Answer:
x = 4
Step-by-step explanation:
We can find the answer to this by solving the equation:
3x - 4 = 8
3x - 4 + 4 = 8 + 4
3x = 12
x = 4
Answer:
V = 300 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here A = 15 and h = 20 , then
V = 15 × 20 = 300 cm³
Step-by-step explanation:
x+y=-2
x-y=-6
x=-2-y
(-2-y)-y=-6
-2-2y=-6
-2y=-4
y=2
x=-4
Based on the given coordinate grid, and the increment for each grid line, the coordinates of point A is ( fraction negative 1 and 1 over 4, fraction 3 over 4) or (-1¹/₄, ³/₄).
<h3>What are point A's coordinates?</h3>
The x-value of point A is said to be 5 grid lines to the left of y-axis. This means that the x value will be negative.
The increments are 1/4 so the x-value is:
= -1/4 x 5
= -1¹/₄
The y-value is given by the 3 grid lines above the x-axis which means that this value is positive:
= 1/4 x 3
= 3 /4
The coordinates of A are:
(-1¹/₄, ³/₄)
