Answer:
-8b - 5k + 9
Step-by-step explanation:
=(-4b + 15 - 7k) - (6 + 4b - 2k)
Taking away the brackets
=-4b + 15 - 7k - 6 - 4b + 2k
collecting like terms
=-4b - 4b - 7k + 2k + 15 - 6
= -8b - 5k + 11
startfraction 1.55 over 1 endfraction is x = 1.55

What is ratio?</h3>
A ratio in mathematics shows how many times one number is included in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is identical to the ratio 4:3). (i.e., 8:6, which is identical to 4:3). The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). (or 4:7). A ratio can have any number of values, such as counts of people or things or measures of length, weight, time, etc. In most cases, both numbers must be positive.
EXPLANATION:
Sadly, we are unable to view the list of equations from which you can choose. But if we assume that x Equals the cost of 3.5 kg of grapes, we can construct the following equation
1/1.55 = 3.5/x
x = 1.55

Answer:
Area = 27√3/4 square units
Step-by-step explanation:
Since the shape is an equilateral triangle, all the sides will be equal
Area of the triangle = 1/2 * base * height
Get the height
(3√3)² = h²+(3√3/2)²
27 = h² + (27/4)
h²= 27 - 27/4
h² = 27 - 6.75
h² = 20.25
h = √2025/100
h = 45/10
Area = 1/2 * 3√3 * 45/10
Area = 135√3/20
Area = 27√3/4 square units
