The value of y varies directly with x. If x=6, then y=21
.
Find the value of x when y=70
Answer:
Direct proportionality
If the value of y varies directly with x, the value of x when y=70 is 20.
Given that, the value of y varies directly with x.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
We know that, the value of y varies directly with x
y ∝ x
⇒ y = kx
⇒ k = y/x
⇒ k = 21/6
⇒ k = 7/2
So, k = y/x
7/2 = 70/x
⇒ 1/2 = 10/x
⇒ x = 20
Therefore, if the value of y varies directly with x, the value of x when y=70 is 20.

what is 5/6 rounded to the nearest hundredth?
Answer:
0.83
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
5 / 6 = 0.833
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 833
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 5/6 (or 0.833) rounded to the nearest hundredth in decimal format is:
0.83
Find the value of x that makes m ∥ n.
Answer:
x=60
Step-by-step explanation:
X+2x=180degree because it is co interior angle
3x=180
X=180/3
X=60.
Verification
X+2x=180
60+2(60)=180
60+120=180

Answer:
Wal-mart
Step-by-step explanation:
you only get a discount from National Tire and Battery after you purchase 4 tires, which is not as good a deal as Wal-mart's
Answer:
Wal-mart.
Step-by-step explanation
20% of 225 is 45, therefore we subtract 45 from 225 and get 180.
180x4=$720
$720 is the least amount of money spent on 4 tires :)
What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (5, 6) into the partial equation
6 = 10 + c ⇒ c = 6 - 10 = - 4
y = 2x - 4 ← equation of line
Two more than a certain membership is 15 less than twice the number

The ratio of girls to boys in Liza's classroom is 5 to 4.
How many girls are in her classroom if there is a total of 27 students?
Hi!
The answer is: 15 girls.
__________________________________________________________
Let
x-----> the number of girls
y-----> the number of boys
we know that
- x+y=27, Which is equation A.
- x/y = 5/4
- isolate the variable y
- y=4/5x, Which is equation B.
- 9/5x=27
- x=5x27/9
- 15 Girls.

Cole went to the store and bought pants and shirts. He bought a total of 12 items and paid $234. If Pants cost $22 and Shirts cost $16, how many of each did he buy?
Select two equations that could be used to determine the number of pants (p) and shirts (s) Cole purchased
Answer:
Cole bought 7 pants and 9 shirts.
Step-by-step explanation:
Let p represent the number of pants and s represent the number of shirts.
Then using the provided data two equations can be formed.
p + s = 12...(i)
22p + 16s = 234...(ii)
Solve (i) and (ii) simultaneously.
Multiply (i) by 16 and subtract the resultant equation from (ii) as follows:
16p + 16s = 192
-22p - 16s = -234
-6p = -42
p = 7
Substitute p = 7 in (i) and solve for s as follows:
p + s = 16
7 + s = 16
s = 9
Thus, Cole bought 7 pants and 9 shirts.

Which of the following is the correct equation of the line that is parallel to y=−1x−5, and has a y-intercept at (0,1)?
y=−1x+0y is equal to negative 1 x plus 0
y=1x+5y is equal to 1 x plus 5
y=−1x+1y is equal to negative 1 x plus 1
y=5x−1
Answer:
The answer is option 3.
Step-by-step explanation:

Name an object that could be about the same length as each measurement. A. 4 inches b. 6 feet c. 1 meter d. 5 yards a. 6 centimeters b. 2 millimeters c. 3 kilometers
Answer and Step-by-step explanation:
A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.
B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.
C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.
D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example
E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.
F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long
G. 3 kilometers: one kilometer is 39370.079 inches hence a kilometer is bigger than inches, meter, feet, yards, centimeters, millimeters. A very big tree could be 3 kilometers long
