Answer:
Graphs
Step-by-step explanation:
X= # of multiple choice questions
y= # of word problem questions
EQUATION 1:
x + y= 25
EQUATION 2:
3x + 4y= 90
STEP 1:
solve for one variable in equation 1
x + y= 25
subtract y from both sides
x= 25 - y
STEP 2:
substitute x=25-y in equation 2
3x + 4y= 90
3(25-y) + 4y= 90
75 - 3y + 4y= 90
75 + y= 90
subtract 75 from both sides
y= 15 word problems
STEP 3:
substitute y value to find x
x + y= 25
x + 15= 25
x= 10 multiple choice questions
ANSWER: There are 15 word problems and 10 multiple choice questions.
Hope this helps! :)
Step-by-step explanation:
If angle 1 is 121 degrees, then angle 7 is 59 degrees. (same side exterior angles)
If angle 8 is 103 degrees, then angle 4 equals 103 degrees (corresponding angles) and angle 3 is 77 degrees. (to angle 4 supplementary angles)
If angle 5 is 116 degrees, then angle 3 is 64 degrees. (same side interior angles)
Try going with these⬇
1) 3 over 5
2) 1 and 1 over 2
3) 7 and 1 over 2
4) 3 and 1 over 7
