Spiral Review A chili cook-off has adult tickets a and child tickets C. A group of visitors buys 3 adult tickets and 2 child tickets and pays a total of $26.
Another group buys 5 adult tickets and 3 child tickets and pays $42. Write and solve a system of equations to find the price of each type of ticket.
Enter the correct answers in the boxes.
Equation 1:?
Equation 2:?
adult: $ 6
child: $ 4
I just need help on making equations
Equation 1 would be: 3a+2C
Equation 2 would be: 5a+3C
The system of equations are solved and the cost of adult ticket and child tickets are $ 6 and $ 4 respectively
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the adult tickets be a
Let the child tickets be c
Group A buys 3 adult tickets and 2 child tickets and pays a total of $26
So , 3a + 2c = 26 be equation (1)
And , Group B buys 5 adult tickets and 3 child tickets and pays $42
So , 5a + 3c = 42 be equation (2)
On simplifying , we get
Multiply equation (1) by 5 and equation (2) by 3 , we get
15a + 10c = 130 be equation (3)
15a + 9c = 126 be equation (4)
Subtracting equation (4) from equation (3) , we get
c = $ 4
Therefore , the cost of child ticket is $ 4
Substituting the value of c in equation (1) , we get
3a + 2 ( 4 ) = 26
3a + 8 = 26
Subtracting 8 on both sides , we get
3a = 18
Divide by 3 on both sides , we get
a = $ 6
Therefore , the cost of adult ticket is $ 6
Hence , the system of equations are solved

Mr. Tyssee got a haircut, which cost $35. He gave the
stylist a 15% tip. How much will he pay for the haricut
including tip?
Answer:
$40.25
Step-by-step explanation:
15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.
Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25
HI SOMEONE PLEASE HELP I HAVE NO IDEA HOW TO DO THIS :(( i need to know the measure of angles 13 and 12 then the measure of the line segment SG. Thank you sm in advance
Answer:
Angle 13 equal 90 and Angle 12 equal 45
Step-by-step explanation:
This is a square so all of the corner angles and the diagonals angles measure 90 degrees. A square also forms 4 congruent isoceles triangles or technically 45-45-90 triangles. So that means the following angles measure 45 degrees since they share a point
Angle 5,6,7,8,9,10,11,12. So the measure of 12 is 90 degrees.
To find the measure of 13, in a square diagonals bisect each other and form perpendicular lines so that means every angle in the middle of the square measure 90 degrees.
Using that
Angle 13,15,16 and R measure 90 degrees so Angle 13 equal 90.

Answer:
[tex]c = 41[/tex]
Step-by-step explanation:
[tex] {c}^{2} = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
[tex]c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
[tex]c = \sqrt{ {9}^{2} + {40}^{2} } [/tex]

At a construction job for a mansion there are 32 painters. Of these painters, 24 of them are painting the interior of the mansion. What percent of these painters are painting the interior?
Answer:
[tex]\% Percent = 75 \%[/tex]
Step-by-step explanation:
Given
[tex]Painters = 32[/tex]
[tex]Interior\ Painters = 24[/tex]
Required
Determine the percentage of the interior painters
This percentage is calculated as:
[tex]\% Percent = \frac{Interior\ Painters}{Painters} * 100\%[/tex]
This gives:
[tex]\% Percent = \frac{24}{32} * 100\%[/tex]
[tex]\% Percent = \frac{24* 100\%}{32}[/tex]
[tex]\% Percent = \frac{2400\%}{32}[/tex]
[tex]\% Percent = 75 \%[/tex]
75% are painting the interiors

Answer:
4x-y=19, y=4x-19
Step-by-step explanation:
I learned a really quick way to do these in geometry.
Let's use standard form or ax+by=c.
Slope of 4: 4x - y = c.
Passes through point 6,5.
4(6) - 5 = c
c= 24-5
c=19

Find the slope and the y-intercept of the graph of the linear equation. 1. y=3x-7 2. y-1=-2/3x
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
