measure 1 and measure 2 are supplementary. if measure 1 equals (3x - 17) degrees in measure angle two equals (5x + 21) degrees find the value of x​

Answers

Answer 1

Answer:

x = 23 degrees

Step-by-step explanation:

Supplementary angles add up to 180 degrees.  Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.  

Combining like terms, we get 8x - 4 = 180, or 8x = 184.

Dividing both sides by 8 yields   x = 184/8 = 23 = x (measured in degrees)

How much solutions does this equation have?
2x+y=3
2y=-4x+6

pls answer,, show ur work, have a great day :)) !!

Answers

Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Answers

A) 2o+5l=2.75
-2o-9l = -4.15

l= 0.35

2o+5(0.35)=2.75
2o+ 1.75= 2.75
2o=1

Answers

Answer:

1/18

Step-by-step explanation:

Answer:

1/18

Step-by-step explanation:

When dividing a fraction with another number or fraction you always do the reciprocal of the second number and it turns into multiplication.

so it'll look like this:  [tex]\frac{1}{9} *\frac{1}{2}[/tex]

then you just multiply straight across to get 1/18 because 1*1 is still 1 and 9*2 is 18

Scott makes and sells bracelets. He spends $28 on supplies, and he sells
each bracelet for $6. Write an expression that represents his profit for
selling b bracelets.

Answers

Hi there,

Recall how each bracelet sells for 6 dollars.

Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.

Profit is the actual amount of money that is earned after you subtract expenses from the total sales.

For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is [tex]100-25=75[/tex].

In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.

Hence, the expression for the profit is: [tex]6b-28[/tex]

Hope that helps.

What is the mass of 2.5 moles of carbon dioxide?

Answers

Answer:

110 grams

Step-by-step explanation:

CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).

So first finding the mass of 1 molecule of CO2 which is equals to

= mass of 1 carbon atom + masses of 2 oxygen atom, we get

= 12+(16*2)= 12+32= 44 a.m.u.

Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )

1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams

So our answer is 110 grams.
