Answers
Answer:
$0.14 less to pay this week.
Step-by-step explanation:
Given:
Cans of black beans usually cost $1.34 each.
This week they are on sale for 5 cans for $6.00.
You bought one can last week and one can this week.
Now, to find the amount more or less to pay this week.
So, we use unitary method to get the price of can this week:
If, 5 cans cost this week = $6.00.
Then, 1 can cost this week =
Thus, the cans of black beans cost $1.20 this week.
And, last week the cans cost $1.34 each.
So, the cost of can this week is less than last week.
Now, we get the difference in the cost of can of this week than last week by subtracting the cost of can last week from cost of can last week:
Therefore, $0.14 less to pay this week.

Answer:
Length of an isosceles triangle is, 3.12 m
Step-by-step explanation:
Given: Perimeter of an isosceles triangle is 15.6 m.
Let a be the length of sides and b be the base of an isosceles triangle respectively.
To find the length of the sides(a);
Isosceles triangle is a triangle with two equal sides and two equal base angles.
Perimeter of the isosceles triangle is the sum of the three sides i,e
Perimeter(P) = a +b +a = 2a +b
also it is given that; the base is 3 m bigger than a leg.
⇒ b = 3 a
Substitute this in perimeter formula;
P = 2a +3a =5a
Substitute the value of perimeter = 15.6 m
we have;
Divide both sides by 5 we get;
Simplify;
a = 3.12 m
Therefore, the length of the sides of an isosceles triangle is, 3.12 m
Answer:
The legs are 4.2m long.
The base is 7.2m long.
Step-by-step explanation:
x=leg
y=base
We can write two equations with the information given.
y=x+3
2x+y=15.6
We can solve this as a system of equations.
y=x+3
-(2x+y=15.6) - make the bottom equation negative.
-2x=x-12.6 - add the bottom to the top, canceling out the y.
-2x+12.6=x - add 12.6 to both sides.
12.6=3x - add 2x to both sides.
4.2=x - divide both sides by 3.
x=4.2
Now we can solve for y.
y=x+3
y=(4.2)+3 - substitute in the x.
y=7.2
