Answer:
6+ 7/7 +7×7 - 7
using BODMAS
6+1+49-7
56-7=49
I would appreciate if my answer is chosen as a brainliest answer
A
We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.
The conjecture is that x = a + b. You should always find that to be true. C is the clincher.
Here's how you do that.
x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o
Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o
So we have two conditions that equal 180o. Equalities can be equated to one another.
a + b + c = x + c Subtract c from both sides.
a + b = x.
Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.
Summary
a cannot be solved without 28
b you should say that the two remote angles (a and b) will always total x
c The proof is provided for you.
Answer:
highliter=3,pen=2
Step-by-step explanation:
h-highliter
p-pen
2h+5p=16
4h+3p=18
2h=16-5p
2(16-5p)+3p=18
32-10p+3p=18
14=7p
p=2
2h=16-10
2h=6
h=3
Answer:
10 × 5
2 × 25
1 × 50
Step-by-step explanation:
The average speed for the entire journey will be given by:
average speed=(total distance)/(total time)
total distance=50+10=60 km
total time=4 hours
thus
average speed=60/4=15 km/hr
