Answer:
72
Step-by-step explanation:
<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>
<em>6 to 7 can also be express as 6/7</em>
<em>Thus, we can set up a proportion</em>
<em>6/7 = x/84</em>
<em>Now, we have to solve for x</em>
<em>x = 72</em>
<em>Hence, if there were 84 robin there would be 72 blue jays.</em>

Answer:
angle JKL is 106
Step-by-step explanation:
an isosceles triangle means two sides are the same and the bottom two angles are the same length. So you would equal the two equations and solve it to get x. Then replace one of the equation's x with the number you got, which would be 5, and solve that. Since both bottom angle are the same, the other angle would be the same degree, 37*. A triangle is 180* total, so subtract that by two 37's and you'll get the answer.
8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
Answer:
x=10
Step-by-step explanation:
43 and (4x+3) are vertical angles, which mean they are equal
so, 43=(4x+3)
43-3=(4x+3-3)
40=(4x)
40/4=4x/4
10=x
