Alicia purchased H half-gallons of ice cream for $3.50 each and P packages of ice cream cones for
$2.50 each. She purchased 14 items and spent $43. Which system of equations could be used to
determine how many of each item Alicia purchased?
(1) 3.50H + 2.50P = 43 (3) 3.50H + 2.50P = 14
H+P = 14
H+ P = 43
(2) 3.50P+2.50H = 43
P+ H = 14
(4) 3.50P + 2.50H = 14
P+H = 43

Step-by-step explanation:

Answer:

Step-by-step explanation:

General Point Slope Form is:

We are given the slope of (5/4) and the point of (8, -2).

Replace the variables with their appropriate values:

[tex]x_1 \rightarrow8\\\\y_1\rightarrow-2\\\\m\rightarrow\frac{5}{4}\\\\\text{Replace } x_1, y_1, \text{and } m \text{ with the appropriate values.}\\\\y-y_1=m(x-x_1)\rightarrow y-(-2)=\frac{5}{4}(x-8)\\\\\text{Simplify:}\\\\y-(-2)=\frac{5}{4}(x-8)\rightarrow y+2=\frac{5}{4}(x-8)\\\\\\\text{Our final answer is:}\\\\ \huge\boxed{y+2=\frac{5}{4}(x-8)}[/tex]

3х + 1 = 10
solve equation ​

Answers

Answer:

x = 3

Step-by-step explanation:

3x + 1 = 10

Combine the constants by subtracting 1 from both sides.

3x = 9

Isolate the variable by dividing both sides by 3.

x = 3

Check.

3(3) + 1 = 10

9 + 1 = 10

10 = 10

Your answer is correct.

Hope this helps!

Answer:

  x = 3

Step-by-step explanation:

3x + 1 = 10

      - 1 = - 1

---------------  ( subtract 1 on both sides )

    3x = 9

    3x = 3

---------------  ( divide by 3 on both sides )

     x = 3

now you're left with x = 3 which is your answer! hope this helps. ^_^

A student walks at a rate of 1.5 meters per second for 4 seconds and then stops for 4 seconds. Then the student
continues walking at the original rate.
Which graph best represents the student's walk?

Answers

Answer:

A

Step-by-step explanation:

I finished the question and got it right

Graph is a way to represent a lot of data in a visual formal. The graph that best represents the student's walk is graph A.

What is a graph?

A graph is a way to represent a lot of data in such a visual formal that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

As we can see that the y-axis of the graph represents the distance traveled by the student while, the time taken by the student to cover the distance is given on the x-axis.

We know that the rate of 1.5 meters per second, means that the student will cover the 1.5 meters in 1 second, therefore, the line will be a slope that will represent the walk of the student. At time t=4 seconds, a student stopped for 4 seconds therefore, the time will increase but the distance will be constant for the student, therefore, the situation will be represented by a horizontal line.

Hence, the graph that best represents the student's walk is graph A.

Given:-

HM = 2x+5 FM = X+8 HF = 3x+2 perimeter (∆HFM) = 51 units

To find:-

whether ∆ HFM is congruent to ∆FMK

Solution:-

:[tex]\implies[/tex] perimeter (∆HFM) = HM+FM+HF

:[tex]\implies[/tex] 51 = 2x+5+x+8+3x+2

:[tex]\implies[/tex] 51 = 6x+15

:[tex]\implies[/tex] 36 = 6x

:[tex]\implies[/tex] x = 6 units.

in ∆HFM,

HM = 2x+5 = 2(6)+5 = 12+5 = 17units FM = X+8 = 6+8 = 14 units HF = 3x+2 = 3(6)+2 = 20 units

in ∆KFM,

FM = 14 units KF = 4x-3 = 4(6)-3 = 21 units MK = 3x-1 = 3(6)-1 = 17 units

Since, all the sides of one triangle does not correspond to the other, these traingles are not congruent.
