Answer:
x = -3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
6x - 11 = 12x +7
6x - 12x = 7 + 11
-6x = 18
x = -3

1. What is the surface area of a rectangular prism with a height of 8 feet, a width of 3 feet, and a length of 4 feet?
288 ft2
160 ft2
136 ft2
264 ft2
Answer:
136 ft^2
Step-by-step explanation:
Surface area = 2 [ (l*w) + (l*h) + (w*h) ]
= 2 [ (8*3) + (8*4) + (4*3) ]
= 136 ft^2
Kyndal wants to buy a lamp that
originally cost $82, but went on sale for
20% off. The store is having an
additional sale that is 40% off the sale
price. What is the price of the lamp?
Answer:
$39.36
Step-by-step explanation:
Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82
82x0.8= 65.6
Since there is a additional 40% off multiply by 0.4 to get the discount amount
65.6x0.4= 26.24
Subtract the discount from the price
65.6-26.24= 39.36
The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Sammy won 40 bouncy balls at the fall festival. Later, she gave two to each of her friends. She has 8 remaining. How many friends did she give the balls to.
Answer:
Sammy would have 16 friends.
Step-by-step explanation:
Let total number of friends be x, each friend gets 2 balls, this can be denoted as 2x balls.
The final relation can be expressed as:
40 (total number) =2x+8 , here 8 is the remainder after distribution.
Now we can solve for x
40=2x+8
40−8=2x
32=2x
x=16
Answer:
16 friends
Step-by-step explanation:
40 balls - 8 remaining = 32 balls in total
32 b in total / 2 balls each = 16 friends

a box of breakfast tacos coat $12 and a contains 8 tacos how much dose each taco coast
Answer:
$1.50
Step-by-step explanation:
12/8 = 1.50
Answer:
each taco cost $1.50
Step-by-step explanation:
12÷8=1.501). What are the vertices of the hyperbola whose equation is:
( y + 6 ) ² ( x + 8 ) ²
_____ - _____
81 49
2). What are the foci of the hyperbola whose equation is:
( x - 6 ) ² ( y + 7 ) ²
_____ - _____
16 9
Answer:
1) The vertices of the hyperbola are (-8, -15), (-8, 3)
2) The foci of the hyperbola are (11, -7) or (1, -7)
Step-by-step explanation:
1) The vertices of a hyperbola given in the form [tex]\dfrac{\left (y - k\right)^2}{a^2} -\dfrac{\left (x - h\right)^2}{b^2} = 1[/tex] is (h, k ± a)
Therefore, for the given hyperbola with the following equation;
[tex]\dfrac{\left (y + 6\right)^2}{81} -\dfrac{\left (x + 8\right)^2}{49} = 1[/tex], we have;
[tex]\dfrac{\left (y + 6\right)^2}{9^2} -\dfrac{\left (x + 8\right)^2}{7^2} = 1[/tex]
Therefore the vertices are;
(-8, -6 ± 9) = (-8, -15), (-8, 3)
2) The equation of the given hyperbola is presented as follows;
[tex]\dfrac{\left (x - 6\right)^2}{16} -\dfrac{\left (y + 7\right)^2}{9} = 1[/tex]
The given hyperbola is of the form;
[tex]\dfrac{\left (x - h\right)^2}{a^2} -\dfrac{\left (y - k\right)^2}{b^2} = 1[/tex]
We get;
[tex]\dfrac{\left (x - 6\right)^2}{4^2} -\dfrac{\left (y + 7\right)^2}{3^2} = 1[/tex]
The foci is then (h ± c, k)
Therefore, by comparison, the foci of the given hyperbola is (6 ± c, -7)
Where c² = a² + b²
∴ c² = 4² + 3² = 25
c = √25 = 5
∴ The foci; (6 ± 5, -7) = (11, -7) or (1, -7).

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.
Answer:
13 miles
Step-by-step explanation:
Given that he traveled in a straight line to each destination. Then,
i. distance from his home to soccer field = [tex]\sqrt{x^{2} + y^{2} }[/tex]
= [tex]\sqrt{4^{2} + 3^{2}}[/tex]
= [tex]\sqrt{16 + 9}[/tex]
= [tex]\sqrt{25}[/tex] = 5 miles
ii. The distance from soccer field to the library = 8 miles.
So that we can say that;
Ryan's total distance from home to the library = 5 + 8
= 13 miles
Thus, Ryan would have traveled 13 miles by the time he reached the library.

Step-by-step explanation:
HCF of 225 and 270 is?
Answer:
I believe it's 45
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
270 = 1*225 + 45
225 = 5 * 45 + 0
HCF = 45
The above is Euclid's method for finding the HCF.
The other method is by finding the prime factors:
225 = 3 * 3 * 5 * 5
270 = 2 * 3 * 3 * 5
We pick out common factors:
So the HCF 3 * 3 * 5
= 45.

Find the area of the regular polygon.
10
5 divided by 3
Answer:
Start by setting it up with the divisor 3 on the left side and the dividend 105 on the right side like this:
3 ⟌ 1 0 5
Step 2:
The divisor (3) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
3 ⟌ 1 0 5
Step 3:
Multiply the divisor by the result in the previous step (3 x 0 = 0) and write that answer below the dividend.
0
3 ⟌ 1 0 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
3 ⟌ 1 0 5
- 0
1
Step 5:
Move down the 2nd digit of the dividend (0) like this:
0
3 ⟌ 1 0 5
- 0
1 0
Step 6:
The divisor (3) goes into the bottom number (10), 3 time(s). Therefore, put 3 on top:
0 3
3 ⟌ 1 0 5
- 0
1 0
Step 7:
Multiply the divisor by the result in the previous step (3 x 3 = 9) and write that answer at the bottom:
0 3
3 ⟌ 1 0 5
- 0
1 0
9
Step 8:
Subtract the result in the previous step from the number written above it. (10 - 9 = 1) and write the answer at the bottom.
0 3
3 ⟌ 1 0 5
- 0
1 0
- 9
1
Step 9:
Move down the last digit of the dividend (5) like this:
0 3
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
Step 10:
The divisor (3) goes into the bottom number (15), 5 time(s). Therefore put 5 on top:
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
Step 11:
Multiply the divisor by the result in the previous step (3 x 5 = 15) and write the answer at the bottom:
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
1 5
Step 12:
Subtract the result in the previous step from the number written above it. (15 - 15 = 0) and write the answer at the bottom.
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
- 1 5
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.

Find the value of sin^-1(4pi/5)
Answer:
No value because 4π/5 exceeds the domain
Step-by-step explanation:
The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]
Since 4π/5>1, this exceeds the domain and therefore has no value.

For problems 11 and 12, find the area of the figure. Round your answer to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
11)
A= (B x H)/2
A= (2.9x3.2)/2= 4.64cm²
12)
A= (B+b)H /2
A= (12+10)5.6 /2 = 61.6in
Answer:
I think that the answer might be 9.30 for the first one and the second one I think is 670.
Step-by-step explanation:
To find the area, you have to multiply the height and width for the two figures.
3.2 × 2.9 = 9.28
12 × 10 × 5.6 = 672
I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.
