Answer:
15/3 + (6.5 + 4.2) - 0.6 = 15.1
Step-by-step explanation:
You can first reduce the fraction to 5 when you multiply by 3, then calculate what's in the parenthesis. So now you have 5 + 10.7 - 0.6, then just solve from left to right. Hope this helps
-16, +2 are two nhmbers that multiply to -32 and add to -14
20x+5y=120
10x+7.5y=80 multiply this one by 2
___________
20x+5y=120
20x+15y=160 subtract
___________
-10y=-40 divide both sides by -10
____________
y=4
20x+5(4)=120 plug 4 in for y in the first equation
20x+20=120 multiply
20x=100 subtract
x=5 divide to find x
Answer:
Step-by-step explanation:
y*1/x
y=k/x where k is the constant of variation
when y=7, x=-4
7=k/-4
k=-28
when x=5
y=-28/5
note: * is used as symbol of variation
