x=17
Answer:
17
Step-by-step explanation:
7x + 15° = 4x + 66° (vertically opposite angles are equal)
7x - 4x = 66 - 15
3x = 51
x = 51/3
x = 17

How many 2 3 -quart portions are in 7 1 2 quarts of soup?
Answers
Answer:
[tex]Number = 11\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Soup = 7\frac{1}{2}[/tex] quarts
[tex]Portion = \frac{2}{3}[/tex] quarts
Required
Determine the number of portions in the soup
The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion
[tex]Number = Soup/Portion[/tex]
Substitute values for Soup and Portion
[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]
[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]
Convert mixed fraction to improper fraction
[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]
[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]
[tex]Number = \frac{15*3}{2*2}[/tex]
[tex]Number = \frac{45}{4}[/tex]
[tex]Number = 11\frac{1}{4}[/tex]
Hence, there are [tex]11\frac{1}{4}[/tex] of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup

Samantha has $300 for guitar lessons to learn her favorite song. Mrs. Jones charges $80 per lesson and requires three lessons to teach Samantha the song. Mr. Beliz charges $62 per lesson and requires four lessons to teach Samantha the song. Use integers to represent what each teacher charges. Which is the better deal for Samantha?
Answers
Answer:
Mrs. Jones has the better deal
Step-by-step explanation:
Samantha has $300
Mrs. Jones charges $80 per lesson and she requires three so we do 80* 3 (the lessons) which equals 240
Mrs. Beliz charges $62 per lesson and requires 4 lessons so we do 62*4 (the lessons) which equals 248
240<240 (so Mrs. Jones has the better deal, she wants less money)

Mrs. Jones

Write the slope-intercept form of an equation for the line that passes through (2, 3) and is parallel to the graph of y = 2x -1
Answers
Answer:
ok
Step-by-step explanation:
Answer:
y = 2x -1
Step-by-step explanation:
when a two lines are parallel to each other that means they have the same slope.
you use point slope formula to find a line with the same slope and passes through (2,3)
y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get
y - 3 = 2(x -2)
first your distribute the 2 into the parenthesis and you get
y-3 = 2x -4
now add 3 to both sides
y = 2x -1

There is 2145.52 cubic inches of air in the ball
Step-by-step explanation:
A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.
Given
Radius = r = 8 in
The volume of sphere is given by:
[tex]V = \frac{4}{3} \pi r^3[/tex]
Putting the values we get
[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]
Hence,
There is 2145.52 cubic inches of air in the ball

Solving systems of equations using substitution/eliminationSolving systems of equations using graphingStep-by-step explanation:
Step 1: Define systems
3x + y = 2
4x + 3y = 3
Step 2: Rewrite systems
y = 2 - 3x
4x + 3y = 3
Step 3: Solve for x
Substitute in y: 4x + 3(2 - 3x) = 3Distribute 3: 4x + 6 - 9x = 3Combine like terms: -5x + 6 = 3Isolate x term: -5x = -3Isolate x: x = 3/5Step 4: Solve for y
Define original equation: 3x + y = 2Substitute in x: 3(3/5) + y = 2Multiply: 9/5 + y = 2Isolate y: y = 1/5Step 5: Check
Graph the systems of equations.
Answer:
x = 3/5, y = 1/5
Step-by-step explanation:
Starting with:
3x + y = 2
4x + 3y = 3
Multiplying the first equation by -3:
-9x - 3y = -6
4x + 3y = 3
Adding the equations:
-5x = -3
Simplifying:
x = 3/5
Substituting x = 3/5 into the first equation:
9/5 + y = 2
Subtracting:
y = 1/5
