Ralph and Jody go to the shop to buy potato chips and candy bars.
Ralph buys 3 bags of potato chips and 4 candy bars. He spends
Jody buys 4 bags of potato chips and 2 candy bars. She spends $3.00.
Later Clancy joins Ralph and Jody and asks to buy one bag of potato chips and one candy bar from
them. They need to work out how much he should pay.
Ralph writes
3p+ 4b = 375
1. If p stands for the cost, in cents, of a bag of potato chips and b stands for the cost, in cents, of a
candy bar, what does the 375 in Ralph's equation mean?
Answers
Answer:
375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars
Bag of potato = 45 cent
Candy = 60 cents
Step-by-step explanation:
375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars
3p + 4b = 375 - - (1)
4p + 2b = 300 ---(2)
From (2)
4p = 300 - 2b
p = 75 - 0.5b
Put b = 75 - 0.5b
3(75 - 0.5b) + 4b = 375
225 - 1.5b + 4b = 375
225 + 2.5b = 375
2.5b = 375 - 225
2.5b = 150
b = 150 / 2.5
b = 60
3p + 4(60) = 375
3p + 240 = 375
3p = 375 - 240
3p = 135
p = 45
Bag of potato = 45 cent
Candy = 60 cents

Answer:

Step-by-step explanation:
MATHEMATICS
vowels in mathematics = (A, E, I)
letters in mathematics = (M, A, T, H, E, I, C, S)
Probability = required outcome / Total possible outcomes
Required outcome = vowels in mathematics = 3
Total possible outcomes = letters in mathematics = 8
Probability of drawing a vowel letter tiles = 3/8
2.)
Spinner division :
Red = 4 ; white =2 ; green = 1 ; blue = 1

Probability (landing on blue) = number of blue / total
P(landing on blue) = 1 / 8
P(landing on white) = 2/ 8 = 1/4
P(landing on blue or white) = 1/8 + 2/8 = 3/8
Tell how many solutions each one has
Answers
Answer:
Step-by-step explanation:
1) 3(x + 2 ) +4 = 31
3*x + 2*3 + 4 = 31
3x + 6 + 4 = 31
3x + 10 = 31 {Subtract 10 from both sides}
3x = 31 - 10
3x = 21 {divide both sides by 3}
x = 21/3
x = 7
This equation has one solution
2) 3x + 1 = 3x + 9
Subtract 3x form both sides
3x + 1 -3x = 3x + 9 - 3x
1 ≠ 9
There is no solution for this equation.
3) 2x - 4 = 2x -4

Applying the inscribed angle theorem, the missing angles are:
m∠RUS = 65°m∠UST = 15°What is the Inscribed Angles Theorem?Based on the inscribed angle theorem, we have the following relationships:
Inscribed angle = 1/2(measure of intercepted arc)Central angle = measure of intercepted arc.Given the following:
m(RU) = 50°m(UT) = 30°Find m(RS):
m(RS) = 180 - m(RU)
Substitute
m(RS) = 180 - 50
m(RS) = 130°
Find m∠RUS:
m∠RUS = 1/2(m(RS) [inscribed angle theorem]
Substitute
m∠RUS = 1/2(130)
m∠RUS = 65°
Find m∠UST:
m∠UST = 1/2(m(UT))
Substitute
m∠UST = 1/2(30)
m∠UST = 15°

How to find the point of intersections on these equations? (x+6)^2 =-12 (y+2) x^2/81 + y^2/100 =1
Answers
Answer:
Graphically.
Step-by-step explanation:
We have the equations:
(x + 6)^2 = -12*(y + 2)
(x^2/81) + (y^2/100) = 1
First, we can see that the second one is an ellipse, and we can write it as:
(x/9)^2 + (y/10)^2 = 1
This adds some complexity to our problem.
The first equation is just a quadratic equation, that we can write in standard form as:
y = (x^2 + 12*x + 36)/(-12) - 2
y = (-1/12)*x^2 - x - 5
Then our two equations are:
(x/9)^2 + (y/10)^2 = 1
y = (-1/12)*x^2 - x - 5
This is actually really hard to solve analytically, we may end with a quartic equation or something like that (this happens for the nature of the ellipse equation)
So now that we have two rather simple equations that we know how to graph (or that we can just input the equations in a program and graph them) we can find the intersections visually.
You can see the graph of this below:
Of course, this only works to find estimations for the intersections, where one intersection is (3.35, -9.28) and the other is at (-8.69, -2.6)
