Cx-4=7

add 4 on both sides

cx=11

divide c on both sides

$x = \frac{11}{c}$

Answer:

$x=\frac{11}{c}$

Step-by-step explanation:

We have been given the equation $cx-4=7$

We have to eliminate 4 from the left hand side of the equation. Since, 4 is in subtraction hence, add 4 to both sides to eliminate 4.

$cx-4+4=7+4\\\\cx=11$

Now, we have to eliminate c. Since, c is in multiplication with x hence, divide both sides by c

$\frac{cx}{c}=\frac{11}{c}\\\\x=\frac{11}{c}$

Therefore, the value of x is $x=\frac{11}{c}$

ad-work [718]

Answer:

The salary after four consecutive increase = $ 46794.34

Step-by-step explanation:

According to question,

salary of MR. John = $ 40000 per year

percentage py increase = 4%

Let the salary after four consecutive pay increase = x

So, X = 40000 (1 + $\frac{4}{100}$ )^4

Or, X = 40000 ( $\frac{26}{25}$ )^4

Or, X = 46794.34

Hence the salary increase after four consecutive pay increase at 4% = $46794.34 Answer

Could 1.5, 2.5, 3.5 and 6, 10, 12 be the corresponding sides of two similar triangles

boyakko [2]

Answer:

Step-by-step explanation:

If the ratios of the corresponding sides are equal then they would be the sides of 2 similar triangles.

Calculate the ratio of corresponding sides.

$\frac{6}{1.5}$ = 4

$\frac{10}{2.5}$ = 4

$\frac{12}{3.5}$ ≠ 4

Thus the sides are not the corresponding sides of similar triangles.

Given that

timofeeve [1]

Answer:

Step-by-step explanation:

(sec α - tan α)(sec α + tan α) = sec^2 α - tan^2α

But sec^2 α = 1 + tan^2 α so

sec^2 α - tan^2α = 1 + tan^2 α - tan^2α

= 1

so 1 = (sec α - tan α)(sec α + tan α) = 1/4 * x where x is sec α + tan α

1/4 * x = 1

x = 4.

The perimeter of a rectangle is 40 cm. The length is 14 cm. Let x = width of the rectangle. Ravi says he can find the width usin

Usimov [2.4K]

Answer:

Divide both sides by 2

Step-by-step explanation:

We have the equation

2(x + 14) = 40

We divide both sides by 2

2(x + 14) = 40/2

x + 14 = 20

x = 20 - 14

x = 6

Therefore, the most helpful first step for solving Ravi's equation is: Divide both sides by 2
