Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.
Mary-Ann has $28.
(2 1/3)x = 28
7/3 x = 28
Multiply both sides by 3/7.
x = 28 * 3/7
x = 12
Lola has $12.

4. A food delivery service charges a $100 membership fee to join, and also charges $5 for each delivery. Find the linear equation that models the cost based on number of deliveries. At the total cost of $200, how many deliveries will have been made?
Answer:
200-100=5(x)
Step-by-step explanation:
If the total cost is 200 dollars and we spent 100 on the fee, we have 100 dolars for deliveries.
If each delivery is 5 dollars, then the amount of money spent on deliveries is x(unknown) dollars then we have 200 - 100 = 5 x <--unknown
total money^ ^fee ^each deliv

A rectangular tank has length 4m, width 12m and height 3.5..i. If the tank is filled with water 2/3 of its capacity ,calculate the volume of the water in the tank.
Answer:
The volume of the water in the tank is 112 m³
Step-by-step explanation:
The volume of the rectangular prism V = L × W × H, where
L is its lengthW is its widthH is its height∵ A rectangular tank has a length of 4 m, a width of 12 m, and
a height of 3.5 m
∴ L = 4 m
∴ W = 12 m
∴ H = 3.5 m
∵ V = L × W × H
∴ The volume of the tank = 4 × 12 × 3.5
∴ The volume of the tank = 168 m³
∵ The tank is filled with water [tex]\frac{2}{3}[/tex] of its capacity
→ That means the volume of the water is [tex]\frac{2}{3}[/tex] the volume of the tank
∵ The volume of the water = [tex]\frac{2}{3}[/tex] the volume of the tank
∴ The volume of the water = [tex]\frac{2}{3}[/tex] × 168
∴ The volume of the water = 112 m³
∴ The volume of the water in the tank is 112 m³

Evaluate the expression |2x – 5| for x = –3 and for x = 3.
A)
11, 1
B)
3, 13
C)
13, 3
D)
1, 11
Answer:
Option A: 11,1 is the correct answer.
Step-by-step explanation:
The absolute value is used in the given expressions.
The absolute value represents the values of a number or variable irrespective of its sign. This means that |x| = x and |-x| = 0
Given expression is:
[tex]|2x-5|[/tex]
Putting x=3
[tex]|2(-3)-5| \\= |-6-5|\\= |-11|\\=11[/tex]
Putting x=-3
[tex]|2(3)-5| \\= |6-5|\\= |1|\\=1[/tex]
Hence,
Option A: 11,1 is the correct answer.
Reduce the Fraction: a(x-2y)/b(2y-x)
Answer:
[tex]\displaystyle-\frac{a}{b}[/tex]
Step-by-step explanation:
We have:
[tex]\displaystyle{\frac{a(x-2y)}{b(2y-x)}[/tex]
In the denominator, we can factor out a negative 1. This yields:
[tex]=\displaystyle\frac{a(x-2y)}{-b(x-2y)}[/tex]
We can now cancel out the factor. Hence:
[tex]\displaystyle=-\frac{a}{b}[/tex]

3 divided by 1/? = 18
Answer: ? = 6
Step-by-step explanation:
3 divided by 1/x = 18
3x= 18
x = 6
Answer:
3 divided by 1 equals 3
How :
We can write 3 divided by 1 as a ratio, fraction, or equation. Let's try writing this statement in all these ways
3:1
3/1
3÷1
The easiest way for me to solve this question is as a fraction so let's solve it like that. If the denominator is a 1, we immediately know that the answer is the numerator and that you don't need the denominator. so we can take away the 1 from 3/1 and that is how our answer is 3!
Hope this Helps!!! :)
Let me know in the comments if the answer was perfect or if I should change anything!!! :)
0.3d-1/3 1/3=.84:7/15
Answer:
[tex]d=\frac{147}{6.3}[/tex]
Step-by-step explanation:
The right side is a ratio [tex]0.84:\frac{7}{15}[/tex] a ratio can be written as a fraction [tex]\frac{0.84}{\frac{7}{15} }[/tex] this means [tex]0.84[/tex] divide by [tex]\frac{7}{15}[/tex] which is the same as [tex]0.84*\frac{15}{7}=\frac{12.6}{7}[/tex] On the left, change the mixed fraction [tex]3\frac{1}{3}[/tex] to the improper fraction [tex]\frac{10}{3}[/tex] Then divide [tex]0.3d-1[/tex] by [tex]\frac{10}{3}[/tex] which is same as [tex](0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}[/tex] So the equation is now [tex]\frac{3(0.3d-1)}{10}=\frac{12.6}{7}[/tex] Now multiply both sides by 10 and 7:[tex](10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}[/tex]Answer:
d=147/6.3
Step-by-step explanation:
d = 147 / 6.3
