X-4=-11
move -4 to the other side
to get X by itself
sign changes from -4 to +4
X-4+4= -11+4
X= -11+4

Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>
Answer:
x = 8
Step-by-step explanation:
3x + 2 + 7x + 8 = 90
10x + 10 = 90
10x = 80
x = 8
Check: 3x + 2 = 3(8) + 2 = 26°
7x + 8 = 7(8) + 8 = 56 + 8 = 64°
sin 26 = cos 64
Answer:
52
Step-by-step explanation:
Let total plants = x
grape tomato: 1/5 of x=18; (1/5)*x=18; x=18*5=90
other plants other than grape tomatoes and cherry tomatoes = 90-18-20=52
