Please help me

Answer:

a)

<u>The equation would be:</u>

  • 3x + 2 = 7*2

b)

Step 1. <u>Subtract 2 from both sides:</u>

  • 3x = 6*2

Step 2. <u>Divide both sides by 3:</u>

  • 3x/3 = 6*2/3
  • x = 2*2

c)

  • A single box weights x= 4 units.

Enter the number that belongs in the green box
OLga [1]

Answer:

x=96°

y=96°

Step-by-step explanation:

y=84° because of vertical angles. the measure of all 4 angles added together is 360°, so we add the 84° and the other 84° angle, and subtract them from 360° to get the sum of the other two angles

360°-(84°+84°)=192°

divide 192° by 2 to get the measure of one angle

therefore, x=96°
