Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
Answer:
Step-by-step explanation:
4x + 15 > 23
4x > 8
x > 2

The equation 320=x+7.50(36) represents the cost of ordering potted plants at a second store.
What does the x represent in this situation?
Answer:
I would say it's the amount of potted plants.
Step-by-step explanation:
x is the independent variable and y is the dependent variable. Y counts on x, so total cost counts on the amount of potted plants.

the diagonals of a rhombus are in the ratio 3 :4 if the longer diagonals is of 12 cm then find the area of rhombus.
Answer:
Area= 54 cm^2
Step-by-step explanation:
Recall that a rhombus is given by the product of its two diagonals (d1 and d2) divided by 2.
Area = d1 * d2 / 2
So in our case, the longer diagonal is 12 cm long, and the shortest one should be in the ratio 3:4, therefore:
3 /4 = d2 / d1
3 / 4 = d2 / 12
d2 = 3 * 12 /4
d2 = 3 * 3
d2 = 9 cm
Then we can now calculate the Area of the rhombus as;
Area = d1 * d2 / 2 = 12 * 9 / 2 = 54 cm^2

3. What is the slope of a line perpendicular to the line y =-2/3
x+12
Answer:
Slope of line (i) = 1.5
Step-by-step explanation:
Line (i) is perpendicular to;Line (ii) whose equation is y = [tex]-\frac{2}{3} x + 12[/tex]The slope of line (ii) = [tex]-\frac{2}{3}[/tex]
* Mathematics rule: The product of slopes of two perpendicular lines = -1
∴ The slope of line (i) = -1 ÷ [tex]-\frac{2}{3}[/tex] = 3/2 = 1.5

For how many different pairs of positive integers (a,b) with greatest common factor 1, and with a>b, does ab=30!
Answer:
4 pairs
Step-by-step explanation:
Given
ab = 30
Where
a > b
Required
Determine number of pairs (a,b)
To do this, we simply test values for a and b that satisfy the required condition.
First,
Take a = 30
Substitute 30 for a in ab = 30
30 * b = 30
b = 30/30
b = 1
The pair is (30,1)
Take a = 15
Substitute 15 for a in ab = 30
15 * b = 30
b = 30/15
b = 2
The pair is (15,2)
Take a = 10
Substitute 10 for a in ab = 30
10 * b = 30
b = 30/10
b = 3
The pair is (10,3)
Take a = 6
Substitute 6 for a in ab = 30
6 * b = 30
b = 30/6
b = 5
The pair is (6,5)
There exist no other pair that satisfy the given condition.
Counting the above pairs, there are just 4 pairs.

Detormine graphically (using technology) to the nearest year, after how many years will the two accounts have the same balance.
Answer:
3 years i think
Step-by-step explanation:
Find the sum.
(n+8)+(n−12)
=
n=2
Reorder terms:
(8+n)+(n-12)=0
Remover first parentheses :
8+n+(n-12)=0
Reorder (again):
8-12+n+n=0
Simplify:
-4+2n=0
Add 4 to both sides:
2n=4
Divide and you’re done!
n=2

Statement 2)
A)Addition property
B) Definition of midpoint
C) Definition of equality
D) Segment addition postulate
Reason 6)
A) Subtraction property
B) Transitive property
C) Property of equality
D) Definition of congruence
Answer:
Addition Property of Equality If AB = CD then AB + BC = BC +CD
Subtraction Property of Equality If AB + BC = BC + CD then AB = CD
Multiplication Property of Equality If m∢A = 90 then 2(m∢A) = 180
Division Property of Equaliity If 2(m∢B) = 180 then m∢B = 90
Substitution Property If m∢A + m∢B =180 and m∢B then m∢A + 90 =180
Distributive Property AB + AB = 2AB
Reflexive Property m∢B = m∢B
Symmetric Property If AB + BC = AC then AC = AB + BC
Transitive Property If AB ≅ BC and BC ≅ CD then AB ≅ CD
Segment Addition Postulate If C is between B and D, then BC + CD = BD
Angle Addition Postulate If D is a point in the interior of ∢ABC then m∢ABD + m∢DBC = m∢ABC
Linear Pair Postulate If two angles form a linear pair, then they are supplementary
Definition of Right Angle If ∢B is a right angle then m∢B = 90
Definition of Midpoint If P is the midpoint of segment AB then AP =PB
Definition of Segment Bisector If k intersects segment AB at M the Midpoint then k bisects segment AB
Definition of Perpendicular Lines If two lines are ⊥ they form right angles
Definition of Congruent Segments If AB = CD then segment AB ≅ segment CD
Definition of Congruent Angles If ∡A ≅∡ B then m∡A=m∡B
Definition of Angle Bisector If ray AB bisects ∡CAD then∡ CAB ≅ ∡ BAD
Definition of Complementary Angles If ∡ Z and ∡Y are complementary m∡Z +m∡Y =90

Answer:
1.80 + 3.72 (0.25 x b) = 13.02
Step-by-step explanation:
First, combine the "one-time" costs (the medium pendant and the medium chain)
1.80 + 3.72 = 5.52
Now, multiply the cost of the beads by the amount of beads you want
0.25 x 30 = 7.50
Now combine both costs to get the total cost
5.52 + 7.50 = 13.02
It would cost Tamara $13.02 to make a medium length necklace

what's the question??
Oranges were on sale for $0.45 per pound. Leo bought 12.6 pounds. Which expression shows how to determine the total cost of the oranges?
12.6 times 0.45
12.6 minus 0.45
12.6 + 0.45
12.6 divided by 0.45
Answer:
12.6 times 0.45
price: .45
quantity: 12.6
cost = price x quantity
Answer:
12.6 x 0.45
Since you know how much Is each pound and you want to buy 12.6 pounds. all you have to do is multiply them both.

6th grade question please help show work
Answer:
A. -6
Step-by-step explanation:
Simplify the given expression.
(6x^4 - 3x^2) + (x^2 - 5)(qx^2 + 5) =
= 6x^4 - 3x^2 + qx^4 + 5x^2 - 5qx^2 - 25
= 6x^4 + qx^4 + 2x^2 - 5qx^2 - 25
= (6 + q)x^4 + (2 - 5q)x^2 - 25
Set ti equal to the given solution.
(6 + q)x^4 + (2 - 5q)x^2 - 25 = 32x^2 - 25
The solution has no 4th degree term, so
6 + q = 0
q = -6
As a check, the solution's x^2 term is 32x^2, so
(2 - 5q)x^2 = 32x^2
2 - 5q = 32
-5q = 30
q = -6
Once again, we get q = -6.
Answer: A. -6
