Answer:
f=1
Step-by-step explanation:
Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.

Step-by-step explanation:
Priya drew a triangle with the side lengths 3, 4, 5. She wants to draw a triangle that is a SMALLER scaled copy. Which of the following are scale factors she could use to make the triangle smaller?
Answer:
She could make the triangle smaller by making the same triangle but smaller and add the same sides to the small triangle.
scale factors she could use to make the triangle smaller is [tex]\frac{1}{2}[/tex]
Given :
Priya drew a triangle with the side lengths 3, 4, 5
Given options are :
1.) 1/2
2.) 1
3.) 2
4.) 6
Explanation :
The ratio of the measurement of the corresponding sides of a triangle is a scale factor .
When we multiply the side length by a scale factor >1 that gives a bigger scaled copy
When we multiply the side length by a scale factor <1 that gives a smaller scaled copy
From the given options , scale factor 1/2 is less than 1
So 1/2 is the scale factor that could use to make the triangle smaller

What are each of the steps on solving 5x-2+ 3x=14. There are four steps and the choices are combine like terms, addition, subtraction, division, and distribution.
Answer:
5x - 2 = 3x = 14
8x -2 = 14
8x = 14 + 2
8x = 16
x = 2
Step-by-step explanation:
Answer:
add 5x and 3x then add -2 to 14. it should be 8x=12 then divide 8x and 12 by 8 and its 12/8 or simplify to 6/4 or 1 1/2 so combine like terms then addition then division i think :)

ABC is a triangle in which B = 90°. In each of
these, i draw and label a sketch, ii then calculate
b
the length of the third side of the triangle.
AB = 6 m, BC = 8 m
Step-by-step explanation:
You have to use pythagoras' theorem for this.
So AC is the length you want to find.
Pythagoras' theorem is a^2+b^2=c^2
In your triangle, AB=a, BC=b and AC=c
6^2+8^2=Ac^2
36+64= AC^2
100=AC^2
Square root both sides
10=AC
Therefore AC=10m

To sketch the graph of y = (x - 3)2 + 2, the graph of y = x2 will need to be translated:
A 3 units to the left and 2 units up.
B 3 units to the right and 2 units up.
C 3 units to the left and 2 units down.
D 3 units to the right and 2 units down.
B
Step-by-step explanation:
since the formula requires you to subtract the x value, if the x value were to be negative(left) then the equation would be (x+3) because minus minus equals to plus but in this case it is (x-3) that means that the x value was positive.

Sarah's gross income last month was £1260.
She pays 20% tax on her gross income.
How much tax did Sarah pay last month?
ایا
Answer: 252
Step-by-step explanation:
The amount of tax paid by Sarah last month is £252.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Sarah's gross income last month was £1260. She pays 20% tax on her gross income.
The tax amount is calculated by taking 20% of the gross income £1260.
Tax amount = 20% of £1260.
Tax amount = £1260 x 20 /100
Tax amount = £1260 / 5
Tax amount =£252.
Therefore, the amount of tax paid by Sarah last month is £252.

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on the shirts. Select all the equations that could represent the relationship between the number of T-shirts ordered, the number of colors on the shirts(x), and the total cost of the order(y).
Answer:
y= 50x+ 225 \Step-by-step explanation:
Given that
the number of colors on the shirts(x), and
the total cost of the order(y).
since the number of colors is given as x
the total cost y can be represented as
y= 50x+ 75(3)
y= 50x+ 225
hence the total cost of 75 T-shirts is given by the model

is {(3,4),(3,5),(4,4), (4,5)} a function
Answer:
No, it's not a function.
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. Therefore, this is not a function.

Is the square root of 18 closer to 4 or 5
i need to find the area .
Answer:
105.12 ft^2
Step-by-step explanation:
Area of rectangle = 8 × 10 = 80 ft^2
Area of semicircle = 1/2π × 4^2
4 is the radius of the semicircle.
Since we use 3.14 to approximate π...
Area of semicircle = 1/2× 3.14 × 4^2 = 25.12
∴Total area = 25.12 + 80 = 105.12 ft^2
Answer: 105.12ft²
Step-by-step explanation: first we need to find the area of the rectangle with the formula: length × width so, 8ft × 10ft = 80 ft².
Now we can find the area of the semicircle with the formula: πr²÷ 2 so, (3.14 × 4²) ÷ 2 = 25.12ft². Now we need to calculate the area of the whole shape and we can do this by adding together our rectangle and semicircle so, 80ft + 25.12ft = 105.12ft².

Answer:
75/7 = 105/7 (ten whole number, five over seven)
Step-by-step explanation:
1/3n + 25 = 2n
n is the number
n/3 + 25/1 = 2n
n + 75/3 = 2n
cross multiply
n + 75 = 6n
75 = 7n
n = 75/7
n = ten whole number, five over seven (105/7)
