Answer:
Step-by-step explanation:
-5 = -5x
1 = x
Ok it wants you to take three numbers that add to 20 and then those three numbers need to multiply together to make 90
so 15+3+2= 20
then 15 x 3= 45 and 45 x 2=90
so 15, 3 and 2 are possible numbers

Explanation:
So you want to start by finding the area of the big square.
We know the width of the big square is 60cm. The length of the big square is
19

24
+

=
56
Big square

W
=
56
⋅
60
=
3360
Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
Little square

=
816
The area enclosed in the area of the big square minus the area of the little square.

816
=
2544
So the area enclosed is
2544

Step-by-step explanation:
The possibile answer is 10 ÷ 6 = 1.6
B - 10 pages
To find this, first convert 2.5 hours into minutes. You should get the answer of 150 minutes.
Then, you need to divide by 20, or the amount of minutes and pages conversion we are given. With that, you'll get 7.5 You'll then need to multiply 7.5 by 4/3, or 1.3, and get 9.75. You'll need to round that up to 10, aka B.
Hope this helps!
