The Sum of 4 times one number and 3 times the second number is 65. The sum if the 2 numbers is 18. What are the numbers and equations you used

Answers

Answer 1

Answer: 4x + 3y = 65
X + y = 18

When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11

X+y = 18
11 + y = 18
Y = 7

Answers

Answer:

The total cost for 1.5 pounds of apples is $5.25

Step-by-step explanation:

To find the total cost using partial products, you can do the following:

Calculate the cost for 1 pound of apples, which is $3.50.

Since Zoe bought 1.5 pounds of apples, you can use partial products to find the total cost:

First, calculate the cost for 1 pound: $3.50.

Next, calculate the cost for 0.5 pounds (half of 1 pound), which is half of $3.50: $3.50 / 2 = $1.75.

Finally, add the cost for 1 pound and 0.5 pounds to find the total price: $3.50 + $1.75 = $5.25.

So, the total cost for 1.5 pounds of apples is $5.25.

If 3x – 10 = 17, what is the value of 6x + 20 ?

Answers

$3x-10=17\ \ \ \ /+10\n\n3x-10+10=17+10\n\n3x=27\ \ \ \ /:3\n\n3x:3=27:3\n\nx=9\n\n\n\n6x+20=6\cdot9+20=54+20=74$

$3x-10=17\ \ \ /\cdot2\n\n2\cdot3x-2\cdot10=2\cdot17\n\n6x-20=34\ \ \ \ /+40\n\n6x-20+40=34+40\n\n6x+20=74$

74 because 3x equal 17+10. so x equals 9 and plug it in to the equation got 74

If you bought something in Colorado for $80, you would be charged $2.32 in state sales tax. What is the state sales tax in Colorado?

The state sales tax in Colorado is 2.9%.

We know that because we divide 2.32/80. We have to find out what percent the tax is of the amount paid. The answer comes to 0.029. Multiply it by 100, and you get 2.9%
