Which expression is equivalent to 4(x + 3) - 2(-x - 5)?
Answer:
the last one because when using the distributive property, you get
4x + 12 - 2x - 10
Answer:
4x + 12 + 2x + 10
Step-by-step explanation:
4( x + 3 ) -2( -x -5 )
1. Multiply 4 and x = 4x
2. Multiply 4 and 3 = 12
3. Multiply -2 and -x = 2x
(turns positive as there are 2 negative signs)
4. Multiply -2 and -5 = 10
(turns positive as there are 2 negative signs)
Beula has a collection of video games. There are 12 games in the collection, and 2/4 of them are console games. Beula decides to double the amount of console games. 1. How many console games are in the collection now? 2. What fraction the games are console games now?
Answer:
12 console games
Step-by-step explanation:
if 2/4 are console games when you have 12, that means 6/12 are console games so to double the amount, add 6. 12+6=18.
12 out of the 18 are now console games making console games 6/9 (2/3 simplified) of the game collection.

On each of Maggie’s bird-watching trips, she has seen at least 36 birds. If she has taken 3 of these trips each year over the past 15 years, at least how many birds has Maggie seen?
Answer:
Maggie has seen at least 1620 birds.
Step-by-step explanation:
Ok since Maggie sees 36 birds each trip that means she sees 108 birds every year since she takes 3 trips each year. 36×3=108
If she has been doing this for 15 years she has seen at least 1620 birds because 108×15=1620
Raoul is trying to find a new way to keep track of coffee beans. He can fit 1,000 beans in a tub, 100 beans in a large bag, and 10 beans in a small bag. He leaves any group of 9 or less on his counter. If Raoul has 2 tubs, 3 large bags, 1 small bag, and 5 beans on the counter, how many coffee beans does Raoul have altogether?
Answer:
2,315 coffee beans.
Step-by-step explanation:
1 tub = 1,000
1 large bag= 100
1 small bag = 10
Raoul has:
- 2 tubs
- 3 large bags
- 1 small bag
- 5 beans on the counter
2 x 1,000 = 2,000
3 x 100 = 300
10 + 5 = 15
then, add all of the (bold) numbers together.
2,000 + 300= 2,300
2,300 + 15 = 2,315
Raoul has 2,315 beans altogether.

Answer:
Option 4
Step-by-step explanation:
Finding Area
The area of the semicircle is
[tex](\pi/2)(4^2) \approx (3.14/2)(16)=25.12[/tex]
The area of the trapezoid is
[tex]\frac{1}{2}(8+20)(8)=112[/tex]
Adding these, we get the area to be about 137.12 square inches.
Finding Perimeter
The arc length of the semicircle is
[tex]\pi(4) \approx 3.14(4)=12.56[/tex]
The sum of the lengths of the outer sides of the trapezoid is
[tex]10+10+20=40[/tex]
Adding these, we get the area to be about 52.56 inches.

Piper paid for 3 boxes of cookies to be
delivered to her house.
• Each box of cookies cost $24.95.
• Piper paid $12.99 for delivery.
What is the total amount Piper paid?
Answer:
Total Amount Paid by Piper = $84.87
Option C is correct.
Step-by-step explanation:
Total boxes of cookies = 3
Cost of 1 box of cookie = $24.95
Delivery charges paid = $12.99
We need to find total amount Piper paid.
First we will find cost of 3 boxes of cookies:
Cost of 1 box of cookie = $24.95
Cost of 3 box of cookie = $24.95 x 3
= $74.85
Now, add cost of 3 boxes of cookies with delivery charges paid to get total amount paid.
Total Amount Paid = Cost of 3 box of cookie + Delivery charges paid
= 74.85 + 12.99
= 87.84
So, Total Amount Paid by Piper = $84.87
Option C is correct.

9 · 7 = 63
Answer:
B- 3/10
Step-by-step explanation:
9/14 x 7/15
multiply across so you would now get 63/210 and we can divide the top and bottom by 21 so it will simplify to 3/10

Approximating
1. Approximate to the nearest tenth: v45
Approximation to the nearest tenth means to find the tense place . e.g.
25632 - in this case the '32'
then you round it upwards or downwards according to rule that if digit at once place is
from 0 - 4 you round downwards,
from 5 - 9 you round upwards for example
25632 goes to 25630
248 goes to 250
Therefore approximate to nearest tenth means to make the number a nearest multiple of 10 with respect to the rule that if digit at once place is
from 0 - 4 you round downwards,
from 5 - 9 you round upwards
Look at the next place value to the right to round a number to the nearest tenth (the hundredths). Remove all the digits to the right if it's 4 or less. If it's 5 or higher, add 1 to the digit in the tenths place before removing all the digits to the right.

Equation: x*0.35=y
Step-by-step explanation:
Find the unit rate for all and compare
1.05/3=0.35
1.75/5=0.35
2.8/8=0.35
Since they are all equal, there proportional
Answer:
y = 0.35x
Step-by-step explanation:
Jane:
Cost of 3 postcards= $1.05
Cost of 1 post card = 1.05 ÷ 3
= $ 0.35
Rosi:
Cost of 5 postcards= $1.75
Cost of 1 post card = 1.75 ÷ 5
= $ 0.35
Tanya:
Cost of 8 postcards= $2.80
Cost of 1 post card = 2.80 ÷ 8
= $ 0.35
As unit rate is same, Cost and number of postcards are in proportion.
Cost of cards = 0.35 * number of cards
y = 0.35*x
y = 0.35x
Justin has $28 to buy a gift for his cousin, Julianne. He found something to buy that costs $24. He knows he has to also pay 8% in sales tax and he is trying to decide if he can afford it. Will he have enough money to buy the item and if so how much will he pay?
Justin will have enough money to buy the item. The amount Justin will pay is $25.92.
How much will Justin pay?A sales tax is the amount of tax that is charged on the sales of goods and services. Tax is the compulsory sum levied by the government or an agent of the government on goods and services. Taxes increase the price of an item.
Percentage is the fraction of an amount expressed as a number out of hundred. The sign used to represent percentages is %.
Amount Justin would pay for the item = (1 + tax) x initial cost of the item
(1 + 0,08) x $24
= 1.08 x 24 = $25.92
$25.92 is less than the amount Justin has for the gift. This means that Justin has enough money to buy the gift.

3/5 divided by 2 1/2
Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.
So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.
Remember that dividing by a fractions means the same thing
as multiplying by the reciprocal of that fraction.
