Which statement must be true to prove m∠1 + m∠2 + m∠3 = 180°? Triangle ABC is drawn such that point C lies on line m and side AB lies on line n. Line m and line n are parallel to each other. Measure angle A is marked as 1, angle C is marked as 3 and exterior angle to angle C is marked as 2. A. m ∥ n B. m∠1 + m∠2 = 180° − m∠3 C. m∠1 + m∠2 = 90° D. m∠1 = m∠2 = m∠3

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
