<em>Hi!</em>

<em></em>

<em>These can be set up as systems of equations.</em>

<em> </em>

<em>Let b = the number of birds, and let d = the number of dogs.</em>

<em> </em>

<em>b + d = 21</em>

<em> </em>

<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>

<em> </em>

<em>You can solve this using either elimination or substitution.</em>

<em></em>

<em>Consider marking brainliest.</em>

How many variable terms are in the expression 3x to the third power Y plus 5X to the second power plus Y +9
andrew-mc [135]

Well, variables are stuff like x and y because they can represent a number. They are variable in an equation. so if you have (3x^3)+(5X^2)+Y+9 then your variables are x X and Y (im assuming the capital X is there and not a typo) if that was a typo and meant to be lowercase, then its just a 2 variable with the x and y

Answer ASAP please, Will give brainliest.
nikdorinn [45]

Answer:

see below

Step-by-step explanation:

The measure of a minor arc is the same as the angle that forms it.

1. Since ∠GBJ = 90°, the answer is 90°.

2. ∠HBI = 180° - 151° = 29° so the answer is 29°.

3. ∠HBJ = 180° so the answer is 180°.

4. The reflex angle ∠GBI = 90 + 151 = 241° so the answer is 241°/

5. Since ∠GBJ = 90°, the reflex angle ∠GBJ = 360 - 90 = 270° so the answer is 270°.

6. ∠GBH = 180 - 90 = 90° so the reflex angle ∠GBH = 360 - 90 = 270° so the answer is 270°.
