Five less than three times a number is 10

the number is 5

Step-by-step explanation:

we can put this into an equation

3*x - 5 = 10

this means 3 times a number and since the number is unknown we can use x.

now we can solve the equation we created .

3x - 5 = 10

3x = 10 + 5

3x = 15

x = 5

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
