Answer:
A and D and E
Step-by-step explanation:
Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent

Answer:
A, D, EStep-by-step explanation:
Given expressions:
3(2t + 5) and 6t + 153(2t + 5) = 3(2t) + 3(5) = 6t + 15, the expressions are equivalentThe value of both expressions when t=3 is 33.
6*3 + 15 = 18 + 15 = 33CorrectThe value of both expressions when t=3 is 23.
IncorrectThe value of both expressions when t=6 is 41.
6*6 + 15 = 36 + 15 = 51IncorrectThe value of both expressions when t=6 is 51.
CorrectThe two expressions are equivalent.
CorrectThe two expressions are not equivalent.

2 (x + 3 )= -x
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
x = -2
Step-by-step explanation:
2 (x + 3) = -x
2x + 6 = -x
- 6 -6
2x = -x - 6
+x + x
3x = -6

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Ryan buys some jumpers to sell on a stall. He spends £130 buying 80 jumpers. He sells 75% of the jumpers for £9 each. He then puts the rest of the jumpers on a Buy one get one half price offer. He manages to sell half the remaining jumpers using this offer. How much profit does Ryan make?
Answer:
£477.5
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Total jumper bought = 80
Total spends = £130
Now, first sell 75% of jumper for £9 each, then
75% × 80 = 60
So, 60 × £9 = £540
Remaining jumper = 80 - 60 = 20
Selling half of remaining, 20÷ 2 = 10
Selling 10 jumper = (5 × £9) + (5 × £4.5 ) ( buy one get one half price)
Income of 10 = £45 + £22.5 = £67.5
So, total income by selling 70 jumpers = £540 + £67.5 = £607.5
Hence, Profit = £607.5 - £130
= £477.5
Find the zeros of the function.
Enter the solutions from least to greatest.
g(x) = -10x2 + 490
lesser =
greater x =
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

what is the percent decrease of 2,400 to 2,100?
#You times it with ×100 to get the percentage
#Part of the number/total number
2400 - 2100 = 300
300/2400 × 100 = 12.5%
So the percentage decreased is 12.5%

Find the mZNPI
Exterior angles of triangle
Given:
The figure of a triangle.
To find:
The exterior angle of the triangle m∠NPI.
Solution:
According to the exterior angle theorem, value of exterior angle of a triangle is equal to the sum of the opposite interior angles.
Using the exterior angle theorem, we get
[tex]m\angle NPI=65^\circ+78^\circ[/tex]
[tex]m\angle NPI=143^\circ[/tex]
Therefore, the measure of angle NPI is 143 degrees.

The width of a rectangle is the length minus 6 units the area of the rectangle is 27 units
Answer:
length = 9 units
Step-by-step explanation:
l = length
n - 6 = width
A = n(n - 6)
A = n² - 6n
27 = n² - 6n
n² - 6n - 27 = 0
(n + 3)(n - 9) = 0
n = -3, n = 9
length must be 9 because it cannot be a negative value

A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?
Let's assume the no. of chocolate pastry bought = x
and the no: of fruit pastry bought = y
➣ Cost of 1 chocolate pastry = Rs 26
➣ Cost of x chocolate pastry = Rs 26x
➣ Similarly, cost of fruit pastry = Rs 18 y
➣ It is given that the total cost = Rs 500
Therefore, Rs 26x + Rs 18 y = Rs 500
If we assume x = 4 and y = 22 , then
26 x 4 + 18 X 22 = Rs 500
104 + 396 = 500
⇝ No. of chocolate pastries bought = 4 ✔
⇝ No. of fruit pastries bought = 22 ✔
