Jasmine bought 1.3 pounds of ham and 0.8 pounds of cheese from the deli and paid $11.28. She went back the following week and bo
LuckyWell [14K]
Let

x
be the price for a pound of ham
y the price for a pound of cheese

<span>1.3x +0.8y = 11.28  ....(1)
1.5x +1.2y = 14.76  ....(2)

Lets multiply (1) by -1.2
Lets multiply (2) by 0.8

-1.56x -0.96y = -13.536 .....(3)
</span> 1.2x + 0.96y = 11.808 .....(4)


If we add (3) and (4)

-0.36x = -1.728 ............> x = 4.8

We substitute in (1)

1.3(4.8) +0.8y = 11.28

y = 6.3

Price per pound of ham = x = 4.8
Price per pound of cheese = y = 6.3

Andrew [12]

Answer:

W\leq 6.4\ m

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

P=2(L+W)

we know that

L=7.6\ m

P\leq28\ m

substitute

2(7.6+W)\leq28

solve for W

(7.6+W)\leq14

W\leq14-7.6

W\leq 6.4\ m

At a military function, three cannons are fired at intervals of 12
Morgarella [4.7K]

Answer:

144 seconds

Step-by-step explanation:

To do solve this question, we must find the LCM (least common multiple) of 12, 16, and 18.

Let's start by prime factorizing (finding the prime factors) all the numbers.

12\rightarrow3*4\rightarrow2*2*3

16\rightarrow4*4\rightarrow2*2*2*2

18\rightarrow2*9\rightarrow2*3*3

Now, we must find the greatest quantity of each [prime] number and multiply them together to obtain the least common multiple.

Upon further evaluation of the [prime] factors, we can see that we need four 2s and two 3s. Therefore...

2*2*2*2*3*3=2^4*3^2=16*9=144

They will be fired together again after 144 seconds.
