Answer:

2.5 - 1.2x < 6.5 - 3.2x

add 3.2x to both sides;

2.5 + 2x < 6.5

minus 2.5 from both sides;

2x < 4

 x < 2

Step-by-step explanation:

This is the exact same as doing a linear equation, so brush up on this skill.

Answer:      x<2   or   xϵ(-∞; 2)

Step-by-step explanation:

Add +3.2x to both sides of inequality:

2.5-1.2x+3.2x<6.5-3.2x+3.2x

2.5+2x<6.5

Deduct 2.5 from both sides of inequality:

2.5-2.5+2x<6.5-2.5

2x<4

Divide both sides of inequality by 2

2x/2<4/2

x<2   or   xϵ(-∞; 2) ( the answer can be written in 2 ways)

Find the slope of the line passing through the points (–1, 3) and (4, –7).
Anit [1.1K]
Slope is rise over run, i.e., y over x. So, to find slope, take your y values and subtract them. It doesn't matter which one first, just make sure whatever you decide matches with the way you subtract your x values. So, for this, I'll do 3 - -7. Subtracting a negative makes a positive, so you have 10. Do the same to your x values. -1 - 4 is -5. Now, you have the fraction 10/-5, which simplifies to -2. Your slope, therefore, is -2. Hope this helps!

Question 3 options:
Grace [21]

Answer:

90

Step-by-step explanation:

Given: Measure of one side of equilateral triangle = 9+3x

Measure of another side of equilateral triangle = 5x-5

In equilateral triangle all three sides are equal in length.Therefore,

5x-5 =9+3x

5x-3x=9+5

2x=14

x=\frac{14}{2} =7

On substituting the value of x in side of equilateral triangle,

One side of equilateral triangle = 5x-5=\left (5(7)-5 \right )=(35-5)=30

Perimeter of equilateral triangle = 3 ( length of one side) ........( given)

perimeter of equilateral triangle = 3\times30 = 90.

Which is bigger 7/8 or 0.78
agasfer [191]
<span>7/8 = 7 * 1/8 and 1/8 = 1 : 8 = 0.125. After that: 7 * 0.125 = 0.875. Finally, 0.875 > 0.78. We can do it also by transforming 0.78 to fraction: 0.78 = 78/100 = 39/50 and then multiplying the numerator and the denominator by 4: 39/50 = 156 / 200 . Then we will also multiply 7/8 * 25/25 = 175/ 200. Obviously: 175/200 > 156/200. Answer: 7/8 is bigger than 0.78. </span>
