Answer:

x = −8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(x + x) + (75 +53 + 68) = 180 (Combine Like Terms)

2x + 196 =180

Step 2: Subtract 196 from both sides.

2x + 196 − 196 = 180 −196

2x = −16

Step 3: Divide both sides by 2

x = -8

Hope this helps!!!

Katen [24]

Answer:

Jon - Andrea = 1/10
Callie - Jon = 3/10

Step-by-step explanation:

In terms of tenths, the distances each hiked are ...

Andrea — 4/10
Jon — 5/10
Callie — 8/10

Then the differences of interest are ...

Jon - Andrea = 5/10 -4/10 = 1/10

Callie - Jon = 8/10 - 5/10 = 3/10

Jon hiked 1/10 of the trail more than Andrea.

Callie hiked 3/10 of the trail more than Jon.

strojnjashka [21]

Answer:

0.0723 cubic feet < 1 cubic foot.

Step-by-step explanation:

A cube-shaped salt lick is ordered by a rancher and the length of each salt lick is $\frac{5}{12}$ foot.

Therefore, the side length of each salt lick of cube-shape is $\frac{5}{12}$ foot.

So, the volume of each salt lick is $(\frac{5}{12} \times \frac{5}{12} \times \frac{5}{12}) = \frac{125}{1728} = 0.0723$ cubic feet.

Hence, this volume is less than 1 cubic foot. (Answer)

What are the x-intercepts of y=2x^2+6x-20?

NISA [10]

Answer:

the x-intercepts are -5 and 2

Step-by-step explanation:

$y=2x^2+6x-20$

x-intercept is when y is set equal to zero

So, y = 0

$0 = 2x^2+6x-20$

$2x^3+6x-20 = 0\\Taking \ 2 \ common\\2(x^2+3x-10) = 0\\Dividing \ both \ sides \ by \ 2\\x^2+3x-10 = 0\\Using \ mid\ term \ break \ formula\\x^2+5x-2x-10 = 0\\x(x+5)-2(x+5)=0\\Taking \ (x+5) \ common\\(x+5)(x-2) = 0$

Either,

x+5 = 0 OR x-2 = 0

x = -5 OR x = 2

So, the x-intercepts are -5 and 2
