Answer:
-1/5
Step-by-step explanation:
Perpendicular line is the negative inverse of the straight line.
So 5=-1/5
Length of base of isosceles triangle, x = 7
Step-by-step explanation:
- Step 1: Given base of isosceles triangle, x = 7 and perimeter = 41
Length of one leg = 3x - 4. Since two sides, other than the base of an isosceles triangle are equal, the length of the other leg = 3x - 4.
- Step 2: Formula for perimeter of triangle = length of sides
- Step 3: Substitute values of sides in the formula
⇒ 41 = x + (3x - 4) + (3x - 4) = x + 2(3x - 4)
⇒ 41 = x + 6x - 8
⇒ 41 = 7x - 8
⇒ 49 = 7x
⇒ x = 7
Answer:
the answer is c,Yes, because the ratios for each input and output are equivalent.
Step-by-step explanation:
Answer:
$3x+$5y=C and the total cost is $ 78
Step-by-step explanation:
the equation first is going to be $3x+$5y=C
x: small balloons
y: large balloons
c: total cost
Now to find the how much the total cost is, you should substitute the variables and then solve the equation.
x: 11
y:9
3(11)+5(9)= 33+45
78
