Answer:
x=2
Step-by-step explanation:
Answer:
97.5
Step-by-step explanation:
Cross multiply
2 * x = 2x
15 * 13 = 195
2x = 195
2x/2 = 195/2
x = 97.5

Answer:
Parallel line:

Perpendicular line:

Step-by-step explanation:
we are given equation 4x+5y=19
Firstly, we will solve for y

we can change it into y=mx+b form


so,

Parallel line:
we know that slope of two parallel lines are always same
so,

Let's assume parallel line passes through (1,1)
now, we can find equation of line

we can plug values

now, we can solve for y

Perpendicular line:
we know that slope of perpendicular line is -1/m
so, we get slope as

Let's assume perpendicular line passes through (2,2)
now, we can find equation of line

we can plug values

now, we can solve for y

Answer:
For the shape you must do 3*3*3 + 2*2*2 + 1 unit cubed, or 36 units^3
For Jessy's jewelry box, you must multiply the side lengths, 3*10*3, or 90 inches^3
