Answer:
D
Step-by-step explanation:
We can cross off a because it is impossible to have negative of a material.
Now lets get into the System of equations. First subtract both of them to have one common variable(we will find the second one later)
- P + N = 134
- P + 3.1N = 241.10
2.1N = 107.1
107.1/2.1 = 51
Now we know that n = 51
lets substitute,
P + 51 = 134
P = 83
Lets check
83 + 51 = 134

Answer:
triangles unfold into a 180 degree angle so...
Step-by-step explanation:
Alright so the two dashes in a line means they are equivalent so if I only give one final answer use it for both...
D: 180-52=128 now divide by two since equal angles so 64 degrees for the angles
E: 180-90=90, 90/2 so 45 degrees for those angles
F: okay interesting 180-130= 50 degrees so that's the inside angle there for x and y so to find z its 180- 100 which is 80 x&y is 50 while z's 80
G: 180-36=144 divide that by two and viola 72 is the answer
H: the angle of 86 is correct since mirrored. so x is 86. now for the unlisted angle 180-124= 66 so to find y 86+66=152 so 180-152=28. So x=86 y=28 and the unlisted is 66.

Write an absolute value equation that has the solutions x= -10 and x = -5
Answer:
∣x + 7.5∣ = 2.5
Step-by-step explanation:
∣x + 7.5∣ = 2.5
x + 7.5 = -2.5 OR x + 7.5 = 2.5
-7.5 -7.5 -7.5 -7.5
-------------------- ----------------------
x = -10 x = -5
As you can see, the equation ∣x + 7.5∣ = 2.5, satisfies both of the x values, x=-10 and x=-5.
The absolute value equation that has solutions x= -10 and x = -5 is | x + 7.5 | = 2.5.
What is an absolute function ?Absolute value function is always positive |x| = a implies x = a Or - x = - a
According to the given question we have to write a equation we have to write an absolute value equation that has solution x = -10 and x = - 5.
Let the absolute value be ∣x + 7.5∣ = 2.5.
∴ x + 7.5 = 2.5 OR - ( x + 7.5 ) = 2.5
x + 7.5 = 2.5
x = 2.5 - 7.5
x = - 5.
OR
- ( x + 7.5 ) = 2.5
- x - 7.5 = 2.5
- x = 2.5 + 7.5
- x = 10
x = - 10.

A bag contains 7 red discs, 5 green discs and 2 pink discs.
Helen takes one disc at random, records the colour and replaces it in the bag. She does this 140 times.
Find how many times she expects to take a green disc.
Work Shown:
5 green discs
7+5+2 = 14 discs total
5/14 is the probability of getting a green disc
(5/14)*140 = 50 green discs are expected if 140 trials are conducted.
The no. of green discs she expects by replacing and drawing again for 140 times is 50.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given A bag contains 7 red discs, 5 green discs, and 2 pink discs.
So, no. of sample space N(S) = 7 + 5 + 2 = 14.
∴ The probability of getting a green disc P(G) = N(G)/N(S).
P(G) = 5/14.
Now she replaces the discs drawn and picks one random disc from the bag again 140 times,
Therefore the probability of getting a green disc will remain the same as an independent event because of the replacement.
∴ The no. of green discs she expects is (5/14)×140 = 50 times.

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.4(5x−15)=2.5(x+3)
(0.4)(5x)+(0.4)(−15)=(2.5)(x)+(2.5)(3)(Distribute)

Answer: if the width was not effected then the width is still 24 inches
if the area stayed the same, then
find area
area=legnth times width

Vijay bought a camera that was marked down 80% from an original price of $355. If he paid 4% sales tax what was the total cost of the camera?
The total cost of the camera is $73.84
Since Vijay bought a camera that was marked down 80% from the original price of $355, then the amount paid will be:
= $355 - (80% × $355)
= $355 - (0.8 × $355)
= $355 - $284
= $71
Since there is a 4% sales tax, then the total amount paid will be:
= $71 + (4% × $71)
= $71 + (0.04 × $71)
= $71 + $2.84
= $73.84
The total cost of the camera is $73.84

−3,12,27, what is the answer
Answer:
The next term is 42
Step-by-step explanation:
Let's use Arithmetic Progression
a₁ = - 3
a₂ = 12
a₃ = 27
Now,
The Formula of Common Difference d is
d = a₂ - a₁
= 12 - (-3)
= 12 + 3
d = 15
d = a₃ - a₂
= 27 - 12
d = 15
Here, the common difference is same
aₙ = aₙ₋₁ + d
a₄ = a₄₋₁ + 15
a₄ = a₃ + 15
a₄ = 27 + 15
a₄ = 42
So, The next term is 42
