Answer: She had left 54% of the money which is $1620.
Step-by-step explanation:
40% of $3000 = $1200
15% of $1200 = $180
$3000 - ($1200 + $180)
$3000 - $1380 = $1620
$1620 is the money she had left.
$1620 is 54% of $3000
She had 54% left of the money.

3x + 2 6x - 20
Step-by-step explanation:
Remember that the sum of angles on a straight line are supplementary. (180°)
Therefore 3x + 2 + 6x - 20 = 180.
=> 9x - 18 = 180
=> 9x = 198
=> x = 22.

5. Lines s and t intersect as shown in the picture. Which pair of angles are vertical?
A. angle 7 and angle 10
B. angle 9 and angle 10
C. angle 8 and angle 10
D. angle 7 and angle
Answer: angle 7 and angle 10
Step-by-step explanation: trust me its correct
Answer:
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.

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?
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
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.
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.
I need help on a slope problem to fine the slope of the line
Answer:
Okay what's the problem?
Step-by-step explanation:
Answer:
if you are given two points, use the equation y2-y1 / x2-x1
if you are given a graph, use rise/run
Step-by-step explanation:
if you have two points, like (4,5) and (6,9), take the second numbers of both pairs (the ys) and subtract them from each other (usually 2nd y minus 1st y), so with these points I would do 9-5
then subtract the first numbers of both pairs (the xs) from each other too (just like the ys: 2nd x minus 1st x), so with these points I would do 6-4
now you have y=9-5 which is 4
and x=6-4 which is 2
now you put 4/2 and simplify it to get 2
so your slope with these points is 2
if you want to find slope on a graph, look at where the line crosses the x/y axis lines, the points where they meet, and look at the distance between each point that it crosses
to find the slope put the rise (vertical change in y between each point) over the run (horizontal change in x between each point) in a fraction like this
rise/run
simplify that and you have your slope

Find the values of a and b such that x^2-2x+2=(x-a)^2+b
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

.. At a football game, there were 4 times as many fans for the home team as there were for the visiting team.
What was the ratio of home-team fans to visiting team fans?
This is ratios
Answer:4
Step-by-step explanation:
Given
Home team fans are 4 times the visiting team fans
Suppose there are x visiting fans
So, home team fans are 4x
The ratio of home-team fans to visiting team fans = [tex]\frac{4x}{x}=4[/tex]
Can you anser number 9
Answer:
[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]

What is the value of X what is the measure of 2 PLEASE HELPPP
Answer:
x = 11 , m∠2 = 31
Step-by-step explanation:
We know that m∠1 is equal to both 6x+8 and 74
Therefore, 6x+8 = 74
And 6x = 66
x = 11
To find m∠2, we just plug in the value of x that we got earlier
(7x-2) + m∠2 = 106
(77-2) + m∠2 = 106
m∠2 = 31
Claire is building a dollhouse where 1 inch on the plans is equivalent to 5 inches on the actual dollhouse.
If the house is to be 32.5 inches tall, what will the height be on the plans?
Answer: 6.5 inches
Step-by-step explanation:
From the question, we are informed that Claire is building a dollhouse where 1 inch on the plans is equivalent to 5 inches on the actual dollhouse.
If the house is to be 32.5 inches tall, the height be on the plans will be one-fifth of the actual dollhouse. This will be:
= 1/5 × 32.5
= 6.5 inches

Jason and his children went into a grocery store and will buy bananas and mangos. Each banana costs $0.90 and each mango costs $2. Jason has a total of $25 to spend on bananas and mangos. Write an inequality that would represent the possible values for the number of bananas purchased, bb, and the number of mangos purchased, m.m.
Answer:
25 ≥ 0.90b + 2m
Step-by-step explanation:
Given:
Cost of each banana = $0.90
Cost of each mango = $2
Total amount = $25
Find:
Inequality
Computation:
Assume;
Number of banana = b
Number of mango = m
Total amount ≥ Cost of total banana + Cost of total mango
25 ≥ 0.90b + 2m
