Answer:

39 touchdowns and 13 fieldgoals

Step-by-step explanation:

Let t= touchdowns

f = fieldgoals

They scored 35 times

t+f = 35

Touchdown is 7 pts and fieldgoal is 3 pt

7t+3f = 193

Multiply the first equation by-7

-7t -7f =-245

Add this to the second equation

-7t -7f =-245

7t+3f = 193

----------------------

-4f =-52

Divide by -4

-4f/-4 = -52/-4

f = 13

Now we can find t

t+f = 35

t+13 = 52

Subtract 13 from each side

t+13-13 =52-13

t =39

A man standing on a lighthouse at a height of 124 feet sights two boats directly in front of him. One is at an angle of depressi

Ksivusya [100]

Answer:

$125\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ABC find the length side BC

we know that

$tan(62\°)=\frac{124}{BC}$

$BC=\frac{124}{tan(62\°)}$

step 2

In the right triangle ABD find the length side BD

we know that

$tan(33\°)=\frac{124}{BD}$

$BD=\frac{124}{tan(33\°)}$

step 3

we know that

The distance between the two boats is the length side CD

$CD=BD-BC$

substitute the values

$CD=\frac{124}{tan(33\°)}-\frac{124}{tan(62\°)}=125\ ft$

What is the difference of the two expressions?

valkas [14]

<em>Answer is x + 12</em>

<em />

<h2>Explanation:</h2>

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:

First expression:

$2x+9$

Second expression:

$x-3$

So the operation we need to perform is:

$2x+9-(x-3)$

Recall some rules:

$(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-$

Hence:

$2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}$
