\bf \cfrac{3}{5}\div \cfrac{-4}{9}\implies \cfrac{3}{5}\cdot \cfrac{9}{-4}\implies \cfrac{27}{-20}\implies -1\frac{7}{20}

5. -2 = p - 1<br> Help me pleaseee
dangina [55]
Assuming you are trying to find the value of p:

You would add 1 to each side to make the p alone

-2 =p - 1
+1 +1

-1 = p


To check, you can put p in the original equation

-2 = -1 - 1

-2 = -2 which means this is correct


Hope this helps! If you can, please give brainlist! :)

Answer Choices: a) slope=-3 b)slope=-1/3 c)1/3
Leto [7]

Answer:

A) -3

Step-by-step explanation:

If you move down three times and once to the right, you get the next point.

Slope = rise/run

It rises -3 units and run 1. So -3/1 which can be simplified to just -3

How do you answer a, b and c, answers and also how you worked it out
Kruka [31]

We can either convert to standard form first or convert to a common multiplier, kinda like a common denominator.  The latter makes more sense if they wanted the result in scientific notation, but let's do it that way anyway.

a)

4.5 × 10⁴ + 3.8  × 10³ = 45 × 10³ + 3.8  × 10³ = 48.8× 10³ = 48,800

Answer:  48,800

b)

4.5 × 10⁴ - 3.8  × 10³ = 45 × 10³ - 3.8  × 10³ = 41.2× 10³ = 41,200

Answer:  41,200

c)

7.2 × 10⁻³ + 6.3  × 10⁻² = 7.2 × 10⁻³ + 63  × 10⁻³ = 70.2 × 10⁻³

       = 7.02 × 10⁻² = 0.0702

Answer: 0.0702

Solve the expression and find the value of x.
vovangra [49]

\large\underline{\sf{Solution-}}

\sf \dfrac{x + 1}{10}  -  \dfrac{3(x - 1)}{5}  = 2

\sf\longmapsto  \dfrac{x + 1}{10}  -  \dfrac{3x - 3}{5}  = 2

\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10}   = 2

\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10}  = 2

\sf\longmapsto  \dfrac{x + 1 - 6x + 6}{10}  = 2

\sf\longmapsto \dfrac{ - 5x + 7}{10}  = 2

\sf\longmapsto - 5x + 7 = 20

\sf\longmapsto - 5x = 20 - 7

\sf\longmapsto - 5x = 13

\sf\therefore x =  -  \dfrac{13}{5}

Hence, the value of x will be -13/5 respectively.
