Answer:
250
Step-by-step explanation:
You multiply 1 by 5 to get the 5".
Multiply 50 by 5 (the same number you multiplied the 1 by to get the 5)
50×5=250
X=22
(X+1)+ (3x+1)= 90
4x+2=90
4x=88
x=22
Answer: it’s the first one.
Step-by-step explanation:
Answer:
(a) 3x+28+5x+52+2x-10=180 (∠ sum of Δ)
10x+70=180
10x=110
x=11
(b) ∠C = 2x-10
= 2(11)-10
= 12°
5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.
So you all need to do is replace each letter by its value and do the calculus:
5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13
So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)
Hope this helps! :)
