A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?
Answer:
100%
Step-by-step explanation:
Let p = percent of cashews in first mix
2p = lb. of cashews in first mix
30(.20) = 6 = lb. of cashews in second mix
32(.25) = 8 = lb. of cashews in the combined mix
So,
lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix
2p + 6 = 8
2p = 2
p = 1 = 100%
Answer:
100%

Which expression best estimates 6 3/4 ÷ 1 2/3
7 ÷ 2
6 ÷ 1
8 ÷ 3
3 ÷ 2
Answer:
7 divided by 2
Step-by-step explanation:
I say 7 divided by 2 because if you round 6 3/4 up one you will get 7 and if you round 1 2/3 up one you get 2 so 7 divided by 2 makes most sense
3 teas and 2 coffees have a total cost of £7.80.
5 teas and 4 coffees have a total cost of £14.20.
Work out the cost of one tea and the cost of one coffee.
Answer:
coffee is £1.80 per cup and tea is £1.40 per cup
Step by Step:
The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup

3. Keith bought a soft drink for 4 dollars and 8 candy bars. He spent a total of 44 dollars. How much did each candy bar cost?
4. Tim bought 4 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 43 cards left. How many did Tim start with?
Answer: 1. 33 , 2. 21 , 3. $5.00 , 4. 39.
Step-by-step explanation:
4. Let the original number of baseball trading cards in Tim's possession be
x
An equation to arrive at the number will be:
x
+
9
2
=
24
This is because half the collection AFTER adding
9
new cards is
24
(the other half was eaten by his dog).
Multiply both sides by
2
.
x
+
9
=
48
Subtract

from both sides.

4x + 3(4x + 7) = 4(7x + 3)
Answer: 1
Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3
Reorder the terms:
4x + 3(7 + 4x) = 4(7x + 3) + -3
4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3
4x + (21 + 12x) = 4(7x + 3) + -3
Reorder the terms:
21 + 4x + 12x = 4(7x + 3) + -3
Combine like terms: 4x + 12x = 16x
21 + 16x = 4(7x + 3) + -3
Reorder the terms:
21 + 16x = 4(3 + 7x) + -3
21 + 16x = (3 * 4 + 7x * 4) + -3
21 + 16x = (12 + 28x) + -3
Reorder the terms:
21 + 16x = 12 + -3 + 28x
Combine like terms: 12 + -3 = 9
21 + 16x = 9 + 28x
Solving
21 + 16x = 9 + 28x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-28x' to each side of the equation.
21 + 16x + -28x = 9 + 28x + -28x
Combine like terms: 16x + -28x = -12x
21 + -12x = 9 + 28x + -28x
Combine like terms: 28x + -28x = 0
21 + -12x = 9 + 0
21 + -12x = 9
Add '-21' to each side of the equation.
21 + -21 + -12x = 9 + -21
Combine like terms: 21 + -21 = 0
0 + -12x = 9 + -21
-12x = 9 + -21
Combine like terms: 9 + -21 = -12
-12x = -12
Divide each side by -12.
x = 1
Simplifying
x = 1

Step-by-step explanation:
A class of 195 students went on a field trip. They took 19 vehicles, some cars and some buses. If each car
holds 5 students and each bus hold 25 students, how many buses did they take?
Answer:
Number of cars = 14
Number of buses = 5
Step-by-step explanation:
Let
x = number of cars
y = number of buses
x + y = 19 (1)
5x + 25y = 195 (2)
From (1)
x = 19 - y
Substitute x = 19 - y into (2)
5x + 25y = 195
5(19 - y) + 25y = 195
95 - 5y + 25y = 195
- 5y + 25y = 195 - 95
20y = 100
y = 100/20
y = 5
Substitute y = 5 into (1)
x + y = 19
x + 5 = 19
x = 19 - 5
x = 14
Number of cars = 14
Number of buses = 5
Based on the number of vehicles and the number that each vehicle can take, the number of buses required is 4 buses.
There are 19 vehicles which take 5 students each. This means that the number of kids entering buses will be:
= 19 x 5
= 95 students
The students entering buses will be:
= Total number of students - Kids in vehicles
= 195 - 95
= 100 students
If each bus takes 25 students, the number of buses required is:
= 100 students / 25
= 4 buses
In conclusion, 4 buses were taken.

25 Patricia bought 5 apples and 7 bananas for $12.65. Jose bought 10 apples and 8 bananas for $18.10 at the same grocery store. What is the cost of one apple?
Answer:
Apple cost $0.85
Banana cost $1.2
Step-by-step explanation:
Given data
let the number of apples be x
and the number of bananas be y
Patricia bought 5 apples and 7 bananas for $12.65
5x+7y= 12.65----------1
Jose bought 10 apples and 8 bananas for $18.10
10x+8y= 18.10-----------2
solve 1 and 2 above
5x+7y= 12.65 X 2
10x+8y= 18.10 X 1
10x+14y= 25.3
- 10x+8y= 18.10
6y= 7.2
y= 7.2/6
y= 1.2
put y= 1.2 in 1
5x+7(1.2)= 12.65
5x+ 8.4= 12.65
5x= 12.65- 8.4
5x= 4.25
x= 4.25/5
x= 0.85
Hence each apple cost $0.85
Banana cost $1.2

Please help! Also please don’t comment just for points it’s not funny and I need this so I can raise my score back up.
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.
HELP ASAP WILL GIVE 30 points. A toy box measures 4 ft by 3 ft by 2 ft. Explain whether increasing
the height by four times, from 2 ft to 8 ft, would increase the volume
by four times.
Answer:
yes, the volume would be increased by 4
Step-by-step explanation:
the volume for a box is l x w x h
lets say l = 4, w = 3, and h = 2
this would give us a volume of 24
now calculate the new volume: l x w x 4h
4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24
