<span>Given: 4y =2x-10, and y=6
Substituting for y in the equation gives 4(6) = 2x-10 or 24 = 2x-10
Adding 10 to both sides of the equation 24+10 = 2x - 10+10
34 = 2x
Dividing both sides by 2 34/2 = 2x/2
Answer 17 = x</span>
If you find the difference between 3 and 1 you would get 2 and then if you found the difference of 7 and 3 you would get 4. So basically the difference of the numbers is doubling. Hope this helps!
The answer is -3 because
-|28|= -28 now the problem looks like -28+(-5)^2
(-5)^2=25
-28 +25= -3
Answer:
2.79 * 10^4
Step-by-step explanation:
6.4 x 10^3+ 1.4 x 10^4+ 7.5 x 10^3
The exponents need to be the same
6.4 x 10^3+ 14 x 10^3+ 7.5 x 10^3
Add the numbers
6.4 + 14+ 7.5 =27.9
Multiply by the exponent
27.9 * 10 ^3
But this is not in scientific notation
Move the decimal one place to the left and add one to the exponent
2.79 * 10^4
