Answer:
a
Step-by-step explanation:
given
3(x - 2) < 18 ← distribute the left side
3x - 6 < 18 ( add 6 to both sides )
3x < 24 ( divide both sides by 3 )
x < 8 → a
Answer:
<h3> the first number is 5</h3><h3> the first second is 6</h3><h3> the first number is 1</h3>
Step-by-step explanation:
x - first number
2x - twice the first number
twice the first number exceeds the second number by 4 so:
2x-4 -the second number
y - the third number
the second number is equal to the sum of the first and third numbers:
2x-4 = x + y
x + y = 2x - 4
-x -x
y = x - 4 - the third number
the sum of three numbers:
x + 2x-4 + x-4 = 4x - 8
The sum of three numbers is 12 so:
4x - 8 = 12
+8 +8
4x = 20
÷4 ÷4
x = 5
2x-4 = 2•5 - 4 = 6
x-4 = 5 - 4 = 1
Check:
5+1 = 6
2•5 = 10, 10-4 = 6
Speed = distance / time
so ur speed = (3/5) / (3/8) = 3/5 * 8/3 = 8/5 or 1 3/5 miles per hr.
its the first answer choice
Subtract 4/7 on both sides to get b=-4/7-3. Then simplify.
Answer:
7.2
Step-by-step explanation:
Mean is when you add all the numbers together and divide them by the number of values there are in total.
There are 10 numbers, so find the sum of all the numbers and divide by 10.
= 72/10 = 7.2
