River C : 200 + x
River D: x
200 + x + x = 5,540
combine like terms
200 + 2x = 5,540
subtract 200 from both sides
2x = 5,340
divide both sides by 2 to isolate the variable
x = 2, 670
River C: 200 + x = 200 + 2,670 = 2,870
River D: x = 2,670
2,870 + 2,670 = 5,540
Answer:
-5
Step-by-step explanation:
f (x) = 4 - x^2

= 4 -(9)
= -5
Answer:
2x square -25x + 7
Step-by-step explanation:
a square - (b+c)
(3x-4)square - {(x+7)+(x square+2)}
3x square-2.3x.4+4 square - (x+7+x square+2)
3x square - 24x + 16 -x - 7 - x square - 2
3x square - x square -24x - x + 16-7-2
2x square-25x+7
or,
x(2x - 25)+7

Answer:
These quotients are different because of what division means.
Step-by-step explanation:
When you divide you start with a total and break it into equal groups. If you started with three and broke them into groups of 1/5, that is different then starting with 1/5 and breaking into three groups.
If you had 3 cups of Chex mix and made servings of 1/5 of a cup. How many servings could you get? This is 3 divided by 1/5.
If you want to put tomatoes in 1/5 of your garden and you have 3 different tomatoes you want to plant. What fraction of the original garden will each type of tomato be in if they are evenly distributed.
