Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
Answer:
$2
Step-by-step explanation:
You can solve this quickly by finding the difference in prices first.
7.49 - 6.99 = .50 difference
Now - multiply 4 shirts by .50 = $2
That is the SAVINGS for 4 shirts at the cheaper place
The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.
