Answer:
Each shirt costs $ 10, while each short costs $ 15.
Step-by-step explanation:
Since two brothers went shopping at a back to school sale where all shirts and shorts are the same price, and the younger brother spent $ 175 on 7 new shirts and 7 pairs of shorts while the older brother purchased 6 new shirts and 7 pairs of shorts and paid a total of $ 165, to determine the price of each shorts and each shirt the following system of equations must be considered:
Shirt = X
Short = Y
7X + 7Y = 175
6X + 7Y = 165
7X - 6X + 7Y - 7Y = 175-165
X = 10
7x10 + 7Y = 175
70 + 7Y = 175
7Y = 175 - 70
Y = 105/7
Y = 15
Thus, each shirt costs $ 10, while each short costs $ 15.

is going to plant y vegetable seeds in one garden and 3y+8 vegetable seeds in another. How many seeds is Frank going to plant?
Answer:
4y + 8 vegetable seeds
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Terms/CoefficientsStep-by-step explanation:
We know that Frank has 2 gardens, one with y vegetable seeds and another with 3y + 8 vegetable seeds. If we are trying to find the total amount of seeds planted, we must add the 2 gardens together:
Garden 1: y
Garden 2: 3y + 8
Garden 1 + Garden 2 = Total veggie seeds
y + 3y + 8 = Total veggie seeds
Total veggie seeds = 4y + 8

need help horribly geometry question
Answer:
23.31 ft
Step-by-step explanation:
Reference angle = 47°
Opp = 25 ft
Adj = x
Apply trigonometry ratio TOA:
Tan 47 = Opp/Adj
Tan 47 = 25/x
x*Tan 47 = 25
x = 25/Tan 47
x = 23.3128772 ≈ 23.31 ft (to 2 d.p)

The human resources department of an engineering company gives IQ tests to a randomly selected group of new hires every year. They claimed that the mean IQ score of new hires, , from this year is greater than or equal to the mean IQ score of new hires, , from last year. This year, 95 new hires took the test and scored an average of 112.2 points with a standard deviation of 14.0 . Last year, 70 new hires took the IQ test and they scored an average of 117.8 points with a standard deviation of 14.5 . Assume that the population standard deviation of the IQ scores from the current year and the last year can be estimated by the sample standard deviations, since the samples that are used to compute them are quite large. Is there enough evidence to reject the claim of the human resources department, at the 0.01 level of significance
Answer:
Step-by-step explanation:
Null hypothesis: [tex]\mathbf{H_o: \mu_1 \ge \mu_2}[/tex]
Alternative hypothesis: [tex]\mathbf{H_o: \mu_1< \mu_2}[/tex]
This type of test statistic is a z test statistics
1st 2nd
Sample mean x = 112.2 117,8
Standard deviation σ = 14.0 14.5
Sample size n = 95 70
Point estimate [tex]\bar x_1 - \bar x_2[/tex] = -5.60
Standard error [tex]\sigma_{x_1-x_2}= \sqrt{\dfrac{\sigma_1^2}{n_1} +\dfrac{\sigma_2^2}{n_2} }[/tex]
[tex]= \sqrt{\dfrac{14.0^2}{95} +\dfrac{14.5^2}{70} }[/tex] = 2.2509
Test statistics [tex]z=\dfrac{x_1 - x_2}{\sigma_{x_1-x_2}}[/tex] [tex]=\dfrac{112.2- 117.8}{2.2509}[/tex] = - 2.4878
P-value = 0.012
No, there is no enough evidence Since p-value is greater than 0.01.

I need to do this class soon, please help me
Answer:
Step-by-step explanation:
18. x + 25 = 55
x = 30
19. 2x - 5 = 95
2x = 100
x = 50
20. 3x - 22 = 2x + 26
x - 22 = 26
x = 48
21. 3x - 18 + 105 = 180
3x + 87 = 180
3x = 93
x = 31
22. 19x + 17x = 180
36x = 180
x = 5
27(5) = 135
23. 5x + 40 + 2x = 180
7x + 40 = 140
7x = 140
x = 20
5(20) = 100
2(20) = 40
5(20) + 40 = 100 + 40 = 140

AD is the perpendicular bisector of BC.
BD = 5x – 10 and DC = 3x + 10.
Determine the value of x.
5x-10= 3x+10
5x-3x= 10+10
2x÷2= 20÷2
x= 10
Step-by-step explanation:
as AD bisects them they will be two equal parts so
5x-10=3x+10
5x-3x=10+10
2x=20
divide both sides by 2 and
x=10

The answer in this picture is B(143)
Answer:
A
Step-by-step explanation:
180 _80 =100
180_65= 115
180_72 = 108
Then :
108 + 115 + 100 = 323
Then :
360 _ 323 = 37
Then :
180 _37 = 143
X _7 =143
X =150
