Step one: multiply and divide in order. Step two: add and subtract like terms. Step three: get X alone on one side (what you do to one side you have To do to the other side) Step four: simplify and solve :)

First×5×3×=15×
2nd 5×4=20
so 15x+20-2x= 13x+20 and the other side of the equation is 7
multiply -3×-2x=6x
multiply -3×11=-33
now rewrite equation
13x+20=6x-33
get values to left side and numbers to right side
13x-6x= -33-20 or 7x = -53
now ÷ by 7 x=8 6/7

Suppose that a1, a2, a3, . . . is an arithmetic sequence, in which a3 = 19 and a14 = 96. Find a1.
katovenus [111]
Uhhh I think you have to add 19 and 14 which shall give you the answer to a1 so it should be 33 but then I think you divide 33 and 96 or you will multiply 33 and 96

Evan is going to the 50th state fair this weekend, it cost $10 to enter and each ride is $2. Create a linear function that could
alexgriva [62]

Answer:

y represents the total amount he spent in x amount of rides+ the $10 fee.

Step-by-step explanation:

At x=0, y=10 because he needs to pay $10 to enter, and he haven't rode on anything yet.

x=1, y=12

x=2, y=14

x=3, y=16

... and so on.

Substitution method please
JulijaS [17]

Answer:

x = 3, y = -2

Step-by-step explanation:

Solving the bottom equation for y, we have y = 4 - 2x. Substitute that into the top equation, and solve for x.

4x - 3(4 -2x) = 18

4x - 12 + 6x = 18

10x - 12 = 18

10x = 30

x = 3

From this, we have y = 4 - 2(3) = 4 - 6 = -2
