True this is because of the number of angles a quadrilateral has which is 4
Answer:
(6*3)^1 - 2(4+5)
Step-by-step explanation:
This is pure logic, so there is no step-by-step explanation.
X + 5y - 10 = 0
x = 2y - 8
Substitute the value of x in the 2nd equation to the 1st equation.
2y - 8 + 5y - 10 = 0
7y - 18 = 0 This is the resulting equation in its simplest form.
Find the value of y to get the corresponding value of x.
7y -18 = 0
7y = 18
y = 18/7
y = 2 4/7
x = 2y - 8
x = 2 (18/7) - 8
x = 36/7 - 8
x = 36/7 - (8 * 7/7)
x = 36/7 - 56/7
x = (36-56)/7
x = -20/7
x = -2 6/7
to check:
x + 5y - 10 = 0
-20/7 + 5(18/7) - 10 = 0
-20/7 + 90/7 - 10 = 0
-20/7 + 90/7 - (10 * 7/7) = 0
-20/7 + 90/7 - 70/7 = 0
(-20+90-70)/7 = 0
0/7 = 0
0=0
The <em>correct answers</em> are:
B) ∠R is congruent to ∠C; C) ∠B is congruent to ∠Q; E) BC is congruent to QR.
Explanation:
Using the congruence statement, we can state that corresponding elements of the triangles are congruent. In the statement, ∠R matches ∠C; ∠B matches ∠Q, and side BC matches side QR.
