In a way, you are adding like terms.
3.5 + 2.7 = 6.2, therefore making the answer 6.2 + x
The brackets can be ignored so you are really just asked 8 x 4 x k. 8 x 4 =32 so you end up with 32k
Answer:
all you have to do is graph them but put them in y=mx+b form first, the coordinates is the solution
Answer:
Number of large boxes: 55
Number of small boxes:65
Step-by-step explanation:
Let be "l" the number of large boxes and "s" the number of small boxes.
Set up a system of equations:
Use the methof of elimination. Mulitply the first equation by -60 and add both equations. Then solve for "s":
Substitute s=65 into any of the original equations and solve for "l":
Answer:
x=-2.4 or x= - 12/5
Step-by-step explanation:
hope that helps.
3x+y=−11
3x+y+−3x=−11+−3x(Add -3x to both sides)
y=−3x−11
2x+2y=−10
2x+2(−3x−11)=−10
−4x−22=−10(Simplify both sides of the equation)
−4x−22+22=−10+22(Add 22 to both sides)
−4x=12
−4x
−4
=
12
−4
(Divide both sides by -4)
x=−3
y=−3x−11
y=(−3)(−3)−11
y=−2(Simplify both sides of the equation)
Answer:
x=−3 and y=−2
D.(-3,-2)
