To estimate a decimal to the tenths place, you have to round the number from the hundredths place. It all depends on the hundredths place to round a decimal to the tenths place. Let's say that you have a math problem and the answer is 10.46574658, but it says to round to the tenths place. So, you take the first four numbers from the answer, which would be 10.46, go to the tenths and the hundredths. If the number in the hundredths place is greater than 5, round the tenths number up. If the number in the hundredths place is less than 5, it stays the same. So with the number 10.46, the number in the hundredths place is greater than 5, so you round the number in the tenths place up, which becomes 10.5.

Answer:
The answer is 9
Step-by-step explanation:
56+(3x+7)=90 (In the picture it shows a 90 degree angle.)
Then, you can start solving the equation.
90-56=34
3x+7=34 (Subtract by 7)
3x=27 (Divide by 3 on both sides)
x=9
To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:
g(x) = -5x + 13
g(-1) = -5(-1) + 13
Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:
g(-1) = -5(-1) + 13
g(-1) = 5 + 13
g(-1) = 18
Therefore, your answer is 18.
Hope this helps!
THE ANSWER IS SUPPOSED STAY THE SAME.
