For every $5 Luis saves, Olivia saves $7.
After a week, Luis saves $42 less than Olivia.
To Find :
If there favorite candy cost $2.50 per pack, how many packs of candy can each of them buy.
Solution :
Ratio of money saved by Olivia and Luis is 7/5 .
Let, money save by Olivia is x.
So, money saved by Luis is x - 42 .
[tex]\dfrac{7}{5}=\dfrac{x}{x-42}\\\\7x - 294 = 5x\\\\x =\$ 147[/tex]
Money saved by Luis, $105 .
Number of pack Olivia can buy is, = 147/2.5 = 58.8 = 58 packets.
Number of pack Luis can buy is, = 105/2.5 = 42 packets.
Therefore, Olivia and Luis can buy 58 and 42 packets respectively.

Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²

How many groups of 3/4 are in each of the following quantities? 11/4, 6 1/2
There are complete 3 groups of 3/4 in 11/4.
There are complete 8 groups of 3/4 in 6 1/2.
To find the number of groups of 3/4 in 11/4, we divide it by 3/4.
[tex]\frac{\left(\frac{11}{4}\right)}{\left(\frac{3}{4}\right)}=3.67[/tex]
So there are complete 3 groups of 3/4 in 11/4.
To find the number of groups of 3/4 in 6 1/2, we divide it by 3/4.
[tex]\frac{\left(6\frac{1}{2}\right)}{\left(\frac{3}{4}\right)}=\frac{\left(\frac{13}{2}\right)}{\left(\frac{3}{4}\right)}=8.67[/tex]
So there are complete 8 groups of 3/4 in 6 1/2.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The number of small boxes in the right side of the equation = 10 boxes of 1
So , the value of A = 10
The number of small boxes in left side of the equation = 4 boxes of 1
The number of x in the equation = 3x
So , the equation is
3x + 4 = 10 be equation (1)
On simplifying the equation , we get
Subtracting 4 on both sides of the equation , we get
3x = 6
Divide by 3 on both sides of the equation , we get
x = 6/3
x = 2
Hence , the value of the equation is x = 2

If the weight of package is multiplied by 2/7 the result is 8 pounds find the weight of the package
Answer:
28 pounds
Step-by-step explanation:
From this, you already know that 2/7 of x is equal to 8 pounds (x being the actual weight of the package). the equation would be 2/7(x)=8 to simplify this, you divide both sides by 2/7. x=8/2/7. this is the same as x=8*7/2 which is x=56/2. so your finale answer is 28 because 56/2 is 28!
10(X+1) = 2x -7 solve for X:
Answer:
x = -17/8
Step-by-step explanation:
10(x+1) = 2x - 7
=> 10x + 10 = 2x - 7
=> 10x - 2x = -10 - 7
=> 8x = -17
=> x = -17/8
