Expanding it, we get 1.3*8-1.3b+3.7b=-5.2 using the distributive property. Next, we get 10.4+2.4b=-5.2. Subtracting 10.4 to both sides, we get -15.6=2.4b. Dividing 2.4 from both sides, we get b=-15.6/2.4=-6.5
Answer:
4.8 lbs
Step-by-step explanation:
Candied pecan price: $14.00
Candied Cashew price: $10.00
Mixture price: $12.50
Candied cashew weight: x lbs
Candied pecan weight: 8 lbs
Mixture weight: y pounds
The sum of the weights of candied pecan and candied cashew must equal the weight of the mixture. While the mixture weight multiplied by the mixture price must equal the sum of each individual candy's weight multiplied by its price:
Multiplying the firs equation by -10 and adding it to the second one, gives us the value of "y" which can then be used to find "x":
Therefore, the grocer would need 4.8 pounds of candy cashews to make the mixture.

The two number are 39 and 13
<em><u>Solution:</u></em>
Let the two numbers be "a" and "b"
Let the larger number be "a" and the smaller number be "b"
<em><u>Given that, sum of two numbers is 52</u></em>
a + b = 52 ---------- eqn 1
<em><u>One number is 3 times as large as the other number</u></em>
Larger number = 3 times smaller number
a = 3b -------- eqn 2
<em><u>Let us solve eqn 1and eqn 2</u></em>
<em><u>Substitute eqn 2 in eqn 1</u></em>
3b + b = 52
4b = 52
b = 13
<em><u>Substitute b = 13 in eqn 2</u></em>
a = 3(13)
a = 39
Thus the two number are 39 and 13
