Answer:
5(8-4)
Step-by-step explanation:
You need to do the subtraction first, so put it in parenthesis because otherwise subtraction comes after multiplication if you follow PEMDAS, then put a five outside to multiply it by the difference of 8 and 4.
Answer: 5 x (4-8) or 5(4-8)
Step-by-step explanation:
First, put 4-8 in brackets, because you need to do it first and without brackets you would do the multiplication first (because of BEDMAS). Then, you would multiply your subtraction by 5.
Hope this helps :)

Step-by-step explanation:
To find the total cost we need to know whats fixed, and what's variable (changing)
Fixed: $14 handbag
Variable: $0.50 / earring
Set up your polynomial, rule of thumb, all variables get multiplied by x
Total cost = x($0.50/earring) + $14 handbag
Substitute 0,5,10, and 15 for x and see which one matches the answer choices

Describe and correct the error a student made when graphing the linear equation y = - 6.
Answer:
The error is in computing the y intercept. It should be at (0, -6) not (0, 6)
Step-by-step explanation:
The equation of the line is
[tex]-\frac{3}{4} x - 6[/tex]
y intercept is at point x = 0
When x = 0,
[tex]y = -\frac{3}{4} x - 6\\\\y = 0 - 6 \\\\y = -6[/tex]
So y intercept is at point (0, -6)
If we plot a second point 3 units down and 4 units right we should get the point 0 + 4, -6 - 3) = (4, -9)
Plugging this into the original correct equation satisfies the equation
[tex]y = -\frac{3}{4} x - 6\\\\y = -\frac{3}{4} (4) - 6 \\\\y = -3 -6 = -9 \\\\[/tex]
So we can see that the line does pass through (4, -9)

Answer:
[tex]\displaystyle {y^4}[/tex]
Step-by-step explanation:
The GCF of a set of numbers is the biggest divider that will divide all the numbers without leaving a remainder
As an example, the GCF of 4, 8 and 20 is 4, for 3, 4 and 5 it is 1 since there is no common factor
[tex]\textrm {We have the three numbers as }[/tex] [tex]y^4, y^5 \;and\; y^{10}[/tex]
Which of these numbers will divide into each of these without leaving a remainder?
[tex]\mathrm{The \:exponent\:rule}:\quad \dfrac{x^a}{x^b}=x^{a-b}[/tex]
This means the smallest exponent value [tex]y^4[/tex] will be the GCF because
[tex]\dfrac{y^4}{y^4} = 1\\\\\dfrac{y^5}{y^4} = y^{5-4}} = y^1\\\\\dfrac{y^10}{y^4} = y^{10-4}} = y^6\\\\\\[/tex]
So the general rule for finding the GCF of [tex]y^a, y^b \;and\; y^c is\\\\\mathrm {\;Choose\; the\; one \;with \;the \;lowest \;exponent \;value \;among \;exponents\; a, \;b \;and\; c}[/tex]

A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?
A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.
How to solveTo solve this problem, we can use the following equation:
total weight / number of bags = weight of each bag
In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:
1.5 pounds / 6 bags = 0.25 pounds per bag
Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

A ÷ r and A ÷ r2.
a. 3.5, 1.8 c. 2.7, 1.8
b. 2.3, 3 d. 4.7, 3.1
Answer:
b
Step-by-step explanation:
r = 1.5
Area/A = πr²
= π(1.5)²
= 7.07
A ÷ r = 7.07 ÷ 1.5
= 4.7
A ÷ r² = 7.07 ÷ 1.5²

A rectangle has a length of 8 and width of 12. A scale copy was made with a width of 24. What is the area of the new rectangle?
Answer:
192 feet^2
Step-by-step explanation:
Length X Width = area
Answer:
The area of the new rectangle is 384 square units.
Step-by-step explanation:
For the original rectangle, the length is 8, and the width is 12. For the scale copy, the width is 24 (12 × 2), so the length will be 16 (8 × 2). Multiplying 24 by 16, we obtain 384 as the area of the new rectangle.

Find the slope of the line that has a y intercept of 4 and passes through the point (-3, 1)
Answer: m = 1 (m is slope)
Step-by-step explanation:
1. y-int is coordinate, so it is (0,4)
2. with (0,4), we can now use (-3,1):
4 - 1 = 3 and with the x, it is 0 + 3 = 3
So, it is 3/3 = 1, so the slope is 1
Answer:
Line L1 : Passes thro' (3,3)
y-intercept = 4 ===> (0,4)
Slope = (4 - 3)/(0 - 3) = 1/-3
Slope of L1 = -1/3.

The approximate weights of the two animals are 5.12 x 102 lbs. and 6.8 x 102 lbs. Find the total weight of the two animals. Write the final answer in scientific notation with the correct number of significant digits. Can you please help me and stop deleting my question :(
these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb
Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.
