Answer:
The Answer is A I'm positive
Answer:
The answer is option AStep-by-step explanation:
[tex] \frac{2}{3} x - 1 = 4 \\ [/tex]
Move 1 to the other side of the equation
That's
[tex] \frac{2}{3} x = 4 + 1 \\ \frac{2}{3} x = 5[/tex]
Multiply through by 3 to eliminate the fraction
We have
[tex]3 \times \frac{2}{3} x = 5 \times 3 \\ 2x = 15[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{15}{2} \\ [/tex]
We have the final answer as
[tex]x = \frac{15}{2} \\ [/tex]

1) On a road map, the distance from Louisville to St. Louis is 12 cm. If the map has
a scale of 2 cm = 20 miles, what is the distance to St. Louis?
120 miles.
All you have to do to understand this problem is the relationship between the cm and mi.
In this case:
2cm =20mi.
The relationship is times 10, because 2 x 10=20
So multiply 12 by 10, and you will get 120mi.
Therefore, the answer is 120mi.

what is the distance between -3/7 and 2/8
Answer:
[tex] \frac{19}{28} [/tex]
Step-by-step explanation:
distance between -3/7 and 2/8
[tex] = \frac{2}{8} - \bigg( - \frac{3}{7} \bigg) \\ \\ = \frac{2}{8} + \frac{3}{7} \\ \\ = \frac{2 \times 7}{8 \times 7} + \frac{3 \times 8}{7 \times 8} \\ \\ = \frac{14}{56} + \frac{24}{56} \\ \\ = \frac{14 + 24}{56} \\ \\ = \frac{38}{56} \\ \\ = \frac{19}{28} [/tex]

For the graph closed circle on 8 with the shading going to to left
Step-by-step explanation:
-2x+6≥3x-34 (given)
Subtract 6 on both sides
-2x≥3x-40
Subtract 3x on both sides
-5x≥-40
Divide by -5 on both sides
x≤8

(6a-3)=(7b-10)
Answer:
for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]
Step-by-step explanation:
For A
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]6a-3+3=7b-10+3[/tex]
[tex]6a=7b-7[/tex]
[tex]\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}[/tex]
[tex]a=\frac{7b-7}{6}[/tex]
For B
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]7b-10=\left(6a-3\right)[/tex]
[tex]7b-10=6a-3[/tex]
[tex]7b-10+10=6a-3+10[/tex]
[tex]7b=6a+7[/tex]
[tex]\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}[/tex]
[tex]b=\frac{6a+7}{7}[/tex]
You are researching the average emails received per day. You want to know how many employees you should survey if you want to know, at a 90% confidence level, that the sample mean emails per day is within 47 emails of the true mean emails per day. From above, we know that the population standard deviation is 155, and z-value is 1.645$_
Answer:
The value is [tex]n =29 \ employees [/tex]
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
[tex]n = [ \frac{z * \sigma }{E} ]^2[/tex]
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for [tex] \sigma[/tex]
[tex]n = [ \frac{1.645 * 155 }{47} ]^2[/tex]
=> [tex]n =29 \ employees [/tex]
find the number of possible positive real zeros of f(x)= -7x^4+ 49x^3+ 84x^2.

Thirteen less than twice a number is fifteen. What is the equation? What is the number?
Hi there!
Let the unknown number be c.
Twice a number means we multiply that number by 2:
2c
Now, subtract 13:
2c-13
This expression is equal to 15:
2c-13=15
As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.
Now, let's solve it for c.
2c=15+13
2c=28
c=14
Hope everything is clear :-)

The formula A=lw gives the
area A of a rectangle with
length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?
Answer:
78 ft^2
Step-by-step explanation:
A = lw
l = 13 ft
w = 6 ft
A = 13ft x 6 ft
A = 78 ft^2
Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.
