Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.
Simplify the expression:
(15 + 8d) (-5) - 24d + d
Answer:
-3 • (21d + 25)
Step-by-step explanation:
suppose a line has slope -2/3 and passes through the point (1, 8). which other point must also be on the graph
A (7, 4)
B (7, 12)
C (-5, 4)
D(-5, -12)
Answer:
A(7,4)
Step-by-step explanation:
-2/3 is the slope and the slope is the rise over the run, and we know it passes through the point (1,8).
Next, we can create a chart/table
X int-1+3=4, 4+3=7
Y int-8-2=6,6-2=4
1st point: (4,6)
2nd point: (7,4)
Hope I helped, have a nice day :)
factor the polynomial below completely.
z^2 + 9z + 20
Answer:
Step-by-step explanation:
z^2+9z+20
=z^2+(5+4)z+20
=z^2+5z+4z+20
=z(z+5)+4(z+5)
=(z+5)(z+4)

what does n)-2 mean ??
The letter “n” notates “number” and refers to any number, similar to “x.” The little carat means they the number following, in this case a 2, is an exponent. So this can really be understood as “x squared.” Most likely, this term appeared in an equation.
Ryan wants to describe the translation shown on the grid below.
On a coordinate plane, triangle X Y Z is shifted 1 unit to the left and 3 units up to form triangle X prime Y prime Z prime.
Ryan uses the following steps to describe the translation.
Step 1 Identify the pre-image and the image:
The pre-image is triangle XYZ, and the image is X prime Y prime Z prime.
Step 2
Identify the number of units that each point moves horizontally:
Each point moves one unit left.
Step 3
Identify the number of units that each point moves vertically:
Each point moves three units down.
Step 4
The translation is one unit left and three units down.

someone please help me with this math question
Answer:
x = 52
Step-by-step explanation:
An isosceles triangle is a triangle with two congruent sides, meaning two sides have the same measure. One property of an isosceles triangle is the base angles theorm. This theorem states that the angles opposite the congruent sides in an isosceles triangle are cognruent. Applying this theorem to the given triangle, one can state the following:
52 = x
Answer:
I think the answer is 52 so x=52
Solve The System
-5x-5y=0
6x+5y=12
9514 1404 393
Answer:
(x, y) = (12, -12)
Step-by-step explanation:
The two equations can be added to solve for x.
(-5x -5y) +(6x +5y) = (0) +(12)
x = 12 . . . . . . . . simplify
-5(12) -5(y) = 0 . . . substitute into the first equation
12 +y = 0 . . . . . . . divide by -5
y = -12 . . . . . . . . subtract 12
The solution is (x, y) = (12, -12).

Find the speed of the train if the the train travels 360 miles in 4 hours.
Answer:
90 mph
Step-by-step explanation:
To get miles per hour ([tex]m/h[/tex]), we just need to divide. [tex]360/4[/tex] gives us [tex]90/1[/tex], meaning the train travelled 90 miles in one hour. This is the same as going 90 mph. Hope that explained things :)

A loaf of bread costs $0.90. Each loaf has 15 slices. How much does each slice of bread cost?
Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
Answer:
0.9/15=$0.06 per slice
Also what is this 1910 when did a loaf of bread cost 90 cents????

A chair rental company charges $100 for delivery plus $3 per chair.
You have $410 to spend on chairs. How many can you rent?
Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down
103 chairs
Answer:
I think 3 chairs. (sorry, i read the equation wrong)

2x+y=5 , 3x+2y=8 solve using cross multiplication
Answer:
x=2
y=1
Step-by-step explanation:
2x+y=5
3x+2y= 8
<=> 6x+3y=15
6x+4y=16
<=> -y=-1
2x+y=5
<=> y=1
2x+1=5
<=> y=1
2x=4
<=> y=1
x=2
An object is launched from the roof of a building 192
feet above the ground. The object's height (in feet)
after t seconds is given by the function
h(t) = -1672 +64t + 192
B) How many seconds does it take the object to hit the
ground?
Answer:
Unsure, sorry
Step-by-step explanation:
Answer:
t=6
Step-by-step explanation:
h(t) = -16t^2 +64t + 192
We want h(t) =0
0 = -16t^2 +64t + 192
Factor out -16
0 = -16 (t^2 -4t -12)
Factor. What terms multiply to -12 and add to -4 -6*2 = -12 -6+2 = -4
0 = -16(t-6)(t+2)
Using the zero product property
0=t+2 0=t-6
t = -2 t=6
But t=-2 happens before the event occurs so the solution is t=6

Need help on this question asap please
Answer:
Choice C
Step-by-step explanation:
$80 to 5 hours
Divide both numbers by 5 to find the unit rate:
$16 to 1 hour, or 16 to 1
For x hours, the pay, y, is y = 16x.
Choice A is true.
Look at choice B.
When x = 5, y = 80.
This is correct because we are given that information.
The process is to multiply the hours by 16.
For x hours, y = 16x (from choice A)
For x = 7, y = 7 * 16
Choice B works.
Look at choice C.
We need a proportion. The left side is the ratio 80/5, meaning $80 for 5 hours of work. Notice that the first number in the ratio is dollars, and the second number is hours. Now we need another ratio written in the same order to set up a proportion. x dollars is to 7 hours. This is the ratio x/7. The correct proportion is
80/5 = x/7
Choice C is 80/5 = 7/x
Choice C is incorrect.
Look at choice D.
The graph shows that for 5 hours, the pay is $80, so by looking up x = 7, you can find the correct amount of pay.
Choice D works.
Answer: Choice C

Step-by-step explanation:
Answer:
-4 over 5

15/x=10/2
Find x please
Answer:
x=3
Step-by-step explanation:
15/x=10/2
Simplifying the right side
15/x = 5
Multiply each side by x
15/x *x = 5x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x

Answer:
x = 9
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal if m is parallel to n
6x+5 = 7x-4
Subtract 6x from each side
6x -6x+5 = 7x-6x-4
