If 16 is added to one-third of a number, the result is three times the number. What is the number?

1 answer:

4 0

First set up the equation based on the description.

$\frac{1}{3}$ x + 16 = 3x

Use subtraction to get the "x"s on one side of the equation. You can next subtract $\frac{1}{3}$ x from both sides.

16 = $\frac{8}{3}$ x

Now you can multiply both sides of the equation by $\frac{3}{8}$ to solve for x

x = 6

Which lines are parallel to 8x + 2y = 7?

Ede4ka [16]

Answer:

8x + 2y = 7

2y = -8x + 7

y = -4x + 7/2; this line has slope equal -4

Parallel lines, slope is the same so slope of parallel line is also -4

A. y − 1 = 4(x + 8); slope m = 4....FALSE

B. y = −4x + 15; slope m = - 4....TRUE

C. 16x + 4y = 9; 4y = -16x + 9 so y = -4x + 9/4; slope m = - 4....TRUE

D. y = −4x; slope m = - 4....TRUE

Mana is saving to buy a new bicycle. The equation d = 12w represents the amount in dollars, d, that Mana saves in w weeks.What i

Alchen [17]

Answer:

Constant of proportionality is 12

The cost of buying new bicycle changes 12 dollar per week

Step-by-step explanation:

we are given

The equation as

$d=12w$

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

$y=kx$

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

$12=\frac{d}{w}$

So,

The cost of buying new bicycle changes 12 dollar per week
