-6.3x+14 and 1.5x-6<br> answer in simplified form
koban [17]

Answer:

The simplified form of -6.3x+14 and 1.5x-6 is -4.8x+8

Step-by-step explanation:

We have to simplify the following

-6.3x+14 and 1.5x-6

it can be written as:

=(-6.3x+14) + (1.5x-6)

Adding the like terms

=(-6.3x+1.5x)+(14-6)

= (-4.8x)+(8)

= -4.8x+8

So, the simplified form of -6.3x+14 and 1.5x-6 is -4.8x+8

Two sides of a triangle are equal in length and double the length of the shortest side. The perimeter of the triangle is 36 inch
chubhunter [2.5K]

Answer:

Two equal sides = 14.4 inches each

Shortest side = 7.2 inches

Step-by-step explanation:

a + b + c = 36

a = b

a = 2c

then:

c = a/2

a + a + a/2 = 36

2a + a/2 = 36

4a/2 + a/2 = 36

5a/2 = 36

a = 2*36/5

a = 72/5

a = 14.4

a = 2c

14.4 = 2*c

c = 14.4/2

c = 7.2

a = b

b = 14.4

Check:

14.4 + 14.4 + 7.2 = 36

HELP ASAP!! GIVING 20 POINTS AND BRAINLIEST!!! Solve for x. y=7x-7z-9
svetlana [45]
We just need to see everything that is not x as a number.

if I asked
5 = 7x - 7(2) - 9
we would solve it by combining like terms first. but, if I tell you not to do that, we would add 9 and 7(2) to both side and end up with
5 + 7(2) + 9 = 7x
we would then divide both sides by 7
\frac{5 + 7(2)  + 9}{7}  = x

math is always math... it's just how we look at it. so, do the same steps!
y = 7x - 7z - 9
add 9 and 7z to both side
y + 7z + 9 = 7x
divide both sides by 7
\frac{y + 7z + 9}{7}  = x
