Answer:
w = 2.5
Step-by-step explanation:
6cm * wcm = 5cm * 6cm / 2; divide both sides by 6cm
wcm = 5cm / 2; calculate
wcm = 2.5cm; divide both sides by 1cm ;)
w = 2.5
The value of w is 2.5 cm.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We are given that the triangle and the rectangle have the same area.
Therefore,
Area of triangle = Area of rectangle
6cm x w cm = 5cm x 6cm / 2;
Now divide both sides by 6cm;
w cm = 5cm / 2
Then calculate;
w cm = 2.5cm
Now divide both sides by 1 cm;
w = 2.5
Therefore, the value of w is 2.5 cm.

Mel Ting sells half-gallons of frozen yogurt for $5 each and gallons for $9 each. One day Mel sells a total of 40 containers of yogurt, for a total of $248. How many of each kind of container did Mel sell?
Answer:
Number of half-gallons containers of frozen yogurt = 28
Number of containers containing 1 gallon of frozen yogurt = 12
Step-by-step explanation:
Let [tex]x[/tex] denotes number of half-gallons containers of frozen yogurt and [tex]y[/tex] denotes number of containers containing 1 gallon of frozen yogurt.
[tex]x+y=40\,\,\,...(i)\\5x+9y=248\,\,\,...(ii)[/tex]
Multiply (i) by 5
[tex]5x+5y=200\,\,\,...(iii)[/tex]
Subtract (iii) from (ii)
[tex](5x+9y)-(5x+5y)=248-200\\5x+9y-5x-5y=48\\4y=48[/tex]
[tex]y=\frac{48}{4}=12[/tex]
Put [tex]y=12[/tex] in (i)
[tex]x+12=40\\x=40-12\\x=28[/tex]

1. A) There are 16 pieces of fruit in a bowl and 8 of them are
oranges. What percentage of the Fruit are oranges? (Please explain)
Answer:
If there are 16 pieces of fruit and 8 of them are oranges then 16 - 8 = 8. This proves that 8 is half of 16 so the percentage of oranges in the bowl is 50%
I hope this helps (:
Answer:
50% of them are oranges.
Step-by-step explanation:
Half of the fruit in the bowl are oranges and the other half aren't. As a percentage, 50% would describe the oranges in the bowl and 100% would describe the overall amount of fruit in the bowl since half of 16 is 8. Sorry if my explanation is confusing.

Answer:
B) x = 4
Step-by-step explanation:
Perhaps angles A and D are adjacent, so have a sum of 180°.
133° + (3x +35)° = 180°
3x +168 = 180 . . . . . . . . simplify
x + 56 = 60 . . . . . . . . . . divide by 3
x = 4 . . . . . . . . . . . . . . . . subtract 56

HELP ME PLSSS! Please help me...
Answer:
Expression
An algebraic expression is a combination of variables, numbers, arithmetic operations, powers, roots, and more. Within algebra, there are many forms of expressions that may have specific names, such as polynomials. Below are a few examples of algebraic expressions:
x + 7
x2 + 3x + 4
Evaluating expressions
Expressions can be part of equations, or they can also be evaluated for a given value. This means to substitute the given value into the expression then perform the operations in the expression.
Examples
1. Evaluate the following expression given that x = 5
(2x + 7) × x
(2(5) + 7) × 5 = (17) × 5 = 85
Another way that this problem could have been posed is using the following notation:
[(2x + 7) × x] | x = 5
The vertical bar means to evaluate the expression given what comes after the bar.
2. (2x2 + 7x) | x = 5
2(5)2 + 7(5) = 50 + 35 = 85
From the above examples we can see that:
(2x + 7) × x = 2x2 + 7x
They are equivalent expressions.
Equivalent expressions
Equivalent expressions are expressions in which for some given variable (or variables), such as x, the values of the expressions are equal.
2x + 2 = 2(x + 1)
For any value of x, the expressions above have the same value; they are just in different forms. We can test this by plugging a few values in for x.
If x = 1: 2(1) + 2 = 2(1 + 1)
4 = 4
If x = -5: 2(-5) + 2 = 2(-5 + 1)
-8 = -8
We can do this for many more numbers, but the result will be the same.
Writing expressions in different but equivalent forms can be helpful in certain mathematical contexts, including solving equations in algebra. Having a factored, equivalent form of an expression is one commonly used method for solving algebraic equations involving variables raised to a power.
Example
Solve 2x + 2 = (x + 1)(x + 7)
Expand the right side of the equation, then group the like terms:
2x + 2 = x2 + 8x + 7
x2 + 6x + 5 = 0
Factor the left side of the equation to find an equivalent expression:
x2 + 6x + 5 = (x + 1)(x + 5) = 0
Now that the equation is factored, we can solve for x by dividing each term and setting the remainding term equal to 0. Note that we must do this for each term or we would lose one of the solutions to the problem.
x + 1 = 0
x = -1
and
x + 5 = 0
x = -5
Therefore, the solutions to the above equation are x = -1 and x = -5
