Answer: e=6

Step-by-step explanation:

4e-14=10

Move constant to the right

4e=10=14

Add the numbers

4e=24

Divide both sides by 4

SOLUTION

Answer:

Step-by-step explanation:

To calculate this you would first bring -14 over. In order to bring it over you would need to change the symbol from a minus to a plus, this cancels it out on the left but brings it over on the right. Then you are left with $4e=24$ so you would divide it by 4 to find what e is equal to.

1) Bring the -14 over to the right.

$4e- 14+14=10+14\\$

Because we changed the symbol this cancels it out.

$4e=10+14$

$4e=24$

2) Then you would divide 24 by 4 to find out the answer for e.

$e=24/4$

$e=6$

Relay races called for 8 people on a team. There were 43 men and 34 women who wanted to race. How many teams could be formed ?ho

ELEN [110]

It would be an odd number of teams. What I did was add 43 and 34 together. Which gave me 77. So 77 people total wanted to race. There can only be 8 racers on each team. Each means to divide. So I divided 8 and 77. It gave me 9 with a remainder of 5. So there will e 9 teams and 5 racers left out. (:

Solve for each variable.

dem82 [27]

Answer:

a = 38⁰

b = 54⁰

c = 54⁰

Step-by-step explanation:

a + 142⁰ = 180⁰ because a straight line = 180⁰

b + 38⁰ + 88⁰ = 180⁰ because the angles of a triangle equal 180⁰, and the missing measurement = 38⁰ because it is a vertical angle to angle a

c + 88⁰ = 142⁰ because the angles are corresponding angles

11. Write the balanced equation for the reaction of HC2H3O2, with Al(OH)3 to form H2O and Al(C2H302)3:

Kamila [148]

Answer:

74.36 g of aluminium acetate.

730.27g of aluminium acetate.

- to the nearest hundredth.

Step-by-step explanation:

Acetic acid is usually written as CH3COOH.

a. 6CH3COOH + Al(OH)3 ---> Al(CH3COO)3 + 9H2O

So 6 moles of acetic acid produce 1 mole of aluminium acetate.

Using the molecular masses

6*( 1.008*4 + 12.011*2 + 16 *2) g acetic acid gives (26.98+3(36.032+ 2*12.011)

348.228 g acetic acid gives 207.142 g Al acetate.

So 125 g gives (207.142 / 348.228) * 125

= 74.36 g of aluminium acetate.

(26.98 + 3*16 + 3 * 1.008) g of Al(OH)3 gives 207.142 g Al acetate

78.004 g gives 207.142 g Al acetate

275 g gives (207.142 / 78.004) * 275

= 730.27g Al acetate.
