Answer:
2 cookies
Step-by-step explanation:
let c represent cookies, m represent muffins. set up a system of equations:
2c+3m=16
m=2c
(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).
then solve the system of equations by substitution, substituting 2c for m in the top equation:
2c+3(2c)=16
2c+6c=16
8c=16
c=2
this means that lori bought 2 cookies.
Answer:
2 cookies
Step-by-step explanation:
let c = no. of cookies
2c = no. of muffins
The cost for c cookies is 2c since each cookie was $2
and the cost of 2c muffins is 3(2c) = 6c since each muffing was $3
The total cost = 2c + 6c = 16
8c = 16
c = 2
So, she bought 2 cookies and 4 muffins

Answer:

Step-by-step explanation:
find the slope (1,1) and (2,3) do change in y over change in x then simplify
Answer:
2
Step-by-step explanation:
Find 2 easy-to-read points. Points that easy to read are on the intersection of grid lines.
For example, choose (1, 1) and (2, 3).
slope = rise/run
rise = difference in y
run = difference in x
Start at point (1, 1). To go to point (2, 3), first you go up 2 units. The difference in y is 2, so the rise is 2. Then you go 1 unit to the right. The difference in x is 1, so the run is 1.
slope = rise/run = 2/1 = 2
Answer: slope = 2
Sandy has a 10% discount off the total price before tax is added for Larry's Lunch Place. It
the cost of the meal is $18.50,
1. What is the cost of the meal after the discount? (WE DID THIS IN CLASS-copy from
classwork)
how would i do both of these, show work pls
Answer:
-12.5%
-14.29%
Step-by-step explanation:
For #2:
Original price is $2.00, that price decreased by $0.25 is $1.75. First figure out what $0.25 out of $2.00 is as a percent:
0.25/2.00 = 0.125 = 12.5%
Then, since the price DECREASED by $0.25, the percent would be negative.
For #4:
Original price is $3.50, that price decreased by $0.50 is $3.00. Like #2, you need to figure out what $0.50 out of $3.50 is as a percent:
0.50/3.50 = 0.1429 = 14.29%
Then, since the price DECREASED by $0.50, the percent would be negative.

Write an equation of a like that passes through the points (9,5) and (6,7)
Answer:
y=-2/3x+11
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-5)/(6-9)
m=2/-3
m=-2/3
y-y1=m(x-x1)
y-5=-2/3(x-9)
y=-2/3x+18/3+5
y=-2/3x+6+5
y=-2/3x+11
Which equation is equivalent to
1/5x-3=2/3
A 5X-45=3
B 3x - 15=10
C 3x-45 = 10
D X-15 = 10
Answer:
c) 3x - 45 = 10
Step-by-step explanation:
[tex]\frac{1}{5}x-3=\frac{2}{3}\\\\\frac{1}{5}x-\frac{3*5}{1*5}=\frac{2}{3}\\\\\frac{x-15}{5}=\frac{2}{3}\\[/tex]
Cross multiply,
3*(x - 15) = 2*5
3*x - 3*15 = 10
3x - 45 = 10

Points Y and Z are points of tangency. Find the value of a.
Answer:
a = 2Step-by-step explanation:
If Y and Z are points of tangency, then |XY| = |XZ|.
We have

Lance is an enthusiastic cyclist.
He uses an app on his phone to track each of his cycling sessions.
Below is shown some information about his last three.
In Lance’s last three cycling sessions.
(i) What was the shortest distance cycled?
(ii) What was the longest time that he cycled for?
(iii) Work out Lance’s cycling time.
Answer:
17.25 ; 1:01:13 ; 4 hours 47 minutes, 38 seconds
Step-by-step explanation:
From the picture attached :
The shortest distance cycled :
17.25 < 25.80 < 27.42
Hence, shortest distance cycled is : 17.25
Shortest cycling time :
1:01:13 < 1:50:05 < 1:56:20
Hence, shortest distance cycled is : 1:01:13
Total cycling time:
1:01:13 + 1:50:05 + 1:56:20
1 + 1 + 1 = 3 hrs
01 + 50 + 56 = 107 = 107/60 = 1 hr 47 minutes
13 + 05 + 20 = 38 seconds
Total cycling time :
(3 + 1 hr 47 minutes + 38 seconds) = 4 hours 47 minutes, 38 seconds
how do you find the area of a right triangle if you only have the base
Step-by-step explanation:
You can find the area of a right triangle the same as you would any other triangle by using the following formula:
A = (1/2)bh, where A is the area of the triangle, b is the length of the base and h is the height of the triangle; However, with a right triangle, it's much more convenient in finding its area if we utilize the lengths of the two legs (the two sides that are shorter than the longest side, the hypotenuse and that are perpendicular to each other and thus form the right angle of the right triangle), that is, since the two legs of a right triangle are perpendicular to each other, when we treat one leg as the base, then, consequently, we can automatically treat the length of the other leg as the height, and if we initially know the lengths of both legs, then we can then just plug this information directly into the area formula for a triangle to find the area A of the right triangle.
For example: Find the area of a right triangle whose legs have lengths of 3 in. and 4 in.
Make the 4 in. leg the base. Since the two legs of a right triangle are perpendicular to each other, then the length of the other leg is automatically the height of the triangle; therefore, plugging this information into the formula for the area of a triangle, we have:
A = (1/2)bh
= (1/2)(4 in.)(3 in.)
= (1/2)(12 in.²)
A = 6 in.² (note: in.² means square inches)
