There are 80.5 tens in 805
Answer:
They completed 13, 3 credit classes
Step-by-step explanation:
1. Make 2 formulas. In this case: x+y=18
and 3x+4y=59
2. Then multiply x+y=18 by 3 and subtract the two equations.
Find y which is 5 and input into the equations. Then find your answer.
Answer:
Slope: -3/4
y-intercept: (0,-5)
Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
Answer:
b(a+c) this is answer okay
So represent the ages as x y and z with each being numbers
x+y+z=21
x times y times z=75
this is really tough for elementary school
one way is to find the factors of 75 or the numbers that add up to 75 and trial and error
use whole numbers becuase this is the world of math so
75=1 times 3 times 5 times 5
possible ages are
3,5,5
1,5,15
1,3,25
add them up
3+5+5=13
1+5+15=21 check
1+3+25=29
their ages are 1, 5 and 15
