iF J is between C and T, find the value of x and JT. CJ=8x+5, CT=55, and JT=4x+2
x=
JT=
Answer:
x = 4JT = 18Step-by-step explanation:
Given three points J, C and T on a line, if J is between C and T then;
CJ + JT = CT.
Given CJ=8x+5, CT=55, and JT=4x+2, substituting this parameters in the equation above will give;
[tex](8x+5)+(4x+2)= 55\\8x+4x+5+2 = 55\\12x+7 = 55\\12x = 55-7\\12x = 48\\ x = \frac{48}{12} \\x = 4[/tex]
SInce JT = 4x+2
[tex]JT = 4(4)+2\\JT = 16+2\\JT = 18[/tex]

Which statement about the point (0, 5) is true?
It is on the origin.
It is in Quadrant I.
It is on the x-axis.
It is on the y-axis.
Answer:
(0,5) is on the y-axis
Step-by-step explanation:
Since the x value is 0, it is not left or right of (0,0), thus it does not leave the y-axis. Since its y-value Is 5, it goes up 5 units from (0,0) but still it does not leave the y-axis.
Answer:
it is on the y-axis

Diego was trying to write 2^3 * 2^2 with a single exponent and wrote 2^6 explain to Diego what his mistake was and what the answer should be
Answer:
Diego's mistake is that he multiplied the exponents, instead of adding. The answer should be [tex]2^{3+2} = 2^{5}[/tex]
Step-by-step explanation:
Suppose we have a base a, and two exponents, b and c, we have that:
[tex]a^{b} \times a^{c} = a^{b+c}[/tex]
In this problem:
[tex]a = 2, b = 3, c = 2[/tex]
Diego's mistake is that he multiplied the exponents, instead of adding. The answer should be [tex]2^{3+2} = 2^{5}[/tex]

4/3 es lo que pasa cuando haces las operaciones.
3 + (5 + 7) Use the commutative property of operations to reverse the numbers in the expression. Use the associative property of operations to change the grouping after reversing the numbers in the expression. Evaluate the expression.
Answer:
commutative property:
A + B = B + A
So we have
3 + (5 + 7) = (5 + 7) + 3
Now distributive means that:
A + (B + C) = (A + B) + C
So (5 + 7) + 3 = 5 + (7 + 3)
now the equation is easier to solve, because 7 + 3 = 10
5 + (7 + 3) = 5 + 10 = 15
Answer:
Use the commutative property of operations to reverse the numbers in the expression.
✔ 3 + (7 + 5)
Use the associative property of operations to change the grouping after reversing the numbers in the expression.
✔ (3 + 7) + 5
Evaluate the expression.
✔ 15

Mason cuts a giant circular cookie into 5 equal pieces. Which statements are true about the angle measures of the pieces?
Answer:
A statement that is true about the angle measures of the pieces is that the angle measure of each piece is 72°. This is because there are 360° in a full circle, and if each piece is equal, that means that each piece is a fifth of that. Therefore, the angle measure is 360/5= 72°
If J is between H and K and HJ = 4x+9, JK = 3x+3 and KH = 33. What is the value of HJ?
Answer:
Step-by-step explanation:
Assuming KH is a straight line with K and H being the beginning and the end of the line. If J is between H and K, it means that J is a point on line HK. Therefore, we can say that
HJ + JK= KH
If HJ = 4x + 9, JK = 3x + 3 and KH = 33, it means that
4x + 9 + 3x + 3 = 33
4x + 3x = 33 - (9 + 3)
7x = 21
Dividing both sides of the equation by 7, it becomes
x = 21/7 = 3
Therefore, HJ = 4 × 3 + 9 = 21

3 + 2x ≥ -4 solutions
Answer:
x ≥ -7/2
Step-by-step explanation:
3 + 2x ≥ -4
Subtract 3 from each side
3-3 + 2x ≥ -4-3
2x ≥ -7
Divide each side by 2
2x/2 ≥ -7/2
x ≥ -7/2
Steps to solve:
3 + 2x ≥ -4
~Subtract 3 to both sides
3 - 3 + 2x ≥ -4 - 3
~Simplify
2x ≥ -7
~Divide 2 to both sides
2x/2 ≥ -7/2
~Simplify
x ≥ -3.5

a hexagon has 5 sides measured as 115 , find the sixth side
Answer:
31
Step-by-step explanation:
115 divided by 5 equals 31 and each side measures 31 so the 6th side measures 31
or
Angle sum of hexagon is 720 .
So,116*5(5 side are given)
=580
580+x=720 (x is the sixth side of hexagon)
x=720-580
=140°

Find 25% of 30.
A. 32
B. 3.25
C. 32.5
D. 325
Answer:
Huh, the answer option doesn't exist. The answer is 7.5 You can double check my answer by multiplying 7.5*4 because 25% is 1/4th of 100%.
Step-by-step explanation:
Use cross multiplication. I've heard it being called butterfly multiplication. I'll try to represent it as best as I can.
x 25
---- = --------
30 100
You multiply 30 by 25 and x by 100
x*100=30*25
Then solve for x
x*100=750
x=750/100
x=7.5

A cylindrical swimming pool has a diameter of 18 feet and a height of 4 feet. About how many liters of water are needed to fill the swimming pool 85% of its total volume? Round your answer to the nearest whole number. (1 ft³ ≈ 28.3 L) To the nearest whole number of liters.
Answer:
31 liters
Step-by-step explanation:
(9^2)4(3.14) = 1017.36
1017.36(.85) = 864.756
864.756/28.3 = 30.56 = 31 liters

Find the probability that a point in the figure chosen at random is in the
shaded kite. *Remember, the are of a kite is found by one half of diagonal
1 times diagonal 2. *
A)1/3
B)1/4
C)3/4
D)1/2
Answer:
Correct option: D) 1/2
Step-by-step explanation:
First we need to find the area of the kite and the area of the rectangle.
The diagonals of the kite are 16 and 12, as they are parallel to the sides of the rectangle.
So the area of the kite is A1 = (1/2) * 16 * 12 = 96
The area of the rectagle is the product of the sides, so A2 = 16 * 12 = 192
Now, to find the probability of a random point being inside the kite, we just need to divide the area of the kite by the area of the rectangle:
Probability = A1 / A2 = 96 / 192 = 1/2
Correct option: D)
