Mathematics
1 answer:
Alla [95]3 years ago
4 0

5-x÷3=-7

Add 3 to both sides of the equation.

5x=3+7

Divide each term by 5 and simplify.

Divide each term in 5x=10 by 5

5x/5=10/5

Reduce the expression by cancelling the common factors.

x= 10/5

Divide 10 by 5

Answer <em>x </em>=2

What is the simplest form of 4a + 8b/12​<br> Step by step pls
shutvik [7]

Answer:

4a + 2b/3

Step-by-step explanation:

focus on 8b/12 first:

factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3

then, go back to 4a:

4a is in its simplest form, it can't be factor

therefore, plus 4a and 2b/3 = 4a + 2b/3

Which point on the graph shows the price of 6 ounces of cheese? Use the formula y=x÷2 to find y when x is 6.
Gwar [14]

Answer: The required point is A(6, 3) in the attached graph.

Step-by-step explanation:  We are to find the point on the given graph that shows the price of 6 ounces of cheese.

The formula to be used is given by

y=x\div 2\\\\\Rightarrow y=\dfrac{x}{2}~~~~~~~~~~~~~~~~(i).

Given that,

when x = 2 then y = 1. That is, price of 2 ounces of cheese is $1.

when x = 7 then y = 3.5. That is, price of 7 ounces of cheese is $3.5.

when x = 14 then y = 7. That is, price of 14 ounces of cheese is $7.

Therefore, these points satisfy the given relation (i).

Hence, if x = 6, then from equation (i), we have

y=\dfrac{x}{2}=\dfrac{6}{2}=3.

Thus, the price of 6 ounces of cheese is &3. This gives that the required point is A(6, 3) on the graph attached below.

3(2.4−1.1m)=2.7m+3.2
telo118 [61]

Hello again!

First, distribute the 3 to the parenthesis, so you get 7.2-3.3m=2.7m+3.2. Next, subtract 3.2 from both sides to get m's on one side. Then you have 4.2-3.3m=2.7m. Next, add 3.3m to both sides so you can solve for m. Now you have 4.2=6m. Then, divide 4.2 by 6, and m=.7

Hopefully this helps! Let me know if you have any questions
