x = 10
3х + 1 = 10
solve equation
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. ^_^

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
Answer:
3.50H + 2.50P = 43

Use quadrilateral ABCD. What value for m DAB would show ABCD is a parallelogram?
Answer:
m∠DAB = 101°
x = 7
y = 12
Step-by-step explanation:
Properties of a parallelogram,
1). Opposite sides of a parallelogram are equal and parallel.
2). Opposite interior angles are equal in measure.
3). Consecutive interior angles are supplementary.
By the first property,
BC ≅ AD
2x + 4 = 3x - 3
3x - 2x = 4 + 3
x = 7
AB ≅ CD
2y + 10 = 3y - 2
3y - 2y = 10 + 2
y = 12
By second property,
m∠ABC = m∠ADC
2z + 15 = 3z - 17
3z - 2z = 15 + 17
z = 32
Therefore, m∠ADC = (3z - 17)°
= 3(32) - 17
= 96 - 17
= 79°
By third property,
m∠ADC + m∠DAB = 180°
79° + m∠DAB = 180°
m∠DAB = 180° - 79°
m∠DAB = 101°
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?
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.

A line passes through the point (8, -2) and has a slope of 5/4. Write an Equation in point-slope form for this line
Answer:
y=5/4x-8
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
General Point Slope Form is:
[tex]y-y_1=m(x-x_1)\\\\\rightarrow \text{m - slope}\\\\\rightarrow (x_1,y_1)\text{ - given point}[/tex]
We are given the slope of (5/4) and the point of (8, -2).
Replace the variables with their appropriate values:
