Answer:
u put 90 was that the answer
Step-by-step explanation:
Answer:
x=20
Step-by-step explanation:
We can use similar triangle to find x. Put the smaller triangle over the larger triangle.
11 10
-------- = ----------
121+11 10 +5x+10
Combine like terms
11 10
-------- = ----------
132 20+5x
Using cross products
11 (20+5x) = 132*10
Distribute
220 +55x = 1320
Subtract 220 from each side
220-220 +55x = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
The correct answer will be 0.00038
The easiest way to solve is if the exponent is positive you move the decimal to the right and if the exponent is negative the decimal moves to the left.
28 = x + (2x - 5)
28 = 3x - 5
+5 +5
33 = 3x
/3 /3
11 = x
On number is 11, the other is 17.
Check:
11(2)=22-5=17
Answer: 
Step-by-step explanation:
Slope of two lines that are perpendicular to each other is 1.
If one line is 
, then its slope = 3 [by comparing to the linear equation y= mx+c, here m=3]
Let n be the slope of the required line, then
Equation of line with slope n and passers through (a,b) is
Equation of line with slope n= 
and passes through point ( 0,-4) :
Hence, Required equation :
