the equation is 2x-1 right so all you have to do is plug and go
2x-1
2x10-1
20-1
19
so your answer would be A)19

Answer:
Step-by-step explanation:
Side lengths in an isosceles right triangle have the reduced ratios ...
1 : 1 : √2
Yours have the ratios ...
9 : x : y
If you multiply the reduced ratios by 9, you can find the values of x and y.
9 : 9 : 9√2 = 9 : x : y
x = 9
y = 9√2
Answer: 135
Step-by-step explanation:
m<D+45=180
the measure of <D is 135
x = 3
Step-by-step explanation:
First we would simplify the left hand side of the equation by expanding the brackets
so 2(4-3x) = 8-6x and
5(2x-3) = 10x-15
This gives the left hand side as 8-6x+10x-15. So the overall equation becomes
8-6x+10x-15 = 20-5x.
Grouping the unknown values on one side and integers on one side of the equation gives us
8-15-20=6x-10x-5x (note the sign changes when numbers and unknown values are moved to the other side of the = sign
Solving further, -27 = -9x i.e x = -27/-9 = 3
Hence x = 3
