Answer:45+60=15x+15x
Step 1: Simplify both sides of the equation.
45+60=15x+15x
(45+60)=(15x+15x)(Combine Like Terms)
105=30x
105=30x
Step 2: Flip the equation.
30x=105
Step 3: Divide both sides by 30.
30x/30= 105/30
x= 7/2
Answer:
x= 7/2

9514 1404 393
Answer:
9. rhombus
10. rhombus, rectangle, square
11. rhombus
Step-by-step explanation:
9, 11. Angles are obviously not 90°, so each figure is a rhombus.
__
10. Line slopes are 1 or -1, so are perpendicular. Side lengths are all the diagonal of 6 squares, so 6√2.
The figure is a rhombus, rectangle, and square.

Which expression is equivalent to (32−−√5)13 ?
I know this is where the question is but the answer is 3 and 2/15
Answer:
the given expression is equivalent to the [tex]3 \frac{2}{15}[/tex]
Step-by-step explanation:
The computation is shown below:
[tex]3^2 \frac{1}{5} : 3 \frac{2}{5} \\\\(3\frac{2}{5})^\frac{1}{3} \\[/tex]
Now applied the exponent rule i.e. presented below:
[tex](a^b)^c = a^{bc}[/tex]
[tex]= 3 \frac{2}{5} \times \frac{1}{3} \\\\\frac{2}{5} \times \frac{1}{3} \\\\= \frac{2}{15}[/tex]
[tex]3 \frac{2}{15}[/tex]
Hence, the given expression is equivalent to the [tex]3 \frac{2}{15}[/tex]

the cable company charges a monthly fee of $45. Each movie rental is $1.99. you owe $68.88. How many movies did you rents?
Answer:
12 movies
Step-by-step explanation:
If you do not rent any vidoes you will be charged $45 no matter what, so...
Movies + 45 = total charge
each movie is 1.99 and you owe (total charge) $68.88
equation:
1.99x + 45 = 68.88
-45 -45 (subtract 45 from each side to keep equation balanced)
1.99x = 23.88 (now divide both sides by 1.99 to get x alone)
x = 12
you rented 12 movies

Investors buy a studio apartment for $180,000 . Of this amount, they have a down payment of $36,000. Their down payment is what percent of the purchase price? What percent of the purchase price would a $9,000 down payment be?
Answer:
Step-by-step explanation:
From the question, we are informed that investors buy a studio apartment for $180,000 and that they have a down payment of $36,000. The percentage of the down payment on the purchase price will be:
= 36000/180000 × 100
= 1/5 × 100
= 20%
What percent of the purchase price would a $9,000 down payment be?
This will be:
= (9000 / 180000) × 100
= 0.05 × 100
= 5%
Answer:
20%
5%
Step-by-step explanation:
Price of a studio apartment = $180,000
Down payment = $36,000
Their down payment is what percent of the purchase price?
= Down payment / Price of a studio apartment × 100
= $36,000 / $180,000 × 100
= 0.2 × 100
= 20%
What percent of the purchase price would a $9,000 down payment be?
= Down payment / Price of a studio apartment × 100
= $9,000 / $180,000 × 100
= 0.05 × 100
= 5%
Samantha donated 5 T-shirts to charity and has 16 left. Which equation could be used to find x, the number of T-shirts Samantha had originally?
A. x + 16 = -5
B. x - 5 = -16
C. x + 5 = 16
D. x - 16 = 5
Answer:
It would be D.
Step-by-step explanation:
It would be D. because if, say, x was a 5, 5-16=5, whereas all the other answers have it in the wrong order or have an addition instead of a subtraction. Hope this helps :)
A 2% solution of acid was mixed with a 12% solution to produce an 8% solution. The amount of 2% solutions is 2 liters less than the 12% solution. How much 2% solution and how much 12% solution were used to produce 10L of the 8% solution ?
Answer:
The number of liters of 2% solution of acid = x = 4 Liters
The number of liters of 12% solution = y = 6 Liters
Step-by-step explanation:
Let us represent
The number of liters of 2% solution of acid = x
The number of liters of 12% solution = y
The system of equations for the above question is given as:
x + y = 10L...... Equation 1
x = 10 - y
2% × x + 12% × y = 8% × 10L
0.02x + 0.12y = 0.8....... Equation 2
We substitute 10 - y for x in Equation 2
0.02(10 - y) + 0.12y = 0.8
0.2 - 0.02y + 0.12y = 0.8
Collect like terms
- 0.02y + 0.12y = 0.8 - 0.2
0.10y = 0.6
y = 0.6/0.10
y = 6 Liters = 6 L
Note that:
x = 10 - y
x = 10 - 6
x = 4 Liter= 4 L
Therefore:
The number of liters of 2% solution of acid = x = 4 Liters
The number of liters of 12% solution = y = 6 Liters

