How can I solve for x
Answer:
x = 10
Step-by-step explanation:
In similar polygons, the lengths of the sides are proportional.
(3x + 5)/42 = 30/36
(3x + 5)/42 = 5/6
6(3x + 5) = 5 × 42
18x + 30 = 210
18x = 180
x = 10
Answer:
x=10
Step-by-step explanation:
7.
[tex]\frac{3x+5}{42} =\frac{30}{36} \\3x+5=\frac{30}{36} \times 42\\3x+5=35\\3x=35-5=30\\x=\frac{30}{3} =10[/tex]

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes.
Calculate the price per roll for each shop.
Write which shop is the best value for money in the comment box.
Step-by-step explanation:
Lidal : 9 rolls for £3.51
1 roll for 3.51/9 = £0.39
Oldi : 4 rolls for £1.52
1 roll for 1.52/4 = £0.38
so, Oldi has the best value for money when buying toilet rolls.

[tex]a^{x} *a^{y} =a^{x+y}[/tex]
[tex]a^{-x} =\frac{1}{a^{x} }[/tex]
[tex]\frac{1}{a^{-x} } =a^{x}[/tex]
Let's solve now

percent change of 10 and 24
Answer:
140%
Step-by-step explanation:
(24-10) / 10 = 14/10 = 140%
Answer:
140%
Step-by-step explanation:
A change from 10 to 24 represents a positive change (increase) to 140%.
Percent change = New-Old/Old x 100%
Percent change = 24-10/10 x 100% =
14/10 x 100 = 140% (increase)
Where 10 is the old value and 24 is the new value. In this case, we have a positive change (increase) of 140 percent because the new value is greater than the old value.
David made an error when determining the product of (–2.5)(–8.3).
Step 1: (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2: = (–8.3)(–2) + (–8.3)(–0.5)
Step 3: = (–16.6) + (–4.15)
Step 4: = –20.75
In which step did David make his first error?
Answer:
step 3
Step-by-step explanation:
when you multiply an even amount of negative numbers you will always get a positive result thus the answe would be 16.6 + 4.15 as in positive numbers
Find the slope of the line that passes through the points (4,1) and (-2.7).
What is the slope of a line perpendicular to this line?
Answer:
the slope=-1 the slope perp=1
Step-by-step explanation:
to find slope perpendicular you just have to multiply your slope by something and have it equal -1
for example
1/2x=-1
the slope perpendicular to a line with the slope of 1/2 would be -2 beacause 1/2x-2=-1
so the slope x perpendicular slope = -1

Select the correct answer Which equation represents a line that is perpendicular to line MN?
Answer:
D. y = 4x - 6
Step-by-step explanation:
The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,
Therefore,
m₁ × m₂ = -1
Using the 2 coordinates of MN let's find the slope,
(-7, 6)(5, 3)
Therefore,
m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4
The equation that represent a line perpendicular to the line MN is
y = 4x - 6 because the slope slope(m₂) is 4.
From our formula,
4 × - 1 / 4 = - 1
So, option D meets the requirement.
Answer:
D. y = 4x - 6

Answer:
D- Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen.
Step-by-step explanation:
The situation is an example of an observational study is "Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen:.
What is an observational study?When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.
For example: Consider someone standing on a popular street in a New York neighborhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.
As we know that in an observational study, the sample whose test/survey is been taken is completely random.
Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favorite brand of toothpaste".

Tell whether the lines through the given points are parallel, perpendicular, or neither.
Line 1: (6, 5), (4,2)
Line 2: (-8, -1), (-2, 8)
Answer: Line 1: (2, 3) , (4, 12)
m = (12 - 3)/(4 - 2) = 9/2 This is the slope of the line
y = (9/2)x + b
3 = (9/2)(2) + b
3 = 9 + b
b = -6
y = (9/2)x - 6
Line 2: (5, 10) , (14,8)
m = (8 - 10)/(14 - 5) = -2/9
this slope is the opposite sign, and inverse of the first equation's slope. Therefore, the line is perpendicular.
y = mx + b
8 = (-2/9)(14) + b
8 = -28/9 + b
11.11 = b
y = (-2/9)x + 11.11

need help with this part
Answer:
1. 42 people can be seated
2. 16 tables should be used.
Step-by-step explanation:
Part 1:
Since we are given the function, p(n) = 4n + 2, we need to plug in 10 to "n." This is because "n" represents the number of tables as stated on the top of the pciture. And "p(n)" represents the number of people that can be seated.
p(n) = 4(10) + 2
p(n) = 40 + 2
p(n) = 42
Part 2:
For this question, since we are given 65 as the total number of people that can be seated, we would plug in 65 in "p(n)", to result in the following equation.
p(65) = 4n + 2
Then solve the equation and use the property of inverse operation.
65 = 4n + 2
65 - 2 = 4n + 2 - 2
63 = 4n
63/4 = 4n/4
15.75 = n
Although we're given 15.75 as the number of tables that should be used, we can't really have a 0.75 of a table, so we would round 0.75 to 1.
15 + 1 = 16
16 tables are required.

Answer:
A. 4
Step-by-step explanation:
So, we have an equation with a variable (g), and they've given us the value of g to be -2. All we have to do at this stage is plug in the value of g into the equation.
-5g-6 (g=-2)
-5(-2)-6
10-6=4
