18x-3=12
18x=15
so,x=5/6
15(x -20)-21= -3(x+1)+6
Answer:
x = 18
Step-by-step explanation:
Solve for x:
15 (x - 20) - 21 = 6 - 3 (x + 1)
Hint: | Distribute 15 over x - 20.
15 (x - 20) = 15 x - 300:
15 x - 300 - 21 = 6 - 3 (x + 1)
Hint: | Group like terms in 15 x - 300 - 21.
Grouping like terms, 15 x - 300 - 21 = 15 x + (-300 - 21):
15 x + (-300 - 21) = 6 - 3 (x + 1)
Hint: | Evaluate -300 - 21.
-300 - 21 = -321:
15 x + -321 = 6 - 3 (x + 1)
Hint: | Distribute -3 over x + 1.
-3 (x + 1) = -3 x - 3:
15 x - 321 = -3 x - 3 + 6
Hint: | Group like terms in -3 x - 3 + 6.
Grouping like terms, -3 x - 3 + 6 = (6 - 3) - 3 x:
15 x - 321 = (6 - 3) - 3 x
Hint: | Evaluate 6 - 3.
6 - 3 = 3:
15 x - 321 = 3 - 3 x
Hint: | Move terms with x to the left hand side.
Add 3 x to both sides:
15 x + 3 x - 321 = (3 x - 3 x) + 3
Hint: | Look for the difference of two identical terms.
3 x - 3 x = 0:
15 x + 3 x - 321 = 3
Hint: | Group like terms in 15 x + 3 x - 321.
Grouping like terms, 15 x + 3 x - 321 = (15 x + 3 x) - 321:
(15 x + 3 x) - 321 = 3
Hint: | Add like terms in 15 x + 3 x.
15 x + 3 x = 18 x:
18 x - 321 = 3
Hint: | Isolate terms with x to the left hand side.
Add 321 to both sides:
18 x + (321 - 321) = 321 + 3
Hint: | Look for the difference of two identical terms.
321 - 321 = 0:
18 x = 3 + 321
Hint: | Evaluate 3 + 321.
3 + 321 = 324:
18 x = 324
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 18 x = 324 by 18:
(18 x)/18 = 324/18
Hint: | Any nonzero number divided by itself is one.
18/18 = 1:
x = 324/18
Hint: | Reduce 324/18 to lowest terms. Start by finding the GCD of 324 and 18.
The gcd of 324 and 18 is 18, so 324/18 = (18×18)/(18×1) = 18/18×18 = 18:
Answer: x = 18

maya drive 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
8 hours
Step-by-step explanation:110 miles ................. 5 hours
176 miles ..................x hours
x = 176×5/110 = 880/110 = 8 hours
Answer:
maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
We use the rule of three
110 miles -------------> 5 hours
176 miles ------------> ???
So (176 miles × 5 hours) /110 miles
We simplify by 《miles》 because it is in the numerator and the denominator
SO (176×5 hours )/110
= 880 hours / 110
= 8 hours
So she drives 176 miles in 8 hours.

●-2
●0
●2
●4
Answer:
0 is the answer
Step-by-step explanation:
The position of point P is at 0 on number line.
What is Number line?
Number line is a straight line with numbers placed at equal intervals.
Given that;
Point C is located at -4.
Point D is located at 6.
Now,
Distance between points -4 and 6 is,
6 - (-4) = 6 + 4 = 10
Since, Point P be located so that the directed line segment from C to D will be partitioned in a 2 : 3.
Let partitions are 2x and 3x.
Then,
2x + 3x = 10
5x = 10
x = 2
So, The partitions between point C and D is,
2x = 2 × 2 = 4
3x = 3 × 2 = 6
So, The ratio become = 4 : 6
Thus, Position of point P from C = - 4 + 4 = 0
Position of point P from D = 6 - 6 = 0
So, The position of point P is at 0 on number line.

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3
Answer:
126 in³
Step-by-step explanation:
Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:
Volume of cylinder = πr²h
Where,
r = radius = ½ of d = ½*4 = 2 in
h = height = 10 in
Take π as 3.14
Plug in the values into the formula
Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

Answer:
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]
Step-by-step explanation:
To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.
[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]
LCM of the denominators,
2 | 25 11 100 24
2 | 25 11 50 12
5 | 25 11 25 6
5 | 5 11 5 6
1 11 1 6
LCM = 2×2×5×5×6×11 = 6600
[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]
[tex]=\frac{792}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]
[tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]
[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]
[tex]=\frac{594}{6600}[/tex]
[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]
[tex]=\frac{275\pi }{6600}[/tex]
[tex]=\frac{864}{6600}[/tex]
Now we can arrange these fractions in the order of greatest to least.
[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]

Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign of the larger number. In complete sentences explain what Hannah got wrong. What should the correct answer be?
Answer:
The sum is 1
Step-by-step explanation:
When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.
Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.

What is the value of p in the linear equation 24p +12 - 18p = 10 + 2p - 6 ? −4 −2 2 4
Answer:
SO we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
p = -2
The value of p is -2.
The correct option is (B)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
24p +12 - 18p = 10 + 2p - 6
Now, solving for p
6p + 12= 2p + 4
6p - 2p = 4 -12
4p = -8
p= -8/4
p= -2
Hence, the value of p is -2.

36=4/9d what does d equal
Answer:
d = 81
Step-by-step explanation:
Solve for d:
36 = (4 d)/9
Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.
36 = (4 d)/9 is equivalent to (4 d)/9 = 36:
(4 d)/9 = 36
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (4 d)/9 = 36 by 9/4:
(9×4 d)/(4×9) = 9/4×36
Hint: | Express 9/4×4/9 as a single fraction.
9/4×4/9 = (9×4)/(4×9):
(9×4)/(4×9) d = 9/4×36
Hint: | Express 9/4×36 as a single fraction.
9/4×36 = (9×36)/4:
(9×4 d)/(4×9) = (9×36)/4
Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).
(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:
d = (9×36)/4
Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.
36/4 = (4×9)/4 = 9:
d = 9×9
Hint: | Multiply 9 and 9 together.
9×9 = 81:
Answer: d = 81

Step-by-step explanation:
If we assume that the combination of green and pink means, 1 green and 1 pink, then we can say the following:
P = 1 / 25 + 1 / 25
P = 2 / 25
This is because the squares where green and pink intersect only occurs twice.
