Travis gave away 40
Divide 9 from 360 will give you your answer.
Equation A : x + z = 6
Equation B : 2x + 3z = 1
Possible step used in eliminating in z-term.
Multiply equation A by -3.
-3(x +z) = -3(6)
-3x - 3z = -18
-3x - 3z = -18
<u>2x + 3z = 1</u>
-x = -17
<u>÷ -1 ÷ -1
</u>x = 17
Answer:
x = 8
Step-by-step explanation:
To find the possible value of x in the given trapezoid MNOP with median QR, recall that one of the properties of a trapezoid is that the median length = ½ of the sum of the length of the parallel bases
Thus, ½ of [x + (3x + 8)] = 20
Let's find x
½*[x + (3x + 8)] = 20
½*[x + 3x + 8)] = 20
½*[4x +8] = 20
Multiply both sides by 2
4x + 8 = 20*2
4x + 8 = 40
Subtract 8 from both sides
4x = 40 - 8
4x = 32
Divide both sides by 4
x = 32/4
x = 8
Answer:
No, it's not long enough
Step-by-step explanation:
The perimeter of the square is 4/5. P=4s where s is the side length. 4/5 is larger than 5/8, so there will not be enough lights to cover the whole perimeter.
