3x500 = 1,500 3x80=240 3x4 =12 1,500+240+12 = 1,752

My guess would be: 3 x(times) 500+80+4

Prove that in any triangle the length of a side is less than the half of the perimeter in statement reason format.

horrorfan [7]

Answer:

Proved

Step-by-step explanation:

I am going to pose c as the largest side in a random triangle

If so then remember that, by the triangle inequality, a + b > c. Let's start from there...

Statement: | Reasoning:

1. a + b > c 1. Triangle Inequality

2. a + b + c > c + c (adding c on both sides), 2. Algebra + Def. Of Perimeter

a + b + c > 2c (simplified)

Perimeter > 2c (definition of perimeter)

c < 1/2 * Perimeter

Hi! Can anybody help me with these problems? I have to do 2 step equations.

Dovator [93]

1) 3.8x + 5.2x - 6.7 = 11.3
9x = 11.3 + 6.7
9x = 18
x = 18/9
x = 2

2) 7.8y - 4.9 - 5.4y = 2.3
2.4y = 7.2
y = 7.2/2.4
y = 3

3)

$\frac{2}{3} x - 5 = 1$
$\frac{2}{3} x = 5 + 1$
$\frac{2}{3} x = 6$

Multiply by 3 by both sides:

$3 \times \frac{2}{3} x = 3 \times 6$

Simplify:

2x = 18
x = 18/2
x = 9

4)

$\frac{7}{5} y = 3 - \frac{1}{5}$

Do lowest common denominator:

$\frac{7}{5} y = \frac{(5 \times 3) - 1}{5}$
$\frac{7}{5} y = \frac{15 - 1}{5}$
$\frac{7}{5} y = \frac{14}{5}$

Simplify by 5 by both sides:

$7y = 14$
$y = \frac{14}{7}$
$y = 2$

The graph shows the distance Julian drives on a trip. What is Julian's speed?

lilavasa [31]

Answer:

B. 80 km/h

Step-by-step explanation:

The graph is linear and goes through the origin, so distance is proportional to time, and the constant of proportionality is speed. The desired answer can be read from the point on the graph at time = 1 hour: 80 km.

Julian's speed is 80 kilometers per hour.
