Answer:
a+4=11b
Step-by-step explanation:
Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.
for example a( b+c) = ab+ac
Therefore, applying distributive property in asked eapression
12(2a - 6b+ 8) = 21(2a−6b+8)
24a+72b+96 = 42a-126b+168
198b=18a+72
9a +36=99b
3a+12=33b
a+4=11b
Solution:
1) x=-\frac{14}{5}
Decimal Form: -2.8
Done!
Solution:
2) y=0
Done!
So acting, eh?
you can walk 10 steps in 5 seconds
how many steps can you walk in 25 seconds?
(walk to test this thingie)
reasoning is 25 is 5 times 5 so 10 times 5=50 so 50 steps
2.504 x 10^1
Significant digits has one digit in front of the decimal and you multiply a 10 to the power of the amount of moves made and the direction. In this case, we moved it over 1 and to the left direction. The 1 move is the exponent on the 10 and the direction of left is a positive exponent.
