1) 6x+(5x-8)
Now combine like term
11x-8

2) (2-x)-3(6 + 8x)-12
distribute the negative sign and the -3
-2 + x - 18 - 24x - 12

then you have to combine like terms

Use the zero product property to find the solutions to the x² + 12= 7x

Answers

x^2 + 12 = 7x

x^2 - 7x + 12 = 0

(x - 3)(x - 4) = 0

x - 3 = 0 or x - 4 = 0

x = 3 or x = 4

What is the answer to 3(5x+1)+5(x+6)

Answers

3 ( 5 x + 1 ) + 5 (x + 6 )

3* 5 x + 3 *1 + 5*x + 5*6

15 x + 3 + 5 x + 30

15 x + 5x + 3+30

= 20 x + 33

hope this helps!.

You are using the distributive property. You want multiply both the 5x and the 1 by 3 to get 15x+3 and then you want to multiply both the x and the 6 by five to get 5x+30. You are left with 15x+3+5x+30. Add together your likes, so 15x and 5x and 3 and 30. Your answer would be 20x+33. The easiest way to do you your math for equations like this is as following:

3(5x+1)+5(x+6)
15x+3+5x+30
20x+33

Jacob is solving the equation below using successive approximations.2^x-4=3^-x-2 He started from a graph where he found the solution to be between 1 and 2. Using the lower and upper bounds from the graph, Jacob did the following work for the first iteration. Step 1 Rewrite the equation so that it equals zero on one side. Step 2 Evaluate the rewritten equation at the lower and upper bounds. To find the solution that lies between 1 and 2, set these values as the lower and upper bounds while finding the solution. Step 3 Take the average of the lower and upper bounds. Step 4 Evaluate the rewritten equation at x = . Step 5 Since this value is positive, replace the previous lower bound so that the bounds are now x = and x = 2. Where did Jacob make a mistake, and what was the error?

Answers

The mistake made by Jacob is; D: Jacob made a mistake at step 5. He should have used x=32 as the new upper bound.

How to Solve Successive Approximations?

In Mathematics, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.

In this question, Jacob started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that Jacob made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.

Step-by-step explanation:

The correct mixture of oil to gas in a weed eater is 1/2 pint of oil to 2 1/2 gallons of gas. how many pints of oil are needed for 10 gallons of gas?

Answers

1/2 pint of oil=2 1/2 gallons of gas

X pint of oil= 10 gallons of gas

X= (10*0.5)/2.5

X= 2 pints of oil

Final answer:

To find out how many pints of oil are needed for 10 gallons of gas in a weed eater, we need to set up a proportion using the given ratio. By cross-multiplying and solving for x, we find that 1/4 pint of oil is needed.

Explanation:

To find out how many pints of oil are needed for 10 gallons of gas, we can use the given ratio of 1/2 pint of oil to 2 1/2 gallons of gas. First, we need to change the 2 1/2 gallons of gas to pints by multiplying it by 8 (since 1 gallon is equal to 8 pints). So, 2 1/2 gallons becomes 20 pints of gas. Now, we can set up a proportion using the ratios of oil to gas. The proportion will be (1/2 pint) / (20 pints) = (x pints) / (10 gallons).

To solve for x, we can cross-multiply and then divide: (1/2 pint) * (10 gallons) = (20 pints) * (x pints). Simplifying this gives us x = 1/4 pint of oil. Therefore, 1/4 pint of oil is needed for 10 gallons of gas.
