Answer:
21:9
Step-by-step explanation:
when you divide 21 and 9 by 3, you get 7 and 3 respectively
I would say 2.5 because if the constant of proportionality was 2 the 4 and 2 also meet. Also at the end the 10 and 4 meet and 10 divided by 4 is 2.5
Answer:
Your answer is -37.
Step-by-step explanation:
g(-6)=5(-6)-7
g(-6)=-30-7
g(-6)=-37

Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.
__
2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra
Answer: The answer is 3ab + 2a + 3b.
Step-by-step explanation:
So we are given this equation:
2ab - ab + 2a + 3b + 2ab
First we have to add like terms:
2ab + 2ab - ab + 2a + 3b
4ab - ab + 2a + 3b
3ab + 2a + 3b
Here is your answer!
