1/7 = -3/2w -4/5
add 4/5 to both sides
1/7 + 4/5= -3/2w
change to common denominator; 5 & 7 go into 35
(1*5)/35 + (4*7)/34= -3/2w
5/35 + 28/35= -3/2w
33/35= -3/2w
divide by -3/2 on both sides; multiply by the reciprocal of -3/2
33/35 * -2/3= w
-66/105= w
simplify by 3
-22/35= w

CHECK:
1/7 = -3/2w - 4/5
1/7= -3/2(-22/35) - 4/5
1/7= 66/70 - 4/5
1/7= 66/70 - 56/70
1/7= 10/70
1/7= 1/7

ANSWER: w= -22/35

Hope this helps! :)

Each pair of shapes is congruent. Identify a transformation or sequence of transformations that could take one
Tema [17]

Answer:

When one shape can become another using only Turns, Flips and/or Slides, then the two shapes are Congruent. Two shapes are Similar when we need to Resize for one shape to become another (we may also Turn, Flip and/or Slide). So, when one shape can become another using transformation, the two shapes might be Congruent or just Similar?

Answer:

(3, 7)

Step-by-step explanation:
