Answer:
<h3>it's A you're right</h3>
Answer:
6.75 or 6 3/4
Step-by-step explanation:
First take the whole number and multiply that by 3.
2*3=6
Now, take the fraction and multiply that times 3.
1/4 as a decimal is 0.25. You can ignore the decimal point right now, but you have to remember it is there later.
So, whithout the decimal point, 25*3= 75.
Now, you add the decimal. The 75 is now 0.75, with the decimal.
Add the whole number and the decimal, and you have your answer!
6+0.75=6.75. As a fraction this is 6 3/4
Answer:
3y - 5
Step-by-step explanation:
We combine like terms. The y terms are 10y, -8y and y which combine to 3y. Think of it like having 10 items, take away 8 items but then add on 1 more. So we'd have 10-8+1 = 2+1 = 3 items overall. Replace "Items" with y and we have 10y-8y+1y = (10-8+1)y = 3y
The other terms are constant terms as they dont have any variables attached to them. These terms are -3, 4 and -6 which combine to -3+4-6 = 1-6 = -5
In summary, the y terms combine to 3y while the constant terms combine to -5. Put together, the fully simplified answer is 3y-5
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
1a) if all the angles are perpendicular, they all =90°
