Solve the equation. 33 = p – 6.71<br> A. –39.71 <br> B. –26.29 <br> C. 39.71 <br> D. 26.29
jeka57 [31]

<u>Answer</u>

C. 39.71


<u>Explanation</u>

33 = p - 6.71

The first step is to make the like terms to be on the same side.

Add 6.71 on both sides of the eqution

33 +  6.71 = p - 6.71 + 6.71

39.71 = p


∴ p = 39.71

Daniela is 23 years older than her daughter. in 5 years, their ages will total 63. how old are they now?
pshichka [43]
Both their ages totaled in 5 (years) - 5 (years)

63 - 5 = 58

Current ages totaled = 58 (years)

Daniela is 23 years older than her daughter (as given above) so...

Current ages totaled (58 years) - How many years Daniela is older than her daughter ( 23 years )

58 - 23 = 35

So, Daniela’s age is currently 35 years and her daughter’s age would be 23 years.

The slope-intercept form of the equation of a line that passes through point (-2,-13) is y=5x-3. What is the point-slope form of
marissa [1.9K]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

<h3>Point - slope form of equation: </h3>

        \sf \boxed{\bf y - y_1=m(x-x_1)}

Slope intercept of the line : y =5x - 3

Comparing with y = mx +b , m =slope = 5

m = 5 and Point (-2 ,-13)

     y - [-13] = 5(x - [-2])

     y + 13 = 5(x + 2)
