Answer:
y= -2x+14
Step-by-step explanation:
the slope is -2 and the y intercept is 14
Answer:
y=1/2x+5
Step-by-step explanation:
Answer:
91in^2
Step-by-step explanation:
SA of base = 7x7 = 49in^2
SA of each triangle = 1/2 x 7 x 3 = 10.5in^2
SA of all 4 triangles = 10.5 x 4 = 42in^2
SA Total = 49 + 42.= 91inch^2
Let's write out the problem with the triangles as "x" and the ovals as a number. Since there are 3 triangles and 5 boxes in the first box, the first box would be:
3x+5
In the other box, there are 11 ovals, so:
11
With this, they are equal, so:
3x+5=11
To solve this, move the 5 over onto the other side by subtracting 5 from each side:
3x+5<em>-5</em><em> </em>= 11<em>-5</em>
Then you have:
3x = 6
Now, divide doth sides by 3 to isolate x:
3x/3= 6/3
Now you're done!
<u><em>x=2</em></u>
Hope that helps.
