Mathematics
1 answer:
damaskus [11]3 years ago
3 0

Answer:

∠B = 17°

Step-by-step explanation:

Vertical angles are congruent, thus

5x + 7 = x + 15 ( subtract x from both sides )

4x + 7 = 15 ( subtract 7 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Hence

∠B = 5x + 7 = (5 × 2) + 7 = 10 + 2 = 17°

densk [106]
It is 1595. Put it on excel so you can better have an overview how it is done. You need 5 columns, column A-E. On column A, put 1 to 5 in rows 1 to 5. On column C, put the answers: 2, 7, 26, 101 and 400. On column D, put number 3 in all 5 rows. Back on column B, insert =sum(C1-A1) on row 1 and copy till row 5. On column E, insert =sum(B1+C1*D1) on row 1 and copy till row 5 and you will get 1595 at the end.

Find the slope of the graph and the unit rate
Lilit [14]

Answer:

<u>For the 1st graph</u>

Slope     = \frac{6}{10}

Unit rate =0.6 mi/h

               

<u>For the 2nd graph</u>

Slope     = \frac{9}{4}

Unit rate =2.25 mi/h=


Step-by-step explanation:

<u>For the 1st graph</u>

Slope is given as \frac{Rise}{Run}

Rise = (6-0) = 6

Run = (10-0) = 10

Therefore,

Slope     = \frac{6}{10}

Unit rate = \frac{6}{10}

               =0.6 mi/h

<u>For the 2nd graph</u>

Rise = (9-0) = 6

Run = (4-0) = 10

Therefore,

Slope     = \frac{9}{4}

Unit rate = \frac{9}{4}

               =2.25 mi/h
