A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.
Part A
If she spends 3x + 5 dollars on the first order of light bulbs, which of the following represents how much she spends on the second order?
10x + 18
4x + 8
21x + 65
10x + 8
Part B
If the store owner spent a total of $90 on both orders, how much does a box of light bulbs cost in dollars? Enter the number in the box.
$
Answer:
Your answer is: X = 11
Your equation: 7x+30=90
If you subtract 7 from 90 you get 77.
If you divide 77 and 7 you get 11.

Peter, Bridget and Caroline share some sweets in the ratio 6:3:2. Peter gets 56 more sweets than Caroline. How many sweets are there altogether?
Answer:
The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets
Step-by-step explanation:
Ratios are a way of displaying the proportional split of a value and they are very similar to fractions. In the example above, we see that for every 2 sweets Amy has, Beth gets 3 and, Colin will get 4. Like fractions, this proportion will stay the same regardless of the scale of the ratio. The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets. So, what scale factor do we need to get it from a total of 9 sweets to a sum of 36 sweets? We know that 9 multiplied by 4 gives us 36, therefore, we can use a scale factor of 4. Remember how whatever is done to the denominator of a fraction has to be done to the numerator? Ratios like to behave the same way, so now that we have scaled up the sum of the ratio, we need to scale up the individual values by 4 – (2x4) : 3x4 : 4x4. Once we work it out we get the new ratio 8:12:16. You can check if you’re right by adding up the new values and you will see that 8 + 12 + 16 = 36, which is the value that the 9 was initially scaled up to. So we now know that when sharing the 36 sweets, Amy will get 8 sweets, Beth will get 12 sweets and Colin will get 16.

Darnell and Hector ride their bikes at constant speeds. Darnell leaves Hector’s house to bike home. He can bike the 8 miles in 32 minutes. Five minutes after Darnell leaves, Hector realizes that Darnell left his phone. Hector rides to catch up. He can ride to Darnell’s house in 24 minutes. Assuming they bike the same path, will Hector catch up to Darnell before he gets home?
Answer:
yes
Step-by-step explanation:
Even after 5 minutes, it will still take Darnell 27 more minutes to get home. If Hector can make it in 24 minutes, then he can catch up to Darnell before he gets home.

If you roll a 6-sided die 6 times, what is the best prediction possible for the number of times you will roll a two?
Answer:The best prediction is 1/6 of the times or one time of the six that you will roll a two..
This is because without any interference, each of the six numbers of the dice will have same theoretical probability (which is the probability or chances that is expected.

Answer:
Hope it helps you,
Step-by-step explanation:
As the figure can be split in to 3 geometric figure,
Rectangle , Triangle and Semi circle ,
So first find the area of these figures then add up them ,
Area of rectangle = Length * width
Length = 20m m and width = 14 mm
hence
Area of rectangle = 20*14 = 280 mm^2
Now ,
Are of Circle = [tex]\\ \pi *d^{2} /4[/tex]
Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]
Hence we have d= 20mm
Putt in semi circle formula we get,
Area of Semi Circle= (3.14)*400/8 = 157 mm^2
Now area of triangle = 1/2 * length*width
length =32-20 = 12 mm
width = 14 mm
putt in the formula we get ,
Area of triangle = 1/2*12*14 = 84 mm^2
Now add these 3 Areas to get total Area,
Total Area = 84+157+280 = 521 mm^2

help on numbers 4 5 6 plz help
Answer:
4) 6 students
5) 7 fewer students
6) No, you can not tell from the frequency table how many students ran a mile in exactly 12 minutes.
Step-by-step explanation:
4) you’d look at the row from 8:00-8:59.
5) Add the first two rows together (6+2=8), then subtract that by the sum of the last two rows (9+6=15), which is 7
6) There’s no pattern in the frequency table, and the data points would be plotted differently since it’d be from a range of times, not one set time.
Hope this helped, sorry if I’m wrong on #6 ;)

Daysi buys a video game on sale. If the video usually costs $30.00, and it
was on sale for 25% off, how much did Daysi pay?
Answer:
$22.5
Step-by-step explanation:
The original price is $30 and it's on sale for 25% off. Since 25% is a quarter of the total price, I divided 30÷4=7.5. $7.5 is 25% of $30, so 7.5 is the amount taken off the original price. To find what Daysi paid, I subtracted 30-7.5=22.5. $22.5 is the result after the 25% off, so Daysi paid $22.5.
