Answer:
4 13/30
Step-by-step explanation:
1 3/5 + 2 5/6
= 8/5 + 17/6
= 48/30 + 85/30
= 133/30
= 4 13/30
I used the substitution method.
The first equation is what I used: y=-6x+9.7
So I plugged in y in the second equation.
4x + 2(-6x+9.7)= 9.8
4x-12x+19.4=9.8
Combine like terms
-8x+19.4=9.8
Subtract 19.4 on both sides
-8x=-9.6
Divide by -8 on both sides and you get
x=1.2
If you wanted to find y use either equation and plug in for x with the value of x!
So it's basically 3x2x2x2
3x2=6
6x2=12
12x2=24

Given:
Figure of similar triangles.
To find:
The value of x and the measure of NR.
Solution:
In triangle RST and RMN,
(Vertically opposite angles)
(Alternate interior angles)
(By AA property of similarity)
We know that, corresponding sides of similar triangles are proportional.
On further simplification, we get
The value of x is 7.
Now,
Therefore, the value of x is 7 and the measure of NR is 12 units.
Answer:
X=-5
Step-by-step explanation:
Start by isolating the variable to one side. So from here we would add 68 to both sides. we will be left with -8 1/4x = -6.25x+10. Then add 6,25 to both sides to cancel on and get -2x=10. Divide both sides by -2 to get x=-5
