Answer:
D
Step-by-step explanation:
Given
- 4(x - 6) + 3(a - 7)
distribute the first parenthesis by - 4 and the second by 3
= - 4x + 24 + 3a - 21
= - 4x + 3a + 3 → D
Answer:
1)
2)
Step-by-step explanation:
1) The given equation is
We need to solve this for a.
In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.
Using the triangle and the operations (× and ÷), we get
Therefore, the required answer is
.
2) The given equation is
We need to solve this for m.
In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.
Using the triangle and the operations (× and ÷), we get
Therefore, the required answer is
.
Let X = smallest angle
largest 3x
middle=2x. add the 3 angles of any triangle and you get ,180
x+2x+3x=180
6x=180
x= 30
smallest =30
middle=60
largest=90
Answer:
C
Step-by-step explanation:
Answer:
m/8
Step-by-step explanation:
the equation would be 8y/8 =y and x/8= x/8. y=x/8 so you would start the line at 0 and count 8 units to the right and 1 unit up
