Answer: 26

Step-by-step explanation:

Let the number be n.

Now,

twice a number =>> 2n

added to 3 =>> 2n + 3

is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3

(2n + 3) = (5 / 3) × (n + 7)

3 × (2n + 3) = 5 × (n + 7)

6n+9 = 5n + 35

6n - 5n = 35 - 9

n = 26

Are 3:5and 1:2 equivalent

german

Answer:

No. They are not equivalent.

Step-by-step explanation:

$\frac{3}{5} \neq \frac{1}{2}$

=> $\frac{6}{10} \neq \frac{5}{10}$

Therefore, 3/5 and 1/2 are not equivalent.

WILL MARK U AS BRAINLIEST PLEASE HELP

Answer:

782.5inch³

Step-by-step explanation:

The question is on volume of a prism and that of a cylinder

Finding the volume of the prism

V=Bh where B is the base area and h is the height

Base area=14"×14"=196 inch²

height =8"

v=196×8= 1568 in³

Finding volume of the cylinder

v=r²h where r is the radius of cylinder and h is the height of cylinder

r=10/2=5 inches and h=10 inches

v=3.142×5×5×10=785.5inch³

The difference in volume

Difference in volume=1568-785.5=782.5in

Correct answer gets Brainliest! Solve for x.

Simora [160]

Subtract 13 from both sides:

$-7-13 \geq -5x$

$-20 \geq -5x$

Divide both sides by -5. Since this is a negative number, you have to invert the inequality sign:

$4 \leq x$

Which means

$x \geq 4$
