Answer:

The x coordinate of the solution is 0

Step-by-step explanation:

y = –2x – 1 and y = 3x–1

Solve for x using substitution method

Replace y with -2x-1 in second equation

-2x-1 = 3x-1

Add 2x from both sides

-1= 5x - 1

add 1 on both sides

0=5x

Divide by 5 from both sides

x=0

The x coordinate of the solution is 0

A construction company needs new materials for the next job. It needs to purchase three wood beams. Each beam costs $45.25. The
Lena [83]
Answer: $210.75

Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75

Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75

Taylor has saved $99 for a tablet. That is 45% of the cost of the tablet. How much does the tablet cost?
gayaneshka [121]

Answer:

$220

Step-by-step explanation:

Make a proportion

We know that 99 over some number (x) must equal 45%

99/x=45/100

Cross multiply

45x=9,900

Divide by 45 on both sides

x=220

So, the tablet costs $220

Hope this helps! :)
