Answer 2

Answer:

Answer:

First result: X = 248/3 or 82.67 Second result: X = 260/3 or 86.57

Step-by-step explanation:

1st one: 7x + 8(x + 1/4) = 3(6x - 90 - 8)

7x + 8x + 2 = 18x - 270 - 24

15x + 2 - 2 = 18x - 246 - 2

15x - 18x = 18x - 18x -248

-3x = 248 --> -3x/3 = 248/3

X = 248/3 or X = 82.67

2nd one: 7x + 8(x+1/4) = 3(6x - 90) - 8

7x + 8x + 2 = 18x - 270 - 8

15x + 2 - 2 = 18x - 262 - 2

15x - 18x = 18x -18x - 260

-3x = 260 --> -3x/3 = 260/3

X = 260/3 or X = 86.67

Sorry if none of these are the answer!

Eight cakes cost 4.00. how much do three cakes cost ?

Answers

8 cakes ... 4.00
3 cakes ... x = ?

If you would like to know how much do 3 cakes cost, you can calculate this using the following steps:

8 * x = 4 * 3
8 * x = 12 /8
x = 12/8
x = 3/2 = 1.5

The correct result would be 1.5.

three cakes equals $1.50
because.....
8 divided by $4.00 equals 2
so 3 divided by 2 equals $1.50

On a coordinate grid, point A is at (−3.0, −5.4) and point B is at (−3.0, 5.4). Point B is a reflection of point A across the ___–axis. Input either a lowercase x or y.

Answers

Given:
Point A (-3.0,-5.4)
Point B (-3.0,5.4)

reflection across y-axis ⇒ (a,b) reflected (-a,b)
reflection across x-axis ⇒ (a,b) reflected (a,-b)
reflection across the origin ⇒ (a,b) reflected (-a,-b)
reflection on y = x ⇒ (a,b) reflected (b,a)

Point B is a reflection of Point A across the x-axis.

Answer:

X- axis
