The total cost of 3 bags of chips and 4 jars of salsa at a
store is $11.25. The cost of each bag of chips is $2.75.
Write an equation that can be used to determine the cost
,
X, of 1 jar of salsa.
Answer: 2.75(3) + 4x = 11.25
Step-by-step explanation:
It says each bag costs $2.75 and there are 3 bags so multiply those 2 and then subtract them from the total cost (11). What you get after you subtract is the total costs of the salsa so divide that by 4 to get the cost of each, in this case it doesn't ask so we leave it as 4x.

Find the value of x if A, B, and C are collinear points and B is between A and C. AB=6x,BC=x−5,AC=23
Answer:
The value of x = 4 if A, B, and C are collinear points and B is between A and C.
Step-by-step explanation:
We need to find the value of x if A, B, and C are collinear points and B is between A and C.
We have AB=6x,BC=x−5,AC=23
If points are collinear and B is between A and C we can write:
AC=AB+BC
Putting values and finding value of x
[tex]AC = AB+BC\\23=6x+x-5\\23=7x-5\\7x=23+5\\7x=28\\x=\frac{28}{7}\\x=4[/tex]
The value of x = 4 if A, B, and C are collinear points and B is between A and C.

Answer:
15
Step-by-step explanation:
The amount of water displacement would be equivalent to the volume of the rock, which is 1800. We find this by doing 10 x 12 which is 120. Now we can divide 1800 by 120, which is 15. Giving us the dimensions 10 x 12 x 15.
Mr. Jones charged Roberta $32 for parts and $15 per hour for labor to repair her bicycle. He spent 3 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
Answer:
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones

write the algebraic expression for: The length of a rectangle is 3 feet less than 4 times its width.
Answer:
Perimeter (P) is: 48
Problem to solve:
48=2(2x+3)+2(x)

48=6x+6
48-6=6x+6-6

Devin in travel from Florida to New Jersey by car. The car traveled 800 miles in 12 hours. Find the speed in feet per minute. Show the correct work and correct answer. Round to the nearest hundredth.
Answer:
Step-by-step explanation:
Step 1: Simplify
[tex]800m/12h = 66\frac{2}{3}m/h[/tex] (66 2/3 miles per hour)
Step 2: Transform hours into minutes by dividing by 60
[tex]66\frac{2}{3}m/h / 60\\[/tex]
[tex]1\frac{1}{9} m/m[/tex] (1 1/9 miles per minute)
Step 3: Transform miles into feet by multiplying by 5280
[tex]1\frac{1}{9}*5280[/tex]
[tex]5866\frac{2}{3}f/m\\\\[/tex]
or [tex]5866.667f/m[/tex] (feet per minute)

Find the value of each variable in the parallelogram.
Answer:
u = 4; v = 18
because this is a parallelogram
=> 2u + 2 = 5u - 10
6 = v/3
<=> 3u = 12
v = 6.3
<=> u = 4
v = 18
What is the value of z?
Answer:
68°
Step-by-step explanation:
Every figure must sum 180°(Sides-2) degrees
Example: For a triangle (3 sides) 180°(3-2) => 180°(1) =>180°
In this case: 5 sides 180°(5-2) => 540°
So all the angles (5) must sum 540°
Mathematically expressed as:
[tex](119)+(z)+(2z)+(70)+(2z)+(11)=540\\119+z+2z+70+2z+11=540\\200+5z=540\\5z=540-200\\5z=340\\z=\frac{340}{5}\\z=68'[/tex]
Lets see changing every Z by 68...
119+68+2(68)+70+2(68)+11
119+68+136+70+136+11=540°

An educational psychologist wishes to know the mean number of words a third grader can read per minute. She wants to make an estimate at the 85% level of confidence. For a sample of 295 third graders, the mean words per minute read was 26.9. Assume a population standard deviation of 2.7. Construct the confidence interval for the mean number of words a third grader can read per minute. Round your answers to one decimal place
Answer:
85% level of the confidence interval is
(26.337, 26.662)
Step-by-step explanation:
Explanation:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by
[tex](x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })[/tex]
Critical value Z₀.₁₅ = 1.036
85% level of the confidence interval is determined by
[tex](x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })[/tex]
[tex](26.9 -1.036 \frac{2.7}{\sqrt{295} } , 26.5 + 1.036 \frac{2.7}{\sqrt{295} })[/tex]
