Kyle asks his friend Jane to guess his age and his grandmother’s age. Kyle says his grandmother is not more than 80 years old. He says his grandmother’s age is, at most, 3 years less than 3 times his own age.

Jane writes this system of inequalities to represent k, Kyle’s age, and g, Kyle’s grandmother’s age.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

i dont know the answer but here's a picture of a dog

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
