Answer:
-1/2x-2
Step-by-step explanation:
Distribute the negative sign from the right side to make the equation positive
1/4x - 7 + (-1)(3/4x) + (-1)(-5)
(basically multiplying -1 to 3/4x and -5 to eliminate it)
1/4x - 7 + -3/4x+ 5
Make the equation similar
(1/4x + -3/4x) + (-7 + 5)
combine like terms
1/4x + -3/4x = -2/4x --> Simplifies to -1/2x
Do the other integers
-7 + 5 = -2
Put it together
-1/2x-2

Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole. Relative to ground level, what is the elevation of the hole after placing the shrub in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
15/6
Step-by-step explanation:
(20/9) ft of the hole is elevated after the shrub was placed.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.
In 15 minutes, the depth of hole digged is (2/3) feet.
In 1 minute, the depth of hole digged is {(2/3)/15} feet.
In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.
The hole filled after placing the shrub will be -
(5/6) x (8/3)
5/6 x 8/3
5/3 x 4/3
20/9
Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.

A: n + 6 = 78
B: 3n + 6 = 78
C: n - 6 = 78
D: 3n - 6 = 78
Firefighters need to cross from the roof of a 25-feet-tall building to the roof of a 35-feet-tall building by using a ladder. The buildings are 20 feet apart. What minimum length does the ladder need to be in order to span the two buildings?
which expression means “6 more than the quotient of a number and 5”
x/5+6 => expression means “6 more than the quotient of a number and 5”.
Option B is correct.
Here,
The expression that means "6 more than the quotient of a number and 5" can be written as:
(x / 5) + 6
In this expression, "x" represents the unknown number.
Let's break down the expression and explain it step by step:
(x / 5):
This part of the expression represents the quotient of "x" and 5.
It means that we divide "x" by 5.
(x / 5) + 6:
his means we take the quotient obtained in step 1 and add 6 to it.
It represents "6 more than the quotient of a number and 5."
Hence, x/5+6 => expression means “6 more than the quotient of a number and 5”.
Option B is correct.

Douglas went to Charlies General Store to get gas. He paid $52.20 for 20 gallons of gas. How much would he have paid if he got 25 gallons instead
Answer:
65.25
Step-by-step explanation:
52.20 is the total for 20 gallons of gas
we divide 52.20 by 20 to find out the price per gallon.
52.20/20= 2.61 per gallon
for 25 gallons --> 2.61 x 25 = 65.25

Answer:
D - 320
Step-by-step explanation:
You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!
pia is planting flowers. The number of tulips she plants is 4 more than half the number of daisies
The expression that represents the number of tulips Pia planted is option A. x/2 + 4.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
Number of daisies planted is represented by x.
Number of tulips planted is 4 more than half the number of daisies.
Half the number of daisies is x/2.
4 more than half the number of daisies is x/2 + 4.
Hence the number of tulips planted is given by the expression x/2 + 4.

Answer:
4 * 2y + 4 * 1
4(2y + 1)
Distributive property
Step-by-step explanation:
8y + 4
We can factor out a 4 out of both as both are divisible by 4
8y / 4 = 2y
4 / 4 = 1
So 8y + 4 is the same as saying 4 * 2y + 4 * 1
This can be written as 4(2y + 1) which is written using the distributive property

Answer:
Solution

=−9
x=3
x=−9
x=3x=−9
Step-by-step explanation:
Boom
Answer:
x=-9 and 3
Step-by-step explanation:
FOIL method
x^2+6x-27=0
Find the common numbers that multiply to 27 that will also equal 6.
(27x6) or (9x3)
the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.
then FOIL them
(x+9)(x-3)
FIRST: x*x=x^2
OUTSIDE: x*-3=-3x
INNER: 9*x=9x
LAST: +9*-3=-27
x^2(-3x9x)-27
x^2+6x-27
now that the equation matches you solve for x.
(x+9)=0 x=-9
(x-3)=0 x=3

Answer:
Problem 3: Just 33 draw 4 boxes of 11 and one with 11
Problem 4: 30
Problem 5: Naomi
Step-by-step explanation:
For problem three since you are multiplying the same equation by 4 its basically (2+9)+3(2+9) so you can just cancel out the 2+9 from both and you are left with 3(2+9) which is just 33
For problem 4 100-(12x4)=52 and 10+(3x4) = 22 and when you subtract the two (52-22) you get 30
For problem 5 you get 18 with your equation and so since Carlos' equation gets 9 and Miranda gets 24 and Will gets 35 the only one left is Naomi which also gets 18 just like you.
