10 POINTS Solve for y: 5y + 2y -4y = 30
Answer:
10
Step-by-step explanation:
5y + 2y -4y = 30
To solve first combine like terms
5y+2y-4y=3y
Then isolate your variable, do this by dividing both sides by 3.
3y=30
3y/3=30/3
Finally, simplify
y=10

What is the slope of a line perpendicular to the line whose equation is
6x - 5y = -40. Fully reduce your answer.
Answer:
Slope = - 5/6
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
6x - 5y = - 40 Equation
Step 3:
- 5y = - 6x - 40 Subtract 6x on both sides
Step 4:
y = 5/6x - 80 Divide 5 on both sides
Step 5:
m = Slope
Answer:
Slope = - 5/6

A line has a slope of 1/4 and passes through the point (0.2. 4/5).
Find the value of b, the y-intercept.
b=
Answer:
The value of the y-intercept b is 0.75
Step-by-step explanation:
Here, we want to find the value of the y-intercept
The equation of the line can be written as;
y = mx + b
where m is slope and b is the y-intercept
so y = 1/4x + c
To get the value of b , we substitute for x and y using the given point
4/5 = 1/4(0.2) + c
Multiply
0.8 = (0.25)(0.2) + b
0.8 = 0.05 + b
b = 0.8 - 0.05 = 0.75
Answer:
b=0.75

C5.3 PA9Fitbands' estimated sales are: October $131,982 November $195,723 December $249,283 January $124,298 February $124,284 March $124, 273 What are the balances in accounts receivable for January, February, and March if 65% of sales are collected in the month of sale, 25% is collected the month after the sale, and 10% is the second month after the sale?
Answer:
Accounts receivable in January = $68,432.60
Accounts receivable in February = $55,929.20
Accounts receivable in March = $55,958.95
Step-by-step explanation:
65% of sales collected in the month of sales + 25% in the following month + 10% in second month after sales.
In January, total accounts receivable will be the amounts outstanding or unpaid by the end of January. By the end of January, a total of 10% of December sales & 35% of January sales remain outstanding.
Accounts receivable in January = 35% of January sales + 10% of December sales
Accounts receivable in January = (35% * $124298) + (10% * $249283)
Accounts receivable in January = $43504.3 + $24928.3
Accounts receivable in January = $68432.60
In February, total accounts receivable will be the amounts outstanding or unpaid by the end of February. By the end of February, a total of 10% of January sales & 35% of February sales remain outstanding.
Accounts receivable in February = 35% of February sales + 10% of January sales
Accounts receivable in February = (35% * $124284) + (10% * $124298)
Accounts receivable in February = $43,499.4 + $12,429.8
Accounts receivable in February = $55,929.20
In March, total accounts receivable will be the amounts outstanding or unpaid by the end of march. By the end of March, a total of 10% of February sales & 35% of March sales remain outstanding.
Accounts receivable in March = 35% of March sales + 10% of February sales
Accounts receivable in March = (35% * $124373) + (10% * $124284)
Accounts receivable in March = $43530.55 + $12428.4
Accounts receivable in March = $55,958.95
The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%
Answer:
C. 20%
Step-by-step explanation:
50*2=100
40*2=80
100-80=20
A percentage is a number or ratio that represents a fraction of 100.
The percentage decrease in the cost of the pair of pants is 20%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50/100 = 1/2
10% = 10/100 = 1/10
25% = 25/100 = 1/4
20% = 20/100 = 1/5
We have,
The initial cost of pair of pants = $50
The final cost of pair of pants after reduced = $40
The percentage decrease in the cost of pair of pants:
= [( Initial cost - Final cost ) / Initial cost] x 100
= [(50 - 40) / 50] x 100
= (10/50) x 100
= 20%
Thus,
The percentage decrease in the cost of the pair of pants is 20%.

Step-by-step explanation:
Given h(x)=-x-4h(x)=−x−4, solve for xx when h(x)=9h(x)=9.
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
Given [tex]h(x)=-x-4[/tex], solve for x when [tex]h(x)=9h(x)=9[/tex].
First we need to figure out what number multiplied by 9 is equal to 9. This number is 1. [tex](1*9=9)[/tex]
Therefore, we know that h(x) should be equal to 1 in order for 9 times h(x) to equal 9.
Create an equation where h(x) = 1.
[tex]h(x)=1 \\ (-x-4)=1[/tex]Solve this equation by adding 4 to both sides of the equation.
[tex]-x=5[/tex]Divide both sides of the equation by -1 to isolate x.
[tex]x=-5[/tex]Check your answer by substituting -5 for x back into the equation to make sure h(x) = 1.
[tex]-(-5) - 4 = 1[/tex]If [tex]h(x)=1[/tex], then the statement [tex]9h(x) =9[/tex] is true, verifying our answer for x is correct.

Total interest ==equals

Answer:
450
2,950
thats the answer
450 is the total interest amount and 2950 is the total amount.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the simple interest, we can use the formula:
A = P(1 + rt)
Now we can simply substitute the values given in the formula.
Before anything, it is a good practice to define the values of each variable.
P = 2,500
r = 9% or 0.09
t = 2
0.09×2500=225
225 is the interest for one year
450 is the total interest for two years.
Now we proceed to use the values in the formula to find total amount.
A=P(1+rt)
A = 2,500(1 + (0.09 × 2))
A = 2,500(1 + 0.18)
A = 2,500( 1.18 )
A = 2,950.00 Rupees
Hence, 450 is the total interest amount and 2950 is the total amount.
