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]

please help
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
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]

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.

What is the slope of 12x + 3y =7
Answer: y = -4x + 7/3 so the slope is -4
Step-by-step explanation:
First, we need to put the linear equation into the slope-intercept form: y = mx + b
We do this by subtracting 12x from both sides, so the equation now looks like 3y = -12x + 7. Now we divide both sides by 3 to get y alone, which gives us y = -4x + 7/3
m is always the slope, so the slope of this line is -4 or -4/1.
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.

George is helping the manager of the local produce market expand her business by distributing flyers
around the neighborhood. He gets paid $20 a day as well as $0.05 for every flyer he distributes.
George would like to earn at least $65 each day. Which of the following represents this situation,
where x is the number of flyers distributed.
a. 20 + 0.05x ≤ 65 c. 20 + 0.05x ≥ 65 c. 20 + 0.05x ≥ 65
b. 20 + 5x ≤ 65 d. 20 + 5x ≥ 65 d. 20 + 5x ≥ 65
Answer:
20 + 0.05x ≥ 65
Step-by-step explanation:
20 is by itself since thats what he earns extra per day.
Since he earns 0.05 per flyer, that means we are going to need a variable since we don't know how many flyers he passes. Let x be equal to that.
Since he wants to make at LEAST 65 we are going to use the greater than or equal to symbol since he doesn't want to make less than that.
20 + 0.05x ≥ 65
Best of Luck!
20 + 0.05x ≥ 65

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.

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
