Answer:
y= 77
Step-by-step explanation:
<em>Write down the equation for direct proportion.</em>
y= kx, where k is a constant.
<em>Find the value of k.</em>
When x= 12, y= 84,
84= k(12)
12k= 84
k= 84 ÷12
k= 7
<em>Substitute</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>k</em><em> </em><em>into</em><em> </em><em>the</em><em> </em><em>equation</em><em>.</em>
y= 7x
When x=11,
y= 7(11)
y= 77
Answer:
since Norma sold 24 of the peanut butter squares that she baked and it is 80% of it. There is only 20% of the peanut butter squares she has baked. Leaving it to be only 6 peanut butter squares left.
This is because 24 is the 80% of 30. She had 30 in total and sold that 80% which is 24. So, therefore it leaves 6 peanut butter squares left. Making it 20% of what Norma baked.
Answer:
Step-by-step explanation:
Use Distributive Property: a*(b -c) = a*b - a*c
2(3 -4k) = 2*3 - 2*4k
= 6 - 8k
Answer:
c equal 11.40 Step-by-step explanation: c is the hypotenuse so under square root 9^2 +7^2
