We need just to put y and z into polynomial, so
The answer is $126, you have to turn the percent into a decimal, then multiply that decimal by the $210. whatever you get from that, you subtract from $210
Estimate :
paycheck of 262....rounds to 300
tips :
130.....rounds to 100
62...rounds to 100
167...rounds to 200
total pay : 300 + 100 + 100 + 200 = 700
he spent 201.....rounds to 200
leaving him with (700 - 200) = 500 <== estimate
actual price...
262 + 130 + 62 + 167 - 201 = 621 - 201 = 420 <== actual
Answer:
Line NMLK: x = 13
Line STUF: x = 15
Step-by-step explanation:
Line NMLK:
Using our knowledge of algebra, we can turn this into an equation that is simpler. The full length of line NMLK is 23, so we will set the equation equal to 23. On the other side of the equation will be the remaining variables.
x - 6 + 9 + 2x - 19 = 23
Start by adding -19, -6, and 9 together to get:
x + 2x - 16 = 23
Add 16 to both sides and add the like variables together (x's).
3x = 39
39 ÷ 3 = 13
Therefore, x = 13.
To check we can plug it into our original equation
13 - 6 + 9 + 2(13) - 19 = 23
7 + 9 + 26 - 19 = 23
7 + 9 + 7 = 23
16 + 7 = 23
23 = 23
Therefore the answer checks out!
Line STUF
Now we will do the same with the line STUF.
13 + 6 + 2x - 18 = 4x - 29
We will add all like terms together.
1 + 2x = 4x - 29
Next we will subtract 2x from 4x.
1 = 2x - 29
Then we will add 29 to 1 which gives us:
30 = 2x
Divide by 2.
x = 15
Answer:
x + 4
Step-by-step explanation:
Noah's age = x
Jacob's age = x – 3
In seven years,
Jacob's age = x – 3 + 7
Jacob's age = x + 4
