Answer:
<u>The answer is option C. 6a-7</u>
Step-by-step explanation:
Given that
5(3a-1)-2(3a-2)=3(a+2)+v
Solve for v
∴ v = 5(3a-1)-2(3a-2) - 3(a+2)
∴ v = 15a - 5 - 6a + 4 - 3a - 6
∴ v = 15a - 6a - 3a - 5 + 4 - 6
∴ v = 6a - 7
<u>So the answer is option C. 6a-7</u>
They are different because 738 is greater than 649 . There both not the same numbers.
B - 45 because 27 divided by 6 is 4.5 and then 10x4.5=44
Answer:
No, the solution is -3.
Step-by-step explanation:
3y+10=-5y-14
We move all terms to the left:
3y+10-(-5y-14)=0
We get rid of parentheses
3y+5y+14+10=0
We add all the numbers together, and all the variables
8y+24=0
We move all terms containing y to the left, all other terms to the right
8y=-24
y=-24/8
y=-3
Answer: 4. 9 + 7n - 3
3. 62
Step-by-step explanation:
Given statement: nine more than the product of seven and a number decreased by three
Let n be the number.
Then, required expression:
Correct option is 4.
When n= 8 ,
The value of expression =
Hence, value of the expression when n = 8 is 62.
Correct option is 3.
