Answer:
4x+3=6+x
x=1
Step-by-step explanation:
4x+3=6+x
3x+3=6
3x=3
x=1
Answer:
number is 1
Step-by-step explanation:
lets say the number is x. So, 4x+3=x+6 we can then subtract 3 from both sides and get 4x=x+3 then we can subtract x from both sides. So we get 3x=3. We divide both by 3 and get 1
An artist sold 10 paintings. Her first two sold for $50 and $350. She sold three at a gallery show for $250, $400 and $1,200. She sold her oil paintings on line for $410, $400 and $375. Family members bought two, one for $200 and another for $280. What is the IQR of the selling price of her paintings?
Answer:
250-400
Step-by-step explanation:
Answer:
150Step-by-step explanation:
There are 10 numbers representing the selling prices of paintings.
List the numbers in the ascending order:
50, 200, 250, 280, 350, 375, 400, 400, 410, 1200Median of the lower half is:
50, 200, 250, 280, 350 ⇒ Q1 = 250Median of the upper half is:
375, 400, 400, 410, 1200 ⇒ Q3 = 400The IQR is the difference between the upper and lower medians:
IQR = Q3 - Q1 = 400 - 250 = 150Which value of x makes the equation 1.25(4x − 10) = 7.5 true?

Give that T = 37v/6v-5.4m a. Make V the subject of relation b. If T = 4.5 and M =7x10(7),calculate the value of v , leaving your answer in standard form
Answer:
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
[tex]v = -1.701*10^8[/tex]
Step-by-step explanation:
Given
[tex]T = \frac{37v}{6v-5.4m}[/tex]
Solving (a): Make v the subject
[tex]T = \frac{37v}{6v-5.4m}[/tex]
Cross Multiply:
[tex](6v-5.4m)T = 37v[/tex]
Open bracket
[tex]6vT - 5.4mT = 37v[/tex]
Collect Like terms
[tex]6vT - 37v= 5.4mT[/tex]
Factorize:
[tex](6T - 37)v= 5.4mT[/tex]
Make v the subject
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
Solving (b):
[tex]T = 4.5[/tex]
[tex]m = 7 * 10^7[/tex]
So, the expression becomes:
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
[tex]v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}[/tex]
[tex]v = \frac{170.1*10^7}{27 - 37}[/tex]
[tex]v = \frac{170.1*10^7}{-10}[/tex]
[tex]v = -17.01*10^7[/tex]
[tex]v = -1.701*10*10^7[/tex]
[tex]v = -1.701*10^8[/tex]

HELP SIMPLE SEVENTH GRADE MATH PROBLEM. GIVING BRAINLIEST.
Answer:
D (6)
Step-by-step explanation:
FIRST METHOD
1. Use vector analogy (If you learnt)
Consider WS as a vector
x component of WS is 5
y component of WS is 3
2. Plug in numbers (Pythagorean Theorem)
[tex]\sqrt{5^{2}+3^{2}}[/tex] ≈ 5.83
Nearest integer is 6
SECOND METHOD
1. Distance between two points formula
[tex]d (length) = \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}[/tex]
W = (x1,y1) S = (x2,y2)
W = (-2,-1) S = (3,2)
2. Plug in numbers
[tex]d (length) = \sqrt{(-2-3)^{2}+(-1-2)^{2}}[/tex]
3. d ≈ 5.83

PLS HELP ME ASAP! The height and width of a rectangular prism are 26 yards and 24 yards respectively. Find the length of the
rectangular prism whose volume is 18,720 cubic yards.
Answer:
The length is 30 cubic yards.
Step-by-step explanation:
To find volume you use equation V=LxWxH
Since we already know the height, width, and volume we can input them into the equation.
18,720=L x 24 x 26
As you can see, the length is still unknown.
To figure it out though, you can multiply the height and width of the prism,
24 x 26 = 624
And then divide the volume, 18,720 by it.
18,720/624 = 30
Thus, your length is 30 cubic yards.
Mary took a math test and she got four questions incorrect and 21 correct. What percent did answer correctly?
Answer:
84%
Step-by-step explanation:
21 correct + 4 wrong = 25 questions in total
[tex]\frac{21}{25}[/tex] x 4 = [tex]\frac{84}{100}[/tex]
[tex]\frac{84}{100}[/tex] = 0.84
0.84 = 84%

Use the information to solve the triangle. Round your answers to two decimal places. Hint: draw a sketch first to determine if you should use Law of Sines or Cosines.
B=100°, a=15, b=23
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15

The circumference of a circle is 147 feet.
Find the area of the circle, in terms of pi.
Answer:
Step-by-step explanation:
C = 147 ft. The relevant formula is C = 2(pi)r, and here C = 147 ft = 2(pi)r.
The relevant area formula is A = (pi)r^2. If we solve the above formula for r we get
147 ft
r = ------------ and so r^2 (needed to calculate the area) is
2pi
147^2 ft^2
r^2 = ------------------
4(pi)
147^2 ft^2
and so the area is A = ---------------- = 7203/pi
3 pi
C C^2
Alternative method: C = 2pi*r so r = -------------- and r^2 = -------------
2 pi 4pi^2
C^2 C^2
then the area of the circle is A = pi(r^2) or pi*-------------- = ---------------
4pi^2 4pi
(147 ft)^2
and in this case the area of the circle is A = --------------
4 pi
or A = 1720 ft^2

find the area of the semicircle (1/2 circle with a diameter of 10)
Answer:
39.25 unit²
Step-by-step explanation:
Radius of circle = diameter/2 = 10/2 = 5

Find the volume of the cone-
Answer:
12.6ft³
Step-by-step explanation:
Hey There!
So the first thing we need to do is find the formula for volume of a cone
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
r = radius
h = hypotenuse
Now all we have to do is plug in the hypotenuse and the radius
[tex]V=\pi 2^{2} \frac{3}{3}[/tex]
2²=4
[tex]\frac{3}{3} =1[/tex]
4xπ=12.5663706144
And now we just round to the nearest tenth
so we can conclude that the volume of the cone is 12.6ft³
A quartic polynomial P(x) has rational coefficients. If 2 − i and-√5 are roots of P(x) = 0, what are the other 2 roots?
Answer:
2 + i and + √5
Step-by-step explanation:
Since P(x) is a quartic equation, it has 4 roots.
Since 2 - i and -√5 are two of its roots, then its conjugate pairs of 2 + i and + √5 are its other two roots.
So, its other two roots are 2 + i and + √5
