Answer:
x = 4k
Step-by-step explanation:
6kx = 4kx + 8
The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.
2kx = 8
Next, move the 2k to the right side of the = by dividing both sides by 2k
x = 8/2k
The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.
x = 4k

Step-by-step explanation:
If a coordinate is on the x or y axis then it is NOT in a quadrant. True or False?
Answer:
True
Step-by-step explanation:
For something to be in a quadrant, the y and x coordinate have to be greater than 0. If a coordinate is on the y-axis or x-axis either x or y coordinate will be 0. That is why it is not in a quadrant.

The scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches what is the actual distance between these streets
Answers
1 3/7 miles
2 3/8 miles
4 1/4 miles
4 3/8 miles
Answer:
4 3/8 miles
Step-by-step explanation:
We are told that: the scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches
If 1 inches = 2 1/2 miles
1 3/4 inches =
Cross Multiply
1 3/4 × 2 1/2/1
= 7/4 × 5/2
= 35/8
= 4 3/8 miles
The actual distance between these streets is 4 3/8 miles

2. Solve 8(4-x) = 10
[tex] x = 2 \frac{3}{4} [/tex]
Step-by-step explanation:
[tex]8(4 - x) = 10[/tex]
Expand :
8(4-x) = 32-8x
[tex]32 - 8x = 10[/tex]
Collect like terms and simplify
[tex] - 8x = 10 - 32 \\ - 8x = - 22[/tex]
Divide through by -8
[tex] \frac{ - 8x}{ - 8} = \frac{ - 22}{ - 8} [/tex]
Simplify
[tex]x = 2 \frac{6}{8} \\ \\ x = 2 \frac{3}{4} [/tex]

Cheryl’s recipe for homemade pudding calls for 4 1/2 cups of water and 2 cups cream. She decides to scale the recipe to use all 3 2/3 cups of cream she has in her refrigerator. How much water should she use?
A. 8 1/4 cups
B. 8 1/10 cups
C. 6 1/6 cups
D. 4 1/2 cups
Tysm!
Answer:
a 8 1/4 c
Step-by-step explanation:
I converted to decimals first. 4.5 c water to 2 c cream. wants to use 3.66 cream. 3.66/2= 1.83. she is increasing cream by 1.83%, next multiply same % to water. 4.5 cups * 1.83 = 8.235 which is closest to 8.25= 8 1/4

What is the measure in degrees of the smaller of the angles formed by the hands of a clock at 7:48?
Answer:
So the measure in degrees of the smaller angle formed by the hands of the clock at 7:48 is 24 degrees
Step-by-step explanation:
At 7:48 , we have two angles formed
One formed by the hour and the other formed by the minute hand
The angle formed by the hour hand will be;
7/12 * 360 = 210 degrees
Let’s now go for the minutes hand
mathematically;
60 minutes = 360 degrees
So 48 minutes will be ;
Recall;
there are 12 hours on a clock, so each hour will be 30 degrees
So the angle for 48 minutes will be;
48/60 * 30 = 24 degrees

3/4 (6x + 1) - 3x = 1/4 (2x - 1)
3/4 (6x + 1) - 3x = 1/4 (2x - 1) . The purpose of this question is to solve for x.
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]
Given that:
3/4 (6x + 1) - 3x = 1/4 (2x - 1)When calculating algebraic expression, we take note of integers in bracket first, then we collect the like terms in order to find the value of x.
[tex]\mathbf{\dfrac{3}{4} (6x + 1) - 3x =\dfrac{1}{4} (2x - 1) }[/tex]
Let's multiply both sides by 4 to eliminate the fraction.
[tex]\mathbf{(\dfrac{3}{4} \times 4) (6x + 1) - 3x =(\dfrac{1}{4} \times 4 ) (2x - 1) }[/tex]
[tex]\mathbf{(3) (6x + 1) - 3x =(1 ) (2x - 1) }[/tex]
Open brackets;18x + 3 - 3x = 2x - 1
By rearrangement;18x - 3x + 3 = 2x - 1
15x + 3 = 2x - 1
Collect like terms15x - 2x = - 3 - 1
13x = - 4
Divide both sides by 13[tex]\mathbf{\dfrac{13x}{13} = \dfrac{-4}{13}}[/tex]
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]

thank you very much
Answer:
x. a.
y. b
z. c.
Step-by-step explanation:
So from the middle column, we know that each row or colum must be -12 because 1 - 8 - 5. x + 1 - 12 should be = - 12, so x -11 = 12, so x = -1
For z, - 12 + 3 + z = -12, so z = -3
For y, y - 5 + z = -12, but we know z so we can plug in -3:
y - 5 - 3 = - 12
y - 8 = -12
so y must be -4

9514 1404 393
Answer:
see below
Step-by-step explanation:
When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Angle AQA' is 60 degrees.
-Triangles ABC and A'B'C' are congruent.
-Angle ABC is congruent to angle A'B'C'. (this is one of the angles of the congruent triangles)
-Segment BC is congruent to segment B'C'
-Segment AQ is congruent to segment A'Q.
i need helppp asap 7x+3=4x-9
Answer: -4
Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.
