Hey. Let me help you out

First, let's rewrite the equation in order to minimize confusion. The way you wrote it makes it hard to vision it.

7d^2+10d=3

Now, we just replace the variable d with a value we have.

7(3^2)+10

Three to the power of two is going to equal to 9.

7*9+10

Seven times nine is 63.

63+10

Finally, 63 plus 10 is going to be 73.

Answer is 73

Y = 0.115x + 0.0045 , y = 0.499x – 0.22<br> solve for x
enyata [817]

Answer:

x=0.5612

Step-by-step explanation:

-Given the functions:

y=0.115x+0.0045\ \ \ \ ...i\\\\y=0.499x-0.22\ \ \ \ \ ...ii

We subtract equation i from ii to eliminate y and solve for x:

ii-i\\\\0=0.384x-0.2155\\\\0.384x=0.2155\\\\x=0.5612

Hence, the value of x is 0.5612

form a 6 digit number divisible by 1 first 2 divisible by 2, first 3 digits divisible by 3, first 4 digits divisible by 4, first
photoshop1234 [79]

Answer:

111111

Step-by-step explanation:

Digit 1: This can be any digit as all numbers are divisible by 1. I picked 1 because it was simplest.

Digit 2: The total needs to be divisible by 2, so I picked my total to be 2. I knew I already had 1 from the previous digit, so 2-1 =1 was my next digit.

Digit 3: The total must be divisible by 3, so I picked my total to be 3. I already had 2 from the two previous digits, so 3-1 = 1 was my next digit.

I hope you get the idea now, it follows the same pattern for the rest of the numbers.

Hopefully this helps, any questions let me know :)
