Answer:
6.8
Step-by-step explanation:
negative 2 times negative 3 is -6.
negative 2 times negative 0.4 is -0.8.
add them together :)
Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:
In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
(X-3)(X+1)=0
X-3=0
X=3
X+1=0
X=-1
Answer:
12. if 3/5 of them like chocolate ice cream 2/5 don't and 2/5 of 20 is 8.
A=8
13. 296 divided by 8 is 37
A=37
14. 123 divided by 7 is 17.5714285714 so each child will get 17 sweets and there will be 4 left over.
A=17 remainder of 4
15. umm i don't know just multiple 4.50 by the amount of soccer balls

Brainlest please

Answer:
Look Below, if I'm wrong then ignore this answer.
Step-by-step explanation:
If we were to use the formula y=mx+b, 2/3 is the slope and (0,-1) is the y intercept, so the x intercept must be about (1.5,0), so the graph is probably
