Geometry HELP!! MO bisects

Mathematics

Since this is an angle bisector LMO is congruent to NMO

7x - 27 = 2x + 33
Subtract 2x
5x - 27 = 33
Add 27
5x = 60
Divide by 5
x = 12

Since it is asking for LMN plug in x to LMO and NMO equations

LMO:
7(12) - 27 = 57

NMO:
2(12) + 33 = 57

LMN:
57° + 57° = 114

So angle LMN is 114°

Find the slope of the line that passes through the given points (7, 3) and (13, 8)

k0ka [10]

Answer:

The slope is 5/8.

Step-by-step explanation:

Use the slope formula:

m = y2 - y1 / x2 - x1

Plug in the numbers from the ordered pairs:

m = 8 - 3 / 13 - 7

m = 5/8

9/10

SIZIF [17.4K]

Answer: 90%

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 9/10 as a percent, we need to find a fraction

equivalent to 9/10 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have $\frac{9}{10} = \frac{n}{100}$ .

Now, we can use cross-products to find the missing value.

So we have (9)(100) which is 900 <em>is equal</em> to (10)(n) or 10n.

So we have 900 = 10n.

Next, dividing both sides of the equation by 10, we have <em>90 = n</em>.

So, 9/10 is equal to 90/100 or 90%.

Donna takes classes at both Westside community college and pinewood community college. at westside , class fees are $98 per cred

Alex777 [14]

Answer:

Expression for the combined total dollar amount she paid for her class fees is (2185 - 17 w)

Step-by-step explanation:

Let Donna is taking w credit hours at Westside.

Total combined credit hours at two schools = 19 hours

So, the number of credit hours at Pinewood = 19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours = w x Fees per hour

= w ( $98) = $(98w)

⇒The fees Donna pays at Westside community college = $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 -w) hours = (19 -w) x Fees per hour

= (19 -w) ( $115) = $(2185 - 115 w)

⇒The fees Donna pays at Pinewood community college =$(2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w) + $(2185 - 115 w)

= $(2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $(2185 - 17 w)
