When the two angles are next to each other on a straight line, they will add up to 180 degrees.

So, we can add up the expressions and set them equal to 180 degrees.

16x+3 + 12x+9 = 180

Combine like terms:

28x = 168

x= 6

Now we know what x is, all we have to do is sub in to the original expressions to get the value of the angles.

16(6) + 3 = 99
12(6) + 9 = 81

The left angle is 99 degrees, and the right is 81 degrees. You can test this again by adding it up and making sure they add to 180.

Hope this helps!

Answer:

A

Step-by-step explanation:

the standard form of a quadratic equation is

ax² + bx + c = 0 : a ≠ 0

obtain (5 + x)(5 - x) = 7 in this form by expanding the factors

25 - x ² = 7 ( subtract 7 from both sides )

18 - x² = 0 ( multiply through by - 1 )

x² - 18 = 0 ← in standard form

with a = 1, b= 0 and c = - 18 → A

Max used a base ten blocks to solve the division problem 9.15 divided by 3.
Angelina_Jolie [31]

Answer:

D 3 ones, 0 tenths, 5 hundredths

Step-by-step explanation:

9.15 divided by 3.

915/3 = 305

Then, moving the decimal point two units to the left, we have 3.05.

The last number before the decimal point is called ones, which means that we have 3 ones.

The first number after the decimal point is called tenths, which means that we have 0 tenths.

The second number after the decimal point is called hundredths, which means that we have 5 hundredths.

The correct answer is given by option D.
