Answer:

5/2

Step-by-step explanation:

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

Answer:

12

Step-by-step explanation:

divide 48 by 4 and the answer should be 12, that is the cost per ticket.

Answer:

Each ticket cost $12

Step-by-step explanation:

So we can say:

4x = $48

we can divide each side by 4 and get:

x = $12

Hope that helps!!

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

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

Answer:

its either b or c but I'm pretty sure its b

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.

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:

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.

120 m

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:

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.

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
