Answer:
x=4
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
Distribute
1.5x +6 -3 = 4.5x -9
Combine like terms
1.5x +3 = 4.5x -9
Subtract 1.5x from each side
1.5x -1.5x +3 = 4.5x -1.5x -9
3 = 3x-9
Add 9 to each side
3+9 = 3x-9+9
12 = 3x
Divide each side by 3
12/3 =3x/3
4=x
Answer:
B. 4
Step-by-step explanation:
Remember the acronym: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction).
P: The expressions in the parentheses are not solvable as they are.
E: There are no exponents.
M: On the left, multiply 1.5 by x, giving you 1.5x, and by 4, giving you 6. We now have 1.5x + 6 -3 on the left. On the right, do the same. Multiply 4.5 by x, giving you 4.5x, and then multiply 4.5 by -2, giving you -9. Our expression is now 1.5x + 6 - 3 = 4.5x - 9.
D: There is no division in the problem.
A: There is no addition in the problem.
S: Subtract the 3 from the 6 on the left:. We now have 1.5x + 3 = 4.5x - 9.
Now that were all simplified, lets solve. Subract 1.5x from both sides so that only one side has x, so it can be solved. We now have 3 = 3x - 9.
Add 9 to both sides, to simplify even further. We now have 12 = 3x.
For the final step, we need to isolate x. To do this, we need to get rid of the coefficient. We know that 3 and x are being multiplied, so we can just divide to undo it. Keep in mind that we need keep both sides equal, so we divide both sides. By what? By 3. Now, we have our final answer:
x = 4

14. Calculate A bird
weighing 15 g eats 10 times
its weight in food in a week.
How much food does the
bird eat in a day?
Answer:
21.429 grams per day
Step-by-step explanation:
15g times 10 =150g
150g/7 =21.429g per day
Final answer:
A bird that eats 10 times its weight in food per week, with a weight of 15 g, consumes approximately 21.43 g of food per day.
Explanation:
If a bird weighing 15 g eats 10 times its weight in food in a week, we first calculate the total amount of food the bird eats in a week and then divide that by 7 to find the daily intake.
First, we calculate the weekly food consumption:
The bird's weight = 15 g
Total weekly food intake = 15 g × 10 = 150 g
Daily food intake = Total weekly intake ÷ 7
Daily food intake = 150 g ÷ 7 ≈ 21.43 g
Therefore, the bird eats approximately 21.43 grams of food per day.

What is the volume of the prism?
ft3
1
12 ft
6 ft
8 ft
V=lwh
V=8×12×6=576 ft³
Answer: V=576 ft³
The volume of the prism is calculated by multiplying the length, width, and height, resulting in 576 cubic feet.
To calculate the volume of the prism, we have to use the formula for the volume of a rectangular prism, which is length times width times height. Given the dimensions of the prism as 12 feet in length, 6 feet in width, and 8 feet in height, the volume is calculated as follows:
Multiply the length by the width: 12 ft times 6 ft = 72 ft².Multiply the result by the height: 72 ft² times 8 ft = 576 ft³.Therefore, the volume of the prism is 576 cubic feet (ft³).

Write an equation in slope-intercept form that goes through the points (-3, -4) and (3,4).
Answer:
Y = 4/3x + 0
Step-by-step explanation:
(-3,-4) and (3,4) can be plugged in to rise over run.
y 4 -(-4) = 8
x 3 - (-3) = 6
8/6 = 4/3
Plug into slope intercept form
4 = 4/3(3) + b
4 = 12/3 +b
4 = 4 +b
Subtract from both sides
0 = b
Y = 4/3x + 0
The equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]
What is Slope of the line?The slope of a line gives the measure of its steepness and direction.
What is the Slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Given,
Slope of the line passing through the points (-3,-4) and (3,4)
Slope of the line m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}=\frac{4+4}{3+3}=\frac{8}{6}[/tex]
Therefore slope of the line is [tex]\frac{8}{6}[/tex]
Find the y intercept using the slope and the point (-3,-4)
y=mx + b
-4 = [tex]\frac{8}{6}[/tex]×-3 + b
-4 =-4+b
b=-4+4 =0
Then,
The equation in slope intercept form is
y = mx + b
y = [tex]\frac{8}{6}[/tex]x + 0
[tex]y=\frac{8}{6}x[/tex]
Hence, the equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]

WILL GIVE BRAINLIEST ANSWER TO WHOEVER ANSWERS FIRST AND CORRECTLY EXPLAIN HOW YOU ARE CORRECT
Answer:
D
Step-by-step explanation:
Since this is right triangle, we can use the Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs, and c is the hypotenuse.
14 and 16 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.
14^2+16^2=x^2
Evaluate the exponents
196+256=x^2
Add
452=x^2
To get this is simplest radical form, find the greatest square root that divides evenly into 452
4 is the greatest square root. 4 times 113 equal 452
So, we have
[tex]\sqrt{4}\sqrt{113}[/tex]
Take the square root of 4
2[tex]\sqrt{113}[/tex]
So, choice D is correct.

Missing part of the question
- 10 in, by 12 in. by 24 in.
- 12 in. by 15 in. by 18-in.
- 10 in. by 16 in. by 20 in.
- 12 in. by 12 in. by 20 in.
Answer:
The possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Step-by-step explanation:
Given
Volume of the container = 2,880 cubic inches
Required
Possible dimensions of the container
To solve this question, the following assumption has to be made;
It'll be assumed that the container is a rectangular
To calculate the volume of a rectangular figure, we simply multiply the dimensions of the figure,
This implies that; we'll test each of the given options.
Which ever gives 2,880 is the right answer.
- 10 in, by 12 in. by 24 in.
[tex]Volume = 10 in * 12 in * 24 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
- 12 in. by 15 in. by 18-in.
[tex]Volume = 12 in * 15 in * 18 in[/tex]
[tex]Volume = 3,240[/tex] cubic inches
- 10 in. by 16 in. by 20 in.
[tex]Volume = 10 in * 16 in * 20 in[/tex]
[tex]Volume = 3,200[/tex] cubic inches
- 12 in. by 12 in. by 20 in.
[tex]Volume = 12 in * 12 in * 20 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
From the calculation above, only option A and D gives 2,880;
Hence, the possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Given a volume of 2,880 cubic inches, one possible set of dimensions for a shipping container could be length = 24 inches, width = 15 inches, and height = 8 inches.
The volume of a rectangular container can be calculated by multiplying its length, width, and height. Given the volume of 2,880 cubic inches, we are looking for three numbers (dimensions) that, when multiplied together, equal 2,880.
One possible set of dimensions could be length = 24 inches, width = 15 inches, and height = 8 inches. Multiplying these dimensions together: 24 inches × 15 inches × 8 inches = 2,880 cubic inches, which matches the given volume of the container.
