a-b=2.......(2)

Adding equiation (1)&(2), we get

2a=8

a=4

putting value of a in equiation (1), we get

4+b=6

b=6-4=2

therefore a=4 and b=2

Show how to solve the problem 378×6 using place value with regrouping. Explain how you knew when to regroup
nekit [7.7K]
<span>1. 6 (378) = 2268 = (189 + 189)6


Properties are:
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>

Arby’s sells brisket last year there was drought and farmers were able to raise fewer cows is this a change in supply or demand
kiruha [24]

This is a change in both supply and demand. Due to farmers raising fewer cows the supply of cows goes down. Because there is more of a need of cows due to the shortage the demand or need for them goes up. Due to the limited amount of cows and the high demand prices will go up.

There are 48 cards in a pack and each card is either red or black.
Anon25 [30]

Answer:

Step-by-step explanation:

Red:black = 1:1

Red cards = x

Black cards =x

x + x = 48

2x = 48

x = 48/2

x = 24

No. of red cards = 24

No of black cards = 24

Now 8 red cards are removed

So, No. of red cards = 24 - 8 =16

Red: Black = 16:24

=\frac{16}{24}=\frac{2}{3}

Red: Black = 2:3
