Answer:
66 pieces of candy.
Step-by-step explanation:
First I set up the equation: (c/6)-4 = 7
c represents the candy she started with.
6 represent when she split the candy
4 is the number of pieces she has eaten
7 is the number of pieces she has left
after setting up the equation, you want to add four to the other side to get 11
c/6 = 7+4 --> c/6 = 11
Then you want to multiply by 6 to get ride of the fraction to get a total of 66 pieces of candy.
c = 11 x 6 --> c = 66
Answer: It's going to be a 3x2. Im assuming its [ 5 10 on the first row, second row would be -2, -4, then the bottom row would be 1, 2] Hope I helped!
Step-by-step explanation:
Answer:side one is 8cm
Side 2 is 8cm
Side 3 is 15 cm
Step-by-step explanation:
The perimeter of a shape is the distance around the shape. The perimeter of a triangle is the sum of the sides of the triangle.
Let x represent the length of side one and side 2. Since they have equal length, the sum of their length is x + x = 2x cm
Side three is one cm shorter then twice the length of side one. This means that the length of side three would be 2x - 1
The perimeter of a triangle is 31cm. Therefore,
2x + 2x - 1 = 31
4x - 1 = 31
4x = 31 + 1 = 32
x = 32/4 = 8 cm
Side three = 2×8 - 1 = 16 - 1 = 15
