Answer:
- Son washed more
- Remaining 9/28 of the laundry
Step-by-step explanation:
<u>Make denominators common to see the difference in fractions:</u>
Son washed more laundry as 12/28 > 7/28
<u>Together they washed:</u>
- 7/28 + 12/28 = 19/28 of the laundry
<u>Remaining part is:</u>
- 1 - 19/28 =
- 28/28 - 19/28 =
- 9/28 of the laundry
Answer:
To prove:
X+Y.Z=(X+Y).(X+Z)
Taking R.H.S
= (X+Y).(X+Z)
By distributive law
= X.X+X.Z+X.Y+Y.Z --- (1)
From Boolean algebra
X.X = X
X.Y+X.Z = X.(Y+Z)
Using these in (1)
=X+X(Y+Z)+Y.Z
=X(1+(Y+Z)+Y.Z --- (2)
As we know (1+X) = 1
Then (2) becomes
=X.1+Y.Z
=X+Y.Z
Which is equal to R.H.S
Hence proved,
X+Y.Z=(X+Y).(X+Z)
Answer: Last option
(42÷2) +5
Step-by-step explanation:
We know that Mr. Roberts drove 42 miles on Monday.
On Tuesday Mr. Roberts drove half of what he drove on Monday plus 5 miles.
If we want to know how many miles Mr. Roberts drove on Tuesday then we should divide 42÷2 to find half of 42.
Then we know that in addition to the 21 miles he drove 5 more miles. Then we add 21 +5 = 26 miles.
So the expression that gives us the number of miles that Mr. Roberts drove on Tuesday is:
(42÷2) +5
Answer:
M + $13.72 = $58.22
Step-by-step explanation:
Manny and Sam combined (+) have a total (=) of $58.22
M + S = $58.22
M + $13.72 = $58.22
Answer:
x = -7
Step-by-step explanation:
−30=5(x+1)
Divide each side by 5
-30/5=5/5(x+1)
-6 =x+1
Subtract 1 from each side
-6-1 = x+1-1
-7 =x
