Samir goes to a farmers market to buy some fruit.
He fills a large bag with 29kg of apples.
He realises that he cannot carry this weight, so puts some of the apples into a smaller bag.
The weight of the apples in the large bag is 15kg larger than the smaller bag.
(a) What is the weight of the smaller bag?
Answer:
Weight of Smaller Bag = 7kg
Weight of Larger Bag = 22kg
Step-by-step explanation:
x = weight of smaller bag
x + (x + 15) = 29
2x + 15 =29
2x = 14
x = 7

Answer:
a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )
Step-by-step explanation:
a)
3x + y = -5
y = -3x -5
b)
y = 1/3 ( 21 - 9x)
y = -3x + 7
y = 3x + 2.5

An employee at an electronics store makes $12 per hour plus commission of 4.5% of her sales. This week she has sold 36 television averaging $620 each.What is her commission this week?
Answer: $1004.4
Step-by-step explanation:
Simple math
The total commission of the employee will be $1004.4 for the given sale.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
4.5% of commission on sales.
Total selling = 36 x 620 = $22320
4.5% of $22320 = (4.5/100)22320 = $1004.4
Hence "The total commission of the employee will be $1004.4 for the given sale".

Answer: -10x+9
Step-by-step explanation:
please may you help me quick timeee
Answer:
Step-by-step explanation:
tan e = x/(4x-1)
tan f = (6x+5)/(12x + 31)
since tan e = tan f
x/(4x-1) = (6x+5)/(12x+31)
x(12x+31) = (4x-1)(6x+5)
12x^2 +31x = 24x^2 +20x -6x -5
31x = 12x^2 +14x -5
0 = 12x^2 -17x -5
0 = (12x -5)(x -1)
x = 1, 5/12

10 2.5 16 4 ? 7.5 48 12 Which statement explains how to find the number of minutes it takes to bike 7.5 miles? Find the ratio of minutes to miles, 4:1. Divide 7.5 by 4. Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4. Find the difference between 16 and 10. Add the difference to 16. Find the difference between 16 and 10. Add the difference to 7.5.
Answer:
Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Step-by-step explanation:
Given
Minutes: 10 || 16 || ? || 48
-----Miles: 2.5 || 4 || 7.5 || 12
Required
Which statements solve for the missing value?
First, we need to calculate the ratio of minutes to mile
[tex]Ratio = \frac{Minutes}{Mile}[/tex]
When minutes = 16; mile = 4
So, we have:
[tex]Ratio = \frac{16}{4}[/tex]
[tex]Ratio = 4[/tex]
Next, we multiply the ratio by 7.5
[tex]Minutes = Ratio * 7.5[/tex]
[tex]Minutes =4 * 7.5[/tex]
[tex]Minutes = 30[/tex]
Hence, option B answers the question.

Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located?
Select ALL that apply.
−1
1
15
−15
Answer:
The correct answers are: 1 and -15
Step-by-step explanation:
Let a be a point on number line and b be the second point on number line.
The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.
Here
AB = 8
B = -7
We have to look at the options one by one.
For A = -1
As A>B
[tex]AB = B-A = -1-(-7) = -1+7 = 6[/tex]
For A = 1
As A>B so
[tex]AB = A-B = 1-(-7) = 1+7 = 8[/tex]
So with A = 1 , AB = 8
This is one of the right answers.
For A=15
As A>B
[tex]AB = A-B = 15-(-7) = 15+7 = 22\\[/tex]
For A=-15
As B>A
[tex]AB = B-A = -7-(-15) = -7+15 = 8[/tex]
As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.
Hence,
The correct answers are: 1 and -15

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.
If y varies as directly as the square of x, and y = 75/8 when x = 5, find y when x= 2
Answer:y=15/4
Step-by-step explanation:
start with general form y = kx. substitute in the pair of values you know for x and y.
75/8 = k(5) multiply both sides by 1/5 to solve for k, getting
15/8 = k
So your equation is y = (15/8)x substitute 2 for x to find your new y.
y = (15/8)2
y = 15/4
A car’s wheels spin at 1000 revolutions per minute. The diameter of the wheels is 23 inches. You want to know how fast the car is travelling.
A:Circumference
B:Area
Answer:
Speed = 72,285 in/min
Step-by-step explanation:
Given:
Total revolution per min = 1,000
Diameter = 23 in
Radius = 23/2 in
Time = 1 min
Find:
Speed
Computation:
Total distance = 2πr(1000)
Speed = Distance / time
Speed = 2πr(1000) / 1
Speed = 2π(23/2)(1000) / 1
Speed = 72,285 in/min
