Answer:

150

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

<1 + <2 = <3

3x+11 + 3x+19 = 7x+10

Combine like terms

6x+30 = 7x+10

Subtract 6x from each side

6x -6x+30 = 7x-6x+10

30 = x+10

Subtract 10 from each side

30-10 = x+10-10

20 =x

We need to find angle 3

<3 = 7x+10

= 7(20)+10

= 140+10

= 150

On a test, shelly got approximately 93% of the items correct. she got 76 questions right. how many questions were on the test? a

You multiply 76 by 0.93. That is 70.68 which rounds to 71. To check, (71/76) = ~93.

A/20 + 14/15 = 9/15 <br><br> Can i get some help?

KiRa [710]

Method 1:

$\dfrac{a}{20}+\dfrac{14}{15}=\dfrac{9}{15}\ \ \ \ |multiply\ both\ sides\ by\ 60\\\\60\cdot\dfrac{a}{20}+60\cdot\dfrac{14}{15}=60\cdot\dfrac{9}{15}\\\\3a+4\cdot14=4\cdot9\\\\3a+56=36\ \ \ \ |subtract\ 56\ from\ both\ sides\\\\3a=-20\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{a=-\frac{20}{3}\to a=-6\frac{2}{3}}$

Method 2.

$\dfrac{a}{20}+\dfrac{14}{15}=\dfrac{9}{15}\ \ \ \ |subtract\ \dfrac{14}{15}\ form\ both\ sides\\\\\dfrac{a}{20}=-\dfrac{5}{15}\\\\\dfrac{a}{20}=-\dfrac{1}{3}\ \ \ \ |multiply\ both\ sides\ by\ 20\\\\\boxed{a=-\dfrac{20}{3}\to a=-6\frac{2}{3}}$

5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?

vovangra [49]

First, we must find the common denominator (12) ✵

10/12-6/12 ✵ ✵ ✵ ✵

Now, why 10? ✵ ✵ ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵ • - ○

4/12 ✧ ✩ ✶ ✺ ✱

We can simplify, or reduce, this fraction: ✱ ✱

1/3 ✩ ✦ ✤

I hope it helps!
