What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of pineapples = 2
Amount given = £5
Amount returned = £3.60
The cost of the two pineapples.
= 5 - 3.60
= £1.40
The cost of one pineapple.
= 1.40/2
= 140/200
= 14/20
= £0.7
Thus,
The cost of one pineapple is £0.7.

Mrs. Gildner took a survey of the 30 students in her math class. Of the 30 students surveyed, 18 of them said that chocolate is their favorite ice cream flavor. 4 students listed vanilla as their favorite flavor. The remaining students indicated that strawberry is their favorite kind of ice cream.
What is the ratio of chocolate to strawberry? SIMPLIFY if possible!
Answer: 9:4
Step-by-step explanation: Total is 30. Add 18 and 4 to see how many students were already surveyed, (22) and then subtract that from 30. Then you get 8, so the ratio is 18:8. Then simplify by dividing both numbers by 2, so you get 9:4. Hope that helps :)
Lucy bought a table on sale for $665. This price was 24% less than the original price.
What was the original price?
Answer: Below
Step-by-step explanation:
24% is basically 0.24. Since we want to find the original price we make the equation:
x * (1 - 0.24) = 665
For x is the original price. Simplify:
x * (0.76) = 665
x = 665/0.76
x = 875
Our answer is 875

Convert the following equation into standard form.
[tex]y = - \frac{4x}{9} + 3[/tex]
Move the expression to the left-hand side and change its sign
[tex]y + \frac{4x}{9} = 3[/tex]
Multiply both sides of the equation by 9
[tex]9y + 4x = 27[/tex]
Use the commutative property to reorder the terms
[tex] \underline{ \underline{4x + 9y-27 = 0}}[/tex]
Standard form of a line:-
Ax+By+C=0[tex]\\ \rm\Rrightarrow y=\dfrac{-4x}{9}+3[/tex]
[tex]\\ \rm\Rrightarrow y=\dfrac{-4x+27}{9}[/tex]
[tex]\\ \rm\Rrightarrow 9y=-4x+27[/tex]
[tex]\\ \rm\Rrightarrow 4x+9y-27=0[/tex]

HELP ASAP!!!!!! 65 POINTS!!!
Answer:
CD =7.5 AC =20
Step-by-step explanation: you can answer this question by creating a proportion. For the side AB, we can find the total length by adding AE and EB, for a total of 8. Now we can build a proportion, where x equals AC. 12.5/x= 5/8. When you build a proportion, it’s important to make sure you use the same corresponding parts in the same places, for example, in both the fractions we made for the proportion, the total side length was on the bottom. From this proportion, we now cross multiply to get 5x=100. Divide both sides by 5 and you get that the length of AC is 20. We can do the same with CD. The proportion you’d use to find CD would involve the smaller line segment over the total length of the line. This would look like so: x/20=3/8. Cross multiply again and you’d get 60=8x. Divide both sides by 8 and you’d get x=7.5. This means the length of CD is 7.5.

What is an equation of the line that passes through the points (5,2) and (-5,-6) PLEASE ANSWER
Answer:
y = 4/5 x - 2
Step-by-step explanation:
Find for slope first:
m = (y2 - y1) / (x2 - x1)
= [(-6) - 2] / [(-5) - 2]
= -8/-10
= 4/5
Solve for b. Use (5, 2)
y = mx + b
2 = 4/5 (5) + b
2 = 20/5 + b
2 = 4 + b
2 - 4 = b
-2 = b
Substitute the value of m and b.
y = mx + b
y = 4/5 x + (-2)
y = 4/5 x - 2
What are the average high and low temperatures (in degrees Celsius) for Nuuk in January?
Answer:
6 degrees high/-10 degrees low
Step-by-step explanation:
Identify the value of y.
9y+6 = 3y+3+7+26
Answer:
y=5
Step-by-step explanation:
9y+6 = 3y+3+7+26
arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.
9y - 3y = 3 + 7 + 26 -6
6y / 6 = 30 / 6
Now divide both sides by 6 in order for y to be alone.
y = 5
