Multiply the first equation my 2 and than subtract the two equations to eliminate x
6x+16y=60-
6x+7y=6
9y=54
Y=6
Then plug in y to one of the equations
6x+7(6)=6
6x+42=6
6x=-36
X=-6
X=-6 Y=6
Answer:
D. 1/2 ≈ 0.083
Step-by-step explanation:
So for the coin there is a 1/2 chance because there are two sides, and only one will be "right." For the side-sided dice, there is a 1/6 chance using the same thinking as the coin.
We can multiply them by each other,
1/2 * 1/6 = 1/12
So the correct answer is D. 1/2 *about* 0.083
I hope this helps, have a nice day! :D
Answer:
A. 107
Step-by-step explanation:
Angles 107 and b are corresponding angles,
Corresponding angles are equal.
So,
b = 107
3. Rule - 4 and below - round to a 0
5 and above - round to the number
A - 182.<u>8</u>86 - 182.900
B - 0.<u>4</u>59 - 0.500
C - 4.<u>0</u>6 - 4.10
D - 7.<u>9</u>6 - 8
E - 0.3<u>0</u> - 0.3
F - 3.<u>2</u>1 - 3.2
Let
y----------> the length of the rectangle
x---------> the width of the rectangle
P--------> perimeter of a rectangle
we know that
P=38 ft
[P]=2*[x+y]------> 38=2*[x+y]------> equation 1
y=5+x-------> equation 2
<span>substitute 2 in 1
</span>P=2*[x+(5+x)]---------> P=4x+10---------> the given equation
4x=38-10--------> 4x=28----> x=7 ft
y=5+7-----> y=5+7------> y=12 ft
the answer is
the width is 7 ft
