Step-by-step explanation:
make a negative and positive sign coordinate plane
plot it on -2
The answer is <span>b.3x + 15 = 55 - x
</span>
x - Jill's present age
y - dad's present age
<span>In 5 years, Dad will be three times as old as his daughter Jill will be then:
y + 5 = 3(x + 5)
</span><span>The sum of their present ages is 50:
x + y = 50
We have the system of two equations now:
</span>y + 5 = 3(x + 5)
x + y = 50
Let's rearrange the second equation:
If: x + y = 50
Then: y = 50 - x
Now, substitute y from the second equation (y = 50 - x) into the first one:
y + 5 = 3(x + 5)
50 - x + 5 = 3(x + 5)
50 + 5 - x = 3*x + 3*5
55 - x = 3x + 15
Rearrange it a bit:
3x + 15 = 55 - x
Therefore, the correct choice is b.
Answer:
the hunter should purchase three ounces of seeds and 7 ounces of dried fruit to satisfy the situation
Step-by-step explanation:
Let us assume the amount of seeds be x
And, the amount of dried fruit be y
Now the first equation would be
x + y = 10
y = 10 - x
And, the second one would be
1.50x + 2.50y = 2.20(10)
1.50x + 2.50y = 22
We can put the y value in second equation
1.50x + 2.50(10 - x) = 22
1.50x + 25 - 2.50x = 22
-x = 22 - 25
-x = -3
x = 3
and, y = 10 - 3
= 7
Hence, the hunter should purchase three ounces of seeds and 7 ounces of dried fruit to satisfy the situation
You could keep the "X" the same and add 5 t the "Y", so then it would be (2,8)
