Seductions
1/2 : 1/3 = x : 1
1/2 ÷ 1/3 = x / 1
1/2 × 3/1 = x/2
3/2 = x/2
x = 3/2 ÷ 1/2
= 3/2 × 2/1
= 6/2
x = 3 toothpaste

The sum of four consecutive odd integers is –72. Write an equation to model this situation, and find the values of the four integers.
A.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –23; n + 4 = –25; n + 6 = –27
B.
n + (n – 2) + (n – 4) + (n – 6) = –72; n = – 21; n – 2 = –23; n – 4 = –25; n – 6 = – 27
C.
n – (n + 2) – (n + 4) – (n + 6) = –72; n = –20; n + 2 = –18; n + 4 = –16; n + 6 = –14
D.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –19; n + 4 = –17; n + 6 = –15
Answer:
D. n+n+2+n+4+6= -72; n= -21; n+2= -19; n+4= -17; n+6= -15
There are 2 below and 2 above it.
-15, -17, -19, -21
Step-by-step explanation:
the sum of four consecutive odd integers is -72. write an equation to model this situation, and find the values of the four integers .
n + n+2 + n+4 + n+6 = -72
4n + 12 = -72
or
-72/4 = -18, the center
In a certain chemical, the ratio of zinc to copper is 3 to 13 . A jar of the chemical contains 585 of copper. How many grams of zinc does it contain?
Answer: 135 grams of Zinc
Step-by-step explanation:
The ratio of Zinc to Copper in this scenario is 3:13 and in this jar there is 585 of Copper.
Using direct proportion, the grams of Zinc in the jar is:
3 : 13
x : 585
Cross -multiplying will give:
1,755 = 13x
x = 1,755/13
x = 135 grams of Zinc

BlacIf w = -2 and v = -8, which of the following expressions shows the values correctly substituted in for the variables in the expression w2 - v + 1?
(-2) 2 - (-8) + 1
(-2) 2 - (8) + 1
-2 2 - (-8) + 1
-2 2 - 8 + 1
Answer:
-2² - (-8) + 1
Step-by-step explanation:
The values given are:
w = -2 and v = -8
Expression given:
w² - v + 1
When we substitute, we put a certain value in place of another. In an equation, variables are used as placeholders.
For this problem:
w = -2
v = -8
So;
-2² - (-8) + 1
Answer:
Given that w=-2 and v=-8
The expression is w²-v+1
Now putting the value of w=-2 and v=+8 in the given expression, we get
(-2)²-(-8)+1
Hence, (-2)²-(-8)+1 is the right answer.

Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20
