How do u add 10 to 2 digits numbers

2 answers:

7 0

When adding 10 to any two digit number, increase the left digit by 1. For example 20+10= 30. 55+10=65. If a problem says 10+ (a number), you can reverse the order the numbers are in because of the commutative property of addition. Example: 10+50 eqauls 50+10. Both equations equal 60. Also, Rodney would have 39 pieces of fruit since 20+19 is 39.

It depends. Multiples of 10 are:
10, 20, 30, 40, 50...........
And a 2 digit number can be anything between 10 and 99.

To comment: Rodney would have 39 pieces of fruit.

One side of a triangle is 2 times the second side. The third side is 5 ft longer than the second side. The perimeter of a triang

TiliK225 [7]

Answer:

The length of each side of triangle are 19 ft, 24 ft and 38 ft.

Step-by-step explanation:

Let the length of second side be x.

Now given:

Length of first side is 2 times length of second side.

Length of first side = 2x

Also, Length of third side is 5 ft longer than the second side.

Length of third side = 5+x

Perimeter of triangle = 81 ft.

We need to find the length of each side.

Now perimeter of triangle is sum of all three sides of triangle.

Therefore;

Perimeter of triangle = Length of first side + length of second side + Length of third side.

$2x+x+5+x=81 ft\\4x+5=81ft\\4x= 81 -5 ft\\4x = 76ft\\x= \frac{76}{4} = 19 ft$

Length of Second Side = 19 ft.

Length of First side = $2x= 2\times19 = 38 ft$

Length of Third side = $5+x= 5+19=24ft$

Hence the Length of triangles are 19 ft,38 ft,24 ft.

AleksandrR [38]

In y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = -2x + 2....slope = -2 and y int = 2
y = -2x - 3.....slope = -2 and y int = -3

when u have 2 lines that both have the same slope but different y intercepts, u have parallel lines with no solution because ur lines never intersect.

so ur answer is : no solutions or 0 solutions
