Answer:
(7m + 10) yards of cloth was used
Step-by-step explanation:
This is a multiplication problem. Firstly, we are told that she sew m shirts and she used 2 yards of cloth for each of the shirts. The total amount of materials used here is m * 2 = 2m yards
She also sew another (m + 2) Shirts using 5 yards of materials for each of the shirts. The total amount of materials used is thus 5(m + 2) which equals (5m + 10) yards
The total amount of cloth used altogether is thus 2m + (5m + 10) = (7m + 10) yards of cloth
Answer:
true
Step-by-step explanation:
because when we subtract 18 and 4, the answer is 12. Hence, the value is less than 18
Answer:
7
Step-by-step explanation:
Q R
T S
I put the letters here in order, a clockwise order starting at Q.
If you look at our diagram you will see that RT and QS are actually the diagonals of this rectangle.
The diagonals of a rectangle are congruent.
We have the measurement of RT = the measurement of QS.
That is we have this equation: 4x-16=x+5.
4x-16=x+5
Subtract x on both sides:
3x-16= 5
Add 16 on both sides.
3x = 21
Divide both sides by 3.
x = 7
Answer:
(8+t)^2-6 when t=2
Step-by-step explanation:
1: (8+2)^2-6
2: (10)^2-6
3: 100-6
4: 94
The number of $5 notes is 10 and $50 notes is 6
Step-by-step explanation:
Let x be the number of $5 notes
and
y be the number of $50 notes
Then according to given statements
"The total number of notes used was 16."
x+y=16 Eqn 1
"A restaurant bill of $350 was paid using $5 notes and $50 notes."
5x+50y=350 Eqn 2

Putting x=10 in equation 1

So,
The number of $5 notes is 10 and $50 notes is 6
