Yes you are doing it right
V<span>=(</span><span>4/</span><span>3)</span><span>πr^</span><span>3
R=radius
Diameter= 2 times R
so,
R=7 ft
plugging the values;
V=(4/3)(3.14)(7)^3
V=1436.02 Cubic feet</span>
Let
V-------------> total <span>vegetables in Priya's garden
T------------> total tomatoes </span>in Priya's garden
we know that
T=(2/5)V
Part A) <span>HOW many tomatoes are there I'd Priya's garden has.
1) </span><span>20 Vegetables?
</span>T=(2/5)*20----------> 20*2/5---------> 8 tomatoes
<span>the answer Part A1) is 8 tomatoes
</span>
2) x Vegetables?
T=(2/5)*x----------> x*2/5---------> (2/5)*x ----------> 0.40*x tomatoes
the answer Part A2) is (0.40)*x tomatoes
Part B) <span>Priya's garden has 6 tomatoes. How many total vegetables are there?
</span>T=(2/5)V-----------> V=5T/2--------> V=(5*6)/2--------> V=15 vegetables
<span>
the answer part B) is </span>15 vegetables<span>

I'll solve it by substitution instead of graphing.
x + y = 2
y = (1/2)x + 5
Substitute equation 2 into equation 1.
x + (1/2)x + 5= 2
(3/2)x + 5 = 2
(3/2)x + 5 - 5 = 2 - 5
(3/2)x = -3
(2/3) * (3/2)x = -3 * (2/3)
x = -2
x + y = 2
-2 + y = 2
y - 2 = 2
y - 2 + 2 = 2 + 2
y = 4
x = -2
y = 4
(-2,4)
Your answer is B) (-2,4).
Multiply all the numbers by what you see on the screen and the six the side and then divide it into a equal amount.
