Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
Answer:
x= -16
Step-by-step explanation:
-3x-8/ 4 = 10
Here we can try to isolate x and so we have to first multiply 4 on each side.
-3x-8= 40
Then we can add the 8 to each side.
-3x= 48
Next, divide the -3 onto each side and we can get the answer!
x= -16
50x32=1600 then u divide it by 2 and get 800
Answer:
- Q1. 86°
- Q2. B(2,0), D(3,1)
Step-by-step explanation:
Q1
<u>The angle of rotation is twice the angle of intersection:</u>
Q2
<u>Dilation by a scale factor of 2 resulted in:</u>
- (x, y) → (2x, 2y) for each point C' and D'
<u>The endpoints of the original segment are:</u>
- C = (4/2, 0/2) = (2, 0)
- D = (6/2, 2/2) = (3, 1)
Correct choice is B
