Answer:

B. x = -1

Step-by-step explanation:

-3(x - 2) = 9

Divide both sides by the coefficient of (x - 2) which is -3

$\frac{-3(x - 2)}{-3} =\frac{9}{-3}$

x - 2 = -3

Add 2 to both sides of the equation

x - 2 + 2 = -3 + 2

x = -1

Hope this helps :)

Sheila bought burgers and fries for her children and some friends. the burgers cost $2.05 each and the fries are $.85 each. she

jeyben [28]

Let's have B stand for burgers, and F stand for fries.
2.05B+0.85F=$19.10 - This equation is set equal to total price.
B+F=14 - This equation is set equal to total number of items.
Subtract the F in the bottom equation.
B=14-F
Put this in place of B in the first equation.
2.05(14-F)+0.85F=19.10
Make sure you distribute the 2.05 properly, over both the 14 and the F.
28.7 - 2.05F+0.85F=19.10
Collect like terms for the F values.
28.7 - 1.2F=19.10
Subtract 28.7 from both sides.
-1.2F=-9.6
Divide by -1.2 on both sides.
F=8
Put this value in place of F in either equation.
B+8=14
B=6
So F=8 and B=6.

# 14 Q. Write a congruence

MrRissso [65]

The first is the correct
Δ ZYB ≈ Δ OWR by SSS
because:
                ZB = OR = 5
                ZY = OW = 3
                YB = WR = 5.5

System of Equations y=-x-1 y+x=3 Solve?

ozzi

Solve by substitution

$\sf{y=-x-1}$
$\sf{y+x=3}$

Just plug in y=-x-1 into y+x=3

So we get:

$\sf{(-x-1)+x=3}$

Simplify that:

$\sf{-1=3}$

And since that is not true, that means this system of equations has no solutions!
