Answer:
a = 25 , b = 14
Step-by-step explanation:
For A
a/5 + 3 = 8
a/5 = 8 - 3
a/5 = 5
Cross multiply
a = 5 * 5
a = 25
For B
3b/7 - 1 = 5
3b/7 = 5 + 1
3b/7 = 6
Cross multiply
3b = 42
b = 42 / 3
b = 14

Answer:
<h2>B. Standard</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The standard form of an equation of a line:
The general fom of an equation of a line:
We have the equation 3x - 2y = 4 in standard form.
First we have to know the formula of the volume f each of the solids,
<span>V of sphere = 4/3 pi r^3
</span><span>Volume of Cylinder = pi r^2(2r)=2pi r^3
</span><span>Volume of cone = 1/3 pi r^2(r)=1/3 pi r^3
</span>
The surest and easiest way we can answer this is actually assigning values. We first assign values to r hence we would get the volume of the sphere and rest of the solids (cylinder and cone). You then compare your answers to that of the sphere, and you should get your answer.
Answer:
C:
Step-by-step explanation:
Both angles add up to 180°
<BCG + <BFG = 180°
2x+146+4x+238=180
6x+384 = 180°
6x = 180-384
6x = -204
Dividing both sides by 6
x = -34
