Answer:
Sarah has $18, and Lance has $42.
Step-by-step explanation:
We know that Sarah and Lance together have $60, so we can write the equation:
S + L = 60
We also know that Lance has six more than twice as much as Sarah, which can be expressed as:
L = 2S + 6
Now, we have a system of two equations:
S + L = 60
L = 2S + 6
We can use substitution or elimination to solve this system. Let's use substitution:
From equation 2, we can express L in terms of S:
L = 2S + 6
Now, substitute this expression for L into equation 1:
S + (2S + 6) = 60
Combine like terms:
3S + 6 = 60
Subtract 6 from both sides:
3S = 60 - 6
3S = 54
Now, divide by 3:
S = 54 / 3
S = 18
So, Sarah has $18.
Now, we can find Lance's amount using equation 2:
L = 2S + 6
L = 2(18) + 6
L = 36 + 6
L = 42
Lance has $42.
B. 4
C. 3
D. 8
Answer with explanation:
A regular polygon is simple closed geometrical shape, only made up of line segments.
And Regular Tessellation, is geometrical shape, made up of regular polygons having, 3 ,or 4 or 6 sides.
It is combination of, only single kind of polygon,either, polygon having 3 sides, or ,4 sides or 6 sides.
→Regular polygon having 3 sides is Called Equilateral Triangle.
→Regular polygon having 4 sides is Called Square.
→Regular polygon having 6 sides is Called Regular Hexagon.
⇒Regular polygon having , 8 sides will not form a regular tessellation.
Option D
Answer:8
Step-by-step explanation:
B. 4y^2+2=(4y+y)+2
C. 4y^2+2=4(y+y)+2
D.4y^2+2= 4(y×y)+2
3 lbs. for $6.90
Click on the correct answer.
Answer:
2 lbs. for $4.50
Step-by-step explanation:
Do a ratio
2 : 4.50
You want to see how much it cost per pound, so divide them by 2
2 ÷ 2 : 4.50 ÷ 2
1 : 2.25
So per pound, the hamburger will cost $ 2.25
________________________________________________________
3 : 6.90
You want to see how much it cost per pound, so all you need to do is divide them by 3
3 ÷ 3 : 6.90 ÷ 3
1 : 2.3
So for the first one, it cost 2.25 per pound, and for the second one, it cost 2.3 per pound....the one that is better will be 2.25 because it cost 5 cents less than the second one
Hope this helped!
Have a supercalifragilisticexpialidocious day!
