The each day of the trip will cost the family $212 .
In the question ,
it is given that ,
a family is going on 3 day trip ,
the cost for hotel for 3 days is = $336 ,
So , the cost for the hotel for 1 day is = $336/3 = $112 ,
the amount budgeted for the food is one hundred dollar
the cost for the food for 1 day is = $100 .
So , the cost for each day is = cost of food + cost of hotel
Substituting the values of food and hotel ,
we get ,
= 100 + 112
Adding both the terms ,
we get ,
= 212
Therefore , the cost for each day is = $212 .

Answer:
You draw the line of the graph and every point on the line is a solution
Step-by-step explanation:
y = mx + b You graph the b which is the y intercept. This is where the graph crosses the x axis. In this case it is -12. From that point (0,-12) You follow a pattern which is the slope. In this case the slope is -3. That mans that you move three units down and then 1 unit right.

Sharon started with $42 in her bank account and
added $16 per week. Neil started out $70 in debt and deposited $30 per week. Determine how many weeks it will take them to have saved the same amount of money.
The number of weeks it will take them to have saved thesame amount is 8 weeks
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.
if x represents the the number of weeks for saving and y represents the equal saved amount, then
42+16x = y equation 1
-70+ 30x = y equation 2
subtract equation 1 from 2
-70-42+16x- 30x= 0
-112+14x= 0
collect like terms
-112=-14x
divide both sides by 14
x= -112/-14
x= 8weeks
therefore it will take them 8 weeks to have equal savings

Which graph shows a system with no solutions?
I need help with this please i don’t understand
Answer:
99
Step-by-step explanation:
Since the triangles are similar, we know the ratio of the sides is a constant. We know that SQ is 55, and the corresponding side on the other triangle is 10. This lets us find the ratio for the whole triangle! The ratio is 55/10, or 5.5.
To solve for RS, consider the corresponding side on the other triangle(LS) which is 18. We multiply that by the ratio to get 18 * 5.5 = 99, which is the length of RS.
I don't know if you need to solve for x, but if you do, here it is! We have [tex]99 = 12x+3[/tex] (the equation for side RS). subtracting 3 from both sides results in [tex]96 = 12x[/tex], and dividing by x gives us that x = 8.

the perimeter and the width of a rectangle are 64 m and 2 m, respectively. what is the area of the rectangle?
Area of the given rectangle as per given perimeter and width is equal to 60m².
As given in the question,
Perimeter of the given rectangle = 64m
Width of the given rectangle 'w' = 2m
Let us consider 'l' be the length of the rectangle
Perimeter of the rectangle = 2 ( l + w )
Substitute the values
64 = 2 ( l + 2)
⇒32 = l + 2
⇒l = 32 - 2
⇒l = 30m
Area of the given rectangle = l × w
= 30 × 2

How to write the equation of the line with m = - 3/4 that goes through (2, –5) in
Slope–Intercept Form.
Answer: y=-3/4x-3.5
Step-by-step explanation:
First, set up the equation based on the information we already know. The slope-intercept form is y=mx+b (m being the slop and b is the y-intercept)
We already know the slope, so we can substitute it.
y=-3/4x+b
Now, the only variable we need to find is b (the y-intercept)
To do this we can substitute the point that was given, (2,-5)
Substitute -5 in for y and 2 in for x.
Then you get the equation -5=-3/4(2)+b
Multiply -3/4 and 2 and you get -5=-3/2+b
Add -3/2 from both sides to isolate b
You then get b=-3.5
Substitute b back in the original equation
Your final answer is y=-3/4x-3.5
