What is ratio ?Ratios are required form comparing two or more quantities which are of same type.
a/b can be written in ratio form a:b.
According to the given question
A candy store makes a 12-lb mixture of gummy bears, jelly beans, and gobstoppers.
The mixture calls for three times as many gummy bears as jelly beans.
∴ If the mixture has 1 lb of jelly beans then it will also hence 3 lbs of gummy bears.
By going through options we can observe option B is satisfying this condition as 6 lbs of gummy bears is 3 times 2 lbs of jelly beans and the rest are gobstoppers which is 4 pounds.
For more assurance to our given choice we can check with the price of individual contents too.
Total mixture is 24 dollars and gummy bears, jelly beans and gobstoppers costs 2 dollars, 3 dollars and 1.5 dollars respectively.
∴ 6(2) + 2(3) + 4(1.5)
= 12 + 6 + 6
= 24 dollars.

Answer:
for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]
Step-by-step explanation:
For A
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]6a-3+3=7b-10+3[/tex]
[tex]6a=7b-7[/tex]

For B

The formula A=lw gives the
area A of a rectangle with
length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?
Answer:
78 ft^2
Step-by-step explanation:
A = lw
l = 13 ft
w = 6 ft
A = 13ft x 6 ft
A = 78 ft^2
Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.

Thirteen less than twice a number is fifteen. What is the equation? What is the number?
Hi there!
Let the unknown number be c.
Twice a number means we multiply that number by 2:
2c
Now, subtract 13:
2c-13
This expression is equal to 15:
2c-13=15
As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.
Now, let's solve it for c.
2c=15+13
2c=28
c=14
Hope everything is clear :-)

1) On a road map, the distance from Louisville to St. Louis is 12 cm. If the map has
a scale of 2 cm = 20 miles, what is the distance to St. Louis?
120 miles.
All you have to do to understand this problem is the relationship between the cm and mi.
In this case:
2cm =20mi.
The relationship is times 10, because 2 x 10=20
So multiply 12 by 10, and you will get 120mi.
Therefore, the answer is 120mi.
