If you would like to write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck, you can calculate this using the following steps:
X ... the amount of Alicia's paycheck
X/2 - $42.15 >= $20
X/2 >= $20 + $42.15
X/2 >= $62.15 /*2
X >= $62.15 * 2
X >= $124.3
The correct result would be <span>X >= $124.3</span>.
Answer:
Line S
Step-by-step explanation:
Because Line R and Line S don't meet and dont intersect.
I hope this helps! I'm sorry if it's wrong.
Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
Alrighty, let's think of it like this: You are trying to fill a box with a bunch of sports balls. You have tiny little golf balls, and you have giant bowling balls. You need to fill this same box all the way up.
If you fill it with the tiny golf balls, you are going to need a <em>whole lot of them!</em>
If you are putting in bowling balls, only a few of them will fit, because they are so much bigger.
When it comes to your fraction, the box is the the number 8/10. That number will not change because we are not changing the size of the box.
We are just changing what we are filling it with. Manny, can fit 8 parts, or in this case balls, into the box.
It says Ana uses fewer parts, so she cannot fit as many in as Manny.
This means that Manny would have the golf balls, since he can fit more in than Ana, who must have the bowling balls.
So which is bigger? A bowling ball or a golf ball?
A bowling ball, which is what Ana has. So <u><em>Ana's part will be bigger</em></u> in size.
So,
Start with 7.
Multiply by 2.
7 * 2 = 14
Multiply by 2.
14 * 2 = 28
Multiply by 2.
28 * 2 = 56
Multiply by 2.
56 * 2 = 112
Multiply by 2.
112 * 2 = 224
Multiply by 2.
224 * 2 = 448
Multiply by 2.
448 * 2 = 896
Multiply by 2.
896 * 2 = 1792
Multiply by 2.
1792 * 2 = 3584
The first ten terms in the pattern are:
7, 14, 28, 56, 112, 224, 448, 896, 1792, 3584
In a function:
f(x) = 2x
In a rule:
S = {x| x/7 = Whole Number}
