I would say it's H because 4 and 3 add to be 7
Answer:
Step-by-step explanation:
Answer: x=15
Step-by-step explanation:
To solve problems like this you need to simplify the equations on both sides and then isolate your variable x.
Problem 3: Let x = price of bag of pretzels Let y = price of box of granola bars
We have Lesley's purchase: 4x+2y=13.50
And Landon's: 1x+5y=17.55
We can use the elimination method. Let's negate Landon's purchase by multiplying by -1. -1x-5y=-17.55
We add this four times to Lesley's purchase to eliminate the x variable.
2y-20y=13.50-70.2
-18y=-56.7
y = $3.15 = Price of box of granola bars
Plug back into Landon's purchase to solve for pretzels.
x+5*3.15=17.55
x+15.75=17.55
x = $1.80 = price of bag of pretzels
Problem 4.
Let w = number of wood bats sold
Let m = number of metal bats sold
From sales information we have: w + m = 23
24w+30m=606
Substitution works well here. Solve for w in the first equation, w = 23 - m, and plug this into the second.
24*(23-m)+30m=606
552-24m+30m=606
6m=54
m=9 = number of metal bats sold
Therefore since w = 23-m, w = 23-9 = 14. 14 wooden bats were sold.
Answer:
135,000 times
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
<u>We need to know the size of your bakery store. </u>
As we can see, the entire shopping center is: 45000 square feet and your shop is 1/10 of that space
=> Your shop area is: 45000*1/10 = 4500 square feet
In the question, they want to know how many thirtieths of the space does it take up, so let say thirtieths in numerical is: 1/30
Hence, the number of thirtieths it takes:
= 
= 135,000 times
Hope it will find you well.
