A restaurant earns $1073 on Friday and $1108 on Saturday. Write and solve an equation to find the amount xx (in dollars) the res

julia-pushkina [17]

Money earned by restaurant on Friday=$1073

Money earned by restaurant on Saturday=$1108

Let Money earned by restaurant on Sunday=$x

Average=$1000

$\text { average}=\frac { sum of all the observation}{total number of observation}$

Number of observation=3

⇒ 3× 1000=1073+1108+x

⇒3000= 2 181+x

⇒3000-2181=x

⇒x=819

The restaurant needs to earn on Sunday to average $1000 per day over the three-day period=$819

System of Equations <br> Need help<br> Trig

Yanka [14]

Looks like the system is

$\begin{cases}-2x+y+6z=1\\3x+2y+5z=16\\7x+3y-4z=11\end{cases}$

We can eliminate $y$ by taking

$(3x+2y+5z)-2(-2x+y+6z)=16-2(1)$

$\implies3x+2y+5z+4x-2y-12z=16-2$

$\implies7x-7z=14$

$\implies x-z=2$

so that $z=x-2$ , and

$(7x+3y-4z)-3(-2x+y+6z)=11-3(1)$

$\implies7x+3y-4z+6x-3y-18z=11-3$

$\implies13x-22z=8$

Substitute $z=x-2$ into this last equation and solve for $x$ :

$13x-22(x-2)=8$

$\implies13x-22x+44=8$

$\implies-9x=-36$

$\implies x=4$

Then

$z=x-2$

$\implies z=4-2$

$\implies z=2$

Plug these values into any one of the original equation to solve for $y$ :

$-2x+y+6z=1$

$\implies-2(4)+y+6(2)=1$

$\implies-8+y+12=1$

$\implies y=-3$

Hence the solution is x = 4, y = -3, and z = 2.

Pls I need help with this question..Thanks

Nimfa-mama [501]

Answer:

60cm

Step-by-step explanation:

1:50 means every foot is 50 feet.

So I would think the ship hes making will be 2 feet long.

Every foot is equal to 0.3m which is equal to 30cm

Every foot is equal to 30cm

2 x 30cm = 60cm

Five less than two times a number is sixty-nine. A. 5 – 2t = 69 t = –32 B. 2t – 5 = 69 t = 37 C. 5 + 2t = 69 t = 32 D. none of t

Julli [10]

Let's translate the expression step by step:

"Five less than..." $\to$ we will have to subtract five from something

"two times a number" $\to 2t$ .

So, we have

"Five less than two times a number" $\to 2t-5$ .

This "is sixty-nine", where "is" means "is equal to". So, the equation is

$2t-5=69$

which is option B
