Answer:
510
Step-by-step explanation:
510 adults can ride a bike out of 600.
We can do this by first taking 15% of 600. To calculate 15% of 600, simply divide the percent (in this case, 15) by 100 and multiply by the number (600). For example, 15 ÷ 100 x 600 = 90, which means the same as 0.15 x 600 = 90.
Now that we know how many adults can't ride a bike, we take 600 and subtract that number from it. So, 600 - 90 = 510, which is how many adults can ride a bike.
Hope this helped! :)
How can you solve one-step multiplication and division equations?
Answer:
Step-by-step explanation:
All of these equations only require a single operation before you get x alone. for example: x - 2 = 6 Compared with 2x = 6
For the first one, you have to add two and get x = 8. for the second one, Then you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.
Critique the the reasoning of others. Connor determines the slope between (-2,4) and (3,-3) by calculating 4 -(-3)/ -2 - 3. April determines the slope by calculating 3 - (-2) / -3 - 4. Explain whose reasoning is correct.
Answer:
Connor's
Step-by-step explanation:
According to the slope formula, it is (y2 - y1)/(x2 - x1)
Connor uses the y-values first and put them on the numerator, and that is what you are meant to do, unlike, April. She puts the x-values on top and the y-values on the bottom.

does a chemical change create a new substance?
Answer:
True
In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”

Miranda and Jean are planning a trip together. They want to drive, but they're not sure whose car to take. Jean's car uses 5/12 gallons of gasoline to travel 12 1/2 miles. Miranda's car can go 20 5/7 miles on 5/7 gallons of gasoline. Whose car is more fuel efficient, and what is the car’s fuel efficiency in miles per gallon?
Answer:
most fuel efficient is Jean's car....it gets 30 miles per gallon
Step-by-step explanation:
Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
The Spanish club held a car wash to raise money why equals Y=5X represents the amount of money The Y club members made Washing cars identify the constant Proportionality
Given:
The amount of money y club members made for washing x cars is
[tex]y=5x[/tex]
To find:
The constant Proportionality.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.

4x+2=4 if x satisfies the equation above, what is the value of 2x+1
Answer:
2
Step-by-step explanation:
4x + 2 =4 => 4x = 2 => x = 0,5
if x =0,5 => 2x + 1 = 0,5.2 + 1 = 2
The values of "2x+1" will be "2".
The expression,
→ [tex]4x+2=4[/tex]
By subtracting "2" from both sides, we get
→ [tex]4x+2-2=4-2[/tex]
→ [tex]4x=2[/tex]
→ [tex]x = \frac{2}{4}[/tex]
→ [tex]x = 0.5[/tex]
By putting the value of "x" in the expression "2x+1", we get
→ [tex]2x+1 = 2(0.5)+1[/tex]
→ [tex]= 1+1[/tex]
→ [tex]= 2[/tex]

Suppose that you decide to buy a car for $57,000, including taxes and license fees. You saved $10,000 for a down payment. The dealer is offering you a choice between two incentives. Incentive A is $5000 off the price of the car, followed by a four-year loan at 6.06%. Incentive B does not have a cash rebate, but provides free financing (no interest) over four years. What is the difference in monthly payments between the two offers? Which incentive is the better deal? Use PMT= P r n 1−1+ r n−nt. The difference in monthly payments between the two offers is $nothing. (Round to the nearest cent as needed.)
Answer:
Following are the solution to this question:
Step-by-step explanation:
For incentive A
The car value = 57000
Calculating debt[tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the debt value after incentive [tex]= 47000 - 5000[/tex]
[tex]= 42000[/tex]
[tex]PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}[/tex]
[tex]= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}[/tex]
[tex]= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89[/tex]
For incentive B
The car value = 57000
Calculating the debt value [tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the monthly payment =[tex]\frac{47000}{(12*4)}[/tex]
[tex]= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166[/tex]
difference:
[tex]=121.89 - 979.166\\\\ = - 854.276[/tex]

A line passes through the point (8,-1) and has a slope of -3/2
Answer:
y = -3/2 x +11Step-by-step explanation:
[tex](8,-1) = (x_1,y_1)\\\\m = -\frac{3}{2}[/tex]
Substitute values into point-slope form
[tex]y-y_1=m(x-x_1)\\\\y -(-1)=-\frac{3}{2} (x -8)\\\\y+1 = -\frac{3}{2}x+12\\\\y = -\frac{3}{2}x +12-1\\\\y =-\frac{3}{2}x +11[/tex]
The equation of line passes through the point (8, -1) will be;
⇒ y = - 3/2x + 11
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (8, - 1).
And, The slope of the line is,
⇒ m = - 3/2
Now,
Since, The equation of line passes through the point (8, -1).
And, Slope of the line is,
⇒ m = - 3/2
Thus, The equation of line with slope - 3/2 is,
⇒ y - (-1) = - 3/2 (x - 8)
⇒ y + 1 = - 3/2 (x - 8)
⇒ y + 1 = - 3/2x + 12
⇒ y = - 3/2x + 12 - 1
⇒ y = - 3/2x + 11
Therefore, The equation of line passes through the point (8, -1) with slope - 3/2 is,
⇒ y = - 3/2x + 11
