This is really easy.
x-4=8
what it really is asking you is the value of x
Isolate x
take 4 to the other side. not -4 but positive 4
x=12
Answer:
i think it is a because it makes sense and also you wouldnt
Step-by-step explanation:
X=18 and y=10 because they are both 90degree angles therefore all you have to do is solve the equations: 5x=90 and 9y=90.
Let X = smallest angle
largest 3x
middle=2x. add the 3 angles of any triangle and you get ,180
x+2x+3x=180
6x=180
x= 30
smallest =30
middle=60
largest=90
Answer:
$425
Step-by-step explanation:
x = bench
x - 69 = garden table
x + (x - 69)=781
x + x - 69 =781
2x - 69 = 781
2x -69 +69 = 781 + 69
2x = 850
2x/2 = 850/2
x = 425
Bench = 425
