Please help me I need help with my test review I can’t figure out m<1 and m<2

aksik [14]

Answer:

m1=12 and m2=168

Step-by-step explanation:

$m1 + m2 = 180 \: (straight \: angle) \\ then \\ x - 12 + 7x = 180 \\ 8x - 12 = 180 \\ 8x = 180 + 12 = 192 \\ x = 192\div 8 \\ x = 24\\ hence \\ m1 = 24 - 12 = 12 \\ m2 = 7 \times 24 = 168.$

Find the sum of the series and show your process for finding each term leading to the final sum.

Harrizon [31]

Answer:

$\sum_{k=3}^5(-2k+5)=-9$

Step-by-step explanation:

The given series is:

$\sum_{k=3}^5(-2k+5)$

The series is not very lengthy so we can write the expanded form;

$\sum_{k=3}^5(-2k+5)=(-2(3)+5)+(-2(4)+5)+(-2(5)+5)$

This implies that;

$\sum_{k=3}^5(-2k+5)=-1+-3+-5$

$\sum_{k=3}^5(-2k+5)=-9$

How do you use an exponent to represent a number such as 16?

saw5 [17]

It would be
${4}^{2}$
Because 4 times 4 is 16, the 2 is the exponent.

Does anyone know the answer?

azamat

Answer:

1=163 degrees

2=×=10 degrees

3=×=3

Step-by-step explanation:

54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees

54x+9x+1-10=180

63x-9=180

63×=180+9

63×=189

63×÷63×=189÷63×

X=3

Angle in bold print is (54x+1)

54×3=162

162+1=163 degrees

No.2 Find x

7x+35+x+65 =180

7x+x+35×65=180

8x+100=180

8x=180-100

8x=80

8x÷8x=80÷8

X=10 degrees

No.3 Find x

54x+1+9x-10=180

54x+9x+1-10=180

63x-9=180

63x=180+9

63x=189

63x÷63x=189÷63

X=3
