Steps ;
1) add the five to the 15 (since it’s a negative to the other side of the equal sign)
2) dived 2 from 2y and 20
3) y should equal 10
Answer:
x = 4√5
Step-by-step explanation:
The triangles are all similar, so corresponding lengths are proportional.
hypotenuse/short side = x/5 = (11+5)/x
x^2 = 80 . . . . cross multiply
x = 4√5 ≈ 8.94427
Answer:
2a-6=a
Step-by-step explanation:
The keyword "times" lets us know we need to multiply 2 and a and "less" shows us we need to subtract 6 from that.
Answer:
11
Step-by-step explanation:
Opposite sides are congruent at parallelograms. So x+16 must be equal to 2x+5. Solve the equation;
2x+5 = x+16
x = 11 .
