Answers: 11-20
Step-by-step explanation: Step 1. Flip the equation Step 2. Add the number to both sides Step 3. Divide both sides by the number to get your answer.
1. v=10 2. m=7 3. r=-9 4. k=9 5. r=0 6. x=10 7. x=6 8. 9=3 9. m=-10 10. n=-10
11.p=0
12.x=10
13.b=4
14.n=0
15.p=2
16.x=8
17.m=8
18.x=3
19.n=-1
20.n=9
If the ratio is 4:1 , pencils being the 4 and erasers being the 1, there are 4 pencils for every 1 eraser. Now, substitute the 4 pencils for 20 pencils. How do you get to 20 from 4? multiply by 5. You multiply the 4 pencils by 5 to get 20, and u multiply the 1 eraser by 5 to get 5, so there are 20 pencils: 5 erasers
It’s decreasing from -1 to 1.
Answer:
as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition
such as
corresponding angles, AB//CD ,
alternate angles, AB//CD ,
interior angles, AB//CD
In my figure, a+b is always equal to 180degree if the X line is straight
a+b=180
imagine there is Y line which is parallel to the X line
c+d=180
a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)
then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
We suppose one children can receive x. Then grandson receive 1/4x. Total is 4x+8*1/4x=6x. After deducting the fees and taxes, the amount is 4.5-1.26=3.24 million. So x=3.24/6=0.54 million. So each grandchild get 0.54/4=0.135 million.
