(Variables on both sides of an equation)

2 answers:

7 0

Start by expanding the left side of the equation: -2(4x-7) is equal to -8x + 14.

This brings you to -8x+14 = -8x + 14.

Now add 8x to both sides. This brings you to 14 = 14

Now subtract 14 from both sides. This brings you to 0 = 0.

Thus your answer is 0 = 0, which is a true statement.

Hope this helps.

-8x + 14 = -2(4x - 7)
Open parenthesis and distribute
-8x + 14 = -8x + 14
Subtract both sides by 14
-8x = -8x
Subtract both sides by -8x
0=0
Thus, any value of x will satisfy the equation.

When Vince does 14 push-ups and 12 sit-ups, it takes a total of 52 seconds. In comparison, he needs 48 seconds to do 12 push-ups

marshall27 [118]

Answer:

it takes 2 seconds to do one situp

it takes 2 seconds to do one pushup

to do 14 pushups, it takes 28 seconds.

to do 12 situps it takes 24 seconds

to do 12 pushups, it takes 24 seconds

BRAINLIEST PLEASE!

hope this helps :)

Step-by-step explanation:

14x + 12y = 52

12x + 12y = 48

^^^ this is an inequality that we can make.

x stands for pushups

y stands for situps

if we subtract the second equation from the first, we get

2x = 4

x = 2

now we can place x in one of the equations to solve for y

12(2)+12y=48

24 + 12y = 48

12y = 24

y = 2

Find the surface area of the sphere with the given dimension. Leave your answer in terms of π. Sphere with radius of 60 m.

prohojiy [21]

The surface area of a sphere is given by $A=4 \pi r^{2}$ where r represents the radius.

As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.

$A=4 \pi ( 60^{2} )=14400 \pi$
