Step-by-step explanation:
X/6 ≤ 30
to find the value of X we have to move the numerical to the other side
in this case the number is 1/6
X * 1/6 ≤ 30
so to balance the both side and get rid of the number on the left side we multiple with 6.
1/6*6 = 1 on the left side
30*6 = 180 on the right side
so the full equation will be
X * 1/6 * 6 ≤ 30 * 6
X * 1 ≤ 180
X ≤ 180

Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older than Jenny. How old is each now?
Answer:
Jenny's is 8 now and Sammie is 17.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
Jenny's age is x.
Sammie's age is y.
Jenny is 9 years younger than Sammie.
This means that:
[tex]x = y - 9[/tex]
Five years ago, Sammie was four times older than Jenny.
This means that:
[tex]y - 5 = 4(x - 5)[/tex]
Since [tex]x = y - 9[/tex]
[tex]y - 5 = 4(y - 9 - 5)[/tex]
[tex]y - 5 = 4(y - 14)[/tex]
[tex]y - 5 = 4y - 56[/tex]
[tex]3y = 51[/tex]
[tex]y = \frac{51}{3}[/tex]
[tex]y = 17[/tex]
[tex]x = y - 9 = 17 - 9 = 8[/tex]
Jenny's is 8 now and Sammie is 17.
Evaluate 3(c+d) if c=8 and d=-5
A. 6
B. 9
C. 39
D. -9
Answer:
C
Step-by-step explanation:
3(8+5)=39
3(13)=39
or
3(8)+3(5)=39
Answer:
b. 9
Step-by-step explanation:
if c = 8 and d = - 5
3( c + d)
= 3( 8 + (-5))
= 3 * 3
= 9
The population in City A is 3 1/2 times the population of City B. The population of City B is 1,800,000. What is the population of City A?
Answer:
The population of city A is 6,300,000.
Step-by-step explanation:
1,800,000 × 3[tex]\frac{1}{2}[/tex]
3[tex]\frac{1}{2}[/tex] is equal to 3.5
Plug in 1,800,000 × 3.5 into your calculator
= 6,300,000
A house that you are interested in has the following facts listed online: Price = $214,000 APR = 1.15% Down Payment must be 9.5% Loan time frame is 35 years What is the amount of the loan you must take out? What monthly price do you have to pay on this house? What is the total price of this house (including interest and the down payment)?
9514 1404 393
Answer:
$20,330 down$193,670 loan$560.35 monthly$255,677 total priceStep-by-step explanation:
a) The down payment is 9.5% of the price, so is ...
down = 0.095×$214,000 = $20,330
__
b) The amount of the loan is the remaining value after the down payment is made:
$214,000 -20,330 = $193,670
__
c) The monthly payment is given by the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
payment on Principal P at interest rate r for t years
A = $193,670(0.0115/12)/(1 -(1 +0.0115/12)^(-12·35)) ≈ $560.35
__
d) The total cost of the house is ...
down + (monthly payment)×(number of months)
= $20,330 + $560.35×420
= $255,677
Two similar squares are in a ratio of 3:5. If a side of the larger square is 35 inches, what is the measure of a side of the smaller square?
f(x) = -2x^2-4x+11
in the standard form
f(x) = a(x – h)^2+k
Step-by-step explanation:
f(x) = -2x^2-4x+11
y = -2(x+1)²+13
Use the vertex form, y=a(x−h)²+k, to determine the values of a, h, and k.
a= -2
h= 1
k= 13
Final answer is, f(x) = -2(x - 1)² + 13
Answer:
f(x) = - 2(x + 1)² + 13
Step-by-step explanation:
f(x) = - 2x² - 4x + 11
f(x) = a(x - h)² + k
a = - 2, b = - 4, c = 11
h = - [tex]\frac{b}{2a}[/tex]
h = - [tex]\frac{-4}{2(-2)}[/tex] = - 1
k = - 2( - 1)² - 4( - 1) + 11 = 13
f(x) = - 2(x + 1)² + 13

The value of the digit 6 in the number 47,602 is 10 times the value of the digit 6 in which number?
A. 76.201
B. 60.245
C. 53.462
D. 46,290
Answer:
Answer B
Step-by-step explanation:
In 47,602, the six is in the hundreds place.
We can divide 100/10 to get what place value it should be in. This gives us the tens place.
Now, we can see which number has a six in the tens place: Answer B, because sixty is 6 * 10.

Step-by-step explanation:
what is the value of y?
9514 1404 393
Answer:
y = 8√3
Step-by-step explanation:
In the 30°-60°-90° "special" triangle, the ratio of sides lengths is ...
1 : √3 : 2 = 8 : y : hypotenuse
In order for these ratios to be equal, we must have ...
y = 8√3
__
If you want to solve this using your trig skills, you recognize that ...
Tan = Opposite/Adjacent
tan(30°) = 8/y
y = 8/tan(30°) . . . . where tan(30°) = 1/√3
y = 8√3
You operate the cash register at a retail store. A customer's total including tax, is $14.17, and you receive $20.00 as payment. How much change should you give the customer?
Answer:
$ 20.00 - $14.17 = $5.83
Step-by-step explanation:
you have to take the amount of money given and subtract the total of the purchase , with the total including tax that makes it easier because you dont have to calculate it . so payment - total = change

What is the product of 2 and 3/6 write another expression that is equal to the product of 2 3/6
Answer:
The product of 2 and 3/6 is 1
Another expression equal to 2 x 3/6 is 4 x 1/4
Step-by-step explanation:
To find the product of 2 and 3/6, you should first simply 3/6. Find the GCM of 3 and 6. The GCM should be 3, so you divide each side by 3. Then you multiply 1/2 and 2 which is 1. To find another product of 2 x 3/6, you could just another fraction for 1/2.
Hope this helps
The another expression that is equal to the product of 2 & 3/6 is : 3 x 9/27.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is the the product of 2 and 3/6.
We can write -
2 x 3/6 = 1
We can write another expression that is equal to the product of 2 & 3/6 as -
3 x 9/27
Therefore, the another expression that is equal to the product of 2 & 3/6 is : 3 x 9/27.
