Answer:
x=2 and y=-3
Step-by-step explanation:
y=-3x+3, 4x+3y=-1 solve using substitution
y=-3x+3 solve y=-3x+3 for y
4x+3y=-1
4x+3(-3x+3)=-1 simplify both sides of the equation
-5x+9=-1
-5x+9-9=-1+-9 add -9 to both sides
-5x=-10
-5x/5=-10/-5 divide both sides by -5
x=2
substitute 2 for x in y=-3x+3
y=(-3)(2)+3
y=-3 simplify both sides of the equation
answer; x=2 and y=-3

Answer:
An isosceles triangle is symmetrical and a right triangle has a 90 degree angle and not symmetrical so they are not the same.

Answer:
82
Step-by-step explanation:
Vertical rectangle:
A = bh
A = (5)(10)
A = 50
Horizontal rectangle:
h = 10 - (3 + 3)
h = 4
A = bh
A = (8)(4)
A = 32
Combined:
50 + 32
82
Answer:
[tex]A=82 meters^2[/tex]
Step-by-step explanation:
First we will split the shape into two rectangles.
Now that it is in two separate peaces, solve each one individually
Remember [tex]A = l*w[/tex]
[tex]10*5=50[/tex]
[tex]8*4=32[/tex]
Finally add the two areas together
[tex]50+32=82[/tex]

Step-by-step explanation:
7 whole enchiladas he can make with 5/6 jars of sauce.
Given that, Tony is making chicken enchiladas. He needs 1/8 jar of sauce for each enchilada.
We need to find out how many whole enchiladas can he make with 5/6 jars of sauce.
How to divide two fractions?The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
Based on the given condition we can formulate: 5/6 ÷ 1/8
=5/6 × 8
=5/3 × 4
= 20/3
=6.666≈7
Therefore, 7 whole enchiladas he can make with 5/6 jars of sauce.

B. 27
C. 18
D. 64
80 points!!
We know that,
[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]
l = length of sideLet's find out the side first. We know that,
[tex]\bigstar \: \boxed{\sf {T.S.A_{(Cube)} = 6\ell^2}} \\ [/tex]
According to the question,
[tex] \longmapsto \sf {54 = 6\ell^2 } [/tex]
[tex] \longmapsto \sf {\dfrac{54}{6} = \ell^2 } [/tex]
[tex] \longmapsto \sf {9 = \ell^2 } [/tex]
[tex] \longmapsto \sf {\sqrt{9} = \ell } [/tex]
[tex] \longmapsto \sf \red{3 \: units = \ell } [/tex]
Now, calculating volume :
[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]
→ Volume = l × l × l
→ Volume = 3 × 3 × 3
→ Volume = 27
