Answer:
x = 29
y = 13
Step-by-step explanation:
Write 2 equations:
x + y = 42
x - y = 16
Isolate x in the first equation:
x = 42 - y
Substitute this in for x in the second equation:
42 - y - y = 16
42 - 2y = 16
solve for y:
-2y = -26
y = 13
Plug in 13 for y in either equation:
x + 13 = 42
Solve for x:
x = 29
Answer:
0.5 inch on the drawing
Step-by-step explanation:
The following information is missing:
<em>The scale factor of the drawing to the actual flag is represented by the ratio 1:18. </em>
This scale factor means that 1 inch on the drawing are equivalent to 18 inches o
n the actual flag. We want to know the height on the drawing, given that a height of 9 inches is drawn on the actual flag. The following proportion must be satisfied:
1 inch on the drawing / x inch on the drawing = 18 inches o
n the actual flag / 9 inches o
n the actual flag
x = 9/18 = 0.5 inch on the drawing
Answer:
In this problem, I can not tell what is V, so I will answer it in a general way.
A polynomial is something of the form:
a*x^5 + b*x^4 + c*x^3 + d*x^2 + e*x + f
a, b, c, d, e, and f are real numbers and constant.
Where the degree of the polynomial is equal to the greatest power (in this case 5).
You write:
4x^2 + 3Vx + 5
Now, if V is a real number, then we have that this is a polynomial of degree 2.
Because we can write this as:
4*x^2 + (3V)*x + 5
So the answer is true.
Now, if V is a variable or an operation, the answer will be false.
Answer:
shiii
Step-by-step explanation:
Less than 90° = acute
more than 90° = obtuse
equal to 180° = straight
more than 360° = reflex
