Answer:

x=6

Step-by-step explanation:

We are given the equation

7x+2y=48

We are also given y=3. Since we know y is equal to 3, we can substitute 3 in for y.

7x+2(3)=48

Multiply 2 and 3

7x+6=48

Now, we need to solve for x. To do this, we have to get x by itself. First, subtract 6 from both sides, since 6 is being added on.

7x+6-6=48-6

7x=42

Next, divide both sides by 7, because 7 and x are being multiplied. This will cancel out the 7, and leave x by itself.

7x/7=42/7

x=6

$\sqrt[n]{a^m}=a^\frac{m}{n}\\\\\sqrt[n]{a}=a^\frac{1}{n}\\\\(a^n)^m=a^{nm}\\\\(a\cdot b)^n=a^n\cdot b^n\\\\(27x^{-9})^\frac{1}{3}=27^\frac{1}{3}(x^{-9})^\frac{1}{3}=\sqrt[3]{27}\cdot x^{-9\cdot\frac{1}{3}}=3x^{-3}=\dfrac{3}{x^3}$

"Journey Motorcycles produced 100 motorcycles using 50 workers who each worked 8 hours a day. Journey's productivity was 1/4." T

Burka [1]

Answer:

Yes, this is true.

Step-by-step explanation:

Given is :

50 workers each worked 8 hours a day.

Combined total is = $50\times8=400$ hours

Journey Motorcycles produced 100 motorcycles.

So, their productivity is :

$\frac{100}{400}=\frac{1}{4}$ This can be simplified as 1 motorcycle per 4 hours.

So, the given statement is true.

Make a table and graph the function Y=3x+2

Tom [10]

ANSWER

See attachment

EXPLANATION

The given function is

y=3x+2

When x=-1,

y=3(-1)+2=-1

when x=0, y=3(0)+2=2

when x=1, y=3(1)+2=5

We plot the points (-1,-1), (0,2) and (1,5) and draw a straight line through them to obtain the graph as shown in the attachment.
