Answer:
3+4p+8t
Step-by-step explanation:
We have been given an expression:
3+2(2p+4t)
We will simplify the equation:
Firstly, we will open the parenthesis by multiplying it with the 2 given outside of the parenthesis we get:
3+4p+8t
Since, we have two variables so it can not be further solved therefore,
This is the maximum simplification of the given expression.
1.19p+3.18≤10.00 can be used to determine the pounds of peaches Albert can buy.
Step-by-step explanation:
Given,
Cost of one pomegranate = $1.59
Cost of two pomegranate = 1.59*2 = $3.18
Cost of peaches per pound = $1.19
Cost of p pounds of peaches = 1.19p
Total amount of spent = $10.00
Cost of p pounds of peaches + Cost of two pomegranates ≤ Total to spend
1.19p+3.18≤10.00 can be used to determine the pounds of peaches Albert can buy.

Sean reads 60 minutes on wednesday
<em><u>Solution:</u></em>
Given that,
Let "x" be the number of minutes read on monday
Let "y" be the number of minutes read on tuesday
Let "z" be the number of minutes read on wednesday
<em><u>He reads 3 times as many minutes on Tuesday as he does on Monday</u></em>
Number of minutes read on tuesday = 3 times the number of minutes read on monday
y = 3x --------- eqn 1
<em><u>He reads 4 times as many minutes on Wednesday as he does on Monday</u></em>
Number of minutes read on wednesday = 4 times the number of minutes read on monday
z = 4x ------- eqn 2
<em><u>Sean reads 45 minutes on Tuesday</u></em>
y = 45
<em><u>Substitute y = 45 in eqn 1</u></em>
45 = 3x
x = 15
<em><u>Substitute x = 15 in eqn 2</u></em>
z = 4(15)
z = 60
Thus he reads 60 minutes on wednesday
Answer:
all in all it's y=x
Step-by-step explanation:
A (4,1); B (0,-2)
G=delta y
--------
delta x
1-(-2)
-------
4-0
3/4=G
3/4=y-1/x-4
4 (y-1)=3 (x-4)
4y-4=3x-12
4y=3x+4-12
y=3/4x-3
Answer: She should choose Elite cars because its $6 cheaper than Cars 4 hire.
Working out:
1) Elite Cars:
(0.30 x 80) + 25
= 24 + 25
= $49
2) Cars 4 Hire:
(0.25 x 80) + 35
= 20 + 35
= $55
