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.

Answer:
Step-by-step explanation:
Remark
Simple answer: you can't. I mean that you can't try to use 4 numbers, but you can solve the problem. You are going to have to redraw the diagram on another sheet of paper. Follow the directions below.
Directions for diagram extension.
Go to the right hand end of the 10 unit line.
Draw a line from the intersection point of the 10 unit line and 12 unit line
Draw this line so it is perpendicular to the 18 unit line. That will mean that the new line is parallel (and equal) to x
Mark the intersect point of the new line and the 18 unit line as B
Mark the intersect point of the 18 point line and the 12 unit line as C
Given and constructed
BC = 18 - 10 = 8
BC is one leg of the Pythagorean triangle.
The new x is the other leg of the Pythagorean triangle.
12 is the hypotenuse.
Formula
x^2 + 8^2 = 12^2
x refers to the new x which is equal to the given x
Solution
x^2 + 64 = 144 Subtract 64 from both sides
x^2 +64 - 64 = 144-64 Combine
x^2 = 80 Break 80 down.
x^2 = 4 * 4 * 5 Take the square root of both sides
x = 4*sqrt(5)
Comment
If you want the area it is 4*sqrt(5)(10 + 18)/2 = 56*sqrt(5)
8x+10x-4+2x+20=
(8x+10x+2x)+20-4=
20x+16=
4(5x+4)
If I remember correctly parallelograms have two pairs of parallel lines equal to each other
So 5y-20=2y+25
Solve for y
3y=45
y=15
The answer is y=15
Remember order of operations
PEMDAS which stands for
Parenthasees (or grouping symbols)
Exponents (square roots are also exponents, remmeber that)
Multiplication or Division, whichever comes first (remember, division is multiplication by a fraction
Addition or Subtraction, whichever comes first (subtraction is additon of a negative)
so
8-6*4+10/2=
no parenthases or exponents so multiply
-6*4=-24
we get
8-24+10/2
now divide
10/2=5
now we get
8-24+5
doesn't matter wha torder we do
-16+5
-11
