Mrs. Martinez spent $15.25 buying candy for the 17 students in her G
eometry class. If m & m's cost $0.75 and Snickers
cost $1.00 how many of each did she buy?
1st step identify the variables x-m & m's y=Snickers
2nd Step Write 2 Equations x+y=17 0.75x+1.00y-15.25
3rd Step Solve the System using method of your choice SHOW ALL WORK
Xuy-y-17-y
X-17-y
Substitute 0.75(17-y) +1.00y-15.25
12.75-75y+1.00y=15.25
12.75+.25y-15.25
-12.75 -12.75
.25y-2.5
Divide by 25 y 10
Substitute x+10-17 x 7

Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.
Answers
Answer:
The answer is below
Step-by-step explanation:
Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship
Solution:
Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:
y = x + 15
You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.
Rodrigo: 10 20 30
Isabella: 25 35 45
When x = 10: y = x + 15 = 10 + 15 = 25
When x = 20: y = x + 15 = 20 + 15 = 35
When x = 30: y = x + 15 = 30 + 15 = 45

Two functions are graphed on the coordinate plane.
On a coordinate plane, a curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A straight horizontal line, labeled f of x, crosses the y-axis at (0, 4).
Which represents where f(x) = g(x)?
f(4) = g(4) and f(0) = g(0)
f(–4) = g(–4) and f(0) = g(0)
f(–4) = g(–2) and f(4) = g(4)
f(0) = g(–4) and f(4) = g(–2)
Answers
Answer:
Answer:
(B) f(-4)=g(-4) and f(0)=g(0)
Step-by-step explanation:
From the given graph, the lines f(x) and g(x) intersects at two different points.
When x=-4, f(-4)=4 and g(-4)=4
When x=0, f(0)=4 and g(0)=4
Therefore, the points which represent where f(x)=g(x) are:
f(-4)=g(-4); and
f(0)=g(0)
The correct option is B.

jack finds this list of ingridents needed to make 20 muffins. To make 20 muffins you need 220ml milk, 250g castel sugar, 400g flour.
Jack has these ingridents : 1 litre of milk, 750g caster sugar and 1.5kg flour. Work out the greatest number of muffins Jack can make with his ingridents!
Answers
Answer:
60 muffins
Step-by-step explanation:
Find out how much ml you need for each ingredient.
20 muffins =
220 ÷ 20 = 11 (milk)
250 ÷ 20 = 12.5 (castel sugar)
400 ÷ 20 = 20 (flour)
Find out the greatest number of muffins Jack can make.
1 litre = 1000 ml
1000 ÷ 11 = 90.90 (recurring decimal) (milk)
750 ÷ 12.5 = 60 (castel sugar)
1500 ÷ 20 = 75 (flour)

A bag contains 35 red counters only. Chen adds green counters to the bag. The probability of picking a green counter is now 0.3 How many green counters did Chen add?
Answers
Answer:
15
Step-by-step explanation:
Red counters = 35
Number of green counters = x
P(picking a green counter) = 0.3
Probability = required outcome / Total possible outcomes
Required outcome = number of green counter
Total possible outcomes = green counter + red counter
Hence,
0.3 = x / (35+x)
0.3(35 + x) = x
10.5 + 0.3x = x
10.5 = x - 0.3x
10.5 = 0.7x
x = 10.5 / 0.7
= 15
Number of green counters = 15
