Solve for x: 7x + 15 = 38
A: 23/7
B: 53/7
C: 23
D: 53
Answers
Step by Step: to isolate 7x, subtract 15 from both sides of the equation. 15-15=0. 38-15=23.
now the equation is 7x=23
finally, to completely isolate the variable, divide 7 from both sides. 7x/7= x. 23/7=23/7 because it cannot be simplified further unless you want it to be a decimal.
so the answer is A, 23/7
The rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental. The graph shows points representing the total cost of the rental. Which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = 20x +40 y = x + 50 y = 50x + 25 y = 25x y = 75x
Answers
Answer:
Step-by-step explanation:
y= 20x+40
y- is the cost of rental
x-number of days
20 is the slope
40-flat rate and the y-intercept is at (0,40)

Check for valid triangles
Given 3 sides of a triangle: A triangle is valid If the sum of any two sides is greater than the third
1. Sides: 2cm, 3cm and 4cm
To check:
2cm + 3cm > 4cm --- True
2cm + 4cm > 3cm ---- True
3cm + 4cm > 2cm ----- True
The above conditions are true, hence the input values form a triangle.
2. Sides: 2cm, 3cm and 6cm
To check:
2cm + 3cm > 6cm --- False
2cm + 6cm > 3cm ---- True
3cm + 6cm > 2cm ----- True
One of the above conditions is false. Hence, the input values do not form a triangle.
Given the angles of a triangle, their sum must be equal to 180°
3. Angles: 90°, 45° and 45°
Sum = 90° + 45° + 45°
Sum = 180°
This is a valid triangle because the sum equals 180°
4. Angles: 90°, 60° and 60°
Sum = 90° + 60° + 60°
Sum = 210°
This is not a valid triangle because the sum does not equal to 180°
The above conditions are true, hence the input values form a triangle.

In a group of 10 boys each boy had 2hats how many hats did they have
Answers
Answer:
20 hats
Step-by-step explanation:
If one boy had two hats, and there were ten boys, you would simply multiply 10 by 2! that gets you 20, which is your answer!
You can think of it as instead of each boy having one hat (which would make it ten hats in total), they'd have double of ten, making it 20!

Elena bought 8 tokens for $4.40. At this rate: 1)How many tokens could she buy with $6.05? 2) How much do 19 tokens cost?
Answers
Step-by-step explanation:
First you need to find how much each token costs.
to do this, we need to divide the cost by the number of tokens.
4.40 ÷ 8 = 0.55. So, each token costs 55 cents/ $0.55.
Next, you need to find how many tokens she can afford.
to do this, we need to divide how much money she has by the cost of each token.
6.05 ÷ 0.55 = 11. So, she can buy 11 tokens in total.
Answer: She could buy 11 tokens and 19 tokens cost 10.45
Step-by-step explanation:
divide how much money you spent by how many tokens you bought
4.40/8=0.55 x 19= 10.45
6.05/0.55=11
Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?
Answers
Answer:
FV= $8,436
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,700
Simple interest (i)= 8% = 0.08
Number of periods (n)= 6 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*i*n + PV
FV= 5,700*0.08*6 + 5,700
FV= $8,436

Find coordinates of the image of the point A(3,9) for a dilation with the scale factor of 2/3
Answers
Answer:
The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)
Step-by-step explanation:
Given the point A with the vertices (3, 9) i.e. A(3,9)
As we know that If the scale factor is between 0 and 1, the image gets shrunk.
In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.
i.e.
(x, y) → (2/3 x, 2/3 y)
so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:
A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)
Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

Write your result in scientific notation.

GivenNumber of people:
6 million = 6*10^6Distance to walk:
2.5 miles per day per personDistance around the Earth
2.5*10^4SolutionTotal distance walked:
6*10^6*2.5 = 15*10^6The ratio of total distance to the distance around the Earth:
15*10^6 / 2.5*10^4 = 6*10^2 = 600 timesNumber of people:
6 million = [tex]6[/tex] × [tex]10^{6}[/tex]
Distance to walk:
2.5 miles every day per person

When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.
Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.
See the drawing attached below.
Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:
m<DIE + m<HID = 18
40 + m<HID = 180
m<HID = 140
Similarly:
m<BHC + m<CHI = 180
130 + m<CHI = 180
m<CHI = 50
Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:
m<DIE = m<GIH = 40
m<GIE = m<HID = 140
m<CHI = m<AHB = 50
m<BHC = m<AHI = 130

Rebecca is distributing fidget spinners as part of her campaign for school president. she has 500 fridge my spinners to distribute in packs of 25 per teacher. write a function modeling this situation. define all unknown variables
Answers
Answer:
Y= 20
Step-by-step explanation:
From the question, Rebecca has 500 fridge my spinners to distribute in packs of 25 per teacher, we can denote the number of this teacher with "Y" then for her to distribute those 500 fridge in packs of 25 per teacher, then we can say (25× Y)= 25Y ,since she has 500 fridge in total to distribute then we can write a write a function modeling this situation as
25Y=500
where Y is the number of teacher
Make Y subject of the formula we have
Y= 500/25
Y=20
Answer:
25x=500 or x=20
Step-by-step explanation:
__
Well Rebecca have 500 fidget spinners so you put that on one end and let x be the number of teachers if you have 25 fidget spinners per teacher you need to multiply 25 by the number of teachers or x to find out so the equation will look like this: 25x=500
If you want to simplify you divide by 25 into both sides which are 20
