Answer: x = 1 and y = 2
Step-by-step explanation:
Solve for y in the first equation by adding 2x to both sides
[tex]y=2x[/tex]
Plug this answer into the y for the second equation
[tex]3x+4(2x)=11[/tex]
Combine like terms and simplify
[tex]3x+8x=11\\11x=11\\x=1[/tex]
Now solve for the y value by plugging in x to any equation
[tex]y=2x\\y=2(1)\\y=2[/tex]
Sandy's dad just finished working and was paid $8000 for his work. Her dad gave her mom 5/8 of his salary to pay for household expenses. Her mom gave her brother 1/15 of the amount she received as allowances for her brother. Her brother gave Sandy 2/3 of his allowances because he owed her money. How much money did Sandy get from her brother?
a) Write an equation for this scenario
b) Solve the scenario and find out how much money Sandy got from her brother
Answer:
Sandy got (approximately) $222.22 from her brother.
Step-by-step explanation:
5/8 (8000) = 5000
1/15 (5000) = 333.33
2/3(333.33) = 222.22

Bethany makes 50 hotdogs to divide equally between 6 people. How many hotdogs does each person get?
Henry spends $50.00 on lunch, $12.00 on a cap and spends $6.00 on bananas. Hicks spend $120.00 on clothes and $15 on a cap. Henry borrowed money from Hicks to buy his items. In other words, Hicks paid for Henry. Lucky for Hicks he had a discount coupon for 10% off his lunch. Hicks bank account has a balance of $225.
A. How much will the purchase cost him
b. What would Hick’s bank balance be after all the debts were paid?
Answer:
The purchase will cost him $158.
Hick's bank balance would be $67 after all the debts were paid.
Step-by-step explanation:
10% of $50= $5.
$120.00 + $15.00 + $12.00 + $6.00 + 5.00= $158
$225 - $158 = $67

A rectangular water tank contains 1440 litres of water. If its length is 120cm and breadth is 80cm, find the height of the water level in the tank.(1 litre=1000cm cube.)
Answer:
Answer is 150cm
Step-by-step explanation:
Here
l = 120cm
B = 80cm
Rectangular tank contain 1440l of water
As as we know 1l = 1000cm^3
So 1440l = 1440000cm^3
Here,
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm

If h= n + 4, and if n = 7, what is h?
A)
3
B)
1
D)
12
What is h
Answer:
11
Step-by-step explanation:
If n=7, you would substitute n in the equation with 7.
h=7+4
h=11
Answer:
h=11
Step-by-step explanation:
h = n + 4
but n = 7
h = 7 + 4
h=11

Dylan, Alan, Bruce, and Cecil are brothers. Dylan weighs d pounds. Alan weighs 3 pounds more than twice what Dylan weighs. Bruce weighs 12
pounds less than three times what Dylan weighs. If Cecil weighs the same as the combined weight of Bruce and Alan, what is Cecil's welght in
terms of Dylan's weight (d)?
Complete the steps below to solve this problem and others like it.
Part A
Alan weighs 3 pounds more than twice what Dylan weighs. Write an explession to represent Alan's weight in terms of Dylan's weight.
Answer:
Step-by-step explanation:
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
Answer:
2d + 3
Step-by-step explanation:
Dylan’s weight is d.
Twice Dylan’s weight is 2d.
Three pounds more than twice Dylan’s weight is 2d + 3.
So, the expression for Alan’s weight in terms of Dylan’s weight is 2d + 3.

Which sentence is true?
All whole numbers are also natural numbers.
b All integers are also rational numbers.
All rational numbers are also integers.
d. All integers are also whole numbers.
Answer:
Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.
Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…
Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…
All integers belong to the rational numbers. A rational number is a number
ab,b≠0
Where a and b are both integers.
Example
The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:
41
or
82
or even
−8−2
Whereas
15=0.2
is a rational number but not an integer.
A rational number written in a decimal form can either be terminating as in:
15=0.2
Or repeating as in
56=0.83333...
All rational numbers belong to the real numbers.
If you look at a numeral line
picture05
You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number's absolute value. It is shown with the symbol
|x|
If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.
|10|=10=|−10|
