Answer:
The car arrived at 10:10
Step-by-step explanation:
1. Break up the time the journal took to make it easier
9:45 + 15 minutes = 10:00
10:00 + 10 minutes = 10:10
2. Check your answer
10 + 15 = 25 minutes total
Answer:
312.5
Step-by-step explanation:
25 x 2, for two weeks of work = 50
50 x 6.25 = 312.5
Simplifying
12x + -8x = 12
Combine like terms: 12x + -8x = 4x
4x = 12
Solving
4x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x = 3
Simplifying
x = 3

To find perimeter of triangles, use the formula P = a + b + c, where a, b, and c are the sides of the triangle.
For this triangle, you are given two sides and the perimeter and asked to find the third side. To do that, plug the given values into the formula for perimeter and solve.
P = a + b + c
10.8 = 3.5 + 2.6 + c
10.8 = 6.1 + c
4.7 = c
The measure of the third side of the triangle is 4.7 cm.

The perimeter of a quadrilateral is the sum of the length of its four sides. So to find the perimeter, simply add all the sides together. As you need to find a missing side, follow the same steps as above to find the missing side.
15.3 = 2.7 + 4.7 + 3.3 + x
15.3 = 10.7 + x
4.6 = x
The length of the missing side of the quadrilateral is 4.6 cm.
Hi,
4 > 0, it's correct so 4 is a solution.
0 < 7
, the same as the first.
