What is PEMDAS?PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. PEMDAS is an acronym that stands for P-Parenthesis, E-Exponents, M-Multiplication, D-Division, A-Addition, and S-Subtraction.
The given expression can be simplified as shown below.
(14 - 30)/ 2 (- 4)
Using the rule of PEMDAS, solving parenthesis first,
= (14-30) / (-8)
= (-16)/ (-8)
Solving the division,
= 2
Hence, The value of the given expression (14-30)/2(-4) when simplified is 2.

Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distance from Lanya's home to the store?
Answers
Answer:
Option A: 4 units is the correct answer.
Step-by-step explanation:
Given that:
Layana's house is located at ([tex]2\frac{2}{3}, 7\frac{1}{3}[/tex])
Store is located at ([tex]-1\frac{1}{3},7\frac{1}3}[/tex])
We can find distance between two points by using distance formula.
S = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The points can also be written as;
House (8/3, 22/3)
Store (-4/3, 22/3)
Putting values in the formula.
S = [tex]\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2[/tex]
S = [tex]\sqrt(\frac{8}{3}+\frac{4}{3}+0[/tex]
S = [tex]\sqrt{(\frac{8+4}{3})^2[/tex]
S = [tex]\sqrt{(\frac{12}{4})^2[/tex]
S = [tex]\sqrt{(4)^2[/tex]
S = 4 units
Hence,
Option A: 4 units is the correct answer.

Step-by-step explanation:
There are 14 rows of seats in a cinema.
There are 15 seats in each row.
A film was shown in the cinema on Saturday,
Each ticket for the film cost £6.50
The tickets that were sold cost a total of £1274
How many tickets were not sold?
Answers
Answer:
24 tickets were not sold
Step-by-step explanation:
Here, we want to get the number of unsold tickets
In each row, there are 15 seats
In the Cinema, there are 14 rows
The total number of seats is thus;
15 * 14 = 220 seats
If all the 220 seats were booked, the total amount of ticket sales would have been;
220 * 6.5 = £1430
But in this case, the amount generated is £1,274
Hence, the difference in these amounts will be;
1430 - 1274 = £156
To get the number of tickets unsold, we have to divide the amount here by the price per unit ticket
Mathematically, we have this as;
£156/£6.5 = 24

The price of strawberries varies directly with the weight of the strawberries purchased. Two pounds of strawberries cost $6.
What is the cost of 7 pounds of strawberries?
Answers
Answer:
$21
Step-by-step explanation:
2Lbs. = $6
(2/2) = (6/2)
1Lbs. = $3
(1*7) = (3*7)
7Lbs = $21
Since strawberries are priced on weight, you first need to find the weight of one pound. The prices need to be proportional, so whatever you do to one side of the equal sign, you need to do to the other. Divide both numbers by 2. One pound costs three dollars. Then multiply both numbers by 7. Seven pounds of strawberries cost twenty-one dollars

NEED HELP PLZ ANSWER IMMEDIATELY IM GOING TO GET IN TROUBLE A jacket usually sells for $61.00. If the jacket is 40% off, and sales tax is 8%, what is the total price of the jacket, including tax?
Answers
Answer:
$39.528
Step-by-step explanation:
61*0.6 = 36.6
36.6*1.08 = $39.528
Answer:
39.53
Step-by-step explanation:
Multiply 61 by .4. The answer is 24.4. Subtract 24.4 from 61. This is the sale price after the discount but before the sales tax. The answer to that is 36.6. Multiply 36.6 by .08, the answer is 2.928. Round to the nearest hundreths. Add this to 36.6. You're final answer is 39.53.

B) 3x4 – 8x3 = x + 2
C) 3x3 – x2 =12
D) x - x2 + 3x4
Answers
Answer:
B.
Step-by-step explanation:
A fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴-8x³=x+2].
What is a trinomial?A trinomial in elementary algebra is a polynomial made up of three terms, or monomials.An algebraic expression with three non-zero terms is called a trinomial. Trinomial expression examples: A trinomial with the variables x, y, and z is x + y + z.A trinomial in one variable, 2a² + 5a + 7, exists.So, we know that a trinomial is made up of 3 terms.
4th-degree trinomial means that it has a power of 4.And with a coefficient of 3.So, such expression is: 3x⁴ - 8x³ = x + 2
Therefore, a fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴ - 8x³ = x + 2].

t = 3 years
I = Prt
I = 18790 * 0.049 * 3

Explore the properties of angles and arcs
formed by two intersecting secants.
1. Find the difference of arc measures.
mAC - mDE
Answers
Answer:
1.) Find the difference of arc measures.
mAC - mDE = 56
2.) Multiply the angle measure by 2.
2(mABC)= 56
3.) Moving points A and C to change
the angle and arcs and make a
conjecture.
The difference of arc measures
always equal 2 times the
angle measure.
The difference of arc measures is always equal to two times the angles measured at an external point of the circle.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The dimensions are given as
m∠ABC = 28°
mAC = 80
mDE = 24
The difference of arc measure will be
mAC - mDE = 80 - 24
mAC - mDE = 56
Multiply the measure of the angle m∠ABC by 2.
2 (m∠ABC) = 2 (28°)
2 (m∠ABC) = 56°
Moving points A and C to change the angle and arcs make a conjecture.
The difference of arc measures is always equal to two times the angles measured at an external point of the circle.

Answers
A recipe yields = 8(1/2) cups.
And,
Each serving = (1/4) cups.
Therefore,
The number of servings his recipe will yield = (Total recipe yields) ÷ (Each serving) = 8(1/2) ÷ (1/4) = 8 and 1 over 2 ÷ 1 over 4 (Option D).
