2). (r + 17 = 51)
3). (7/9x =28)
4). (2/3x = 2)
5). { 3(x-2) = -9 }
6). (x -1.75 = 8.85)
7). Natalie buys organic almonds priced at $77 from the grocery store. How much did
she pay the cashier, if she received $23 in change?
Step-by-step explanation:
1. add 4 on both sides and it will be x=17
2. subtract 17 on both sides and it will be x= 34
3. multiply 9/7 on both sides and it will be x= 257/7 then you divide 257 by 7 then the final answer will be x= 36
4. multiply 3/2 on both sides and it will be x=6/2 then you divide 6 from 2 and the finial answer will be x= 3
5. you will distribute 3 into x and 2 and you will be 3x-6=-9 then you will add 6 on both sides so you will get 3x=3 and then divide 3 on both side so you will get x=1
6. add 1.75 on both sides so x= 10.6
7. the equation will be 23 +x = 77 so first you will subtract 23 on both sides and x will equal 54 so Natalie paid $54
2 = 8 / 4
8 / 4 - 1 / 4 = 7 / 4
They ate 7/4 lbs, or 1.75 lbs.
Considering the values of the digits in the number, we have that digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.
<h3>What are the values of the digits in the number 1,377,207?</h3>
We start counting the values from the final number, from 1 and multiplying by 10, hence:
- Digit 7 has a value of 1.
- Digit 0 has a value of 10.
- Digit 2 has a value of 100.
- Digit 7 has a value of 1,000.
- Digit 7 has a value of 10,000. -> Ten thousand place.
- Digit 3 has a value of 100,000.
- Digit 2 has a value of 1,000,000.
One tenth of the ten thousand place is a value of 100, hence digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.