A kite is a quadrilateral which has 2 sides next to each other that are congruent and where the other 2 sides are also congruent. Give kite WXYZ, show that at least one of the diagonals of a kite decomposes the lite into 2 congruent triangles
Answer:
Step-by-step explanation:
Given: Kite WXYZ
Prove: That at least one of the diagonals of a kite decomposes the kite into 2 congruent triangles.
A diagonal is a straight line from one vertex to another of a given shape or figure.
Considering diagonal WY of the kite,
<WYZ ≅ <WYX (diagonal WY is the bisector of <Y)
<ZWY ≅ <XWY (diagonal YW is the bisector of <W)
WZ ≅ WX (congruent property)
YZ ≅ YX (congruent property)
Thus,
ΔWYZ ≅ ΔWYX (Angle-side-Angle congruent property)
Therefore, the given kite can be decompose into 2 congruent triangles (ΔWYZ and ΔWYX).

Divide using synthetic division
(2x^3 - 2) divided by (x - 5)
2x^2 − 10x − 202
2x^2 - 10x + 50 - 252/x-5
2x^2 + 10x + 298
2x^2 + 10x + 50 + 248/x-5
Answer:
Divide using synthetic division
Step-by-step explanation:
2x^2 − 10x − 202
2x^2 - 10x + 50 - 252/x-5
2x^2 + 10x + 298
2x^2 + 10x + 50 + 248/x-5
The Synthetic divison is (2x^(3) -2) ÷ (x-5) = 2x^(2) - 2x + 6.
What is synthetic division?Write the coefficients of the dividend in a row, placing the divisor to the extreme left of the row then Bring the first coefficient of the divisor down.
To Multiply the divisor by the number directly below it in the row and write the answer to the right of the number. Now Add the two numbers to the right of the divisor and write the answer below.
For the example given, the process is as;
(2x^3 - 2) ÷ (x - 5)
(x - 5) | 2 -10 14 -24
| -4 8 10 24
| 0 -2 6 0
| 0 0 0 0
Therefore, the quotient is 2x^(2) - 2x + 6

A fruitcake recipe calls for 2 1/3 cups of almonds and 1 3/4 cups of pecans. If Eliza would like to make 4 fruit cakes, then how many cups of nuts does she need?
Answer:
Almonds used for 4 fruitcake = 9 1/3
Pecans used for 4 fruitcake = 7 cups
Step-by-step explanation:
Recipe for 1 fruitcake:
Almonds = 2 1/3 cups
Pecans = 1 3/4 cups
If Eliza would like to make 4 fruit cakes, then how many cups of nuts does she need?
Recipe for 4 fruitcake:
Multiply each recipes by 4
Almonds = 2 1/3 cups × 4
= 7/3 × 4
= (7×4) / 3
= 28/3
= 9 1/3 cups
Almonds used for 4 fruitcake = 9 1/3
Pecans = 1 3/4 cups × 4
= 7/4 × 4
= (7×4) / 4
= 28 / 4
= 7 cups
Pecans used for 4 fruitcake = 7 cups
