When x= ([tex]10\frac{1}{3}[/tex]) the value of y is 93.
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
when x= 2/3, y=6.
Using constant proportionality
y = kx
k= y/x
k = 6 / (2/3)
k = 6 x 3/2
k = 9
Now, k= y/x
9 = y/ ([tex]10\frac{1}{3}[/tex])
9 = y / (31/ 3)
y = 9 x 31/3
y = 93
Hence, the value of y is 93.

Insert the parenthesis to make the equality right:630÷7÷2⋅9⋅25=125
Answer:
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
Step-by-step explanation:
630 ÷ 7 ÷ 2 ⋅ 9 ⋅ 25 = 125
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
90 ÷ 18 ⋅ 25 = 125
5 ⋅ 25 = 125
125 = 125
blueberries cost $4.00 per pound.A how many pounds can you buy for $1.00? so i took half of 4 which is 2 and i said it was 2 pounds and i dont know if its right
Answer: 1 /4 of a pound
Step-by-step explanation:
Since 1 pound = 4.00$, 1.00$ would equal 1/4 of a pound.
How did I solve this? I divided 4$ by 4 and got 1 then divided 1 pound by 4 and got 0.25 or 1/4
2 would not be right because you would be paying for 2 pounds which is 8 dollars, not 1.

Answer:
(x + 5)(x + 4)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
x² + 9x + 20
Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)
The factors are + 5 and + 4, since
5 × 4 = + 20 and 5 + 4 = + 9 , thus
x² + 9x + 20 = (x + 5)(x + 4) ← in factored form

Denise earns $30 an hour. She works 40 hours per week. Denise would like to purchase a computer that costs $2000. Create and solve an inequality in order to determine the least amount of hours she must work in order to be able to purchase the computer?
Answer:
67hours hoursStep-by-step explanation:
Given
she works $30 for 1 hour
in 40 hours she will earn 40*30= $1200
this means that a week she earns $1200
let the number of weeks she needs to work be x
40x*(30)<=2000
1200x<=2000
x<=2000/1200
x<=1.66
the number of hours in a week is 40
40*1.66=66.66
67hours
hence she must work for at least 67hours

Solve for x in the following equation:
kx = m + nx
Answer:
x=[tex]\frac{m}{k-n}[/tex]
Step-by-step explanation:
First you subtract nx from both side getting kx-nx=m.
Then you factor out x getting x(k-n)=m
and now you divide both sides from (k-n) and you will get the answer.

What is the answer for this expression
Answer:
x=-7
Step-by-step explanation:
1. Distribute the 7 into the parenthesis: -7-2x=7x+56
2. Combine like terms by doing the opposite operation to the numbers: -7=9x+56 (added 2x to 7x)
3. Subtract 56 to each side of the equation: -63=9x
4. To isolate the variable "x," divide each side by 9: x=-7

15(t+2)+9t=6 Please help!
Answer:
t = -1
Step-by-step explanation:
15(t+2)+9t=6
15t + 30 + 9t = 6
combine like terms
24t +30 = 6
subtract 30 both sides
24t = -24
t = -1
22-5(6v-1) = -63
22- 30v + 5 = -63
27 -30v = -63
subtract both sides by 27
-30v = -90
divide it by -30
v = 3
Answer:
-1
Step-by-step explanation:
15(t+2)+9t=6
15t+30+9t=6
15t+9t=6-30
24t/24=-24/24
t=-1
If the pattern indicated below continued, what would be the total number of cubes in the 8th stage of the pattern?
1, 1+4=5, 1+4+9=14
Answer:
The number of cubes in the 8th stage of the pattern is 204
Step-by-step explanation:
Here, we want to calculate simply the 8th term of the pattern
T1 = 1
T2 = 1 + 4 = 1 + 2^2 = 5
T3 = T2 + 3^3 = 5 + 9 = 14
T4 = T3 + 4^2 = 14 + 16 = 30
T5 = T4 + 5^2 = 30 + 25 = 55
T6 = T5 + 6^2 = 55 + 36 = 91
T7 = T6 + 7^2 = 91 + 49 = 140
T8 = T7 + 8^2 = 140 + 64 = 204
