3.5x is lessthan or equal to 21
3.5x<=21 divide by 3.5
x<=6 so that means the length of the rectangle can be 6 or less.
Answer:
7 9/14
Step-by-step explanation:
The girls ate 8 1/7 of a pie, so we mark G=8 1/7
The boys ate 1/2 of a pie, so we mark B=1/2
The girls ate the more pies, so we do this:
G-B
We plug the G and the B in, and it is 8 1/7-1/2
We change it to the common denominator, which is 14. We have 8 2/14- 7/14
we take a one and add 14 to 2 and we have this:
7 16/14-7/14
and that equals 7 9/14
Answer:
-1, -4, 2, 4
Step-by-step explanation:
The are ascending
The given triangle is isosceles, so the two remaining angles in the triangle both have measure <em>xº</em>. The interior angles of any triangle sum to 180º, so that
58º + <em>xº</em> + <em>xº</em> = 180º
58 + 2<em>x</em> = 180
2<em>x</em> = 122
<em>x</em> = 61
Angles <em>y</em> and <em>z</em> are supplementary to angle <em>x</em>, so that
<em>xº</em> + <em>yº</em> = 180º
and
<em>xº</em> + <em>zº</em> = 180º
and consequently, <em>y</em> = <em>z</em>. In particular, we get
<em>y</em> = 180 - 61
<em>y</em> = 119
and so
<em>z</em> = 119
