im just going to copy and paste the correct ones and their answers:
<u>Problem: The sum of twice a number and −6 is 9 more than the opposite of the number. Find the number.</u>
<u>Equation: 2n − 6 = 9 − n</u>
<em>n = 5</em>
<u>Problem: Anna drove 450 km in 6 hours. Find her rate of travel.</u>
<u>Equation: 450r = 6</u>
<em>r = 75</em>
<u>Problem: Three times a number increased by 44 is the same as the opposite of the number. Find the number.</u>
<u>Equation: 3n + 44 = −n</u>
<em>n = -11</em>

3(2x - 1) > = 4(2x - 3) - 3
6x - 3 > = 8x - 12 - 3
6x - 3 > = 8x - 15
6x - 8x > = -15 + 3
-2x > = -12
x < = -12/-2
x < = 6
the incorrect one is : A number line with a closed circle on 6, shading to the right
Answer:
a= 121°
b=62°
c=59°
Step-by-step explanation:
I first found b because they are vertical angles
Because I know the measure of angle b I take 180 (total sum of a triangle) and subtracted 62 from 180 which gave me 59 and because both base angles are equal to each other I divided 118 by 2 which gave me 59. Giving me the measure of angle c.
By adding angles b and c they would give me the measure of angle a.

Answer:
Step-by-step explanation:
Given: ΔABC and ΔFGH are right angles, BA||GF; BC ≅ GH.
To prove: ΔABC ≅ ΔFGH
Proof:
Step 1. ∠ABC ≅ ∠FGH (Because all right angles are congruent)
Step 2. ∠BAC ≅ ∠GFH (Because corresponding angles of parallel lines are congruent)
Step 3. BC ≅ GH (Given)
Step 4. From ΔABC and ΔFGH
∠ABC ≅ ∠FGH
BC ≅ GH
∠BAC ≅ ∠GFH
thus, by ASA rule of congruency, ΔABC ≅ ΔFGH.
