Answer:
B
Step-by-step explanation:
<h3>The constant of variation is
</h3><h3>The equation is
</h3>
<em><u>Solution:</u></em>
Given that,
The conversion of square feet to square yards can be represented by direct variation
Let y represent the number of square yards
Let x be the number of square feet
y = kx ------ eqn 1
Where, "k" is the constant of variation
Three square yards are equivalent to 27 square feet
Substitute, y = 3 and x = 27 in eqn 1
Thus the constant of variation is
<em><u>What is the equation representing the direct variation?</u></em>
Substitute k = 1/9 in eqn 1
Thus the equation is found
In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6
We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1
Both solutions meet the condition.
Answer:
A.) 6
B.) 24
C.) $60
Step-by-step explanation:
Given that :
Cost of Mango = $2
Purchase of 6 mangoes earns 2 free mangoes
(a) Robin purchased $36.00 worth of mangoes.
How many free mangoes did Robin get?
$36 / price per Mango
$36 / $2 = 18 mangoes
18 / 6 = 3
Hence, free mangoes (3 * 2) = 6 free mangoes
(b) How many mangoes did he get all together?
18 mangoes + 6 mangoes = 24 mangoes
(c) Peter also bought mangoes. He received 40 mangoes. How much did Peter pay?
Set of mangoes purchased:
40/ (6 + 2) = 40/8 = 5 sets of mangoes
Hence, amount paid :
2 * 6 * 5 sets
$60
