That’s the answer for you’re question
Answer:
Step-by-step explanation:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
Answer:
≥
Step-by-step explanation:
1 1\4x2 1\5 = 2 3/4
5/6 x 2 1/5 = 1 5/6
Answer:
Step-by-step explanation:
If we write the inequality out, we get this:
x <1/4
(
3
x
+
4
)
Now we just need to solve for x. Multiplying both sides by 4 yields:
4
x
<
3
x
+
4
Subtract 3x from both sides:
x
<
4
So any number less than 4 will work!
Since Celsius can go into the negative, the equation is;
2° - 12° = x.
x = -10°
