Answer:
-46
Step-by-step explanation:
2x+43=2x-3
We simplify the equation to the form, which is simple to understand
2x+43=2x-3
We move all terms containing x to the left and all other terms to the right.
+2x-2x=-3-43
We simplify left and right side of the equation.
0x=-46
0=-46
The left and right sides are not equal, therefore there is no solution. This equation is invalid.

PLSS HELP IMMEDIATELY!!!! ILL MARK BRAINIEST IF U DONT LEAVE A LINK OR GUESS!!!!
I already answer this on the other one, but here it is again.
Answer:
13 5/8 Or 13.625
Explanation:
• Let's start with 1/4. There are five days that has the amount of 1/4 of rainfall.
So we have to add all five of the 1/4 or just multiply:
1/4 x 5 = 5/4
• Now for the 3/8. There are twelve days that has that amount of rainfall.
3/8 x 12 = 36/8
· For 1/2. There are five days.
1/2 x 5 = 5/2
· For 5/8. There's five days.
5/8 x 5 = 25/8
• Lastly for 3/4. There is three days.
3/4 x 3 = 9/4
• Now we add all of the amount together: 5/4 + 36/8 + 5/2 + 25/8 + 9/4
- To add, we have to find the Least Common Denominator (LCD), which is 8.
So we have to make all of the fractions into a denominator of 8 by multiplying:
5/4 –> 10/8 (Multiply by 2)
36/8 (Stays the same, already have the denominator of 8)
5/2 –> 20/8 (Multiply by 4)
25/8 (Stays the same, already have the denominator of 8)
9/4 –> 18/8 (Multiply by 2)
• Now add:
10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8
109/8 = 13 5/8
Or as decimal form: 13.625

Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.

Answer:
9) 3.7 in
10) 12 in²
11) 18 in³
12) V=432π cm³
TSA= 216π cm²
13)V=448π ft³
TSA=240π ft²
Step-by-step explanation:
9) Since all side of the trapezium are the same the height = perpendicular line which is 3.7 in
10) 3×4 (the quadrilateral at the bottom)
11)∵ A= Cross-sectional area× height
⇒A= Area of the trapezium × 4
∴ A=[tex]\frac{1}{2} \\[/tex] (sum of the parallel sides) × 4
A=[tex]\frac{1}{2} \\[/tex] (3+6) × 4
A= 18 in²
12) V=πr²h
V=π(6)²(12)
⇒V=432 cm³
TSA=2(πr²)+2πrh
TSA=2(π(6)²)+2π(6)(12)
⇒TSA=240π cm²
13. V=πr²h
V=π(8)²(7)
V=448π ft³
TSA=2(πr²)+2πrh
TSA=2(π(8)²)+2π(8)(7)
TSA=240π ft²
9) 3.7 in
10) 12 in²
11) 18 in³
12) V=432π cm³
TSA= 216π cm²
13)V=448π ft³
TSA=240π ft²

Alica created a portrait that is 10 inches wide and 13 inches long she wants to put a frame that is 2 1/4 wide on each side
Answer:
[tex]A_f=470ft[/tex]
[tex]P_f=88ft[/tex]
Step-by-step explanation:
From the question we are told that:
Width of Portrait [tex]w=10inches[/tex]
length of Portrait [tex]l=13inches[/tex]
Frame each [tex]l_W=21/4inch each[/tex]
Generally the equation for area of portrait A is mathematically given by
[tex]A=w*l\\A=10*13\\A=130m^2[/tex]
Generally the equation for Perimeter of portrait is mathematically given by
[tex]P=2(w+l)\\P=2(10+13)\\P=46m[/tex]
Generally the equation for area of portrait with frame is mathematically given by
[tex]A=w_f*l_f[/tex]
where
w_f=width of portrait with frame
[tex]w_f=2*21/4+w\\w_f=2*21/4+10\\w_f=20.5ft[/tex]
l_f=Length of portrait with frame
[tex]l_f=2*21/4+l\\l_f=2*21/4+13\\l_f=23.5ft[/tex]
Therefore Area of picture with frame
[tex]A_f=w_f*l_f[/tex]
[tex]A_f=20.5*23.5[/tex]
[tex]A_f=470ft[/tex]
Generally the equation for Perimeter of portrait is mathematically given by
[tex]P_f=2(w_f+l_f)\\P_f=2(20.5+23.5)\\P_f=88ft[/tex]
What is the probability of drawing an even numbered card, keeping it, and then drawing another even numbered card from a stack of 24
cards numbered 1 to 247
Oct
O
С C
46
Answer: 1/4
Step-by-step explanation:
In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.
Reasoning How could you write, as a percent
without dividing?
You choose two different movies on a list at random. Out of 10 movies on the list, 6 are action movies. The first movie you choose is an action movie. What is the probability that the second movie is also an action movie? Write your answer as a fraction in simplest form.
Answer:
5/9
Step-by-step explanation:
You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.

