<h3><u>The unknown number is equal to 4.</u></h3>
8x - 27 = 5
Add 27 to both sides.
8x = 32
Divide both sides by 8
x = 4
Answer:
-7.14
Step-by-step explanation:
Evaluate
−4.2(−2.8 + 4.5)
Open parenthesis
(-4.2 * -2.8) + (-4.2 * 4.5)
= (11.76) + (- 18.9)
= 11.76 - 18.9
= -7.14
NOTE:
Negative (-) × negative (-) = positive (+)
Positive (+) × positive (+) = positive (+)
Negative (-) × positive (+) = negative (-)
Positive (+) × negative (-) = negative (-)

Hey there! :D
7(2x+6)=1
Use the distributive property. Multiply each number by each other.
7*2x= 14x 7*6= 42
14x+42=1
Subtract 42 on both sides.
14x= -41
Divide both sides by 14.
We know that 14 goes into -41 almost three times.
14*3= 42 (there is one left over)
-2 13/14 (we just need one more part of 14)
That is the simplified number.
I hope this helps!

Answer:
I have no clue as to what the options were, but the answer is 61 and three-fifths.
Step-by-step explanation:
<em>Well, the fraction options were a little distorted, so I'll work it out anyway.</em>
<em />
7 • 8 4/5
7(8 + 4/5)
<em>7 • 8 is 56, and 7 • 4/5 is 28/5.</em>
56 + 28/5
<em>28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.</em>
56 + 5 + 3/5
61 + 3/5
61 3/5 (61 and three-fifths)
There!
<em>(Sorry about not getting the options...)</em>
