Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)
Maria wants to buy a pair of shoes for $22.50 and a shirt for $13.50. If the sales tax rate is 8.25%, what will be the amount of sales tax on Maria’s purchase?
Answer:
$2.97
Step-by-step explanation:
- add together the prices of the items; 22.50 + 13.50 = 36
- multiply the total by the tax; 36 x 8.25% or 36 x 0.0825 = 2.97
- The total sales tax is $2.97
2x+7y=3 and x=-4y with substitution ?
Answer:
x=12
y=-3
Step-by-step explanation:
Because we already know what the value of x, we can use that value, -4y, to substitute it into the equation 2x+7y=3.
2(-4y)+7y=3 Simplify.
-8y+7y=3
-y=3 Divide both sides by -1 (to make y positive).
y=-3
Now, we can substitute y into the other equation, x=-4y.
x=-4(-3) Simplify.
x=12

what is the purpose of a statistical control chart?
The statistical control chart is discussed below.
What is statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.Given is the statistical control chart.
The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.Parts of a control chart -Points representing a statistic (e.g., a mean, range, proportion) of measurements of a quality characteristic in samples taken from the process at different times (i.e., the data)The mean of this statistic using all the samples is calculated (e.g., the mean of the means, mean of the ranges, mean of the proportions) - or for a reference period against which change can be assessed. Similarly a median can be used instead.A centre line is drawn at the value of the mean or median of the statisticUpper control and lower control limits (sometimes called "natural process limits") that indicate the threshold at which the process output is considered statistically 'unlikely' and are drawn typically at 3 standard deviations from the center line.Therefore, the statistical control chart is discussed above.

Answer:
x=3
Step-by-step explanation:
Answer:
Perimeter of the first triangle :[tex] \longmapsto(x - 4) + (x - 5) + 5 \\ = x - 4 + x - 5 + 5 \\ = \boxed{2x - 4}[/tex]
Perimeter of the second triangle :[tex] \longmapsto(x - 10) + 10 + 16 \\ = x - 10 + 10 + 16 \\ = \boxed{x + 16}[/tex]
Now, it is given that the two triangles have same perimeter
So equating the value of the perimeter of the two triangles, we get
[tex] 2x - 4 = x + 16 \\2x - x = 16 + 4 \\ \boxed{ x = 20}[/tex]
Therefore, the value of x is 20
x = 20 is the right answer.Which phone service offers the better deal option 1: 450 minutes for 49.99 option 2 : for 800 minutes for 62.99
Answer:
Option 1 : 450 minutes for $49.99

Find the slope-intercept form of the line passing
through the point (8,7) and parallel to the line
y = - 2x - 5.
Answer:
y = -2x + 23.
Step-by-step explanation:
If the line is parallel to
y = -2x - 5,
that means it has the SAME SLOPE. Parallel lines have the same slope, but they could have different y-intercepts.
The slope intercept form is:
y = mx + b.
m = slope.
b = y intercept.
In this case, the slope is -2.
So we know the answer will have a slope of -2.
So we can write:
y = -2x + b.
We just have to finish the answer by replacing "b" with a number.
To find out what "b" is, we plug in the point (8,7).
To plug this point in, we replace "x" with 8 and "y" with 7.
7 = -2(8) + b.
7 = -16 + b.
Now to get b by itself to solve for b, we have to add 16 to both sides.
7 + 16 = b.
b = 23.
So our final answer is: y = -2x + 23.

How many zeros will be in the product of 5 x 105 = ________? Explain how you know.
Answer:
The is zero 0's in the answer. The way I know is that I put it into an equation, and started solving. I started off by multiplying 5x5=25. Next I noticed the next number I multiply 5 by is 0, so the next value will be 2 because the 2 from 25 was carried over. Finally I multiplied 100x5=500. And 500+25=520.

The total pay Tom earn for working 11 hours is £185
Given that Tom is paid £15 if he works for less than 7 hours and then paid 1 1/3 times his normal salary if he works more than 7 hours.
Given that he works for 11 hours, hence:
Pay for the first 7 hours = £15 × 7 hours = £105
Pay for the overtime = 1 1/3 × £15 × (11 - 7) = 4/3 × £15 × 4 = £80
Total pay = £80 + £105 = £185
Hence the total pay Tom earn for working 11 hours is £185

Answer:
-3s + 6
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of the same variables. In this case:
8s - 11s + 6
(8s - 11s) + 6
-3s + 6
-3s + 6 is your answer.

Answer:
-3s + 6
Step-by-step explanation:
In order to find the answer you need to combine like terms. When you combine like terms you need to combine integers that have the same variable in this case 8 and 11 need to be combined due to the fact they both have the variable s.
8s - 11s + 6
(8s - 11s)
(8s - 11s) + 6
8s + -11s = -3s
