Answers
Answer:
9 + 4x = 101
Step-by-step explanation:
9 + 4x = 101 Equation
( +9 - 9 ) + 4x = ( 101 - 9 ) Subract 9 on both sides

. Alex bought a new bike last weekend. It was $185 and he had to pay tax at a rate of 8%. How
much tax did he pay?
Answers
Answer:
$14.80
Step-by-step explanation:
Original bike price: $185
Tax: 8% OR 0.08 as a DECIMAL
To find your answer, multiply the bike price by the DECIMAL (number) tax amount:
185 x 0.08
= 14.8
Therefore, Alex paid $14.80 in tax.
Answer: $14.80
Step-by-step explanation:
We know: The bike is $185, and the tax is 8% of the product.
So we multiply them together.
185 * 8 / 100 = 14.8
or
185 * 0.08 = 14.8
The tax will be $14.80.
The other way to solve this question is by cross multiply.
[tex]\ \frac{x}{185} = \frac{8}{100}\[/tex]
But what you get would still be the same as just multiply it directly.
185*5/100 = 14.8

There are oranges that are ¥90 and apples that are ¥150.
When you buy a total of 15 of them, your total cost is ¥1890.
How many oranges and apples did you buy?
Answers
Step-by-step explanation:
If 15 oranges were bought,
the total cost would be 15 * ¥90 = ¥1350.
¥1890 - ¥1350 = ¥540.
For every orange that switches to an apple,
the cost increases by ¥150 - ¥90 = ¥60.
Number of apples = ¥540 / ¥60 = 9.
Therefore there are 6 oranges and 9 apples.
Answer:
6 oranges and 9 apples.
Step-by-step explanation:
Let the number of oranges be x then the number of apples = 15 - x.
So 90x + 150(15 - x) = 1890
90x - 150x + 2250 = 1890
-60x = -360
x = 6
and number of apples = 15 - 6
So it's 6 oranges and 9 apples.

WRITE AND SOLVE AN INEQUALITY!!!!!! (people just solve without an inequality!)
Answers
98% of 25,000 is 24,500.
So from this, we can make the inequality:
25,000 - 500x
x = 5 days.
May I have brainliest please? :)
Answer:
500
Step-by-step explanation:
At least means 25000 and bigger. But 25000 is included in the inequality.
You should write an inequality to to represent the number of pieces of luggage
x ≥ 25000
100% - 98% = 2%
2% of all luggage lost is never found. Multiply both sides of x ≥ 25000 by 2%
2 percent x ≥ 25000 * 2%
2 percent x ≥ 500
Note that 2 percent is not an algebraic variable. 2% is. 2% = 2/100, but that is not what you want on the left.

The rate of change for the given function is 2.25. Therefore, option B is the correct answer.
What is rate of change of a function?The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.
From the given table, we have (1, 4.5), (2, 6.75), (3, 10.125) and (4, 15.1875).
Using coordinate points (1, 4.5) and (2, 6.75), we get
Rate of change = (6.75-4.5)/(2-1)
= 2.25
Therefore, option B is the correct answer.

cost price = $60,000
profit
= 15%
= 15% × cost price

What is the rule used to reflect the triangle ABC to its image?
A. Reflect over y = -x
B. Reflect over y = x
C. Reflect over the x axis
D. Reflect over the y-axis
Answers
Answer:
The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y) If the point (x, y) reflected across the y-axis , then its image is (-x, y) If the point (x, y) reflected across the line y = x , then its image is (y, x) If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)From the given figure
∵ The coordinates of point A are (-4.5, 6)
∵ The coordinates of point A' are (6, -4.5)
→ The coordinates are switched ⇒ 3rd rule
∴ Point A is reflected over the line y = x
∴ Δ ABC is reflected over the line y = x
∴ The rule used to reflect Δ ABC to its image is Reflect over y = x
Note: Point B' on the graph should be C' and point C' should be B' (correct it)

Four intersecting lines, t, v, u, and w, are shown in the diagram.
Answers
===============================================
Explanation:
Line w and line t are parallel if and only if the corresponding angles (4x+60) and (9x) are congruent.
9x = 4x+60
9x-4x = 60
5x = 60
x = 60/5
x = 12
If x = 12, then
9x = 9*12 = 108
4x+60 = 4*12+60 = 48+60 = 108
Both corresponding angles would be 108 degrees if x = 12. So this confirms we have the right x value.

Daryl biked for 12 minutes and traveled 1.6 miles. If He kept the same pace, how far would he travel in 3.5 hours? please show work if possible!!!!
Answers
Answer:
27.999999993 or 27.9 or 28 (rounded) miles.
Step-by-step explanation:
Find out how many miles he goes every minute.
(1.6 ÷ 12 = 0.13 recurring (0.1333333333)
3.5 hours = (60 × 3) + 30 = 210 minutes
Multiply 0.13 recurring (0.1333333333) by 210 mins.
210 × 0.13 recurring (above number) = 27.999999993 (You can round this up to the nearest whole number), which is 28 if the question asks you to but as it uses 1.6 miles, you can leave it as 27.9 or even leave the long decimal if you're not entirely sure.
Hope this helps. :)
Is it sometimes,never, or always that An integer is less than its opposite
and greater than 0.
Answers
Answer:
Sometimes
Step-by-step explanation:
SOMETIMES, An integer is less than its opposite and greater than 0.
This is because a negative integer has a positive opposite, hence a negative integer will be less than its opposite.
However, a positive integer also has a negative opposite so it will be greater than its opposite.
For example, a negative integer of -5 is less than a positive integer of 5 which is it's opposite and at the same time, a positive integer of 5 is greater than its opposite which is negative integer of -5.
Also, even though a positive integer is greater than 0, a negative integer on the other hand is less than 0

Answer: He is not correct. The resulting will be in a different quadrant.
Step-by-step explanation: This would be much easier to answer with a screen shot of the image.
For example, if the original image is in quadrant 1, the first reflection over the x-axis places the new image in quadrant 4, "upside-down" and the second reflection over the y=x line places the new image in quadrant 2 and "oblique" to the original.
Reflecting the original over the y=-x line places the new image in quadrant 3.
