X and y are the numbers
y>x
sum (addition) of twice a number (2x) and larger number (y) is (=) 145
2x+y=145
difference between them is 55 (y is bigger so it would be x is subtracted from y)
y-x=55
so the equations are
2x+y=145 and
y-x=55
we could add x to both sides in the 2nd equation to obtain
y=x+55, but that doesn't really represent that the difference is 55, though they are the same euation
so I would say C and D only
Answer:
See below ~
Step-by-step explanation:
For the question with colored rectangles, it asks to find the area.
The area can be found by multiplying the dimensions of the rectangle.
Blue rectangle :
- A = 10 ft. x 6 ft.
- A = <u>60 ft²</u>
<u></u>
Green rectangle :
- A = 12 cm. x 8 cm.
- A = <u>96 cm²</u>
<u></u>
Question 13 :
- Here, we are given 2 rows and 7 columns
- Take them as the dimensions
- Hence, area = 2 x 7 = <u>14 square units</u>
