If 6:2=8:x, then<br><br> a. 6x = 16<br> b. 6x = 10<br> c. 2x = 48<br> d. 2x = 14

stellarik [79]

Answer:

6x = 16

Step-by-step explanation:

Given:

$\displaystyle \large{6:2 = 8:x}$

The equation can be rewritten as:

$\displaystyle \large{\dfrac{6}{2}=\dfrac{8}{x}}$

Multiply both sides by 2x.

$\displaystyle \large{\dfrac{6}{2}\cdot 2x=\dfrac{8}{x}\cdot 2x}$

Simplify the equation in simplest form.

$\displaystyle \large{6x=8\cdot 2}\\\\\displaystyle \large{6x=16}$

Therefore, the answer to this question is 6x = 16.

The width of Estelle's rectangular living room is 4 meters, and the distance between opposite corners is 7 meters. What is the l

Crank

Answer:

5.7 meters

Step-by-step explanation:

Image a rectangle being cut diagonally in half, that would lead to two triangles. We can use the pythagorean theorem to find the missing side.

7 is the hypotenuse and 4 is the side length

4^2+x^2=7^2

16+x^2=49

sqrx=sqr(49-16)

x=sqr33

x=5.74

Rounded to the nearest tenth is 5.7

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% sa

Vinvika [58]

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

$C_{i}V_{i}=C_{f}V_{f}$

Where:

C(i) is the initial concentration of the solution (80%)
C(f) is the final concentration of the solution (30%)
V(i) is the initial volume (150 ml)
V(f) is the final volume

Now, we just need to solve the equation for V(f).

$V_{f}=\frac{C_{i}V_{i}}{C_{f}}$

$V_{f}=\frac{80*150}{30}$

$V_{f}=400\: ml$

Therefore, we must add 400 ml of water.

I hope it helps you!

Alika [10]

Answer:

One triangle

Step-by-step explanation:

-The triangle's dimensions are defined and fixed.

-Given the fixed dimensions, only one unique triangle can be constructed.

-Hence, only one triangle of the dimensions 7.2cm, 6.9cm and 12.8 cm can be formed.
