Use substitution to solve the system of equations
snow_tiger [21]
You plug in x+1.75 into the second equation to get 4x-2(x+1.75)=4. Once you simplify and solve that problem for x you should get x = 3.75. Plug the x-value that you got back into one of the equations (y=x+1.75) or (4x-2y=4). Either way your y-value should be 5.5.
Your answer would be A. because (x,y) or (3.75,5.5) in this case

Mason wrote the expression shown below 5(y+2). Write an expression that is equivalent to Mason’s expression
rusak2 [61]

Answer:

5y+10

Step-by-step explanation:

The best way to rewrite this equation is to use the distributive property.

5y+10

Or, we can just use the commutative property to switch the numbers around, but I recommend the distributive.

5(2+y)

Hope this helps!

A b and c lie on a straight line given that angle y = 125 and angle z = 313 work out x
inysia [295]

Answer:

∠x = 78

Step-by-step explanation:

∠y + ∠1 = 180

=> 125 + ∠1 = 180

=> ∠1 = 180 - 125

=> ∠1 = 55

∠z + ∠2 = 360

=> 313 + ∠2 = 360

=> ∠2 = 360-313

=> ∠2 = 47

∠1 + ∠2 + ∠x = 180

=> 55 + 47 + ∠x = 180

=> ∠x = 180 - 55 - 47

=> ∠x = 78
