One store has carrots on sale for $1.1 for 3 pounds, while another store has carrots on sale for $0.78 for two pounds. Which store has the better deal?
Maria want to buy a pencil for everyone in her class. It costs $0.78 for 3 pencils. How much Maria have to spend if she bought a pencil for each of her 24 classmate?
Answer:
1) The store selling for 1.1 per 3 lbs
2) $6.24
Step-by-step explanation:
1)
1.1/3 = 0.37
0.78/2 = 0.39
0.37 is cheaper so it's a better deal
2)
[tex]\frac{0.78}{3} =\frac{x}{24} \\\\3x=18.72\\x=6.24[/tex]
Answer:
1.10 for 3 is the better deal. It will cost $6.24 for the pencils.
Step-by-step explanation:
Do two separate problems but find how much it is for 1 carrot. So the first is:$1.10 divided by 3 carrots = .366 or 37 cents per carrot.
The second one is: .78 divided by 2 carrots = .39 cents per carrot.
If you break 24 students into groups of 3, that would be 8 groups. 24 divided by 3 = 8.
8 sets of 3 pencils is .78 x 8 = $6.24
Which set of ordered pairs is not a direct variation?
{(2,6), (8,12), (14,18)}
{(6,6), (12,12), (18,18)}
{(3,6), (6,12), (9,18)}
{(2,6), (4,12), (6,18)}
Answer:
The first option is not a direct variation
Step-by-step explanation:
When we talk of a direct variation, as one value increases, the other value increases too
Or as one value decreases, the other value decreases
A direct variation is of the form;
y = kx
k = y/x
where k is the coefficient of variation that must be a constant value all through the set of values
The values we are comparing here are the x and y values
So
let us take a look at the options;
The first option is not a direct variation
For the first option, the rate of increase is not constant;
2/6 = 1/3 , 8/12 = 2/3 , 14/18 = 7/9
for the second;
the ratio is 1 to 1
for the third;
3/6 = 1/2 ; 6/12 = 1/2; 9/18 = 1/2
for the fourth;
2/6 = 1/3, 4/12 = 1/3 , 6/18 = 1/3

Tom's property has a shape of a parallelogram with the dimensions of l= x +75 and w= x + 45. If the perimeter is 300 feet, what is the value of x
Answer:
15 feets
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets

Answer:
55 bricks
Step-by-step explanation:
First find the area of one brick by multiplying 10x6x4, which is 240 cm^3. Then divide that from 13,200 which gives you 55 bricks.
Answer:
55 bricks
Step-by-step explanation:
First, we know they used 13,200 cm^3 of concrete. cm^3 is a volume, so in order to find how many bricks can be made, we must find the volume of each brick. Multiply the dimensions of each brick. 10*6*4=240cm^3. Now, divide 13,200cm^3/240cm^3=55 bricks
given g(x)=-x-3, solve for x when g (x) =6
Answer:
x = - 9
Step-by-step explanation:
Given g(x) = - x - 3 and g(x) = 6, then equate, that is
- x - 3 = 6 ( add 3 to both sides )
- x = 9 ( multiply both sides by - 1 )
x = - 9
Answer:
-9
Step-by-step explanation:
g(-6) = -6 - 3
g(-6) = -9

The answer is 3
Open the brackets:2(3x - 7)=6x -14
6x - 14 +18 =22
Take all the numbers to the other side
6x =22+14-18
6x =18
Divide by 6 kn both sides
x=3

The equation 230 = d – 240 describes the distance in miles between Pensacola and Tampa. If d is the distance between the two cities, how many miles apart are Pensacola and Tampa?
Answer:
hi
Step-by-step explanation:
x+1/x-1-x-1/x+1=7/12
Given:
The equation is:
[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]
To find:
The value of x.
Solution:
Formulae used:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
[tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex](a-b)(a+b)=a^2-b^2[/tex]
We have,
[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]
Taking LCM, we get
[tex]\dfrac{(x+1)^2-(x^2-1)^2}{(x-1)(x+1)}=\dfrac{7}{12}[/tex]
[tex]\dfrac{x^2+2x+1-(x^2-2x+1)}{x^2-1^2}=\dfrac{7}{12}[/tex]
On cross multiplication, we get
[tex]12(x^2+2x+1-x^2+2x-1)=7(x^2-1)[/tex]
[tex]12(4x)=7x^2-7[/tex]
[tex]48x=7x^2-7[/tex]
[tex]0=7x^2-48x-7[/tex]
Splitting the middle term, we get
[tex]7x^2-49x+x-7=0[/tex]
[tex]7x(x-7)+1(x-7)=0[/tex]
[tex](7x+1)(x-7)=0[/tex]
[tex]x=-\dfrac{1}{7},7[/tex]
Therefore, the values of x are [tex]-\dfrac{1}{7}[/tex] and [tex]7[/tex].
Trechelle is buying a sports coat that has a regular price of $90. This coat is on sale with a 20% discount. She knows she needs to pay 8\%8% sales tax on the discounted price. Trechelle thinks to herself 20\%-8\%=12\%20%−8%=12%. She now believes this means she is really only getting a 12% discount, and 12% of $90 is $10.80. She works out the sports coat will cost her $79.20$. Is Trechelle’s reasoning correct or will the sports coat actually cost a different amount?
Answer:
Trechelle's reasoning is incorrect.
