I do believe the answers in a row are A: x, B: 40, C: 12, D:y
Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *

= 67
0.3 *

= 30
Divide as usual.
67 / 30 = 2

So, the answer is 2 1/3.
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
First you cross multiply.
2*(b-4)=6b
Then distribute the 2.
2b-8=6b
Minus 2b from each side.
-8=4b
Divide each side by 4.
-2=b
So -2 is your answer.
