Multiply, then you get 2a - 10 = -2. Then isolate the variable by adding 10 on both sides. you get 2a = 8. divide both by 2 and you get a = 4

Multiply 2 and a, then 2 and 5.
Rewrite.
Subtract 10 from both sides.
Rewrite.
Divide both sides by 2.
Rewrite.
You get your final answer!!

The table shows the Grades that students received on a test what fraction of the students scored an A or B on the test
Triss [41]
Okay. So, 15% is 15/100 and 33% is 33/100. 15 + 33 is 48. You leave the denominator the same, so the fraction is 48/100. However, the fraction needs to be simplified. Whatever you do to the numerator, we must do to the denominator. We can divide both numbers by 4 to get the simplified fraction form. 48/4 is 12. 100/4 is 25. There. The simplified fraction is 12/25. The answer is H: 12/25.

Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp and do the order of operation
umka21 [38]

Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

( \frac{2}{3}  -  \frac{1}{4} ) + ( \frac{1}{2}  \times  \frac{1}{3} )

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

\frac{2}{3}  -  \frac{1}{4}  =  \frac{8 - 3}{12}  =  \frac{5}{12}

Next multiply the other terms in the other bracket

That's

\frac{1}{2}  \times  \frac{1}{3}   =  \frac{1}{6}

Add both results

That's

\frac{5}{12}  +  \frac{1}{6}

Find the LCM

The LCM is 12

We get the final answer as

\frac{5}{12}  +  \frac{1}{6}  =  \frac{5 + 2}{12}  =  \frac{7}{12}

Hope this helps you

at a basketball game, a vendor sold a combined total of 218 sodas and hotdogs. The number of hotdogs sold was 50 less than the n
velikii [3]

9514 1404 393

Answer:

  • 134 soda
  • 84 hot dogs

Step-by-step explanation:

Let s represent the number of sodas sold. Then the number of hot dogs sold is (s-50) and the total is ...

  s +(s -50) = 218

  2s = 268 . . . . . . . . . add 50

  s = 134 . . . . . . . divide by 2

134 sodas were sold; 84 hot dogs were sold.
