Chuck brought $40.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1 /4 as much as the souvenir, and the souvenir cost 2 /3 the cost of the pass. Chuck had $1.50 left over after buying these items.
Answer:
Souvenir = £14
Burger = £3.50
Pass = £21
Step-by-step explanation:
Souvenir = £x
Burger = [tex]\frac{1}{4}x[/tex]
Pass = [tex]\frac{3}{2}x[/tex]
[tex]\frac{1}{4}x + \frac{3}{2}x +x = 40 - 1.5[/tex]
[tex]\frac{1}{4}x+\frac{6}{4}x+x= 38.5[/tex]
[tex]\frac{11}{4}x = 38.5[/tex]
[tex]11x = 154[/tex]
[tex]x = 14[/tex]

Does anybody know this? A house casts a shadow that is 57 feet long at the same time a girl who is 4.7 feet tall casts a shadow that is 9.4 feet long how tall is the house do not round your answer
Answer:
h = 28.5 ft
Step-by-step explanation:
the 2 situations are similar, that is the triangles formed in both cases are similar.
then the ratios of corresponding sides are in proportion
let h be the height of the house , then
[tex]\frac{4.7}{h}[/tex] = [tex]\frac{9.4}{57}[/tex] ( cross- multiply )
9.4h = 4.7 × 57 = 267.9 ( divide both sides by 9.4 )
h = 28.5 ft

Determine the equation of the circle graphed below.
Using the linear combination method, find the solution to this system of equations. Be sure to show all your steps in your work!
5x+4y=-14
3x+6y=6
Answer:
[tex]x=-6; y=4[/tex]
Step-by-step explanation:
Step 0: retwite the second equation by dividing LHS and RHS by 3.
[tex]x+2y=2[/tex]
Step 1: combine them as the first minus twice the second to eliminate y
[tex]I - 2\times II : 5x+4y -2x-4y=-14-4 \rightarrow 3x=-18 \rightarrow x= -6[/tex]
Step 2a: At this point I would replace the value of x in the second equation to easily solve for y. That will give you [tex]-6+2y=2 \rightarrow y=4[/tex]. I do imagine you're required to use the same method to solve for y even if it's slower so...
Step 2b: Combine them again, taking the first minus 5 times the second to eliminate x:

What is the measure of angle A, in degrees?
===========================================================
Explanation:
Let B represent the unmarked angle on the left between angle A and the 145 degree angle.
Angle B and the 145 degree angle form a straight line of 180 degrees
B+145 = 180
B = 180-145
B = 35
Then use the fact that angles A and B form a 90 degree angle
A+B = 90
A+35 = 90
A = 90-35
A = 55

Answer:
Step-by-step explanation:
Let X be par.
Jenny made x-1 strokes
Jérôme made x+4 strokes.
So, we can use the amount of strokes made, but we have to use absolute value brackets ( | | )
