Answer:
-27
Step-by-step explanation:
6^2=36
36/-4=-9
36/-2=-18
-9+-18=-9-18=-27
Answer:
y = -6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75y−1.5y+0.5=5
0.75y+−1.5y+0.5=5
(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)
−0.75y+0.5=5
−0.75y+0.5=5
Step 2: Subtract 0.5 from both sides.
−0.75y+0.5−0.5=5−0.5
−0.75y=4.5
Step 3: Divide both sides by -0.75.
Hope this helps!

Answer:
0.2
Step-by-step explanation:
<u>Question 7:
Define x :
</u>
Let the digit in the ones place be x.
The digit in the tens place is x+2.
The sum of the digit and its reverse is 66
<u>Find x:</u>
10(x + 2) + x + 10x + (x + 2) = 66
10x + 20 + x + 10x + x + 2 = 66
22x + 22 = 66
22x = 44
x = 2
<u>Find the number:</u>
The number in the ones place = x= 2
The number in the tens place = x = 2 + 2 = 4
Answer : The number is 42.
<u>Question 8:</u>
<u>Define x:</u>
Let the digit in the tens place be x.
The digit in the ones place is x+7.
The number = 10x + x + 7 = 11x + 7
If the digit interchange,
the number = 10(x + 7) + x = 10x + 70 + x = 11x + 70
<u>Find x:
</u>
9(11x + 7) = 2(11x + 70)
99x + 63 = 22x + 140
99x - 22x = 140 - 63
77x = 77
x = 1
<u>Find the number:
</u>
x = 1
x + 7 = 1 + 7 = 8
So the number is 18
Answer: The number is 18.
