Answer:
5x+17
Step-by-step explanation:
1.) distribute/multiply the 2 into (x+7) and you get 2x+14
2.) then do the same with the 3 into (x+1) and you get 3x+3
3.) finally, just combine the like terms which are 3x and 2x (just add them), and 14 and 3 (again add them) and your final answer should be 5x+17

Answer:
C. 22/7
Step-by-step explanation:
You may be aware that 22/7 is a value used to approximate π almost as often as is 3.14.
__
In case you actually want to carry out the calculations, you have ...
C = πd
π = C/d
π ≈ (60 3/50)/(19 11/100) = (3003/50)/(1911/100) = 6006/1911 = 22/7
π ≈ 77/(24 1/2) = 77/(49/2) = 22/7
π ≈ (86 9/10)/(27 13/20) = (869/10)/(553/20) = 1738/553 = 22/7
π ≈ 99/(31 1/2) = 99/(63/2) = 22/7
Answer:
If its temperature is below 0 °C, then water is frozen.
Step-by-step explanation:
The converse of <em>if A then B</em> is <em>if B then A</em>.
Here, we have ...
A = water is frozen
B = its temperature is below 0 °C
so the converse is ...
If its temperature is below 0 °C, then water is frozen.
Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
