Answer:
0.7, 7/8, 1 7/10, 1.78
Step-by-step explanation:
Use a calculator to find the decimal value of each fraction and put the decimals in order.
Area of a rectangle is 27 cm²
Given:
Perimeter of a rectangle = 24 cm
Length = 3x
Width = x
p = 2(l + w)
24 = 2(3x + x)
24 = 6x + 2x
24 = 8x
24/8 = x
3 = x
Width = 3 cm ; Length = 3x = 3(3) = 9 cm
Area = length * width
= 9cm * 3 cm
Area = 27 cm²
6x + 8 = 2x + 4
- 2x
4x + 8 = 4
- 8
4x = -4
÷ 4
x = -1
So the answer is B. -1. I hope this helps!
Answer:
- sugar cookies -- $4
- oatmeal cookies -- $8
Step-by-step explanation:
Using "s" and "o" to represent the prices of packs of sugar and oatmeal cookies, respectively, we can write the revenue equations as ...
10s +2o = 56
9s +3o = 60
In standard form (with common factors removed), these equations are ...
5s + o = 28
3s + o = 20
Subtracting the second equation from the first, we find ...
(5s +o) -(3s +o) = (28) -(20)
2s = 8 . . . . simplify
s = 4
Substituting into the first equation, we have ...
5·4 +o = 28
o = 8 . . . . . . subtract 20
The price of a pack of sugar cookies is $4; of oatmeal cookies, $8.
