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.
Hope this helps!

Answer:
1. linear pair
2. Substitution Property of Equality
3. Subtraction Property of Equality
4. <1 ≅ <3
Step-by-step explanation:
1. linear pair
A linear pair is a pair of angles that that are adjacent and add to 180 degrees
linear Pair Postulate states: "If two angles form a linear pair, then the angles are supplementary.
2. Substitution Property of Equality
<1 + <2 = 180 and <2+ <3 = 180
<1 + <2 = <2 + <3
3. Subtraction Property of Equality
<1 + <2 - <2= <2 - <2+ <3
<1 = <3
4. <1 ≅ <3

Each day for two workweeks (10 days total), George weighs 4 bags from that day’s production. If the average of the means is 14 oz. and the average range is 0.4 oz., what is the lower control limit for an x-bar chart for this process?
a. 13.7084 oz.
b. 13.8768 oz.
c. 14.2916 oz.
d. 12.8000 oz.
e. 13.5908 oz.
Answer:
a. 13.7084 oz.
Step-by-step explanation:
Formula for Lower Control Limit =
(LCL = x-bar - A²R-bar)
x - bar = 14 oz
A2 = 0.729
R - bar = 0.4 oz
= 14 - 0.729 × 0.4
= 14 - 0.2916
= 13.7084oz

Answer:
A: 492 km
B: 120 m
Step-by-step explanation:
Since it's a 1:x scale, just multiply it.
120 x 4.1 = 492
Then add the unit.
Same thing for B.
4 x 30 = 120.

For the points A(-3, 2), B(-3, 7), and C(2, 7), find the equation of the line
through B perpendicular to line AC.
Answer:
The equation of the line perpendicular to AC and passing through point B is y = -x + 4
Step-by-step explanation:
We start by finding the slope and equation of line AC
The equation of a straight line can be given as;
y = mx + c
where m is the slope and c is the y-intercept
Mathematically, the slope is given as;
m = (y2-y1)/(x2-x1)
m = (7-2)/(2-(-3)) = 5/5 = 1
So the equation becomes ;
y = x + c
We only need the slope since we are trying to get another line perpendicular to this
If two lines are perpendicular, then the product of the slopes of both lines is equal to -1
This means that m1 * m2 = -1
So this means that the slope of the perpendicular line is -1/1 = -1
Thus, the equation of the line we are finding would be;
y = -x + c
since it passes through line B, we can make a substitution of the coordinates of point B
That would be;
7 = -(-3) + c
7 = 3 + c
c = 7-3
c = 4
So the equation of that line is;
y = -x + 4 or simply y = 4-x

#30 Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected. Let x represent the number of tickets sold at the door.
In terms of x. how many tickets were sold in advance?
Answer:
170 tickets were sold in advance
Step-by-step explanation:
Let x represent the = number of tickets sold at the door.
Let y represent the = number of tickets sold in advance
Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected.
Hence, we have two equations
x + y = 400 tickets
$3 × x + $2 × y = $1,030
x + y = 400.... Equation 1
x = 400 - y
3x + 2y = 1030........ Equation 2
Substitute 400 - y for x in Equation 2
3(400 - y) + 2y = 1030
1200 - 3y + 2y = 1030
Collect like terms
-y = 1030 -1200
-y = -170
y = 170
Since y represent the number of tickets sold in advance, therefore, 170 tickets were sold in advance.
A taxi charges $2.50 for each ride plus $1.25 per mile traveled.
If the total charge for one ride was $8.75, how many miles
were traveled?
Answer:
5 miles
Step-by-step explanation:
We have to figure out how many times $1.25 was charged. First, we have to do 2.50 + 1.25 = 3.75 + 1.25 = 5 + 1.25 = 6.25 + 1.25 = 7.5 + 1.25 = 8.75
We charged $1.25 5 times, so this means that it was 5 miles.
Answer:
5 miles
Explanation:
this is because if you subtract 2.50 from 8.75 then you will be left with 6.25. after you do this then you divide 6.25 by 1.25 and this will give you 5 miles.
4 movie tickets cost $48 what is the cost per ticket

what is the solution to the equasion 1/2x + 3= 2/3x + 1
Answer:
12
Step-by-step explanation:
1/2x+2=2/3x
2= 2/3x-1/2x
2=4/6x-3/6x
2=1/6x
multiply both sides by 6
x=12
Answer: x = 12
Step-by-step explanation:
1/2x + 3= 2/3x + 1
= 1/2x + 3 - 3 = 2/3x +1 -3
Simplify
= 1/2x = 2/3x -2
= -1/6x = -2
multiply both sides by -6
(-1/6x)(-6) = (-2)(-6)
x = 12

solve equation for x -16= 3x + 11
Answer:
13.5
Step-by-step explanation:
Step 1:
x - 16 = 3x + 11 Equation
Step 2:
- 16 = 2x + 11 Subtract x on both sides
Step 3:
- 27 = 2x Subtract 11 on both sides
Step 4:
x = - 27 ÷ 2
Answer:
x = 13.5
Hope This Helps :)
Answer:
[tex]x = -\frac{27}{2}[/tex]
Step-by-step explanation:
Combine like terms: x - 3x = 16 + 11Simplify: -2x = 27Divide each side by -2 to cancel out the -2 next to x. It should now look like this: x = -27/2I hope this helps!
