Hello there.

Question: <span>Twice the sum of a number and two is sixteen. Find the number.

Answer: Put it into an equation:
2 ( x + 2 ) = 16.
Expand the parentheses:
2x + 4 = 16
Solve the equation:
16 - 4 = 12
12 / 2 = 6.
The number is 6.

Please Help. It Is A Or B for answers!

Anna35 [415]

Answer:

Step-by-step explanation:

A: x = 12-4 = 8

B: x = 12/4 = 3

No wonder you asked for help. Some of the questions don't make sense!

x+3 = 9 ⇒ x=6, which doesn't match either A or B.

3·x = 9 ⇒ x=3, which matches B

9 = 3·x is the same as the previous equation, i.e., B.

3+x = 9, doesn't match either A or B.

x = 9-3, doesn't match either A or B

x = 9÷3 ⇒ x=3, which matches B

x+x+x = 9 ⇒ x=3, which matches B

I'm guessing that there is an error in tape A, and x should be 6, not 8.

Help find the equivalent fraction with the correct steps please !

Nat2105 [25]

Answer:

: = ÷

$\frac{-2}{5}*\frac{6}{-1} : \frac{5}{-2} = \frac{-12}{-5} : \frac{5}{-2} = \frac{12}{5}*\frac{-2}{5}=\frac{-24}{25}$

An equivalent fraction is -24 over 25.

Answer:

About 35 trees in a state park are infected with insects

Step-by-step explanation:

we know that

7 out of 190 trees are infected with insects

using proportion

Find out about how many of the 950 hemlock trees in a state park are infected with insects

$\frac{190}{7}=\frac{950}{x} \\\\x=7(950)/190\\\\x= 35$

therefore

About 35 trees in a state park are infected with insects
