Answer:
420in^2
Step-by-step explanation:
Given data
Length of base= 6 in
Widht of base= 70 in
We know that area= Length*Width
substitute
Area= 6*70
Area= 420 in^2
Hence the area of the base is 420in^2
Answer:
5(3x - 4)
Step-by-step explanation:
5(3x - 4)

Answer:
no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
Step-by-step explanation:
Let the no of 2kg disks be a.
Let no of 5 kg disks be b.
2a+5b=29
a+b=10
Using substitution, we have
2(10-b) + 5b=29
20-2b+5b=29
20+3b=29
3b=9
b=3
So no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
Tens refers to the unit 10,
This means that 45 10s is equal to:
45*10 = 450
Hope this helps! :)
Twice means times 2.
1) 2(ab) gives twice the product of a and b.
2) (2a)b gives the product of twice a and b.
