Answer:
X is just the variable or missing edge, side, angle .etc that you are looking for
Step-by-step explanation:
The sum of two numbers is x. If one of the numbers is 12, what is the other?
a. 12 x
b. 12 - x
c. 12 + x
d. x - 12
Answer:
D
Step-by-step explanation:
The question states that the sum of two numbers is x, and they give us one number which is 12. We know that 12 + 12x cannot equal x. We also know that 12 + 12 + x = x will cancel out the variable. Then, we can eliminate B, as the questions stated that the sum of two numbers is x, and they gave us one number of x. We know that the other number will be the unknown value minus 12, because 12 + x - 12 = x will simplify into x = x, which is true.

The wavelength of violet light is 4.0 x 10^−7 m. The wavelength of red light is 6.5 x 10^−7 m. How much longer is the wavelength of red than violet?
A 2.5 × 10^–7 m
B 1.05 × 10^–7 m
C 2.5 × 10^–6 m
D 1.05 × 10^–6 m
Answer:
A 2.5 × 10^–7 m
Step-by-step explanation:
Given
wavelength of violet light = 4.0 x 10^−7 m.
The wavelength of red light = 6.5 x 10^−7 m
To find the how much longer is wavelength of red light than violet light we have to find difference of wavelength of red and violet light
Difference in wavelength of red light and violet light =
wavelength of red light -wavelength of violet light
= 6.5 x 10^−7 m - 4.0 x 10^−7 m
Difference in wavelength of red light and violet light = (6.5 - 4.0)*10^−7 m
Difference in wavelength of red light and violet light =2.5 x 10^−7 m
Thus,
wavelength of red light is 2.5 x 10^−7 m longer than wavelength of violet light

what is the slope of a line perpendicular to the line whose equation is 2x-y=-6
Answer:
m⊥ = –½
Step-by-step explanation:
First, put the given equation in slope-intercept form:
2x – y = –6
–y = –2x – 6
y = 2x + 6
The slope of the line perpendicular to the line given will be the negative reciprocal of the given line's slope, so:
If m = 2, then m⊥ = its negative reciprocal:
m · –1
2 · –1
–2 → –½
So, the negative reciprocal of 2 is –½.

Jessica prepared 36 kilograms of dough after working 6 hours. How much dough did Jessica prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answer:
48
Step-by-step explanation:
because 36 divided by 6 is 6 and that is how much dough she produces in an hour so if you added two more 6s to 6 to make it 8 meaning you are adding 12 because that is how much dough she makes in an hour

slove for x in terms of p,m, and g
m=g-px
Answer:
- (m-g)/p =x
Step-by-step explanation:
subtract g
m-g=-p(x)
divide by -p
-(m-g)/p =x
If p varies directly as
the cube of q, and p =
26 when q = 2, find p
when q = 5
Answer:
The value of p at q = 5 is 406.25
Step-by-step explanation:
∵ p varies directly as the cube of q
→ That means p ∝ q³
∴ The equation of variation is p = kq³, where k is the constant of variation
∵ p = 26 when q = 2
→ Use them to find the value of k
∵ 26 = k(2)³
∴ 26 = k(8)
∴ 26 = 8k
→ Divide both sides by 8
∴ [tex]\frac{26}{8}=\frac{k}{8}[/tex]
∴ 3.25 = k
→ Substitute it in the equation of variation
∴ p = 3.25 q³ ⇒ equation of variation
∵ q = 5
→ Substitute it in the equation of variation to find p
∴ p = 3.25 (5)³
∴ p = 406.25
∴ The value of p at q = 5 is 406.25

-4(3+7m) please help i will give brainlest and do not answer just to get points this is DUE IN FIVE MINUTES
Answer:
-28m-12
Step-by-step explanation:hope that helps :)
=(−4)(3+7m)
=(−4)(3)+(−4)(7m)
=−12−28m
=−28m−12
Answer:
-4(3+7m) = -28m - 12
Step-by-step explanation:
-4 (3 + 7m)
= -4 (3) + -4(7)
= -12 + (-28)
= -12 -28m

What does negative 3 over 5 > −2 indicate about the positions of negative 3 over 5 and −2 on the number line?
So,
Ignore the negatives and just make them positives.
For now.
Then, you look at 3/5 and say... it's 3 ticks towards the number five,
meaning it's between 4 and 5. After you do that whats happens is you place back the negatives and you have -3/5 and -2.
-2 < 5 and -2 < 4
Meaning it goes more to the left.
I could be wrong but If I'm right please mark brainliest
Use the distributive property to simplify the expression, then combine like terms -12 - 5p +2(6p+p)
Answer:
-12 + 9p
Step-by-step explanation:
Original Equation:
-12 - 5p + 2(6p + p)
Distributive property.
2 x 6p = 12p
2 x p = 2p
Equation:
-12 - 5p + 12p + 2p
Subtract 5p from 12p
-12 + 7p + 2p
Add.
-12 + 9p
Hope this helped :)

Brian, Chris, and Damien took a math test that had 20 questions. The number of questions Brian got right is 14 more than the number of questions Chris got right. Damien correctly answered 2 less than the number of questions Chris answered correctly. If Brian and Damien have the same score, which statement is true?
Answer:
C. Brian and Damien both answered 2 more questions correctly than Chris did.
Step-by-step explanation:
A. Brian and Damien both answered 2 fewer questions correctly than Chris did.
B. Brian and Damien both answered 4 more questions correctly than Chris did.
C. Brian and Damien both answered 2 more questions correctly than Chris did.
D. Brian and Damien both answered 4 fewer questions correctly than Chris did.
Let
B = number of questions Brian got right
C = number of questions Chris got right
D = number of questions Damien got right
The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right.
B = 14 + (1/4) * C
Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly.
D = (5/4) C - 2
If Brian and Damien have the same score,
14 + (1/4) * C = (5/4) C - 2
14 + 1/4C = 5/4C - 2
14 + 2 = 5/4C - 1/4C
16 = 5C-C/4
16 = 4/4C
C = 16
B = 14 + (1/4) * C
= 14 + 1/4*16
= 14 + 4
= 18
D = (5/4) C - 2
= 5/4*16 - 2
= 5*4 - 2
= 20 - 2
= 18
