If you only have 3 point problems you have a total of 3*30=90 points, since the test has 100 points you need 10 extra points, so 10 of those 3 point questions have to be changed to 4 point questions.
So 20 3-point questions and 10 4-point questions.
If I’m right a triangle = 180, so 104+32 = 136. Now 180-136=44 if it’s not a answer just redo my math because at the moment I have no paper.
35%=35/100=0.35
0.35x=42
divide both sides by 0.35
x=120
35% of 120 is 42
Answer=120
The point (a,b) is (5,7) . Therefore, the equation of the line is y=7 . (Brainliest?)
Answer:
the answer; 32÷36×100 will give the answer (d) -88.9%
