1/2 the weight of a brick +20= 1/3 the weight of a brick +30. What is the weight of the brick?

1 answer:

6 0

1/2x+20=1/3x+30
Subtract 20 on both sides
1/2x=1/3x+10
Subtract 1/3x on both sides
1/6x=10
Multiply by 6 on both sides
X=60

Solve for x and Y using the angles shown, please helppp

inna [77]

Answer:

Step-by-step explanation:

We have the vertical angles and supplementary angles.

Vertical angles are congruent. Therefore we have the equation:

$(1)\qquad14x+4=4y-8$

Supplementary angles add up to 180°. Therefore we have the equation:

$(2)\qquad(16x-4)+(14x+4)=180$

Solve (2):

$(16x-4)+(14x+4)=180\qquad\text{combine like terms}\\(16x+14x)+(-4+4)=180\\30x=180\qquad\text{divide both sides by 30}\\x=6$

Put the value of x to (1) and sole:

$4y-8=14(6)+4\\4y-8=84+4\\4y-8=88\qquad\text{add 8 to both sides}\\4y=96\qquad\text{divide both sides by 4}\\y=24$
