373 WDV
Year 5
$7,373 * 20% = $1,475 Depreciation
$7,373 - $1,475 = 5,898 WDV

y=5x-9
y=3x+7
Answer:
Step-by-step explanation:
x and y are variables. That means they represent numbers that are unknown. When we solve for x or y, we are trying to find what number the variable represents.
Y is a number that equals both 5x-9 and 3x+7. If it is a number, it can only have one value, so we can say that 5x-9 and 3x+7 have the same value.
In other words, 5x-9 = 3x+7.
Another way of thinking about this step is substitution. y=3x+7, so in the equation y=5x-9, we can replace the y with 3x+7. It will give 3x+7 = 5x-9.
In either case, we have this new equation
5x-9 = 3x+7.
From here it's just simple algebra- subtract 3x from each side
2x -9 = 7
and add 9 to each side
2x = 16
and divide each side by 2.
x = 8.
All these steps work because if two things equal each other, when you do the same thing to both of them (such as add 9), the new values will still equal each other.
Now that we know that x = 8, we can take one of the original equations
y=5x-9
and put 8 in for x.
y=5*(8) -9.
If x represents the value 8, we can obviously switch out x for 8.
Now simplify
y=40 -9
y = 31
Now we know that x = 8 and y = 31.
Answer:
x=8 and y=31
Let's solve your system by substitution.
y=5x−9;y=3x+7
Step: Solve y=5x−9for y:
y=5x−9
Step: Substitute5x−9foryiny=3x+7:
y=3x+7
5x−9=3x+7
5x−9+−3x=3x+7+−3x (Add -3x to both sides)
2x−9=7
2x−9+9=7+9(Add 9 to both sides)
2x=16
2x/2=16/2 (Divide both sides by 2)
x=8
Step: Substitute 8 for x in y=5x−9:
y=5x−9
y=(5)(8)−9
y=31 (Simplify both sides of the equation)
Answer:
x=8 and y=31

WHO WANTS BRAINLIESTT ?????? PLEASE answer this question correctly !!!! STEP BY STEP !!!!!!!!!!!!!!!
Answer:
x = 45
y = 60
Step-by-step explanation:
2x = 90
2x (1/2) = 90 (1/2)
x = 45
3y - 2y = 90
3y - 2(45) = 90
3y - 90 = 90
3y - 90 (+90) = 90 (+90)
3y = 180
3y (1/3) = 180 (1/3)
y = 60
Hope this helps :)

Express this number in scientific notation. 0.15880.1588
Answer: 1.588×10−1 (The negative one is small on the top right of the 10)
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Angelo grows vegetables and sells them at a farmers'
market. The price of 2 cucumbers and I pepper is
$3.15, and the price of 3 cucumbers and 2 peppers is
$5.35. Based on this pricing, what would be the price,
in dollars, of 4 cucumbers and 3 peppers?
Answer:
$7.55
Step-by-step explanation:
We can solve this by using a system of equations. The equations would be set up like this:
[tex]2c + p = 3.15\\3c + 2p = 5.35\\[/tex]
Let's isolate a variable in the first equation:
[tex]p = -2c + 3.15[/tex]
Now we can plug this in to the second equation:
[tex]3c + 2(-2c + 3.15) = 5.35\\3c - 4c + 6.3 = 5.35\\-c + 6.3 = 5.35 \\-c = -.95\\c = .95[/tex]
Now that we have found c we can find p by plugging c in to an equation
[tex]2(.95) + p = 3.15\\1.9 + p = 3.15\\p = 1.25[/tex]
We have found both variables now we can use the following equation to answer the question:
[tex]4c + 3p = ?\\4(.95) + 3(1.25) = ?\\3.8+3.75 = 7.55[/tex]
Therefore, the price in dollars of 4 cucumbers and 3 peppers is $7.55.
I hope this helps!!
