Point M is the midpoint of segment AB

AM = MB

50 - 3x = –20 + 4x

7x = 70

x = 10


AM = 50 - 3(10)

AM = 50 - 30

AM = 20


Answer

AM = 20

Find the values of m and n<br> Need help, thank you!!!
Wewaii [24]

Answer:

m=45 degrees

n=15 degrees

Step-by-step explanation:

m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees

180 degrees in any triangle so m=180-135=45 degrees.

m+n=60 degrees so n=60-45=15 degrees

Need help with this problem:
Nitella [24]

Answer:

<em>Henson: 3x + y = 163</em>

<em>Garcia: 2x + 3y = 174</em>

<em>adult ticket price: $45</em>

<em>child ticket price: $28</em>

Step-by-step explanation:

Henson Family:

3 adults + 1 child; total $163

3x + y = 163

Garcia Family:

2 adults + 3 children; total $174

2x + 3y = 174

Now we solve the system of equations.

Solve the first equation (Henson Family) for y.

y = 163 - 3x

Substitute 163 - 3x for y in the second equation (Garcia Family).

2x + 3<em>y</em> = 174

2x + 3(<em>163 - 3x</em>) = 174

2x + 489 - 9x = 174

-7x + 489 = 174

-7x = -315

x = 45

Now substitute 45 for x in the first original equation and solve for y.

3x + y = 163

3(45) + y = 163

135 + y = 163

y = 28

adult ticket price: $45

child ticket price: $28

What is the iterative rule for the sequence: 10.5, 9, 7.5, 6, 4.5, 3, …?
goblinko [34]
Hello,

Your sequence is arithmetic.

10.5-9=1.5
9-7.5=1.5
7.5-6=1.5
6-4.5=3
4.5-3=1.5
3-1.5=1.5
1.5-1.5=0
...
f(x)=f(n-1)-1.5 is the iterative rule.

f(1)=10.5
f(2)=10.5-1.5=9
f(3)=10.5-2*1.5=7.5
f(4)=10.5-3*1.5=6
...
f(n)=10.5-1.5*(n-1) is the general form.

The dog’s leash is 60 inches long. If the dog walks back and forth with its leash pulled tight while the leash is tied to the li
labwork [276]

Answer:

150.08 inches

Step-by-step explanation:

The question simply requires that we find the length of the arc that the dog walks.

Its leash rotates through 150° and the length of the leash (radius) is 60 inches.

The length of an arc is given as:

L = α/360 * 2πR

where α = angle of arc

R =radius

Therefore:

L = 150/360 * 2 * π * 60

L = 150.08 inches

The dog walks 150.08 inches

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
Yanka [14]

Answer:

The sum is t.

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

10t+(t-10t)

Remove the parenthesis.

10t+t-10t

Simplify the number

10t-10t+t

Use Additive inverse.

t

Hence, the sum is t.
