Answer:
33.3
Step-by-step explanation:
The formula for area is length*width.
7.4*4.5=33.3
Write the Inequality
A number b times -16 is greater than 5.
A number b is a variable... b.
Times means multiply.
-16 is what you are multiplying b by.
Is greater than means the greater than symbol.
5 is what the past statements are greater than.
So this is the inequality.
-16b > 5
Solve the Inequality
You need to isolate b.
To do this, divide each side by -16. You do this because b is being multiplied by -16. You know that any number divided by that number equals 1, canceling the number.
-16b ÷ -16 = b
5 ÷ -16 = -5/16
So you get b > -5/16
So to make the inequality true, b must be more than -5/16.
Or as an inequality...
b > -5/16
Answer:
x = 7/12
Step-by-step explanation:
We start off by multiplying both sides by 4:
4(x-2) = 3(2-x)
Distribute the 4 and the 3:
4x - 8 = 6 - 3x
Bring all the terms with the x at the first side:
4x + 3x = 6 + 8
7x = 12
x = 7/12
Answer:
See below for answers
Step-by-step explanation:
1st angle = 2x
2nd angle = x
3rd angle = x - 8
Sum of the angles in a triangle = 180°
1st + 2nd + 3rd = 180°
2x + x + x - 8 = 180°
4x - 8 = 180°
4x = 188
x = 47°
Now substitute
1st angle = 2x = 2(47) = 94°
2nd angle = x = 47°
3rd angle = x - 8 = 47 - 8 = 39
Check: 94 + 47 + 39 = 180°
