The total number of? restaurant-purchased meals that the average person will eat in a? restaurant, in a? car, or at home in a ye

zmey [24]

Answer:

The number of restaurant-purchased meals eaten in a restaurant is 75, the number eaten in a car is 33 and the number eaten at home is 55.

Step-by-step explanation:

Suppose, the number of meals eaten in a restaurant is $x$ , in a car is $y$ and at home is $z$

The total number of meals eaten in a restaurant, in a car or at home is given as 163. So, the first equation will be......

$x+y+z=163 .............................(1)$

The total number meals eaten in a car or at home exceeds the number eaten in a restaurant by 13. So, the second equation will be......

$y+z=x+13 ................................(2)$

Twenty more restaurant-purchased meals will be eaten in a restaurant than at home. So, the third equation will be......

$x= z+20..................................(3)$

First, substituting equation (2) into equation (1), we will get........

$x+(x+13)=163\\ \\ \Rightarrow 2x+13=163\\ \\ \Rightarrow 2x=163-13=150\\ \\ \Rightarrow x=\frac{150}{2}=75$

Now plugging this $x=75$ into equation (3), we will get......

$75=z+20\\ \\ \Rightarrow z=75-20= 55$

Plugging $x=75$ and $z=55$ into equation (1) .........

$75+y+55=163\\ \\ \Rightarrow y+130=163\\ \\ \Rightarrow y=163-130=33$

So, the number of restaurant-purchased meals eaten in a restaurant is 75, the number eaten in a car is 33 and the number eaten at home is 55.

Usesolve the given system of two equations in two unknowns. Check your answers.

Maksim231197 [3]

Answer:

(1,4)

x= 1

y= 4

(I checked on desmos and this is correct)

Step-by-step explanation:

I'm going to solve this by substitution

To do this we need to get a variable by istelf in any equation

We'll start with 18x-2y=10

We can add 2y and divide by 2 to get

y=9x-5

This is what y will equal for now and we can plug this in for y in the second equation

3x+16(9x-5)=67

This is rather easy to solve

147x-80=67

147x=147

this means that x=1

We can then use this value for x and plug it into any equation

let's just do the first one

18*1-2y=10

This is easy to solve as well and you should get

-2y=-8

y=4

this means that x=1

y=4

The equation y = 65.18x+21.43 fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9874. Ho

pashok25 [27]

Given:

There is an equation given as

$y=65.18x+21.43$

fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9874.

Required:

We need to find that what will be worth at x= 32 days?

Explanation:

The equation fits the scatter plot of the values for stock ABC over past month with r-value of 0.9874 is

$y=65.18x+21.43$

to find ABC will be worth at x=32 just substitute x=32 in the given equation

$y=65.18(32)+21.43=2058.76+21.43=2107.19$

Final answer:

Therefore, $2107.19 ABC will be worth at x=32 days

Add 6 to both sides
2x-6+6=4+6
Simplify 4+6 to 10
2x=10
Divide both sides by 2
2x/2=10/2
Simplify 10/2
x=5
