Answer:
Step-by-step explanation:
The angle at E is 90 degrees.
All tangents of a circle always meet the radius at a 90 degree angle.
90 + 67 + G = 180o All triangles have 180 degrees. Combine left.
157 + G = 180o Subtract 157 from both sides.
157 - 157 + G + 180 - 157
G = 23
Required expression is x/9 - 7
Write the 2 equations:
5x-2y=18
-5x+3y=-22
You can see that the coefficients of x are opposites, so you can add them(the 2 equations) to eliminate x.
Adding them, you get:
y=-3
So now that you know y, you can substitute the value of y into one of the original equations. Let's substitute it in the first one:
5x+6=18
Solving this, we get:
5x=12
x=12/5
x=12/5, y=-3
Answer:
m ∈ R
Step-by-step explanation:
- 1,84 - 2,3m = - 2,3(m + 0,8)
- 1,84 - 2,3m = - 2,3m - 1,84
m ∈ R
Answer:
Tyrel scored 30 and Diego scored 15
Step-by-step explanation:
This is because the ratio of the score is 2:1 (Tyrel : Diego)
and if you add that together you get 3
which means you have to divide 45 by 3 which gives you 15
and this means I part = 15
so with the ratio 2:1 you have to multiply 15 by each ratio
so 15 x 2 = 30 and 15 x 1 = 15
which gives you 30 and 15
