the sum of the interior angles of a quadrilateral is 360°
[360 - (40 * 2)] : 2 =
280 : 2 =
140°
-------------------------------
140 + 140 + 40 +40 = 360°
Answer: -4/3= -1.3 repeating
Step-by-step explanation:
6g-9+5-3g -9+5= -4 6g-3g= 3g 3g/3 cancels out. -4/3= -1.3 repeating
Answer:
The value of a is -2
Step-by-step explanation:
We are asked to give the value of a
We are provided with some information
We are given slope to be 4
And two points ( -1 ,-1) and
( a, -5)
Given the formula for slope
m = y_2 - y_1 / x_2 - x_1
Points ( -1 , -1)
(a, -5)
x_1 = -1
y_1 = -1
x_2 = a
y_2 = -5
Inserting the values given into
m = y_2 - y_1 / x_2 - x_1
= -5 - (-1) / a - (-1)
= -5 + 1 / a + 1
= -4 / a + 1
We are given the slope to be 4
i. e. m = 4
4 = -4 / a + 1
Cross multiply
4( a + 1) = -4
Open the bracket with 4
4a + 4 = -4
Collect like terms
4a = -4 - 4
4a = - 8
Divide both sides by 4 to get the value of a
4a / 4 = -8/4
a = -2
Therefore, x_2 = -2
the value of a = -2
2 of the necklaces are blue.
Because she has 8 necklaces in total and 1/4 of those 8 are blue, you would divide 8 by 4.
1/4 of 8 is equal to 2
