Hey, TailsIsTheBest!
Great question=)

Question:<span>What is the value of the expression f2 + 8 if f = 7?

Answer:22

Work:They already gave us the value of the variable f, so all we have to do it plug in 7 for f's place. 

(7)2+8
7*2=14
14+8=22

I hope this helps;)
If you have any questions on my work, feel free to ask me.

If the values are placed right next to each other without a symbol, then you multiply them. 
So, you multiply the value of 7 with 2, since they are placed right next to each other. 
(7x2) + 8 = 14 + 8 = 22

Evaluate the expression. 5^2−4⋅6+11 Enter your answer in the box.
mart [117]

Explanation:

This question's it's about the order of operations. P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right.

Do exponents first.

5^2=5*5=25

25-4*6+11

Then, multiply left to right.

4*6=24

25-24+11

And add/subtract left to right.

25-24=1

1+11=12

\boxed{=12}

Hope this helps!

Thanks!

Have a great day!

After arianna completed some work, she figured she still had 78 21/100 pictures to paint. if she completed another 34 23/25 pict
dezoksy [38]

Subtract the number she completed from what she had left to paint originally.

The fractions have different denominators so first step is to rewrite the fractions with a common denominator.

23/25 can be rewritten as 92/100

Now you have 78 21/100 - 34 92/100

Because 21/100 is smaller than 92/100 subtract 1 whole number from 78 and rewrite 1 as 100/100 and add that to the fraction.

78 21/100 becomes 77 121/100

Now subtract :

77 121/100 - 34 92/100

77-34 = 43

And 121/100 - 92/100 = 29/100

Combine to get 43 and 29/100

Solve for j.<br> J + 22/8 =8
Monica [59]

Answer:

j=5.25

Step-by-step explanation:

j+22/8=8

j=8/1-22/8

j=64-22/8

j=5.25

Proof:

5.25+22/8=8

525/100+22/8=8

4200+2200/800=8

6400/800=8

8=8
