Answer:

15.

Step-by-step explanation:

Since 32 + 4 are in parenthesis, you'd do that first. 32 plus 4 equals 36, which subtracted from 42 is equal to 8. 8 plus 7 is 15. Therefore, your answer is 15.

I hope this helped, have a nice day.

Hello can someone please help me with this
HACTEHA [7]

Answer:

(c) is closest to the correct answer

Step-by-step explanation:

The question answers itself: "Mr. Jones's prescription calls for 1.04 tablets PER DAY, thus the amount of tablets Mr. Jones should talk daily are 1.04. Since none of the answers in the answer set have '1.04' in them, we have to use some basic logic:

The list of answers are, a) 1.25. We can rule that one out as it is not 1.04. We can also rule out b) and d) using the same logic. Thus, by process of elimination, we are left with c) 1 O. Not only is 1.0 (or just 1) the closest number to the actual amount (1.04) but it also makes the most sense, as one cannot take .04 (or 4/100ths) of a pill.

20 points<br> How on Earth am I supposed to do this
goblinko [34]

Answer: -89

Step-by-step explanation:

So your equation is

- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)

You know that (a) (b) and (c) = -1

You also know that (x) and (y) = 7

So, when you put this into the equation, it will look like this:

- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)

When you work that out you will get left with your answer, which is -89.

HOPE THIS HELPS!!!

Rachel really wants to purchase a new skateboard and her mother has agreed to give her a weekly allowance that she can save unti
Slav-nsk [51]

Answer:

Step-by-step explanation:

10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take

220/25=x

So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take

I dont understand what the second one is asking so sorry dude but I think that's right

At Meadowsweet restaurant, Kevin bought 2 burgers, 2 cake slices, and 1 soda. The burgers cost $1.75 each, the cake slices cost
Elenna [48]

Answer:

He should pay 30 quarters

Step-by-step explanation:

To find the number of quarter dollars he should pay, first calculate out the amount of money this would cost. For this, we can multiply the cost of the item by the number of them that we got and then add them all together.

Burgers

2 * 1.75 = 3.50

Cake

2 * 1.50 = 3.00

Soda

1 * 1.00 = 1.00

Total

3.50 + 3.00 + 1.00 = 7.50

Now to find out how many quarters he should pay, we divide the amount by .25.

7.50/.25 = 30
