1. The ratio of red marbles to blue marbles
in a bag is 2 to 5. If there are 60 more
blue marbles than red marbles in the
bag, how many marbles are there all
together?
Answer:
84
Step-by-step explanation:
Cross multiply to solve for the red marbles
Let x = the number of red marbles
2/5 = x/60
Cross multiply
2(60)/5 = x
x = 24 which is the number of red marbles.
60 blue plus 24 red = 84 total marbles.
A chemist has two solutions of HNO3. One has a 40% concentration and the other has a 25% concentration.
How many liters of each solution must be mixed to obtain 57 liters of a 26% solution?
Step-by-step explanation:
Let +a+ = liters of 40% solution needed
Let +b+ = liters of 25% solution needed
+.4a+ = liters of HN03 in 40% solution
+.25b+ = liters of HN03 in 25% solution
------------------------------------
(1) +%28+.4a+%2B+.25b+%29+%2F+57+=+.26+
(2) +a+%2B+b+=+57+
-----------------
(1) +.4a+%2B+.25b+=+.26%2A57+
(1) +.4a+%2B+.25b+=+14.82+
(1) +40a+%2B+25b+=+1482+
Multiply both sides of (2) by +25+
and subtract (2) from (1)
(1) +40a+%2B+25b+=+1482+
(2) +-25a+-+25b+=+-1425+
+15a+=+57+
+a+=+3.8+
and, since
(2) +a+%2B+b+=+57+
(2) +3.8+%2B+b+=+57+
(2) +b+=+53.2+
3.8 liters of 40% solution are needed
53.2 liters of 25% solution are needed

The highest common factor (HCF) of two numbers is 6.
The lowest common multiple (LCM) of the same numbers is 60
What are the two numbers?
Please explain every step
Answer:
12 and 30
Step-by-step explanation:
HCF = 6 = 2×3 means they both have in common a factor of 2 and a factor of 3, but at least one of the numbers has no more than one of each of these factors.LCM= 60=2²×3×5 means That the combined product of their factors counting only once the ones they have in common is 60.so they could be 2×2×3 = 12 and 2×3×5 = 30

Answer: y= -3x + 16
Step-by-step explanation:
I'm assuming that you mean a linear equation
So the first thing that you want to do is find the slope for the line.
1-(-2) / -3 - 6= -9/3= -3
Now that you have the slope you can pick one of the points to plug in.
-2 = -3(6) + b
We don't know what the y intercept is so we'll need to solve for that.
-2= -18 + b
add -18 to -2
16=b
so your equation will be
y= -3x + 16

Answer:
It's D; 32 ounces, because you get more for the price.
Answer:
A. 10 oz
Step by step explanation:
The question asks which one has the lowest unit price. The key word is unit, not just what is shown on the chart. You have to divide the price by the number of ounces to get the price for one ounce(unit). Then you look at all the prices and whichever one is the lowest is the answer. These are the unti prices after you divide the price by the number of oz

Answer:
16
Step-by-step explanation:
Ethan, Caleb, and Jayden went to a bakery to buy desserts. Ethan bought 2 cupcakes, 2
brownies and a pie for $20. Caleb bought 4 cupcakes, 4 brownies and a pie for $44, Jayden
bought 5 cupcakes and 6 brownies for $40. Write a system of equations to represent is
situation. Convert the system to a matrix and find the cost of 1 cupcake, 1 brownie, and 1
pie to the nearest cent.
Answer:
x = 32
y = -20 and
z = -4
Step-by-step explanation:
Cupcakes = X
Brownies = Y
Pies = Z
Ethan = 2x+2y+z = 20
Caleb = 4x+4y+z = 44
Jayden = 5x+6y = 40
-1(2x+2y+z=20) =
(-2x - 2y - z = -40) + (4x+4y+z=44)
= 5x + 6y = 40
-3(2x+2y=24 =
(-6 - 6y = -72) + (5x + 6y = 40)
= - x = - 32
= x = 32
5 (32) + 6y = 40
= 160 + 6y = 40
6y = 40 - 160
y = 120/6
y = - 20
2(32) + 2(-20) + z = 20
64 - 40 + z = 20
z = 20 - 24
z = -4
Current rules for telephone area codes allow the use of digits 2-9 for the first digit, and 0-9 for the second and third digits, but the last two digits cannot both be 1 (to avoid confusion with area codes such as 911). How many different area codes are possible with these rules? That same rule applies to the exchange numbers, which are the three digits immediately preceding the last four digits of a phone number. Given both of those rules, how many 10-digit phone numbers are possible? Given that these rules apply to the United States and Canada and a few islands, are there enough possible phone numbers? (Assume that the combined population is about 400,000,000.)
Using the fundamental counting theorem, we have that:
648 different area codes are possible with this rule.There are 6,480,000,000 possible 10-digit phone numbers.The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.The fundamental counting principle states that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are ways to do both things.
For the area code:
8 options for the first digit.9 options for the second and third.Thus:
[tex]8 \times 9 \times 9 = 648[/tex]
648 different area codes are possible with this rule.
For the number of 10-digit phone numbers:
7 digits, each with 10 options.648 different area codes.Then
[tex]648 \times 10^7 = 6,480,000,000 [/tex]
There are 6,480,000,000 possible 10-digit phone numbers.
The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.

For Exercises 8 and 9, find the lengths of all three sides of the triangle.
9514 1404 393
Answer:
8. GH = 49; HJ = 35; JG = 35
9. KL = 26, LM = 26, MK = 20
Step-by-step explanation:
8. The sides opposite the marked angles are congruent.
JG = JH
3x +8 = 35
3x = 27 . . . . . . . subtract 8
x = 9 . . . . . . . divide by 3
We already know JG and JH, so we only need to find GH:
GH = 6x -5 = 6(9) -5 = 54 -5 = 49
Then the side lengths are ...
GH = 49, HJ = 35, JG = 35
__
9. This, too, is an isosceles triangle.
LK = LM
26 = 2y+8
18 = 2y . . . . . . . subtract 8
y = 9 . . . . . . . divide by 2
KM = 3(9) -7 = 27 -7 = 20
Then the side lengths are ...
KL = 26, LM = 26, MK = 20

A truss or staircase frame from the custom steel products cost $2.25 for each rod plus $50for shipping and handling
The equation that can be used to represent the cost paid for the staircase frame is 50 + 2.25x
Based on the information given, let the number of rods be represented by x.
Fixed cost = $50
Variable cost = $2.25 × x = 2.25x
Therefore, the equation to calculate the total cost will be:
= Fixed cost + Variable cost
= 50 + 2.25x
Therefore, the equation to represent the fact that the staircase frame cost $2.25 for each rod plus $50 for shipping and handling is 50 + 2.25x
