Three consecutive integers can be represented by n, n + 1, and n + 2. if the seum of three consecutive integers is 57, what are

Helen [10]

Sum means add
sum of the 3 is
n+n+1+n+2

it add to 57
n+n+1+n+2=57
3n+3=57
minus 3 both sides
3n=54
divide both sides by 3
n=15
n+1=16
n+2=17

the integers are 15,16, and 17

Answer:

See Explanation

Step-by-step explanation:

Required

Expression for area of triangle

This is calculated using

$Area = \frac{1}{2} * base * height$

Assume that:

$base = 5cm; height = 2cm$

The equation becomes

$Area = \frac{1}{2} * 5* 2$

I really need help quick

Natali [406]

Answer:

$\sf x=2+\sqrt{6},\:x=2-\sqrt{6}$

Explanation:

$\sf y = x^2 -4x$

given that y = 2

$\sf x^2 -4x = 2$

$\sf x^2 -4x -2 = 0$

using quadratic formula:

$\sf x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \ \ \ when \ ax^2 + bx + c = 0$

$\rightarrow \sf x_{1,\:2}=\dfrac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4\cdot \:1\cdot \left(-2\right)}}{2\cdot \:1}$

$\rightarrow \sf x_1=\dfrac{-\left(-4\right)+2\sqrt{6}}{2\cdot \:1},\:x_2=\dfrac{-\left(-4\right)-2\sqrt{6}}{2\cdot \:1}$

$\rightarrow \sf x=2+\sqrt{6},\:x=2-\sqrt{6}$

in decimals:

$\rightarrow \sf x=4.45 , \ -0.45$

Please answer ASAP, I’m really struggling. Percents applications. Mark as brainlest! Write an equation for each problem. Then so

GalinKa [24]

You would leave $30.24 as the tip.

That's a LOT!

The total amount being paid is $178.08.

A total of a $10.08 tax!

You would have spent a total of $208.32.

Yikes!

Hope this helped! If it didn't, please tell me so I can fix it!
