Shelia buys flower bulbs from a catalog $2 each and $4 shipping charge for the whole order. She spends $20 on flower bulbs. The model can be used to describe x, the number of bulbs Shelia can order. Write an equation to determine the number of bulbs Shelia can order. How many bulbs did she order?
Answers
Answer:
8 bulbs
Step-by-step explanation:
Step one:
Given data
Shelia buys flower bulbs from a catalog for $2 each and $4 shipping charge for the whole order
we are told that the total money spent is $20
let the number of bulbs ordered be x, and the total money spent be y
the equation for the situation is
y=2x+4
for a total amount of $20, we want to find x
20=2x+4
20-4=2x
16=2x
divide both sides by 2
x= 16/2
x= 8 bulbs

[tex]x = \frac{367}{3}[/tex]
[tex]y = \frac{173}{3}[/tex]
Step-by-step explanation:
Equations
Let's call
x = measure of angle 1
y = measure of angle 2
The angles are supplementary, thus their sum is 180°:
x + y = 180 [1]
It's also known that one angle (x) is 7° more than twice the other (y), thus:
x = 7+ 2y [2]
Substituting [2} in [1]:
7+ 2y + y = 180
Operating:
7+ 3y = 180
Subtracting 7:
3y = 180 - 7 = 173
Dividing by 3:
[tex]y = \frac{173}{3}[/tex]
And:
[tex]x = 7+ 2*\frac{173}{3}[/tex]
[tex]x = \frac{367}{3}[/tex]

Write an inequality that would represent the possible values for the number of bananas purchased, bb, and the number of mangos purchased, m.m.
Answers
Answer:

Answer:
[tex]\huge\boxed{2329 \ \text{pounds}}[/tex]
Step-by-step explanation:
In order to solve this equation, let's see what we already know.
We know two points on the graph which we can use to find the slopeThat's about it.
However, this can come useful to find the slope between the two points, which is the slope for the entire graph (since this is linear). The slope between two points is usually defined as [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Our two points are (18, 2017) and (48, 2212).
The change in y between our two points is [tex]2212-2017 = 195[/tex], and the change in x is [tex]48 - 18 = 30[/tex]. Our slope will then be [tex]\frac{195}{30}[/tex], which comes out to be approximately 6.5. Therefore, our slope is 6.5.
Now that we know the slope, we can substitute inside our equation in slope intercept form.
[tex]y = 6.5x+b[/tex]
We have yet to find b, the y-intercept (how much the plane itself weighs). To find b, we can substitute a point on the graph into the equation and solve for b. We know that the point (18, 2017) is on the graph so let's use that.
[tex]2017 = 6.5 \cdot18 + b[/tex] [tex]2017 = 117 + b[/tex] [tex]1900= b[/tex]Now that we know our y-intercept is 1900, we can create our equation by using the slope and the y-intercept.
[tex]y=6.5x+1900[/tex]
Finally, to find the weight of the plane with 66 pounds of fuel, we can substitute 66 inside this equation as x.
[tex]y = 6.5 \cdot66+ 1900[/tex] [tex]y = 429+1900[/tex] [tex]y=2329[/tex]So the plane weighed 2329 pounds with 66 gallons of fuel.

Step-by-step explanation: trust me its correct

The right answer is 9 and 10. It is not 7 and 10 because if you can see one of the arrows for 10 is shorter than the arrow next to it for angle 7.
9 and 10 have one straight line that it is on than both share the short arrow.

Find the values of a and b such that x^2-2x+2=(x-a)^2+b
Answers
Answer:
a = 1, b = 1
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms on both sides, that is
right side
(x - a)² + b ← expand factor using FOIL
= x² - 2ax + a² + b
Compare to left side x² - 2x + 2
Compare the coefficients of the x- term
- 2a = - 2 ( divide both sides by - 2 )
a = 1
Compare the constant terms
a² + b = 2 ( substitute a = 1 )
1² + b = 2
1 + b = 2 ( subtract 1 from both sides )
b = 1
Thus a = 1, b = 1

48, 48, 50 is 40 then find value of
X
Answers
Answer:
35
Step-by-step explanation:
If the median of data (arranged in ascending order) 31,33,35,x,x+10,48,48,50 is 40,then find value of x.
Solution:
The median of a data is the middle number after the numbers from the data have been arranged either from least to greatest or from greatest to least. For an even number of data, the median is the average of the middle two numbers.
The data arranged in ascending order is:
31,33,35,x,x+10,48,48,50
SInce the data has an even number (8), the median is the average of the middle two numbers.
Median = average of x and x + 10
[x + (x + 10)] / 2 = median
[x + (x + 10)] / 2 = 40
x + x + 10 = 80
2x + 10 = 80
2x = 70
x = 70/2
x = 35

The straight line 2x + 3y = 7 meets the curve
xy + 10 = 0 at the points P and Q. Calculate the
gradient of the curve at P and at Q.
Answers
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.
