After watching baking shows on T. V. , Sanjay signs up for a cake-decorating class. To practice his new skills, he decorates a batch of cupcakes with sugar flowers. Sanjay puts 4 sugar flowers on each cupcake. In all, Sanjay puts 32 sugar flowers on the cupcakes. Which equation can you use to find the number of cupcakes c Sanjay decorates?
Answer:
4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation
number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)n = 32/4n = 8The equation that can be use to determine the number of cupcakes c Tucker decorates will be 4n = 32.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that 4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation;
The number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)
n = 32/4
n = 8

Jim is going to plant grass in a rectangular area that is 15 feet long and 10 feet wide.At the store, there are bags of grass and seed that will cover 200 square feet. Willone bag be enough
The area of the plant grass is the amount of plant grass on the field
It is true that one bag of grass and seed will be enough
How to determine if the bag will be enough?
The dimension of the rectangular area is:
15 feet by 10 feet
So, the area of the rectangular garden is:
Area = 15 feet * 10 feet
Evaluate the product
Area = 150 square feet
There are bags of grass and seed that will cover 200 square feet.
200 square feet is greater than 150 square feet
Hence, one bag of grass and seed will be enough

Triangle ABC is isosceles, with AB = AC.
r\1180
Work out the size of angle x.
Help!!!
x = 180 - 118 ( linear angles)
x = 62
62+62+y = 180
y = 56
Answer:
Step-by-step explanation:
Angle of a straight line = 180 degrees :)
So to find x you would do:
x = 180 - 118 = 62
Also the angle sum of a triangle = 180 degrees.
Since it is an isosceles triangle, the bottom two angles would be equal:
Angle sum of triangle = 180
x + x + y = 180
Since we know x = 62, substitute it into the above equation:
62 + 62 + y = 180
124 + y = 180
Subtract 124 from both sides to solve for y.
y = 180 - 124
y = 56
