Hi there!

Answer:
The answer is "Subtract 10, then divide by −4"

Explanation:
To solve a linear equation (for x) we need to isolate the variable (x). First we need to bring the variables to the left side (in this case, it is already on the correct place). Next up is bringing all the integers to the right side. Therefore, we must first subtract 10. Our final step is dividing by the number that is placed in front of x (in this case divide by −4)

Solving the equation:
−4x + 10 = 2
First subtract 10 (from both sides of the equation)

−4x = −8
Divide by −4

x = −8 / −4 = 2
Therefore, the solution is x = 2

I hope this anwer helps you!

Evaluate each expression for g = -7 and h = 3 and match it to its value.

Arturiano [62]

Answer:

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Step-by-step explanation:

Given values of g and h are:

g = -7

h = 3

1. gh

The two numbers are being multiplied

Putting the values

$gh = (-7)(3) = -21$

2. g^2-h

Putting the values

$=(-7)^2-3\\=49-3\\=46$

3. g+h^2

Putting the values

$= -7 + (3)^2\\=-7+9\\=2$

4. g+h

Putting the values

$= -7+3\\=-4$

5. h-g

Putting the values

$= 3 - (-7)\\=3+7\\=10$

6. g-h

Putting values

$=-7-3\\=-10$

Hence,

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Noah is thinking of two fractions that have the same sum of 3/5. Each fraction has a numerator of 1. What are the denimonitors o

Ray Of Light [21]

Answer:

The denominators of fractions are : 2 and 10

Step-by-step explanation:

$\text{Let the two fractions be : }\frac{1}{x}\thinspace and\thinspace \frac{1}{y}\\\\\implies \frac{1}{x}+\frac{1}{y}=\frac{3}{5}\\\\\implies 5\cdot x +5\cdot y-3\cdot x\cdot y=0$

By hit and trial method, if we put x = 2 and y = 10 then the resulting equation (1) is satisfied and all the conditions hold.

So, the denominators are 2 and 10
