Explanation:
-Postcards = P
-large envelope = E
14p + 5e = 12 or 5e = 12 -14 p
10p + 15e = 24.8
5e = 12 - 14 p multiply by 3
15e = 36- 42 p
Combine 10p + 15e = 24.8 and 15e = 36- 42 p
That equals 10p + 36 - 42p = 24.8
10p + 36 - 42p = 24.8
11.2 = 32 p
P = 0.35
Bring down the equation 5e = 12 - 14p and substitute
5e = 12 - 14p
5e = 12 - (14 x 0.35)
5e = 12 - 4.90
5e = 7.10
e = 1.42

Answers
Answer:
45/7 rounds
6 3/7 rounds
Step-by-step explanation:
Here is the full question
Nicole is playing a video game where each round lasts 7/12 fraction of an hour. She has scheduled 3 3/4 fraction hours to play the game. How many rounds can Nicole play? rounds
Number of rounds she can play = total time she has scheduled / length of each round
length of each round = 7/12
total time she has scheduled = 3 3/4
3 3/4 ÷ 7/12
3 3/4 x 12/7
convert to the total time scheduled to an improper fraction
to convert to improper fraction, take the following steps :
Multiply the whole number (3) by the denominator (4) = 3x 4 = 12 Add the numerator to the answer gotten in the previous step = 14 + 3 = 15 divide the number gotten in the previous step by the denominator = 15/4[tex]\frac{15}{4}[/tex] × [tex]\frac{12}{7}[/tex] = [tex]\frac{45}{7}[/tex] rounds or [tex]6\frac{3}{7}[/tex] rounds

PLZZZZZ HELPPPP!!!! i'm very confused on what to do !!!! what is the length of the apothem of a regular hexagon with 16cm side lengths round to the nearest tenth
Answers
Answer:
A = 4.6 cm
Step-by-step explanation:
Here, we want to find the length of the apothem, given the side lengths
Mathematically, we have this as;
A = s/2 tan (180/n)
where in this case;
s is the length of the sides which is 16 cm
n is the number of sides (since it is hexagon, we have this as 6)
Substituting these values;
A = 16/2 * tan (180/6)
A = 8 * tan 30
A = 4.62
To the nearest tenth, A is 4.6 cm

What is 10z when z = 0.8
Plssss help mee
Answers
Answer:
Value of 10z = 8
Step-by-step explanation:
Given:
Equation of variable;
10z
and value of z = 0.8
Find:
Value of 10z
Computation:
We know that in given equation 10z
10 is constant(fixed value) and z is variable(changeable value)
where value of variable z is given 0.8
So,
By putting value of variable z in given equation
⇒ 10z
⇒ 10(0.8)
by multiplying variable and constant
Value of 10z = 8

Y = -2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write down the solution in (x, y) corn.
Answers
Answer:
(- 2, 2 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 2x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 2x - 2 ( add 2x to both sides )
3x + 4 = - 2 ( subtract 4 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Substitute x = - 2 into either of the 2 equations abd evaluate for y
Substituting into (1)
y = - 2 + 4 = 2
solution is (- 2, 2 )
