nadezda [96]

Answer:

Step-by-step explanation:

If BOTH equations are in slope-intercept form then the-graphing-? method would be best, but the-substitution-? method would also be effective since both y's are already by itself.

If ONE of the equations is solved for x or y and the other equation is not, then the-substitution-? method is best.

If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-elimination--? method.

If BOTH equations are lined up in standard form the elimination method would be best. But if the coefficient of x or y is 1, then the-substitution--? method is also effective.

A baby giraffe was born at a wildlife preserve. The giraffe was 6 feet tall when it was born, and it grew 1.75 feet over the nex
HACTEHA [7]

The age of the giraffe when he is 15 feet tall be 1 year 1 month and  16 days.

<h3>What is fraction?</h3>

A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Giraffe height = 6 feet

Height grew in 7 months= 1.75 feet

Giraffe's height in 7 month = 7.75 feet

Giraffe's height, 1 feet= \frac{7}{7.75} month

                                   = 0.9032 months

Giraffe's height, 15 feet=  0.9032 x 15 month

                                    = 13.548 month

                                    = 13 months 16 days approx.

                                    = 1 year 1 month 16 days

Hence, the age of giraffe will be 1 year, 1 month and 16 days

A family is purchasing concrete in order to create a foundation for a rectangular outdoor
Murrr4er [49]

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.
