We can add in any order. So 5x+y is the same as y+5x
5x+y = 10
y+5x = 10
y+5x-5x = 10-5x ... subtract 5x from both sides
y+0x = -5x+10
y+0 = -5x+10
y = -5x+10
Answer: y = -5x+10
Note: this is in y=mx+b form where m = -5 is the slope and b = 10 is the y intercept
Answer:
It is a right triangle.
Step-by-step explanation:
Right triangles will always have a right angle equalling 90 degrees. The other two angles will always be 45 degrees.
Answer:
Volume of prism = 39 km cubed
Step-by-step explanation:
<u>IMPORTANT FORMULA: Volume of any prism = Area of base * Height </u>
<u />
In this case, <u><em>the area of the base</em></u> means <u><em>the area of the trapezoid. </em></u>
Area of trapezoid = base1+base2/2 * height
Area of trapezoid = 8+5/2 * 1.5
Area of trapezoid = 13/2 * 1.5 = 9.75
We already know that the height of the trapezoidal prism is 4 kilometers.
So, we have all of the values that are needed to correctly fill in the formula.
Volume of the prism = 9.75 * 4 = 39
Answer:
-4/15
Step-by-step explanation:
Answer:
The value of X<em> </em>is 6.
Step-by-step explanation:
5 + 3 + 7 + 9 = 24
30 - 24 = 6
X = 6
The difference is 6.
