Answer:
[tex]h = \frac{4}{n}[/tex]
Step-by-step explanation:
Isolate the variable by dividing each side by factors that do not contain the variable.
Hence, you get the following answer:
[tex]h = \frac{4}{n}[/tex]
A cookie delivery company charges $0.90 per cookie plus a $3 delivery fee. If an
order costs $11.10, how many cookies were ordered?
Answer:
9 cookies
Step-by-step explanation:
The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.

Mariah had 2 2/4 bags of soil to use in her garden. After her gardening she had 3/4 of a bag left. How much soil did she use?
Answer:
[tex]\frac{7}{4}[/tex] of a bag of soil
Step-by-step explanation:
Given: Mariah had [tex]2\frac{2}{4}[/tex] bags of soil to use in her garden. After her gardening, she had [tex]\frac{3}{4}[/tex] of a bag left
To find: quantity of soil used.
Solution:
Quantity of soil in the garden = [tex]2\frac{2}{4}=\frac{10}{4}[/tex] bags of soil
Quantity of soil left = [tex]\frac{3}{4}[/tex] of a bag
Quantity of soil used [tex]=\frac{10}{4}-\frac{3}{4}=\frac{7}{4}[/tex] of a bag of soil.

the number of gallons of fuel for Store A and n is the number of containers of fuel at
Store B
The domain of c(n) = 4n is all real numbers.
For each store, drag all the additional restrictions needed on values of n for cín) to
model each situation
Answer:
store a- numbers greater than or equal to zero
store b-numbers greater than or equal to zero and integer values only

Solve the system by substitution:
3x + 2y = 26
Y=x + 3
Answer:
x = 4
Step-by-step explanation:
3x + 2y = 26
y = x + 3
Plug in the equation for y
3x + 2(x + 3) = 26
Multiply the 2 with what is in the parantheses
3x + 2x + 6 = 26
Combine like terms and solve for x
5x + 6 = 26
5x = 20
x = 4
Answer
x=4, Y=7
Step-by-step explanation:
3x + 2y = 26
Y=x + 3
3x+2(x+3)=26
3x+2x+6=26
5x=20
x=4
Y=4+3
Y=7
Check
3(4)+2(7)=26
12+14=26

Step-by-step explanation:
60 people were asked the colour of their car and the pictogram shows the results.
a) 16 cars are red. Complete the key.
b) How many cars are silver?
KEY: One circle represents __ cars
Red = 4 circles
White = 3 circles and a half
Silver = 5 circles and 3/4
Grey = 1 circle and 3/4
The number of silver cars in the pictogram is 23.
How many cars are silver?If 16 cars are red, then, each circle represents 4 cars.
If each circle represents 4 cars, then, each quarter of a circle represents 1 car
White car = 4 + 4 + 4 + 2
= 14 cars
Silver = 4 + 4 + 4 + 4 + 4 + 3
= 23 cars
Grey = 4 + 3
= 7 cars
Total cars = red + white + silver + grey
= 16 + 14 + 23 + 7
= 60 cars
It can therefore be concluded that silver cars is 23 in number.

I need to find the missing angle measures.
Answer:
step 1. b = 102° (vertical angles)
step 2. one complete revolution equals 360°
step 3. a + b + c + 102 = 360
step 4. a + 102 + c + 102 = 360
step 5. a + c = 156°
step 6. 2a = 156 (vertical angles are equal)
step 7. a = 78°, c = 78°.

Akira is folding a piece of paper that is 0.2 millimeters thick in half. The thickness of the paper doubles with each fold. Let n represent the fold number and t(n) represent the thickness of the paper. Which exponential function represents this scenario?
Answer:
t(n)= 0.2 * 2ⁿ
Step-by-step explanation:
Thickness= 0.2 millimeters
paper = 1
n= number of folds
The exponential function will be given by
t(n)= 0.2 * 2ⁿ
so if there's a single fold
t(1)= 0.2 * 2¹
t(1)= 0.4 mm
Now for 2 folds the thickness will be
t(2) = 0.2 *2 ²
t(2)= 0.2 *4
t(2) = 0.8mm
The exponential that represents this scenario is
t(n)= 0.2 * 2ⁿ
And for 3 folds the thickness will be
t(3) = 0.2 *2 ³
t(3)= 0.2 *8
t(3) = 1.6 mm
