In a there will be 1 solution as 7x and 5x + 2 is the same and in b there will be 2 solutions as they both are 2 different questions hope this helped
It's kinda like using variables, but shapes in their place. Let's set the circle to x, the triangle to y, and the square to z. Now the equations say x+(y+z)=13, (y+z)=8, and x+y=7. First thing we can do it plug 8 into the first equation for y+z, getting x+8=13. Subtract 8 to both sides and x (or circle) equals 5. Plug 5 into the last equation, x+y=7 to solve for y, getting 5+y=7. Subtract 5 to both sides and y (or triangle) equals 2. Finally, plug two in for y in y+z=8, getting 2+z=8. Subtract 2 from both sides and z (or square) equals 6. Hope I've explained it clearly!!

Answer:
125
Step-by-step explanation:
we have
x*.28= 35
we divide both sides by .28 and get
x= 125
and 28% of 125 = 35
Hope it helps !
