Yes, 1 & 2 are correct. 3 would be explaining how you got your answers. For example, you could use number 1 and say you thought about 10 x 3 equals 30 so 3 groups with 8 left over and so on or however your thought process went.
Answer: the length of each of the congruent sides is 29 inches.
The length of the third side is 22 inches.
Step-by-step explanation:
In an isosceles triangle, two sides are equal. The base angles are also equal.
Let x represent the Length of each of the congruent side.
The congruent sides are 7 inches longer than the third side of the triangle. This means that the length of the third side of the triangle is
x - 7
The formula for determining the perimeter of a triangle is
a + b + c
Where a, b and c are the length of each side of the triangle.
If the isosceles triangle has a perimeter of 80 inches, it means that
x + x + x - 7 = 80
3x - 7 = 80
3x = 80 + 7 = 87
x = 87/3 = 29 inches
The length if the third side would be
29 - 7 = 22 inches

Step-by-step explanation:
Answer:
3.75 cups of baking soda are needed to make 2 and 1/2 batches of the cleaning product
Step-by-step explanation:
This question can be solved by a rule of three.
A recipe says that 1 and 3/4 cups of baking soda are needed to make one batch of a homemade cleaning product.
1 + 3/4 cups = 1 + 0.75 = 1.75 cups for one batch.
How many total cups of baking soda are needed to make 2 and 1/2 batches of the cleaning product?
2 and 1/2 batches is 2 + 0.5 = 2.5 batches.
1.75 cups for one batch. How many cups for 2.5 batches? So
1 batch - 1.5 cups
2.5 batches - x cups
c = 2.5*1.5 = 3.75
3.75 cups of baking soda are needed to make 2 and 1/2 batches of the cleaning product
