Eight more than the product of a number and 3 equals 9.
Answer:
3n + 8 = 9
Step-by-step explanation:
"eight more" represents adding 8, so +8
"product of a number and 3" represents multiplying n by 3, so 3n
"equals 9" means that 3n + 8 = 9
Answer:
n = 1/3
Step-by-step explanation:
n = a number
8 + 3n = 9
3n = 1
n = 1/3
Marie is sorting pencils into boxes. She put 2 pencils in the first box, 10 pencils in the second box, 50 pencils in the third box, and 250 pencils in the fourth box. What kind of sequence is this?

Tobias Gold sells computers at The Office Center.
He is guaranteed a minimum salary of $1,959 per month plus
6.3% commission on total sales. How much in total sales does
he need in order to have a gross pay for the month of $2,784.84?
Answer:
Total sales to be made = $13108.57
Step-by-step explanation:
Given that:
Monthly salary = $1959
Commission = 6.3%
Monthly pay to be earned = $2784.84
Commission amount = 2784.84 - 1959 = $825.84
Let,
x be the amount of sales
6.3% of x = 825.84
[tex]\frac{6.3}{100}x=825.84\\0.063x=825.84[/tex]
Dividing both sides by 0.063
[tex]\frac{0.063x}{0.063}=\frac{825.84}{0.063}\\x=13108.57[/tex]
Hence,
Total sales to be made = $13108.57

Mary and Darryl are selling flower bulbs for a school fundraiser. Customers can buy bags of
windflower bulbs and bags of daffodil bulbs. Mary sold 10 bags of windflower bulbs and 4
bags of daffodil bulbs for a total of $226. Darryl sold 6 bags of windflower bulbs and 4 bags of
daffodil bulbs for a total of $166. What is the cost each of one bag of windflower bulbs and
one bag of daffodil bulbs?
Answer:
15 windflower bulbs
19 daffodil bulbs
Step-by-step explanation:
Given
Represent windflower with W and daffodil with D.
So:
Mary's sales is:
10W + 4D = 226 --- (1)
Darryl's sales is:
6W + 4D = 166 ---- (2)
Required
Solve for W and D
We'll make use of elimination method.
Start by subtracting (2) from (1)
10W - 6W + 4D - 4D = 226 - 166
4W = 60
Multiply both sides by ¼
¼ * 4W = 60 * ¼
W = 60 * ¼
W = 15
Substitute 15 for W in (1)
10W + 4D = 226
10 * 15 + 4D = 226
150 + 4D = 226
Collect like terms
4D = 226 - 150
4D = 76
Multiply both sides by ¼.
¼ * 4D = 76 * ¼.
D = 19

Identify the value of a if
y= ax+ 7x + 2
and the point (2, 12) is on the graph.
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: [tex]12=a*2+(7*2)+2[/tex]
Then, solve:
[tex]12=a*2+14+2[/tex]
a = -2
So yes, they're on the graph.
Hope this helped! :)
solve 3(6b-1)-7(2b+3)=0
Answer:
24/13 or 1.8
Step-by-step explanation:
27b -3 - 14b -21 = 0
13b - 24 = 0
13b = 24
b = 24/13 or 1.8
Answer:
B = 6
Step-by-step explanation
1. (Do the parentheses) 3(6b-1)-7(2b+3) = 18b-3-14b-21
2. (Simplify) 18b-3-14b-21 = 4b-24
3. (Add 24 to both sides) 4b-24+24=0+24
4. (Simplify) 4b = 24
5. (Divide by 4) b = 6

if the volume if a cylindrical solid is 1320 and base area is 264 . find its height
Answer:
5
Step-by-step explanation:
V = h*A where h is the height and A is the base area
1320 = h*264
Therefore, h = 5
pls answer with steps
Answer:
1.) (x - 13)(x - 8)
2.) x(x - 11)(x + 13)
3.) (x - 2)(x - 4)(2x + 1)
4.) (3x + 2)(3x - 1)
5.) (x - 4)(3x + 13)
Step-by-step explanation:
1.) (x² - 13x - 9x + 117) + (x - 13)
2.) x(x² + x - 132) + x(x - 11)
= x(x + 12)(x - 11) + x(x - 11)
= x(x - 11)(x + 13)
3.) (2x³ - 12x² + 16x) + (x -2)(x -4)
= 2x(x² - 6x + 8) + (x -2)(x - 4)
= 2x(x² - 4x - 2x + 8) + (x -2)(x -4)
4.) 9x² - 4 + (3x + 2)
= (3x)² -2² + (3x + 2)
= (3x + 2)(3x - 2) + (3x + 2)
5.) (3x² - 48) + (x - 4)
= 3(x - 4)(x + 4) + (x - 4)

4u+3u+21=70 find the value of the variables
Answer:
u=7
Step-by-step explanation:
First, add 4u and 3u because they are like terms.
7u+21=70
Second, subtract 21 from both sides.
7u=49
Finally, to isolate the variable divide 7 from both sides.
u=7

how to find the circumferenceof a circle
Answer:
You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point.
Step-by-step explanation:
Answer:
C=2[tex]\pi[/tex]r
Step-by-step explanation:
To find the circumference of a circle you have to use the formula:
c= 2 [tex]\pi[/tex] r
c being circumference
r being radius
If your given diameter than divide that by 2 to get radius
[In case you need it in the future]
To find area of a circle use the formula:
A = [tex]\pi[/tex] r^2
A being area
r being radius