Rori read 5 books last month. Here are the number of pages in each book that she read. (120, 106, 94, 100, 180) What is the mean absolute deviation (MAD) of the number of pages in the 5 books Rori read?
Answer:The mean absolute deviation (MAD) of the number of pages in the 5 books Rori read =24
Step-by-step explanation:
To find the the mean absolute deviation (MAD,we start firt by
Getting the mean of all values
Mean =120, 106, 94, 100, 180/5 =600/5=120
Next we subtract the mean value from each value which is called distance
120 -120 = 0
106 -120 = -14
94 -120= -26
100 -120=-20
180 -120=60
Thirldly, we find the mean of the distances ignoring the negative signs
0+14+26+20+60 / 5 = 120/5=24
what is the lcm of 32 and 14
the answer is 224 im pretty sure hope this helps

please help asap for the area. i got homework to submit in 5 minutes
Answer:
area = 228 m^2
Step-by-step explanation:
here's your solution
=> length = 20 m. , width = 12 m
=> Area of rectangle = length*width
=> Area of rectangle = 12*20
=> Area of rectangle = 240 m^2
now we need to find area of traingle
=> base = 4 m. , height = 6 m
=> area of traingle = 1/2*base*height
=> area of traingle = 1/2*4*6
=> area of traingle = 12 m^2
=> now , area of figure = 240 m^2 - 12 m^2
=> 228 m^2

Answer:
408.3%
Step-by-step explanation:
last year there were 480 students in school and this year it has become 600 find the percentage increase in the number of students
Answer:
25%Steps:
600 - 480 = 120
100(120/480) = 25
Answer:
increase in percentage = 25%
Step-by-step explanation:
here's your solution
==> Total number of students last year = 480
==> Number of students this year = 600
==> Number of increased students = 600 - 480
= 120 students
==> now , in percentage = (120/480)*100
==> percentage increase = 25%

Solve triangle PQR. Round intermediate results to 3 decimal places and final answers to 1 decimal place.
Answer:
[tex]Q = 96.4^\circ[/tex]
[tex]R = 58.4[/tex]
[tex]P =25.2[/tex]
Step-by-step explanation:
Given
See attachment for PQR
Required
Solve the triangle
From the attached triangle, all sidea of the triangle are known.
i.e.
[tex]PQ = 6\\QR=3\\PR=7[/tex]
So, we are to solve for [tex]\angle P, Q \& R[/tex]
Using cosine rule:
[tex]a^2 = b^2 + c^2 - 2bcCosA[/tex]
To solve for Q, we have:
[tex]PR^2 = PQ^2 + QR^2 - 2 * PQ * QR Cos(Q)[/tex]
[tex]7^2 = 6^2 + 3^2 - 2 * 6 * 3 * \cos(Q)[/tex]
[tex]49 = 36 + 9 - 36 * \cos(Q)[/tex]
Collect like terms
[tex]49 - 36 - 9 = - 36 * \cos(Q)[/tex]
[tex]4 = - 36 * \cos(Q)[/tex]
Divide both sides by -36
[tex]\cos(Q) = \frac{-4}{36}[/tex]
[tex]\cos(Q) = -0.1111[/tex]
Take arc cos of both sides
[tex]Q = cos^{-1}(0.1111)[/tex]
[tex]Q = 96.4^\circ[/tex]
To solve for R, we make use of sine rule;
[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]
So, we have:
[tex]\frac{PQ}{\sin R} = \frac{PR}{\sin Q}[/tex]
[tex]\frac{6}{\sin R} = \frac{7}{\sin 96.4}[/tex]
Cross multiply
[tex]\sin R * 7 = 6 * \sin 96.4[/tex]
Solve for sin R
[tex]\sin R = \frac{6 * \sin 96.4}{7}[/tex]
[tex]\sin R = \frac{6 * \0.9938}{7}[/tex]
[tex]\sin R = 0.8518[/tex]
Take arc sin of both sides
[tex]R = sin^{-1}(0.8518)[/tex]
[tex]R = 58.4[/tex]
Solving P:
[tex]P+ Q + R = 180[/tex] --- angles in a triangle
Solve for P
[tex]P =180-Q-R[/tex]
[tex]P =180-96.4-58.4[/tex]
[tex]P =25.2[/tex]
