The perimeter of a rectangular painting is 326 centimeters. If the length of the painting is 88 centimeters, what is its width?
Answer:
The width is 75 cm
Step-by-step explanation:
Perimeter is L+L+W+W aka 2L+2W
L=length W=width
326=2(88)+2W
Solve for W
326=176+2w
150=2w
w=75
Answer:
Width = 75 cm
Step-by-step explanation:
l = 88 cm
Perimeter = 326 cm
2l +2w = 326
2*88 + 2w = 326
176 + 2w = 326
Subtract 176 from both sides
2w = 326 - 176
2w = 150
Divide both sides by 2
w = 150/2
w = 75
What is the approximate solution of the linear system represented by the graph below?
Answer: The approximate solution is
(4,-1)
Step-by-step explanation:
The point of intersection of the two lines is the solution of the linear systems represented by the graph.
From the graph we can determine that each box is 2 units.
From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be
Note that since each box is two units, half way between the boxes gives one unit.

(c) if Slope = 1/4; y-intercept= 0
y = x/4 + 0
y = x/4
4y = x
(d) if Slope= -5/2; y-intercept= -3

Stefan sells jin a bicycle for $114 and a helmet for $18. The toltal cost for jin is 110% of what stefan spent originally to buy the bike and helmet. How much did stefan spend originally? How much money did he make by selling the bicycle and helmet to jin?
Answer:
$ 12
Step-by-step explanation:
First, we'll find out how much, in total Jin spent.
114 (bicycle) + 18 (helmet) = $ 132
Now, we know she spent 110% of what Stefan did.
132 = 110% of x (the value stefan spent)
So, we want to get x, the cost, by itself. We will divide 110.
132/110(%) = x
Remember, percent is a decimal that's been moved (2 places to the right), so... (we move it 2 places to the left for a decimal)
132/1.10 = 120
Stafen originally spent $120 on the equipment. Now we subtract this amount from what Jin spent:
132 - 120 = 12
Stefan made $12 off of Jin's purchase.

[tex]y = - 8x + 8 \\ = > y = - 8( \frac{y - 2}{4} ) + 8 \\ = > y = \frac{ - 8y + 16}{4} + 8 \\ = > y = \frac{ - 8y + 16 + 32}{4} \\ = > y = \frac{ - 8y + 48}{4} \\ = > 4y = - 8y + 48 \\ = > 4y + 8y = 48 \\ = > 12y = 48 \\ = > y = 4[/tex]
[tex]y = 4x + 2 \\ = > 4 = 4x + 2 \\ = > 4x = 4 - 2 \\ = > 4x = 2 \\ = > x = \frac{2}{4} = \frac{1}{2} [/tex]

Use the Distributive Property to write an equivalent expression for 4(8 + 3).
Answer:
4 × 8 + 4 × 3
Step-by-step explanation:
4(8 + 3) =
Multiply 4 by 8 and 4 by 3 and add the products.
= 4 × 8 + 4 × 3
Using the Distributive Property, an equivalent expression for 4(8 + 3) is: 4 * 8 + 4 * 3.
How to Write Equivalent Expressions Using the Distributive Property?To use the Distributive Property, you need to distribute the number outside the parentheses to each term inside the parentheses. Here's the calculation:
4(8 + 3) = 4 * 8 + 4 * 3
Now, perform the multiplication:
4(8 + 3) = 32 + 12
Finally, add the numbers:
4(8 + 3) = 44
So, the equivalent expression for 4(8 + 3) is 4 * 8 + 4 * 3.

Is x+2 a factor of x^3+8
Explanation:
Apply the sum of cubes factoring rule to get
a^3+b^3 = (a+b)(a^2-ab+b^2)
x^3+2^3 = (x+2)(x^2-x*2+2^2)
x^3+8 = (x+2)(x^2-2x+4)
The expression x^3+8 fully factors to (x+2)(x^2-2x+4), and (x+2) is one of those factors.

Answer:
(b) Step 2 has the first error
Step-by-step explanation:
An expression like this is evaluated according to the Order of Operations. That requires expressions in parentheses be evaluated first.
In Step 1, John correctly evaluated the first part of the sum (5 -3 +4) to get (2 +4). There is no error in this step.
In Step 2, John incorrectly computes 36 ÷ 2 = 18, ignoring the incomplete evaluation of the sum in parentheses. John's first error is in Step 2.
In Step 3, John correctly accomplished the next step in evaluating the expression he got in Step 2. There is no error in this step.
In Step 4, John correctly accomplished the next step in evaluating the expression he got in Step 3. There is no error in this step.
_____
Additional comments
If the expression were correctly evaluated, the steps would be ...
Step 1: (36 ÷ (2 +4))/2
Step 2: (36 ÷ 6)/2
Step 3: 6/2
Step 4: 3
__
One could argue that steps 3 and 4 are also in error, since they propagate the error made in step 2.

Chase is making a cake for his daughter's birthday. The normal recipe
calls for 8 ounces of butter and 16 ounces of sugar. Chase then
decides to make a slightly smaller cake and only use 6 ounces of
butter. How many ourses of sugar will he need in his smaller cake?
Answer:
12 ounces of sugar
Step-by-step explanation:
According to the original recipe whatever the ounces of butter is, you multiply it by 2 to get the ounces of sugar. Therefore, 6 x 2 = 12. 12 ounces of sugar.
I would say since
6÷8 is 0.25 we are removing 25% of butter
So logically you would remove 25% of the ounces of sugar, so 16*0.25 is 4
so 16-4
12
I'd say 12 ounces of sugar
